ment systems, ETSB compares parameters and calculations given in the SAR with the models and parameters given in NUREG-0016 and NUREG-0017. If the SAR includes models or parameters to estimate reactor coolant concentrations and leakage rates that differ from these reports, the parameters and calculations used need to be-substantiated. The preferred method of substantiation is by presentation of operating data from similar reactors. 2. ETSB performs an independent calculation of the primary and secondary (PWR) coolant concentrations and of the release rates of radioactive materials using the GALE Computer Code, and the "Principal Parameters for Source Term Calculations" given in NUREG-0016 and NUREG-0017, and the information supplied by the applicant in accordance with Appendices A and B of Regulatory Guide 1.112. 3. In the calculation, ETSB will use the applicant's values as given in the SAR for the following parameters: design core thermal power level, steam flow rate, coolant mass, and coolant purification rates. 4. ETSB will use the coolant concentrations, leakage rates, and effluent release rates calculated above as inputs for evaluation of the liquid -waste system, under SRP Section 11.2, and the gaseous waste systems, under SRP Section 11.3, to determine if these systems meet the dose design objectives of Appendix I to 10 CFR Part 50. 5. The ETSB will review under SRP Section 11.5 "Process and Effluent Radio- logical Monitoring and Sampling Systems," the monitoring and control provisions for all the applicable effluent release points identified in subsection I.1, above. 6. The ETSB source term calculations are used for both the review of the SAR and for the staff's Environmental Impact Statement. IV. EVALUATION FINDINGS Sufficient information has been provided by the applicant so that the require- ments of 10 CFR Part 50, Sections 50.34 and 50.34a have been met. The ETSB summary statement on the acceptability of source terms used as design parameters for the
