E determination will be started when ernss beta-gamma activity analysis indicates greater than 10 uCi/ml (2) and will be redetermined for each 10 nCi/ml increase in gross beta-gamma activity analysis thereafter.
A.
radiochemical analysis for this purpose shall consist of a quantitative measurement of 95 percent of the radionuclides in the reactor c.colant with half lives greater than 30 minutes. This is expected to consist of gamma isotopic analysis of the primary coolant, including dissolved gaseous activities, radiochemical analysis for Sr-89 and Sr-90, and tritium analysis.
