Application Summary AI generated

This standard specifies the analytical methods and requirements for determining the radiation source term from the reactor core and spent fuel assemblies in pressurized water reactor (PWR) nuclear power plants. It is applied during the design, operation, and decommissioning phases to calculate radiation levels for shielding design, worker dose assessment, and radioactive waste management. The standard ensures consistency in source term analysis across Chinese PWR facilities, supporting safety evaluations and regulatory compliance.
