Operability of CMS During Reactor Operation Appropriate instructions have been revised to include the bulletin requirements. Proposed technical specifications were submitted to NRC-NRR on March 3,1981 and have been withdrawn at NRR's request. We have been unable to determine limits on service life of system components; therefore, repair or replacement is presently based on the system operability.

bulletin. Refer to the response to item 5 regarding exceeding system design specifications.
If you have any questions, please call Jim Domer at FTS 858-2725.
