The THTR-300 was a thorium cycle high-temperature nuclear reactor rated at 300 MW electric (THTR-300) in Hamm -Uentrop, Germany. It started operating in 1983, synchronized with the grid in 1985, operated at full power in February 1987 and was shut down September 1, 1989. The THTR-300 served as a prototype high-temperature reactor (HTR) to use the TRISO pebble fuel produced by the AVR , an experimental pebble bed operated by VEW (Vereinigte Elektrizitätswerke Westfalen) . The THTR-300 cost € 2.05 billion and was predicted to cost an additional €425 million through December 2009 in decommissioning and other associated costs. The German state of North Rhine Westphalia , Federal Republic of Germany, and Hochtemperatur-Kernkraftwerk GmbH (HKG) financed the THTR-300’s construction.

68-885: On 4 June 1974, the Council of the European Communities established the Joint Undertaking "Hochtemperatur-Kernkraftwerk GmbH" (HKG). The electrical generation part of the THTR-300 was finished late due to ever-newer requirements and licensing procedures. It was constructed in Hamm-Uentrop from 1970 to 1983 by Hochtemperatur-Kernkraftwerk GmbH (HKG). Heinz Riesenhuber , Federal Secretary of Research at that time, inaugurated it, and it first went critical on September 13, 1983. It started generating electricity on April 9, 1985, but did not receive permission from

136-516: A Union action or position". In late 2023 and early 2024, unanimity voting on foreign affairs issues by the Council made headlines due to the resistance of Viktor Orbán , Prime Minister of Hungary , to passing European Union aid to Ukraine. In this recent example, the Council came to a unified conclusion after discussions with the Hungarian leader; previously at the end of 2023, Orbán had left

204-466: A common agenda, although only one formally holds the presidency for the normal six-month period. For example, the President for the second half of 2007, Portugal, was the second in a trio of states alongside Germany and Slovenia with whom Portugal had been co-operating. The Council meets in various configurations (as outlined below) so its membership changes depending upon the issue. The person chairing

272-493: A director-general. The Committee of Permanent Representatives (COREPER) is a body composed of representatives from the states (ambassadors, civil servants etc.) who meet each week to prepare the work and tasks of the Council. It monitors and co-ordinates work and deals with the Parliament on co-decision legislation. It is divided into two groups of the representatives (Coreper II) and their deputies (Coreper I). Agriculture

340-792: A proposal to pass. In a few limited areas the Council may initiate new EU law itself. The General Secretariat of the Council of the European Union , also known as Council Secretariat , assists the Council of the European Union, the Presidency of the Council of the European Union , the European Council and the President of the European Council . The Secretariat is headed by the Secretary-General of

408-534: Is a "sensitive" issue (according to EUR-Lex ). An exception to this rule exists via Article 31 of the Treaty on European Union , which stipulates circumstances in which qualified majority voting is permissible for the Council in discussing Common Foreign and Security Policy. Article 31 lays out provisions regarding a passerelle clause as well as the possibilities for Member State abstentions. Additionally, Article 31 stipulates derogation for "a decision defining

476-493: Is an instrument which is focused at a particular person or group and is directly applicable. Institutions may also issue recommendations and opinions which are merely non-binding declarations. The Council votes in one of three ways; unanimity , simple majority , or qualified majority . In most cases, the Council votes on issues by qualified majority voting , meaning that there must be a minimum of 55% of member states agreeing (at least 15) who together represent at least 65% of

544-538: Is binding on all EU states who must follow and defend the policy, which is regularly revised. A joint action refers to a co-ordinated action of the states to deploy resources to achieve an objective, for example for mine clearing or to combat the spread of small arms . Common strategies defined an objective and commits the EUs resources to that task for four years. The Council must practice unanimity when voting on foreign affairs issues because Common Foreign and Security Policy

