g INTRODUCTION By "05000413/LER-1985-065, :on 851115,motor-driven Auxiliary Feedwater Pumps auto-started Following Main Feedwater Pump Turbine Trip.Caused by Defective [[Equipment trip" contains a listed "[" character as part of the property label and has therefore been classified as invalid. Breaker Test Procedure.Procedures Revised|letter dated December 13, 1985]], Duke Power Company, et al., (the licensee) proposed changes to the Technical Specifications (TS) for Catawba Nuclear Station, Units 1 and 2 that would involve: (1) a revision to the reporting requirements related to primary coolant iodine spikes, and (2) the deletion of existing TS requirements to shutdown the facility if coolant iodine j;; ;
activity limits are exceeded for 800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br /> in a 12-month period. The pro-posed changes are in accordance with NRC Generic Letter No. 85-19 dated September 27, 1985.
EVALUATION Generic Letter 85-19, Reporting Requirements on Primary Coolant Iodine Spikes, is part of an ongoing effort to delete unnecessary reporting requirements.
It has been determined that reporting requirements related to primary coolant specific activitiy levels, specifically iodine spikes, can be reduced from a short term report to an item to be included in the Annual Report.
It has also been determined that existing shutdown requirements based on ex-ceeding the primary coolant iodine activity limits for an accumulated period of over 800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br /> are no longer necessary. This is based on an improvement in the quality of nuclear fuel over the past 10 years and the fact that appro-priate actions would be initiated long before approaching the limit as currently specified.
Generic Letter 85-19 reports these findings and presents model TS in Standard Technical Specification format which reflect these findings. The licensee has proposed amending the Catawba Units 1 and 2 TS to match the model TS presented. We find the revisions to the reporting requirements and the deletion of requirements to shutdown the facility if coolant iodine activity limits are exceeded for 800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br /> in a 12 month period to be consistent with the Generic Letter and model TS and, therefore, to be acceptable.
ENVIRONMENTAL CONSIDERATION The amendments involve a change in use of facility components located within the restricted area as defined in 10 CFR Part 20 and changes in requirements.
The staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that a704080271 870401 PDR ADOCK 05000413 P

may be released offsite and that there is no significant increase _in indivi-dual or cumulative occupational exposures. The Commission has previously_
issued a proposed finding that the amendments involve _ no _significant hazards consideration, and there have been no public_ comments on such finding.
Accordingly, the amendments meet the eligibility criteria for categorical ex-clusion set forth in 10 CFR Section 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental-assessment need be prepared in connection with the issuance of the amendments.
CONCLUSION The Comission made a proposed determination that the amendments involve no -
significant hazards consideration which was published in the Federal Register (51'FR 30565) on August 27, 1986, and consulted with the state of South s*
Carolina. No public comments were received, and the state of South Carolina did not have any coments.
We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Connission's regulations, and the issuance of the amendments will not be inimical to the comon defense and security or to the health and safety of the public.
