Dear Mr. Davis:
This is to inform you of our decisions on changes to the Standard Technical Specification (STS) NUREGs proposed by the NEI Technical Specification Task Force (TSTF). Those travelers Approved are TSTFs -076, R.1, -204, R.2, -242, R.1, -284, R.3, -297, R.1, -322, R.2, and -340, R.2. Those travelers Modified are TSTFs -207, R.3, -283, R.2, -287, R.4, -
342, R.0, and -352, R.0. The traveler -333, R.1 is Rejected. Our comments on those travelers Modified or Rejected have been previously provided or are enclosed.
Please contact me at (301) 415-1161 or e-mail wdb@nrc.gov, if you have any questions or need further information.
Sincerely,
/RA/

SUMMARY
TSTF-352, R.0: Modify
CEOG) regarding pressurizer water level and pressurizer safety valves are acceptable. The bases of our acceptance is that in Mode 3, a heatup transient (ie, loss of main feedwater or feed water line break,etc) would lead to miner effects on RCS pressurization. Therefore, the proposed change of completion time in the required action B.2 from 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to (24) hours for going to Mode 4 would not cause significant safety concern.
- 2. The proposed changes to STS 3.7.4 and STS 3.7.6 (For BWOG, WOG & CEOG) regarding Atmospheric Dump Valves and Condensate Storage Tank are acceptable. The bases of our acceptance is that if there is sufficient safety grade condensate storage capacity to support the decay heat removal during Mode 3 operation, there is no safety impact due the change of completion time in the required action C.2 (STS 3.7.4) and B.2 (STS 3.7.6) from (18) hours or (12)hours to (24) hours for going to Mode 4.
- 3. The proposed changes to STS 3.4.12 (For BWOG, WOG & CEOG) regarding LTOP require additional information for the staff review. Current STS 3.4.12 require depressurization of RCS and establish RCS vent within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> (For WOG & CEOG) or 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (For BWOG) when both LTOP trains become inoperable. TSTF-352 propose to change this completion time to (24) hours. This proposed change would increase the risk of reactor vessel integraty. Additional justification is needed per the requirements of R.G. 1.177 and SRP 16.1. The required additional information will be reviewed by the combined effort from SPSB and SRXB.
