A reactor protection system is designed to immediately terminate the nuclear reaction. By breaking the nuclear chain reaction, the source of heat is eliminated. Other systems can then be used to remove decay heat from the core. All nuclear plants have some form of reactor protection system.
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 ...
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in the reactor entering an unsafe operating condition.
When pressure control is lost in a reactor plant, depending on the level of heat being generated by the reactor plant, the heat being removed by the steam or other auxiliary systems, the initial pressure, and the normal operating temperature of the plant, it could take minutes or even hours for operators to see significant trends in core behaviour.
The U.S. Nuclear Regulatory Commission is issuing a construction permit for a new type of nuclear reactor that uses molten salt to cool the reactor core. The NRC is issuing the permit to Kairos ...
In the field of nuclear projects, the company specializes in the design and construction of nuclear research reactors, radioisotope production plants, nuclear fuel manufacturing plants, uranium enrichment facilities, neutron beam transport systems, radiation protection instrumentation, reactor protection systems, and modernization and refurbishment of research reactors.
The regulation imposes significant costs on all nuclear energy developers, especially startups like Last Energy, which builds 20-megawatt (MW) micro nuclear reactors that are inherently safe and ...
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).
