RADIOACTIVE LIQUID EFFLtENT MONITORING INSTRtRENTATION .

Table Notes 8 - At all times - which means that channels shall be OPERABLE and in service on a continuous, uninterrupted basis, except that outages are permitted, for a maximum of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, for the purpose or maintenance and performance or required tests, checks, calibrations, or sampling. ,

" - ugh both monitors are normally operable, only one is necessary as the activity measured by each j can be related to the other, and both monitors are capable of automatically isolating the steam Qnerationblowdown.

      • - Modes 1-5 and Mode 6 when pathway is being used except that outages are permitted for a maximum or 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for the purpose of maintenance and performnce or required tests, checks, etlibrations, or sampling. l f - Since the only source or service water contamination is the reactor building closed cooling water, monitoring of the closed cooling water and conservative leakage assumptions will provide adequate -

control or service water effluents.

ff - The dilution water is determined by the use of condenser cooling water and service water pump status.

Only those pumps actually discharging to the quarry at the time or release are included. Pump status is only reviewed for purposes or determining rious, fif - Determined by the use or valve curves and/or make up flow rates for the purpose or determining flows only.
