ActiveInitial criticality tests for pressurized water reactor of nuclear power plants
压水堆核电厂反应堆首次临界试验
Application Summary AI generated
This standard specifies the procedures, requirements, and acceptance criteria for conducting the initial criticality tests on pressurized water reactors (PWRs) in nuclear power plants. It is applied during the commissioning phase of a new PWR unit, ensuring that the reactor core achieves a controlled, self-sustaining chain reaction for the first time while verifying safety parameters and operational limits. The standard is used by nuclear plant operators, regulators, and testing engineers to validate reactor physics characteristics before full-power operation.
