Shutdown is the state of a nuclear reactor when the fission reaction is slowed significantly or halted completely. Different nuclear reactor designs have different definitions for what "shutdown" means, but it typically means that the reactor is not producing a measurable amount of electricity or heat and is in a stable condition with very low reactivity.
This table lists all currently operational power stations. Some of these may have reactors under construction, but only current net capacity is listed. Capacity of permanently shut-down reactors is not included, but capacity of long-term shut-down reactors (today mainly in Japan) is included.
The nuclear reactors at the Barsebäck Nuclear Power Plant were shut down between 1999 and 2005. In October 2015, corporations running the nuclear plants decided to phase out two reactors at Oskarshamn [92] and two at Ringhals, [93] reducing the number of remaining reactors from 12 in 1999 to 6 in 2020.
A 2017 nuclear construction fiasco seemingly ended hope that two reactors would be built in South Carolina. Could the project be restarted? Years after nuclear fiasco soaked ratepayers, leaders ...
The late 1960s and early 1970s saw a rapid growth in the development of nuclear power in the United States. By 1976, however, many nuclear plant proposals were no longer viable due to a slower rate of growth in electricity demand, significant cost and time overruns, and more complex regulatory requirements.
Workers simulated the shutdown on Tuesday of the Pilgrim Nuclear Power Station, just days before the plant will stop producing energy after 47 years of operation. On Friday, a team of workers will ...
On December 21, 2009 the Unit 3 reactor tripped and shut down for longer than 72 hours. [28] On July 27, 2009, the Unit 2 reactor tripped and shut down for longer than 72 hours. On August 9, 2013, the Unit 3 reactor tripped and shut down due to a malfunction. In 2016, unit 3 was shut down following a hydrogen gas leak. [29]
The groups say PG&E has delayed testing on equipment that could “cause a catastrophic meltdown” of Diablo Canyon nuclear power plant. Anti-nuclear groups demand ‘immediate shutdown’ of ...
