reactor coolant, the ECCS core flooding tank, the refueling water storage tank, the boric acid mix tank, and the boron injection tank for boron concentrations; (2) the requirements of GDC 13 and 14 in Appendix A to 10 CFR Part 50 , to monitor variables that can affect the reactor coolant pressure boundary and 72 to assure a low probability of abnormal leakage, rapidly propagating failure, and gross rupture, respectively, by sampling the reactor coolant and the secondary coolant for chemical impurities that can affect the reactor coolant pressure boundary; (3) the requirements of GDC 26 in Appendix A to 10 CFR Part 50 to control the rate of 73 reactivity changes, by sampling the reactor coolant, the refueling water storage tank, and the boric acid mix tank for boron concentration; (4) the requirements of GDC 13, 14, and 41 in Appendix A to 10 CFR Part 50 to monitor variables that can affect the integrity of 74 the reactor core and reactor coolant pressure boundary and to reduce the concentration and quality of fission products released to the environment following postulated accidents, respectively, by sampling the chemical additive tank for chemical additive concentrations, to ensure an adequate supply of chemical for meeting the material compatibility requirements and the elemental iodine removal requirements of the containment spray and recirculation solutions following a postulated accident; and (5) the requirements of GDC 64 in Appendix A to 10 CFR Part 50 to monitor for radioactivity 75 that may be released from normal operations, including anticipated operational occurrences, and from postulated accidents, by sampling the reactor coolant, the pressurizer tank, the steam generator blowdown, the secondary coolant condensate treatment waste, the sump inside containment, the containment atmosphere, and the gaseous radwaste storage tank for radioactivity. For BWR The staff has determined that the proposed process sampling system meets (1) the requirements of GDC 13
