TABLE NOTATION -

ACTION 100 -

With the number of OPERABLE channels less than required by the Minimum Channels OPERABLE requirement, effluent releases may continue for up to 14 days provided that i, prior to initiating a release:

1

a. At least two independent samples are analyzed in accordance with Specification 4.11.1.1.3, and j

b. At least two technically qualified members of the i

Facility Staff independently verify the release rate

calculations and discharge line valving; i

Otherwise, suspend release of radioactive effluents via this pathway.

ACTION 101 -

With the number of channels OPERABLE less than required 1 by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue for up to 30 days provided that, at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, grab samples are l' collected and analyzed at a limit of detection of at least.
