ATTACHMENT II VALVE TEST PROGRAM - RELIEF REOUES S In accordance with 10 CFR 50.55A(g)(6)(1), relief is requested from specific regtdrements of Section XI as follows: 1. With respect to those Category A valves for which seat leakage is f sportant from a containment isolation standpoint but not. rom a system functional standpoint, the leakage rates will be determined at the test pressute speci-fled in Technical Specification Section 4.5.2, Local Leak Detection Tests (between 70 psia and 80 psia). Since these pressures are represcatative of system pressure at the valve during containment isolation, no exception is requested. NOTE: Application of IWV *420(c)(5) is not required in d.a testing of these valves. 2. Category C relief valve tests may be distributed over each refueling cycic such that the required number of relief valves will have been tested by the end of cach cycle. 3. It is unreasonable to follow the tining acceptance require =ents of ikV 3410 (c)(3) for valves with strnke ti=es under 10 seconds (ie, Palisades has had experience where a valve operates in i second one conth and 2 seconda the next; therefore, test frequency is required to be increased). As long as upper limits on stroke times are not exceeded, the following acceptance criteria for valves with stroke cines less than 10 seconds u_11 apply: If an increase in stroke time of 25% or more from the previous tes: for valves with stroke ti=u grester than 10 seconds or 50% or ' core for valves with stroke ti=e from 5 to-10 seconds, or an increase of 5 seconds for valves with stroke times under 5 seconds, test frequency shall be increseed to once each month until corrective action is taken, at which time the original ~ test frequency shall be resumed. Under the FSAR and Technical Specifications, the only valves which prese cly have safety-related stroke time limits of five seconds or less are the main-steam isolation valves. Since the above criteria vill not apply to the MS1V's, applicat"on of this criteria util not jeopardire any plant safety function. 4.