612-513: Is dealt with separately by the Special Committee on Agriculture (SCA). The numerous working parties submit their reports to the Council through Coreper or SCA. The Treaty of Lisbon mandated a change in voting system from 1 November 2014 for most cases to double majority Qualified Majority Voting , replacing the voting weights system. Decisions made by the council have to be taken by 55% of member states representing at least 65% of

680-511: Is however chaired by the Union's High Representative . Its decisions are made by qualified majority voting in most areas, unanimity in others, or just simple majority for procedural issues. Usually where it operates unanimously, it only needs to consult the Parliament. However, in most areas the ordinary legislative procedure applies meaning both Council and Parliament share legislative and budgetary powers equally, meaning both have to agree for

748-575: Is in practice divided into several different council configurations (or '(con)formations'). Article 16(6) of the Treaty on European Union provides: The Council shall meet in different configurations, the list of which shall be adopted in accordance with Article 236 of the Treaty on the Functioning of the European Union. The General Affairs Council shall ensure consistency in the work of the different Council configurations. It shall prepare and ensure

816-485: Is similar to a configuration of the Council and operates in a similar way, but is composed of the national leaders ( heads of government or state ) and has its own President, since 2019, Charles Michel . The body's purpose is to define the general "impetus" of the Union. The European Council deals with the major issues such as the appointment of the President of the European Commission who takes part in

884-648: Is the third of the seven Institutions of the European Union (EU) as listed in the Treaty on European Union . It is one of two legislative bodies and together with the European Parliament serves to amend and approve, or veto, the proposals of the European Commission , which holds the right of initiative . The Council of the European Union and the European Council are the only EU institutions that are explicitly intergovernmental , that is, forums whose attendees express and represent

952-471: The Council of the European Communities , which would act as a single Council for all three institutions. In 1993, the Council adopted the name 'Council of the European Union', following the establishment of the European Union by the Maastricht Treaty . That treaty strengthened the Council, with the addition of more intergovernmental elements in the three pillars system. However, at the same time

1020-700: The General Affairs Council configuration, in agreement with the President-elect of the Commissission, adopts a list of candidates for the Commission proposed by the member states. The EU's legislative authority is divided between the Council, the Parliament and the Commission. As the relationships and powers of these institutions have developed, various legislative procedures have been created for adopting laws. In early times,

1088-931: The Lex building in 2008, the three aforementioned buildings are no longer in use by the Council services. When the Council is meeting in Luxembourg City, it meets in the Kirchberg Conference Centre , and its offices are based at the European Centre on the plateau du Kirchberg. The Council has also met occasionally in Strasbourg , in various other cities, and also outside the Union: for example in 1974 when it met in Tokyo and Washington, D. C. while trade and energy talks were taking place. Under

1156-414: The avis facultatif maxim was: "The Commission proposes, and the Council disposes"; but now the vast majority of laws are subject to the ordinary legislative procedure , which works on the principle that consent from both the Council and Parliament are required before a law may be adopted. Under this procedure, the Commission presents a proposal to Parliament and the Council. Following its first reading

1224-497: The 180-metre-high (590 ft) dry cooling tower, which at one time was the highest cooling tower in the world, was explosively dismantled and from October 22, 1993 to April 1995 the remaining fuel was unloaded and transported to the intermediate storage in Ahaus . The remaining facility was "safely enclosed". Dismantling is not expected to start before 2027. From 2013 to 2017, 23 Million Euro were budgeted for lighting, safeguarding and

1292-633: The 1970s, Nukem has transitioned from playing a modest role in uranium brokerage to becoming one of the world's largest intermediaries in the international nuclear fuel market. Nukem was established in 1960 by Degussa , Rio Tinto and Mallinckrodt . In 1965, RWE acquired 25% of shares. Effective April 1, 2006, the private equity firm Advent International has taken over Nukem. In 2007, Nukem sold its subsidiaries NUKEM Ltd. to Freyssinet SAS , NUKEM Corp. to EnergySolutions , NIS Ingenieure and Assistance Nucleaire S.A. to Siempelkamp. On 14 December 2009, Nukem sold its subsidiary Nukem Technologies, which

