August 15, 1986 VP-86-Oll7 Director of Nuclear Reactor Regulation Ms. Elinor G. Adensam, Director Project Directorate No. 3 Division of BWR Licensing U. S. Nuclear Regulatory Commission Washington, D. C. 20555

Dear Ms. Adensam:

Reference:

1) Fermi 2 NRC Docket No. 50-341 NRC License No. NPF-43
2) Detroit Edison to NRC Letter, " Revised Proposed Technical Specifications for the Alternative Shutdown System",

VP-86-0091, dated July 15, 1986

Subject:

Editorial Changes to the Proposed Technical Specifications for the Alternative Shutdown System Reference 2 requested an amendment to the Fermi 2 Technical Specifications for the Alternative Shutdown System. The marked up Technical Specification pages submitted with Reference 2 did not include all'of the administrative changes required to incorporate the changes. The index was not included, the proposed Table and Bases numbers were not consistent with the format of the rest of the Fermi 2 Technical Specifications and the word "and" was inadvertently omitted from Bases i

3/A.3.10.

l In no way do these changes affect the technical content of the proposed Technical Specifications nor do they effect any conclusions previously reached in prior submittals. The attached markup of the Technical Specification pages include the required administrative

changes, revisions and provide for a consistent format.

ACTION: With the mair turbine bypass system inoperable, restore the system to DM RAELE status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or take the ACTION required by Specification 3.2.3.

SURVEILLANCE REQUIREMENTS 80 4.7.f The main turbine bypass system shall be demonstrated OPERABLE at least once per:

a. 92 days and during each COLD SHUTOOWN, by cycling each turbine bypass valve through at least one complete cycle of full travel, and
b. 18 months by:
1. Performing a system functional test which includes simulated 9 automatic actuation and verifying that each automatic valve actuates to its correct position.
2. Demonstrating TURBINE BYPASS SYSTEM RESPONSE TIME to be less than or equal to 300 milliseconds.

INSTRUMENTATION BASES 3/4.3.10 "3/4.3/lE APPENDIX R ALTERNATIVE SHUTDOWN INSTRUMENTATION AND CONTROLS

-_ J The OPERABILITY of the alternative shutdown system ensures that a fire will not preclude achieving safe shutdown. The alternative shutdown system instrumentation, control circuits, power circuits and transfer switches are independent of areas where a fire could damage systems normally used to shutdown the reactor. Thus, capability is consistent with General Design Criterion 4 Appendix R to 10 CFR 50.

3/4.7.9 APPENDIX R ALTERNATIVE SHUTDOWN AUXILIARY SYSTEMS ' ,

The systemu identified in this section are those utilized for Appendix R Alternate Shutdown but not included in other sections of the Technical Specifications. The action statements assure that the auxiliary systems will be OPERABLE or that acceptable alternative means are established to achieve the same objective.

There are four independent Combustion Turbine-Generator units

. onsite. Unit 1 has a diesel engine starter and thus can be started independently from offsite power. CTG Units 2, 3, and 4 have AC-motor starters and rely on a 480-volt AC feed. The phrase " alternate source of power", as used in Specification 3.7.9, action statement b.2, is

(. ) defined as a source of power that is not reliant on offsite power for starting (if required) or operating (if already running) and capable of supplying the required loads on the 4160-volt busses associated with the Alternative Shutdown System. y FERMI - UNIT 2 B 3/4 7-5 l
