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.
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.
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 ...
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.
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.
Belgium's energy production is plunging as its nuclear reactors are taken offline for repairs, with the power shortfall this winter seen as a test of the country's ability to cope when the ...
Beyond-design-basis events can reduce or eliminate the margin of safety of the structures, systems and components, possibly resulting in a catastrophic failure. [8]The Fukushima Daiichi nuclear disaster was caused by a "beyond-design-basis event": the tsunami and associated earthquakes were more powerful than the plant was designed to accommodate.
Rising concern over the impact of a potential Russian gas cutoff is fueling the debate in Germany over whether the country should switch off its last three nuclear power plants as planned at the ...