1360-775: The Authority's domain, and the Council's consent was only required on decisions outside coal and steel. As a whole, the Council only scrutinised the High Authority (the executive). In 1957, the Treaties of Rome established two new communities, and with them two new Councils: the Council of the European Atomic Energy Community (EAEC) and the Council of the European Economic Community (EEC). However, due to objections over

1428-645: The Council moved into the Justus Lipsius building , across the road from Charlemagne. However, its staff was still increasing, so it continued to rent the Frère Orban building to house the Finnish and Swedish language divisions. Staff continued to increase and the Council rented, in addition to owning Justus Lipsius, the Kortenberg, Froissart, Espace Rolin, and Woluwe Heights buildings. Since acquiring

1496-629: The Council of the European Union . The Secretariat is divided into eleven directorates-general , each administered by a director-general . The Council first appeared in the European Coal and Steel Community (ECSC) as the "Special Council of Ministers", set up to counterbalance the High Authority (the supranational executive, now the Commission). The original Council had limited powers: issues relating only to coal and steel were in

1564-511: The Council still does not approve the Parliament's position, then the text is taken to a " Conciliation Committee " composed of the Council members plus an equal number of MEPs. If a Committee manages to adopt a joint text, it then has to be approved in a third reading by both the Council and Parliament or the proposal is abandoned. The few other areas that operate the special legislative procedures are justice & home affairs, budget and taxation and certain aspects of other policy areas: such as

1632-604: The Council will always be the member from the state holding the Presidency. A delegate from the following Presidency also assists the presiding member and may take over work if requested. The exception however is the foreign affairs council, which has been chaired by the High Representative since the entry into force of the Lisbon Treaty . The role of the Presidency is administrative and political. On

1700-424: The Council's present rules of procedures the Council can, in extraordinary circumstances, hold one of its meetings outside Brussels and Luxembourg. From 2017, both the Council of the European Union and the European Council adopted the purpose-built Europa building as their official headquarters, although they continue to utilise the facilities afforded by the adjacent Justus Lipsius building . The focal point of

1768-462: The Council's wishes. This has in some cases led to clashes between both bodies with the Council's system of intergovernmentalism contradicting the developing parliamentary system and supranational principles. The primary purpose of the Council is to act as one of two vetoing bodies of the EU's legislative branch , the other being the European Parliament . Together they serve to amend, approve or disapprove

1836-666: The ECSC Council held its Luxembourg City meetings in the Cercle Municipal on Place d'Armes . Its secretariat moved on numerous occasions but between 1955 and 1967 it was housed in the Verlorenkost district of the city. In 1957, with the creation of two new Communities with their own Councils, discretion on location was given to the current Presidency. In practice this was to be in the Château of Val-Duchesse until

1904-479: The EU population. A 'blocking minority' can only be formed by at least 4 member states, even if the objecting states constitute more than 35% of the population. Council resolutions have no legal effect. Usually the Council's intention is to set out future work foreseen in a specific policy area or to invite action by the Commission. If a resolution covers a policy area which is not entirely within an area of EU competency,

1972-551: The EU which it conferred upon the European Commission . It is considered by some to be equivalent to an upper house of the EU legislature, although it is not described as such in the treaties. The Council represents the executive governments of the EU's member states and is based in the Europa building in Brussels. The Council also has an important role in the formation of the European Commission. The Council sitting in

2040-505: The EU's population. Almost all members of the Council are members of a political party at national level, and most of these are members of a European-level political party . However the Council is composed to represent the Member States rather than political parties and the nature of coalition governments in a number of states means that party breakdown at different configuration of the Council vary depending on which domestic party

2108-515: The Parliament and Commission had been strengthened inside the Community pillar , curtailing the ability of the Council to act independently. The Treaty of Lisbon abolished the pillar system and gave further powers to Parliament. It also merged the Council's High Representative with the Commission's foreign policy head , with this new figure chairing the foreign affairs Council rather than

