Subject Braidwood Station Unita 1 and 2 Supplemental Response to Inspection Reports Nos.

50-456/89-011 and 50-457/89-011 NRC Dockg1_Nos. 50-456 and 50-451 l References (a) G.C. Wright letter to C. Reed dated ,

June 19, 1989 i (b) T.J. Kovach letter to A.B. Davis dated July 19, 1989 Dear Mr. Davist Reference (a) provided the results of the special safety inspection conducted by a NRC Emergency Operating Procedure Inspection Team at Braidwood Station on May 8-24, 1989. Reference (b) provided Commonwealth Edison Company's response to.the inspection report. In the response Commonwealth Edison committed to review the accessibility'of two valves (IRH8701B and 1RH8702B) located within the Braidwood Station Unit 1 containment during the just completed' Unit I refueling outage. The purpose of this letter is to provide the results of that review.

An evaluation of the accessibility of these valves was made independently by personnel from both the Braidwood Utation Technical Staff and the Architect / Engineer, Sargent and Lundy. Both evaluations concluded that there is clear access to the IRH8701B valve and no change is necessary, but

-that the access to the IRH8702B valve could be improved. A Minor Design Change Request (MCR20-1-89-063) has been submitted for review to the Station Modification Review Committee to make changes to improve the access to valve IRH8702B.

L The corresponding valves for Unit 2 (2RH8701B and 2RII8702B) will be reviewed for accessibility during.the upcoming Braidwood Unit 2 refueling outage, currently scheduled to begin March 17, 1990. When the results of this

. review are available, they will be submitted to the NRC, accordingly.
