The consequences of failing to satisfy the degradation test aqceptance criterion while in MODES 1-4 are geverned by the Action Statements of TS 3.6.1.7.
The Action Statements prescribe three alternative actions to be taken within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> if the leakage rate exceeds the prescribed limit. The Surveillance Requirement in TS 4.6.1.7.2 reouires that once per 92 days, :r : :t:;; :d te:t 5:: 4, each containment ventilation l
penetration with purge valves having resilient materiel seats is to be iemenstrated eperable by verifying that the leakage rate is within the specified acceptance criterion. We have reviewed the licensee proposal regarding the testing of resilient seats of the containment ventilation purge valves and find that the revised TS adequately address our cencerns.
The limiting Condition for Operation of TS 3.6.1.7 currently requires that the 48-inch containment purge supply and exhaust isolation valves will remain sealed (deactivated and, secured closed) while reactor coolant temperature exceeds 200' F, as reconsnended by Item II.E.4.2.6 of NUREG-0737.
In proposed TS 3.6.1.7.b. the 8-inch mini purge supply and exhaust contain-ment isohtien valves may be open for safety-related reasons including control of containment pressure and reducing airborne radioactivity.
Furthermore, offsite dose :nalyses and the minimum containment pressure i
analvsis for the existing Emergency Core Cooling System per'ormance capability evaluation were based on the use of 18-inch isolation valves.
The analyses remain valid and are more conservative for the 8-inch valves.
We conclude that the revised TS covering the use of the mini-purge systen is acceptable.
By letter dated April 19, 1985, the licensee advised that additional leakage testing and a study to reduce containment building purging is the initiation of a requirement for backfitting.
During subsequent discussions between the KRC staff'and the licensee staff, agreement was 4
reached to proceed with TSs to meet current regulatory requirements relating to the issue of purging or venting of reactor containments. Therefore, the issuance of the licensee's proposed TS changes will satisfactorily resolve the backfit question of the licensee's letter dated April 19, 1985.
3.0 ENVIRONMENTAL CONSIDERATION
S i
These amendments change a requirement with respect to installation or i
use of a facility component located within the' restricted areas as defined j
in 10,CFR Part 20 and changes to the surveillance requirements.
1 The staff has detertnined that these amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that nay be released off site and that there is no significant increase in individual or cumulative occupational radiation exposure. The Cemission has previously issued a proposed finding that these amendments involve no significant hazards consideration, and there has been no public coment on such finding. Accordingly, these amendments meet the eligi-Corrected Page h$