2176-457: The Parliament may propose amendments. If the Council accepts these amendments then the legislation is approved. If it does not then it adopts a "common position" and submits that new version to the Parliament. At its second reading, if the Parliament approves the text or does not act, the text is adopted, otherwise the Parliament may propose further amendments to the Council's proposal. It may be rejected out right by an absolute majority of MEPs. If

2244-501: The Presidency substantial influence in the work of the Council during its term. The Presidency also plays a major role in representing the Council within the EU and representing the EU internationally, for example at the United Nations. Legally speaking, the Council is a single entity (this means that technically any Council configuration can adopt decisions that fall within the remit of any other Council configuration) but it

2312-651: The Ravenstein building of Brussels. In 1971 the Council and its secretariat moved into the Charlemagne building , next to the Commission's Berlaymont , but the Council rapidly ran out of space and administrative branch of the Secretariat moved to a building at 76 Rue Joseph II/Jozef II-straat and during the 1980s the language divisions moved out into the Nerviens, Frère Orban, and Guimard buildings. In 1995,

This includes summoning the Council for meetings along with directing the work of COREPER and other committees and working parties . The political element is the role of successfully dealing with issues and mediating in the Council. In particular this includes setting the agenda of the council, hence giving

2448-506: The atomic legal authorizing agency to feed electricity to the grid until November 16, 1985. It operated at full power in February 1987 and was shut down September 1, 1989, after operating for less than 16,000 hours. Because the operator did not expect the decision to decommission the facility, the plant was put into "safe enclosure" status, given that this was the only technical solution for fast decommissioning, especially in consideration of

2516-469: The autumn of 1958, at which point it moved to 2 Rue Ravensteinstraat in Brussels. The 1965 agreement (finalised by the Edinburgh agreement and annexed to the treaties) on the location of the newly merged institutions, the Council was to be in Brussels but would meet in Luxembourg City during April, June, and October. The ECSC secretariat moved from Luxembourg City to the merged body Council secretariat in

2584-660: The body's meetings. Ecofin 's Eurozone component, the Euro group , is also a formal group with its own President. Its European Council counterpart is the Euro summit formalized in 2011 and the TSCG . Following the entry into force of a framework agreement between the EU and ESA there is a Space Council configuration—a joint and concomitant meeting of the EU Council and of the ESA Council at ministerial level dealing with

2652-459: The council is composed of ministers from each state government who are responsible for this area: the agriculture and fisheries ministers. The chair of this council is held by the member from the state holding the presidency (see section above). Similarly, the Economic and Financial Affairs Council is composed of national finance ministers, and they are still one per state and the chair is held by

2720-503: The effects of the incident were assessed. Later analysis showed that the plant had released radioactive aerosols, estimated at up to 2 · 10 Bq, likely slightly below 180-day operation limits of 1,85 · 10 Bq, yet possibly above daily limits of 0,74 · 10 Bq. The exact amount of released material could never be determined. Control room operators, when confronted with radiation alarms, disabled aerosol measuring equipment and failed to change filters that would have allowed for exact measurements of

2788-489: The fiscal aspects of environmental policy. In these areas, the Council or Parliament decide law alone. The procedure used also depends upon which type of institutional act is being used. The strongest act is a regulation , an act or law which is directly applicable in its entirety. Then there are directives which bind members to certain goals which they must achieve, but they do this through their own laws and hence have room to manoeuvre in deciding upon them. A decision

The Foreign Affairs Council shall elaborate the Union's external action on the basis of strategic guidelines laid down by the European Council and ensure that the Union's action is consistent. Each council configuration deals with a different functional area, for example agriculture and fisheries. In this formation,

2924-467: The helium circuit. The electric conversion system produced 308 megawatts of electricity. The waste heat from the THTR-300 was exhausted using a dry cooling tower . On May 4, 1986, fuel pebbles became lodged in the fuel feeding system due to handling errors by the control room operator, specifically the manual override of the automated fuel loading mechanism, a deviation from standard operating procedures. Consequently, radioactive helium containing aerosols

