Mr. H. R. Denton November 7,1986 o Attachment I to IDENRC 86-210 Page 1 SAFE 1Y EVAWATICE Introduction
' Wolf Creek License Condition 2.c (11) states: " Prior to restart following the first refueling outage, nE shall sutznit for NRC review and approval an analysis which demonstrates that the steam generator tube rupture (SGTR) analysis presented in the FSAR is the most severe case with respect to the release of fission products and calculated doses. Consistent with the analytical asstmiptions, the licensee shall propose all necessary changes to Appendix A to this license".
%e SGTR analysis has been ca pleted and subnitted to the NRC for review (References 1, 2, and 3).. h is analysis : takes credit for Atmosgheric - Relief Valve (ARV) operation for SGTR mitigation and states that DE will sutznit a Technical Specification amendnent request concerning the operability of the ARV's in a SGTR event.
Appropriate Technical Specification requirements have been developed.
Se proposed requirements state that three of the four steam generator atmospheric relief valves shall be operable in Modes 1, 2, and 3. If only two ARV's are operable, this specification allows 30 days to return one of the two inoperable ARV's to operable status. If only one or no ARV's are operable, this specification allows'only 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to return to at least two operable ARV's. An action statanant is provided which allows the plant to start up if the Limiting Condition of ' Operation (ICO) is not met. % e proposed Technical Specification would not increase the surveillance requirements for the ARV's beyond those addressed in existing Specification 4.0.5. Finally, a footnote is included to specifically note that an ARV renains operable if its associated block valve is closed solely because of ARV leakage.
Evaluation Se purpose of the license ;-.c Ar.ad. request to incorporate technical
} specification ICO and surveillance requirements for the steam j generator ARV's into the Wolf Creek Operating License is'to assure the availability of mitigating equipnent assuned in the SGTR analysis.
Se technical specification requirements constitute additional limitations on facility operations and satisfy, in part, the specific requirements of License Condition 2.c (11) of the Operating License.
No requirements on ARV operability have been included in the existing
- Wolf Creek Technical Specifications because the ARv's have not been i
required in the mitigation of postulated accidents and transients.
i ne Wolf Creek Generating Station design includes four ARV's, one ARV for each steem generator. S e ARV's are safety-grade and have Class 1E electrical control circuits (Reference 4).

Mr. H.~R. Denton November 7, 1986 Att+ a. I to IG GIRC-210 Page 2 he operability of at least three of 'the four ARV's ensures that reactor decay heat can be dissipated to the atmosphere in the event of
'. a SGTR coincident with a loss of offsite power and that the Reactor Coolant Systen (RCS), can be cooled down to the point of Residual Heat i,
Removal System (RRR) operation. In the initial phases of a SGTR event, l the ARV's are relied upon for achieving proper RG subcooling i prior to equalizing pressures between the RG and the faulted steam generator. 'We proposed nunber of operable ARV's assures that subcooling can be adlieved within assuned time constraints' and in
> accordance with single failure assunptions used in the SGIR analysis.
4 For the RCS cooldown to RHR initiation, only one ARV is needed for the
[ heat removal required. Three operable ARV's are adequate, assuning that one of the operable valves is on the faulted steam generator, and r thus is not available for heat removal, and that one ARV fails to
- function in accordance with accident assunptions.
. The proposed Technical' specifications are applicable in plant '
i operational Modes 1, 2, and 3. Since the purpose of the ARV's is to provide for removal of reactor decay heat during the initial @ases of the SGTR event and during cooldown to RHR initiation, and since the RHR system is available in Modes 4, 5, and 6 this Technical Specification is only applicable in Modes 1, 2, and 3.
i Each ARV is equipped with a manual block valve, located near the ARV in the auxiliary building, to provide a positive shutoff capability should an ARV develop leakage. Se ARV is considered operable if the block valve is closed solely because of leakage. Closure of the block
{
valves of all ARV's because of leakage does not endanger the reactor
!.. core because decay heat can be dissipated with the steam line safety I
valves. Also, consistent with SGTR analysis assu@tions, a block valve can be used to control release of steam to the atmosphere.
%e restoration time periods provided in the proposed LCD Action statement are based on the low likelihood of having a SGTR event coincident with a loss of offsite power during the time period that
! one or more of the required ARV's is out of service.
period (30 days) for the case of one inoperable ARV isThe allowed time i longer than the time period (24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />) allowed when more than one ARV are inoperable.
%e surveillance requirements of the Wolf Creek inservice valve testing 1

Mr. H. R. Denton Novenber 7, 1986 Attachment I to RMDEC 86-210 Page 3 (bnclusions Based on the above evaluation, it is concluded that the proposed ARV Technical Specifications constitute new I00 and surveillance requirements which govern operability of existing equignent in the Wolf Creek design. It was also concluded that the proposed Technical Specifications would not adversely affect the conclusions in existing plant transient and accident analyses and that the proposed requirements provide acceptable operability limitations for ARV's consistent with the asstaptions used in the SMR anlysis. '1herefore, the level of plant safety described in the Wolf Creek FSAR is not adversely affected by the proposed amendnent.
