A clean-up crew working to remove radioactive contamination after the Three Mile Island accident. Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards".
George Galatis was a senior nuclear engineer who reported safety problems at the Millstone 1 Nuclear Power Plant, relating to reactor refueling procedures, in 1995. [ 36 ] [ 37 ] Other nuclear whistleblowers include Arnold Gundersen , David Lochbaum , and Karen Silkwood .
Under normal conditions, nuclear power plants receive power from generator. However, during an accident a plant may lose access to this power supply and thus may be required to generate its own power to supply its emergency systems. These electrical systems usually consist of diesel generators and batteries.
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 ...
(a) The Secretary, in cooperation with the Nuclear Regulatory Commission, shall initiate a study as to the sufficiency of efforts in the United States to provide specially trained professionals to operate the controls of nuclear power plants and other facilities in the back-end of the nuclear fuel cycle. In carrying out the study, the Secretary ...
Passive nuclear safety is a design approach for safety features, implemented in a nuclear reactor, that does not require any active intervention on the part of the operator or electrical/electronic feedback in order to bring the reactor to a safe shutdown state, in the event of a particular type of emergency (usually overheating resulting from a loss of coolant or loss of coolant flow).
The Convention on Nuclear Safety is a 1994 International Atomic Energy Agency (IAEA) treaty that governs safety rules at nuclear power plants in state parties to the convention. The convention creates obligations on state parties to implement certain safety rules and standards at all civil facilities related to nuclear energy. These include ...
If nuclear power use is to expand significantly, nuclear facilities will have to be made extremely safe from attacks that could release massive quantities of radioactivity into the community. New reactor designs have features of passive safety , such as the flooding of the reactor core without active intervention by reactor operators.
