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.
In most countries majority of citizens supported operations of existing nuclear power plants but opinions were divided on construction of new ones, with minority calling for shut down of existing power plants. Across all countries, 38% were in support of expansion of nuclear power and 47% opposed. [10]
The power station at Dodewaard was shut down in 1997. In 1997 the government decided to end Borssele's operating licence, at the end of 2003. In 2003 the shut-down was postponed by the government to 2013. [98] [99] In 2005 the decision was reversed and research in expanding nuclear power has been initiated.
Here is a look at Germany's politically charged debate on nuclear power. The move marks another hiccup in the country's long-running plan to end the use of atomic energy.
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 ...
A reactor protection system (RPS) is a set of nuclear safety and security components in a nuclear power plant designed to safely shut down the reactor and prevent the release of radioactive materials. The system can "trip" automatically (initiating a scram), or it can be tripped by the operators. Trips occur when the parameters meet or exceed ...
SCRAM button at the Experimental Breeder Reactor I in Idaho. Sometimes the switch will have a flip cover to prevent inadvertent operation. A scram or SCRAM is an emergency shutdown of a nuclear reactor effected by immediately terminating the fission reaction.
The anti-nuclear movement is a social movement that opposes various nuclear technologies.Some direct action groups, environmental movements, and professional organisations have identified themselves with the movement at the local, national, or international level.
