(1) When radioactivity level is greater than 10 percent of the limits of Specification 3.1.4, the sampling frequency shall be increased to a minimum of once each day.
(2)
E determination will be started when gross beta-gamma activity analysis indicates greater than 10 uCi/ml and will be redetermined for each 10 pCi/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 coolant with half lives greater than 30 minutes. This is expected to consist CD of gamma isotopic analysis of the primary coolant, including dissolved gaseous activities, radiochemical bd analysis for Sr-89 and Sr-90, and tritium analysis.

NOTES: (2) Record status of waste discharge operations at time of sampling for surface water samples.
(3) Surface water samples are to be collected closely following liquid discharge to allow for sufficient i

1 The sensitivity of the radiation exposure measurements (gross gamma) is approximately 10mk for a three-month integrated exposure and.005mR/hr for exposure rate measurement.
These sensitivities may vary depending on the water content of the vegetation samples.
