(1) When radioactivity level is greater than 10 percenc 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 DCi/mi 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

.- of gamma isotopic analysis of the primary coolant, including dissolved gaseous activities, radiochemical 1EE analysis for Sr-89 and Sr-90, and tritium analysis.

(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 time for movement downstream in order to verify diuttion, or monthly for continuous discharge.

(4) When animals are on pasture.

(5) Milk samples will be composited weekly for monthly analysis.

(6) When fish samples are available.

ANALYTICAL SENSITIVITIES The sensitivity of the analyses for various radionuclides in representative samples is typically as follows:

Airborne Particulate Water Fish Milk Vegetation Soil or Gag Analysis (pCi/1) (pCi/m ) (pCi/kg, wet) (pC1/l) (pCi/kg, wet) (pCi/kg, dry).

i The sensitivity of the radiation exposure measurements (gross gamma) is approximately 10mR for a three-month integrated exposure and .005mR/hr for exposure rate measurement.

(1) These sensitivities may vary depending on the water content of the vegetation samples.
