1 Scope
This standard specifies the determination methods of primary coolant, steam generator boiler water and radionuclide specific activity in steam and the determination methods of liquid effluent and gaseous effluent source terms.
The calculated source term of this standard is applicable to assess the annual mean emission of radionuclide released to environment through liquid and gaseous effluents.
The adopted data of this standard is based on the pressurized-water reactor nuclear power plant using zirconium cladding uranium dioxide fuel.
This standard is only applicable to the pressurized-water reactor nuclear power plant adopting U-pipe steam generator.
