ACTION STATEMENTS ACTION 35 - With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue for up to 14 days provided that prior to initiating a release:

At least two independent samples are analyzed in a.

accordance with Specification 4.11.1.1.1, and b.

At least two technically qualified members of the facility staff independently verify:

1.

The discharge line valving, and 2.

The manual portion of the computer input for the release rate calculations performed on the computer, or the entire release rate calculations if such calculations are performed manually.

Otherwise, susperd release of radioactive effluents via this pathway.

Yt (2) The principal gamma emitters for which the LLD specification applies

-2 include the following radionuclides:

Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, and Xe-138 in noble gas releases and Mn-54, Fe-59, Co-58, Co-60, C

Zn-65, Mo-99, I-131, Cs-134, Cs-137, and Ce-141 in Iodine and particulate 4g releases. The LLD for Ce-144 is 5x10 8 pCi/mli This list does not mean jy that only these nuclides are to be considered. Other gamma peaks that are
