Group M PresMent U. S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555 SUBJECT; COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) - UNIT 2 DOCKET fC. 50-446 HIGH ENERGY L1HE BREAK ANALYS15 SDAR CP-87-133 (SUPPLEMENTAL REPORT)

Gentlemen:

On December 10. 1987, TV Electric orally notified the NRC of deficiencies involving the high energy line break (HELB) analysis determined to be reportable under the provisions of 10CFR50.55(e). The last report on this issue, TXX-91292 dated September 16, 1991, provided a status of the Unit 2 corrective and preventive acy. ions for this issue followed by a brief discussion of the SDAR's which were previously consolidated under this issue. The purpose of this report is to clarify the performance of target identification surfeys for safety related equipment as discussed in the last report. I TV r.lectric letter TXX 91292 indicated that target identification surveys would be performed for Unit 2 to identify safety related targets affected by -

HElBs. These surveys will be performed and documented for those safety relatcd and non-safety related systems and components specifically discussed in the Pipe Rupture dafe Shutdown Analysis Calculation as necessary to mit'. gate the consequences of postulated pipe breaks and achieve a saf e shutdown condition.

As previously discussed in IXX 91292, all actions necessary to resolve this deficiency fcr Ur.it 2 will be completed before Unit 2 fuel load.

Sincerely, William J. C ill. Jr.
