ms and principal components, including provisions for obtaining samples from at least the points indicated below. The guidelines of regulatory position C.2 in Regulatory Guide 1.21 (refer- ence 1) and regulatory positions C.1 and C.4.a in Regulatory Guide 1.56 (reference 2) are used to meet the requirements of the relevant General Design Criteria (GOC). GDC a. For a pressurized water reactor (PWR): Reactor coolant (e.g., letdown system, etc.) Refueling (borated) water storage tank. ECCS core flooding tank. Boric acid mix tank. Boron injection tank. Chemical additive tank. Spent fuel pool. Secondary coolant (e.g., condensate hotwell) Pressurizer tank. Steam generator blowdown (if applicable). Secondary coolant condensate treatment waste Sumps inside containment. Containment atmosphere. Gaseous radwaste storage tanks. 13, 14, 26, 64 13, 26 13 13, 26 13 13, 14, 41 63 13, 14 64 14, 64 64 64 64 63, 64 9.3.2-3 Rev. 2 - July 1981 b. For a boiling water reactor (BWR): Main condenser evacuation system offgas. Reactor coolant (inlet and outlet of reactor water cleanup system). Standby liquid control system tank. Sumps inside containment. Spent fuel pool. Drywell atmosphere (Mark I & II). Inlet and outlet of gaseous radwaste storage tank. Inlet and outlet of condensate polishing system. Other sample points that may be included in the PSS remote sampling are given in SRP Section 11.5. 64 13, 14, 64 13, 26 64 63 64 63, 64 13, 14 but do not require 2. The required analysis and frequencies should be given in the plant tech- nical specifications. 3. CMEB will use the following guidelines for determining the acceptability of the PSS functional design: a. Provisions should be made to assure representative samples from liquid process streams and tanks. For tanks, provisions should be made to sample the bulk volume of the tank and to avoid sampling from low points or from potential sediment traps. For process stream samples, sample points should be located in turbulent flow zones. The
