61-403: The plant produces 1,279 electrical megawatts (MWe) of net power. As of 2019, Callaway has completed five "breaker-to-breaker" runs — operating from one refueling to the next without ever being out of service. It is one of only 26 U.S. reactors to achieve such a feat according to Ameren . On November 19, 2005, its workers finished replacing all four steam generators in 63 days, 13 hours,

122-571: A 1,600-MW Areva Evolutionary Power Reactor . Ameren sought to construct this second reactor in order to meet their projected increase in demand for electricity over the next decade. In April 2009, the proposal was cancelled. One stumbling block was a law that forbids utilities to charge customers for the interest accrued on a construction loan before a new plant produces electricity. The new nuclear reactor would have cost at least $ 6 billion. In April 2012, Ameren Missouri and Westinghouse Electric Company announced their intent to seek federal funding for

183-516: A CEO include Ford , HSBC , Alphabet Inc. , and HP . A vice- or deputy chair, subordinate to the chair, is sometimes chosen to assist and to serve as chair in the latter's absence, or when a motion involving the chair is being discussed. In the absence of the chair and vice-chair, groups sometimes elect a chair pro tempore to fill the role for a single meeting. In some organizations that have both titles, deputy chair ranks higher than vice-chair, as there are often multiple vice-chairs but only

Cities within 50 miles include Fulton (11 miles to city center), Jefferson City (26 miles to city center), and Columbia (32 miles to city center). In August 2010, the Nuclear Regulatory Commission's estimated that the annual chance that an earthquake might damage

Ameren instead decided to close the plant in 2024, 15 years ahead of schedule. Sippel also ordered Ameren to install sulfur dioxide scrubbers on its Labadie plant, also in Missouri, but a federal appeals court overturned that condition even though “the government never provided notice of or alleged” that

366-479: A major pooled energy power distributor with its future Ameren mate, Union Electric Company. The arrangement formed the Midwest Power Pool system. The CIPS Meredosia, Illinois Power Station became a key contributor to the pool, which also included the later Ameren subsidiary Illinois Power Company . In 1963 Union Electric completed construction of one of the largest pumped storage plants at that time,

427-414: A month after Ameren had announced plans to build solar energy plants in Missouri, all plans to expand nuclear-powered electricity generation at the site were scrapped. The cooling tower at Callaway is 553 feet (169 m) tall. It is 430 feet wide at the base, and is constructed from reinforced concrete. It cools about 585,000 US gallons (2,210,000 L; 487,000 imp gal) of water per minute when

488-519: A new generation of nuclear reactors to be installed at the Callaway site. The U.S. Department of Energy could provide up to $ 452 million in research and development funds to Westinghouse. The new reactors would be smaller and, the companies claimed, safer in design than any currently operating. Ameren Missouri was to apply to license up five of the 225-megawatt reactors at the Callaway site, more than doubling its current electrical output. In August 2015,

549-416: A plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination ; and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.

On the same date, AmerenUE changed its name to Ameren Missouri Company. The former Illinois portion of

793-568: A world record for a four-loop plant. In 2014, the Nuclear Regulatory Commission tests found contaminated ground water near the site. The plant experienced three unplanned shutdowns in 2020. On December 24, 2020, an electric fault on the non-safety main generator caused an extensive outage requiring the replacement of significant components. The components were replaced, inspected, and tested during subsequent months. According to NRC inspection reports, on August 2, 2021,

There is a growing push by public market investors for companies with an executive chair to have a lead independent director to provide some element of an independent perspective.

Consequently, FERC fined Ameren $ 15 million. The State of Missouri has sued Ameren for actual and punitive damages, alleging Ameren recklessly operated the plant and put financial considerations from sale of power to other companies over safety, maintenance and engineering. The plant

1220-575: The 1980s, and paid dividends since 1947. As of the late 1980s, the company generated electricity and natural gas, almost entirely from coal plants, with less than 1% fueled from oil and gas. By then, with about $ 360 million in assets, it carried long-term debt of over US$ 2 billion. In 1991, Illinois Power reorganized as a holding company, Illinova Corporation, which traded on the NYSE with ticker symbol ILN. Illinova had grown to an S&P Midcap 400 stock by 1996, with over US$ 415 million in assets, and had brought

( NYSE :  DYN ), in which Chevron Corporation also took a 28% stake. Dynegy in turn had been created in June 1998, from the merger of Chevron's natural gas and natural gas liquids businesses with Dynegy's predecessor, NGC Corp. (former ticker NGL). NGC had been an integrated natural gas services company around since 1994. Following Ameren's acquisition of Illinois Power, that subsidiary began doing business as AmerenIP . The IP acquisition made Ameren

Unlike most coal energy plants, the Labadie coal plant in Franklin County, Missouri , does not have sulfur dioxide scrubbers, making it the country's highest emitter of the pollutant, according to a St. Louis Post-Dispatch report. Even if Labadie’s SO2 emissions were cut in half, it would still emit more than all but two coal plants in
