Catawba Nuclear Station - Docket Nos. 50-413/414 Proposed Technical Specification to Revise Allowable Unidentified Leakage Gentlemen:
On June 9,1986, Duke Power Company (DPC) submitted a proposed change to Technical Specification (T.S.) 3.4.6.2 to modify actions taken in the event Unidentified Leakage between 1 and 3 gallons per minute (gpm) occurs. The proposed amendment cought to allow continued power operation for up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> before proceeding to
-Hot Standby and ultimately Cold Shutdown. Subsequent discussions with NRC Staff have indicated a reluctance on the part of the Staff to permit continued operation with unidentified leakage in excess of I gpm. While DPC believes that these changes can be implemented without compromising safety, an alternative is provided in the attachments which will accomplish the intent of the original submittal while still being responsive to the concerns of the Staff. This revised amendment tpplication proposes that when Unidentified leakage exceeds 1 gpm the leak must bq identified within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or the affected unit be in Hot Standby in the followingt 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. The unit must be in Cold Shutdown in the following 102 hours0.00118 days <br />0.0283 hours <br />1.686508e-4 weeks <br />3.8811e-5 months <br />. This is l
cxpected to facilitate identification of the leak under elevated temperature and pressure conditions, while suberitical.
l This.is a revision to an existing application, and as such requires no additional L
rpplication fees. This revision supersedes the June 9, 1986 submittal in its cntirety. The changes to the June 9,1986 submittal are noted.
If any additional information is required to assist the review of this item, please contact Duke through normal licensing channels.