2992-646: The impasse was resolved the following year by the Luxembourg compromise . Although initiated by a gamble of the President of the Commission, Walter Hallstein , who later on lost the Presidency, the crisis exposed flaws in the Council's workings. Under the Merger Treaty of 1967, the ECSC's Special Council of Ministers and the Council of the EAEC (together with their other independent institutions) were merged into

3060-486: The implementation of the ESP adopted by both organisations. The General Secretariat of the Council provides the continuous infrastructure of the Council, carrying out preparation for meetings, draft reports, translation, records, documents, agendas and assisting the presidency. The Secretary General of the Council is head of the Secretariat. The Secretariat is divided into eleven directorates-general, each administered by

3128-536: The incident from regulatory authorities, then denied any irregularities, claiming that any emissions were within permissible limits and were part of normal operations. They attributed the detected radioactivity to routine discharges or to the existing contamination from Chernobyl. Official investigations were delayed, and environmental monitoring stations eventually identified unusual levels of radioactive Protactinium-233 (²³³Pa) isotopes, inconsistent with fallout from Chernobyl. The plant had to be ordered to shut down while

3196-434: The lack of a final storage facility. The THTR-300 was a helium -cooled high-temperature reactor with a pebble bed core consisting of approximately 670,000 spherical fuel compacts each 6 centimetres (2.4 in) in diameter with particles of uranium-235 and thorium-232 fuel embedded in a graphite matrix. The pressure vessel that contained the pebbles was prestressed concrete . The THTR-300's power conversion system

3264-714: The legislative acts. Under the CFSP they consist of "common positions", "joint actions", and "common strategies". Common positions relate to defining a European foreign policy towards a particular third-country such as the promotion of human rights and democracy in Myanmar , a region such as the stabilisation efforts in the African Great Lakes , or a certain issue such as support for the International Criminal Court . A common position, once agreed,

3332-543: The member coming from the presiding country. The Councils meet irregularly throughout the year except for the three major configurations (top three below) which meet once a month. As of 2020 , there are ten formations: Complementing these, the Political and Security Committee (PSC) brings together ambassadors to monitor international situations and define policies within the CSDP, particularly in crises. The European Council

3536-455: The position of their Member State's executive , be they ambassadors, ministers or heads of state/government. The Council meets in 10 different configurations of 27 national ministers (one per state ). The precise membership of these configurations varies according to the topic under consideration; for example, when discussing agricultural policy the Council is formed by the 27 national ministers whose portfolio includes this policy area (with

3604-418: The proposals of the European Commission , which has the sole power to propose laws. Jointly with the Parliament, the Council holds the budgetary power of the Union and has greater control than the Parliament over the more intergovernmental areas of the EU, such as foreign policy and macroeconomic co-ordination. Finally, before the entry into force of the Treaty of Lisbon, it formally held the executive power of

3672-400: The provisions necessary for its organisation and functioning. The Presidency of the Council is not a single post, but is held by a member state's government. Every six months the presidency rotates among the states, in an order predefined by the Council's members, allowing each state to preside over the body. From 2007, every three member states co-operate for their combined eighteen months on

3740-481: The reactor experienced difficulties with fuel elements breaking more often than anticipated. The presumptive cause of the fuel element damage was the frequent and overly-deep insertion of control rods during the commissioning process. The Nukem fuel factory in Hanau was decommissioned in 1988 for security reasons, endangering the fuel fabrication chain. It was decided on September 1, 1989 to shut down THTR-300, which

3808-570: The related European Commissioners contributing but not voting). The Presidency of the Council rotates every six months among the governments of EU member states, with the relevant ministers of the respective country holding the Presidency at any given time ensuring the smooth running of the meetings and setting the daily agenda. The continuity between presidencies is provided by an arrangement under which three successive presidencies, known as Presidency trios , share common political programmes. The Foreign Affairs Council (national foreign ministers)

