SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT N0. 11 TO FACILITY OPERATING LICENSE N0. DPR-21 NORTHEAST NUCLEAR ENERGY COMPANY MILLSTONE NUCLEAR POWER STATION, UNIT NO. 1 DOCKET N0. 50-245
1.0 INTRODUCTION
By letter dated April 28, 1987, the Northeast Nuclear Energy Company (NNEC0) submitted an application to amend Facility Operating License No. DPR 21 for Millstone Nuclear Power Station, Unit No 1.
The proposed amendment would correct the Technical Specification (TS) Table 3.7.1 listing of primary containment isolation valves to reflect plant modifications.
2.0 DISCUSSION AND EVALUATION The licensee states that the proposed change to the primary containment isolation valve TS Table 3.7.1 reflects plant modifications (i.e., valves which are no longer primary containment boundaries, addition of new systems, valve relocation, etc.) and to increase the scope of the table to include not only valves and valves opened during power operation for testing and/or sampling purposes.
Valves proposed to be added to TS Table 3.7.1 and the l
two valves proposed to be deleted are associated with recent modifications i
to the Post Accident Sampling System, Containment Hydrogen /0xygen Analyzer l
System, Drywell Nitrogen Compressor System, Scram Discharge Instrument l
Volume System, and Control Rod Drive (CRD) System. Other corrections are proposed for the Recirculation Sample System, TIP System, Core Spray System.
Low Pressure Coolant Injection System, and Atmospheric Control System.
The staff reviewed the proposed changes on an individual system basis. The two valves to be deleted from the TS table are control rod drive hydraulic return check valves 301-95 and 301-98. These valves were removed when the CRD returns were rerouted to the "A" feedwater line in 1978. The licensee's analyses for adding each of the remaining valves to Table 3.7.1 were reviewed and found acceptable.

.. i In addition, the staff compared the Appendix J listing of all Primary i
Containment Penetrations with the proposed TS table. Discrepancies between these two lists, such as valve number changes, back-up manual or check valves, valves not automatically closed, and ESF suction valves that remain open, I
were discussed with NNECO.
NNECO's reasons for not including these valves l
in TS Tabl,e 3.7.1 had technical bases and were found acceptable.
Based on the above, the staff finds the' proposed changes to TS Table 3.7.1, Primary Containment Isolation, acceptable.

3.0 ENVIR0 MENTAL CONSIDERATION i
This amendment involves a change to a requirement with respect to the installation or use of facility components located within the restricted
{
area as defined in 10 CFR Part 20. The staff has determined that the i
amendment involves no significant increase in the amounts, and no significant increase in the types, of any effluents that may be released offsite and that there is no significant increase in individual or j
cumulative occupational radiation exposure. The Commission has previously l
issued a proposed finding that this amendment involves no significant l
hazards consideration and there has been no public comment on such finding.
exclusion set forth in 10 CFR 51.22(c)(9)gibility criteria for categorical Accordingly, this amendment meets the eli Pursuant to 10 CFR 51.22(b),
no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
4.0 CONCLUSION
We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Connission's regulations and the issuance of this amendment will not be inimical to the common defense or security or to the health and safety of the public.
