Ssetion-I - Dencription of the Amandment This proposed amendment to Appendix A'of the James A. FitzPatrick Nuclear Power Plant Facility Operating License changes the safety / relief valve (SRV) operability requirements contained in
' Specifications 3.5.C, 3.5.D and 3.6.E. Currently, when an SRV becomes s '
or is found to be inoperable, continued reactor operation is permissible for only thirty days unless the valve can be repaired and made operable. If more than one valve becomes inoperable, continued operation is permissible for only seven days. If the affected valve (s) is part of the Automatic Depressurization System (ADS), continued reactor operation is permissible for: only 7 days with one inoperable; and, only 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> if more than one is inoperable. In addition, if one or more ADS valves are inoperable, HPCI System operability is also required.
The proposed changes would affect the limiting conditions for operation only until the October 1982 refueling outage. With one non-ADS SRV inoperable, continued operation would be permissible for an indefinite period with no power level or other restrictions. With two or more SRV's inoperable, the existing limiting conditions for operation are still applicable.
Additional changes delete the requirement for continuous monitoring of the integrity of safety / relief valve bellows; change specification numbers and references as required; and, correct typographical errors.
The changes in this proposed amendment are contained in new pages 76c, 142b, 143a, and 143b.
Section II - Purpose of the Amendment The proposed changes will delete conservative limiting conditions for operation which are not necessary to assure the safe operation of the plant or to protect the health and safety of the public.
The proposed amendment requires only the operability of sufficient SRV's to assure plant safety.
Section III - Impact of the Amendment The proposed amendment provides revised limiting conditions for operation when an SRV is inoperable for any reason. It is also intended to address concerns of the NRC staff that SRV leakage, as indicated by elevated SRV tailpipe temperatures, renders the affected valve inoperable. These concerns have been expressed as a result of a recent increase in one SRV tailpipe temperature.
SRV leakage is not monitored directly but is indicated by increased
. tailpipe thermocouple and acoustical monitor readings. The possibility of proposing SRV tailpipe temperatures at which the valve would be declared inoperable, because of leakage, has been investigated.
General Electric (the NSSS vendor) and Target Rock (the SRV vendor) have both stated that they have not been able to identify or develop a definitive correlation between leakage and tailpipe temperature, by calculation'or by using empirical data. However, "as found" testing conducted by Target Rock for one utility showed that a 400 to 600F increase in tailpipe temperature indicates a leakage rate from neglible up to 200 pounds per hour. Further testing by Target Rock has
- - y
indicated that a leakage rate of 200 pounds per hour sh'ould not affect SRV cetpoint or response time (Reference C). Therefore, the existing elevated tailpipe temperature does not conclusively indicate that the valve is inoperable. However, a new specification, 3.6.E.5, is also proposed to specify actions which will be taken if significant increases occur in safety / relief valve discharge pipe temperatures or acoustical mon _itor readings.
There are several possible physical mechanisms by which leakage may affect SRV per formance. The possible physical mechanisms allow one to postulate either an increase or decrease in the setpoint due to leakage. Therefore, both possibilities have been reviewed for their impact on plant safety.
- If the setpoint decreases, there is a potential for increased loads on the torus during a transient which results in multiple SRV actuation. This issue was reviewed in Reference D, which granted an amendment to the Technical Specifications to allow changing the setpoint of one SRV from 1140 psig to 1090 psig. This decrease in setpoint.was found to be acceptable based on the Mark I containment improvements completed to date.
The effect of an SRV spontaneously opening, whether due to leakage or not, has been considered in the design basis of the plant. This design basis event was reviewed and approved in References A and B.
If the setpoint of a valve were to increase, the worst case would involve failure of the valve to open at any pressure, or in other words, total inoperability. This has been analyzed and the results reported in Reference E. The analyses as reported in this reference show that the FitzPatrick plant may be safely operated with any one of the SRV's totally inoperable, whether it is part of the ADS or not.
The effects of valve inoperability on the torus have been reviewed and found acceptable.
Technical Sepcification Basis 3.5.D also states that only six of '
the seven ADS valves are required to operate and that loss of one of the valves does not significantly affect the pressure relieving capability. A similiar conclusion was reached in Amendment No. 43 to '
the Facility Operating License (Reference F).
Section IV - Conclusion The incorporation of these modifications: a) will not change the probability nor the consequences of an accident or malfunction of equipment important to safety as previously evaluated in the Safety Analysis Report; b) will not increase the possibility of an accident or malfunction of a different type than any evaluated previously in the Safety Analysis Report; and c) will not reduce the margin of safety as defined in the basis for any Technical Specification; and d) does not constitute an unreviewed safety question.
