TABLE 7.2-1 (Continued)
ACTION STATEMENTS ACTION 1: With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirements, effluent releases may continue provided that best efforts are made to repair the instrument and that prior to initiating a release:
1.
At least two independent samples of the tank to be discharged are analyzed in accordance with Specification 8.1.1.1.1, and; 2.
The original release rate calculations and discharge valving are independently verified by a second individual.
ACTION 2: With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided that best efforts are made to repair the instrument gamma) at a lower limit of detection of at least 3 x 10'yity (beta or and that grab samples are analyzed for gross radioactl

Once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the specific activity of the secondary coolant is less than or equal to 0.01 pCi/gm DOSE EQUIVALENT I-131.
ACTION 3: With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, service water discharge via this l
pathway may continue provided that best efforts are made to repair the instrument and that once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> grab samples of the service water effluent are collected and analyzed for gross radioactivit (beta or gamma) at a lower limit of detection of at least 3 x 10'y
- Ci/ml.
ACTION 4: With the namber of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided that best efforts are made to repair the instrument and that the flow rate is estimated once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> during actual releases.
Pump performance curves generated insitu may be used to estimate flow.