3876-440: The release, again deviating from procedures. Repeated false and misleading statements by the operator quickly eroded trust of state and federal officials, as well as the public. The backdrop of the ongoing Chernobyl crisis, where the accident was concealed, too, further undermined public perception of Germany's nuclear power plants, contributing to growing negative sentiments about nuclear energy in Germany. Beginning in late 1985,

3944-485: The required availability of 70% (1988: 41 %). On September 1, 1989, the THTR-300 was deactivated due to cost and the anti nuclear sentiments after Chernobyl. In August 1989, the THTR company was almost bankrupted after a long period of shut down due to broken components in the hot gas duct. The German government bailed the company out with 92 million Mark . THTR-300 was in full service for 423 days. On October 10, 1991,

4012-626: The resolution will be issued as a "resolution of the Council and the representatives of the governments of the member states". Examples are the Council Resolution of 26 September 1989 on the development of subcontracting in the Community and the Council Resolution of 26 November 2001 on consumer credit and indebtedness. The legal instruments used by the Council for the Common Foreign and Security Policy are different from

4080-416: The room during the Council vote on Ukraine-EU accession talks, this ensuring that the Council passed that issue without veto. The legislative branch officially holds the Union's budgetary authority. The EU's budget (which is around 155 billion euro ) is subject to a form of the ordinary legislative procedure with a single reading giving Parliament power over the entire budget (prior to 2009, its influence

4148-441: The rotating presidency. The European Council was declared a separate institution from the Council, also chaired by a permanent president, and the different Council configurations were mentioned in the treaties for the first time. The development of the Council has been characterised by the rise in power of the Parliament, with which the Council has had to share its legislative powers. The Parliament has often provided opposition to

By 1990, a group of firms planned to proceed with the construction of an HTR-500 , a successor of the THTR-300 with an up-rated thermal output of 1390 megawatts and electrical output of 550 megawatts. No new nuclear power plant was ever commissioned, however, as

4284-403: The supranational power of the Authority, their Councils had more powers; the new executive bodies were known as "Commissions". In 1965, the Council was hit by the "empty chair crisis". Due to disagreements between French President Charles de Gaulle and the Commission's agriculture proposals, among other things, France boycotted all meetings of the Council. This halted the Council's work until

4352-747: Was assigned the portfolio. However, the broad ideological alignment of the government in each state does influence the nature of the law the Council produces and the extent to which the link between domestic parties puts pressure on the members in the European Parliament to vote a certain way. By a decision of the European Council at Edinburgh in December 1992, the Council has its seat in Brussels but in April, June, and October, it holds its meetings in Luxembourg City .

But if the joint conciliation text is not approved, the Parliament may adopt the budget definitively. In addition to the budget, the Council coordinates the economic policy of members. The Council's rules of procedure contain

4488-552: Was released to the environment via the feed system's exhaust air chimney. The incident initially went unnoticed due to the overlap with radioactive fallout from the Chernobyl disaster , complicating attribution. An anonymous informant from the THTR-300 workforce was the first to blow the whistle on the incident, and alleged that there was a deliberate attempt to conceal the radioactive emissions from authorities and environmental groups. The reactor operators had up to this point concealed

4556-416: Was similar to the Fort St. Vrain reactor in the USA, in that the reactor coolant transferred the reactor core's heat to water. The thermal output of the core was 750 megawatts ; heat was transferred to the helium coolant, which then transported its heat to water, which then was used to generate electricity via a Rankine cycle . Because this system used a Rankine cycle, water could occasionally ingress into

4624-403: Was submitted to the supervisory authority by the HKG on September 26, 1989 in accordance with the Atomic Energy Act. In the short operational life span of THTR-300 from 1985 to 1989, with only 423 full-load operating day equivalents, 80 incidents were logged. The nuclear power plant was plagued with shutdowns due to design issues, generating only 2891 GWh, far less than anticipated, never reaching
