Box 236 Hancocks Bridge, New Jersey 08038 Nuclear Department TITLE: APPENDIX R/BREAKER COORDINATION "AS FOUND" REVIEW (PRE-AUDIT 1987) 1~0 PURPOSE To provide/document the methodology to be used to complete the review of Appendix R/breaker coordination impact for Salem Unit 2 for the design contiguration of September 1987.*

2.0 SCOPE This effort involves a review of the identified associated*

circuits with a common power source, as defined in Generic Letter 81-12. These associated circuits shall be defined in accordance with.the 1987 Salem Unit 2 Safe Shutdown model and a review of the electrical drawings and the Appendix R Area Assessments.

S-C-M200-NDM-061Q-0 Page 2 of 3 Date: . 2/18/88 4.0 DISCUSSION In response to a request by the NRC (reference 3.12), a review of

.the electrical distribution configuration concentrating in the area of breaker coordination will be performed on the basis of an Appendix R postulated exposure fire hazard. The configuration under study will b~ the distribution system in its pre-restart rnodif ication format *.

An engineering evaluation will be issued at the completion of this effort to document all findings.

4.1 Associated Circuit (common power source) Methodology 4.1.1 Utilize 1987 Salem Shutdown Model to review Salem Electr1cal Single Lines and identify safe shutdown and associated circuit loads.

4.1.2 Review the Tenera Unit 2 Appendix R Area Assessments to determine safe shutdown trains that will be utilized to achieve shutdown. This information will serve to identify "associated" safe shut~own cables for analysis.

4.1.3 Once associated circuits are identified, document voltage level, safety ~hannel, cable route and length, fire area, and reference drawings on cable input forms (Attachment A).* Information as to whether the raceway is fire wrapped will aiso be provided.

4.1.4 Define where the breaker becomes coordinated.

• Define what level of short circuit current/cable length at which the co?rdination occuis.

4.1.5 Should the breaker not be coordinated, review for protection with fire wrap.

• 4.1.6 Should neither breaker coordination nor fire barriers be acceptable for mitigating the associated ~ircuit's expos~re, review ~he area for exemption request commitments.

4.1.7 Sh6uld neither breaker coordination, noi fire wrap, nor exemption request commitments mitigate exposure fire damage, review for application of AOP-ELEC or EOP-LOPA.

s-c.'.-M200-NDM- 0610:-0 Paqe 3 of 3 Date: 2/18/88 4.1.8 The comment section of the cable input forms shall be utilized to disposition each associated circuit, and provide data for preparation of the final engineering *evaluation.

5.0 ACTION Personnel assigned to*Appendix R/Breaker Coordination Task Force shall utilize the methodology provided in this design memo.

6.0 SCHEDULE In accordance with the commitments established by PSE&G upper management, the effort is scheduled to be completed by March 4, 1988.
