This report:

was transmitted to NRC in a 1 etter dated July 7, 198 The report summarized the method used to identify the masonry walls and safety-related equipment in the.ir proximity, discussed the classification of the walls, the original wall data, and the method of wall reevaluation and listed the* reevaluation priority and schedul The report also included.original construction. drawings showing the. layout of plant structures and wall location In a letter dated October 24, 1980, VEPCO requested an extension of the deadline for completion of the IEB 80-11 design reevaluation-from November 4, 1980 to the end of July, 198 VEPCO submitted an interim report on tha masonry wall reevaluation program to NRC in a letter dated November 3, 198 This report discusses changes to the wall identification numbers assigned to the walls irr the 60 day report and the deletion of some of the walls from the reevaluation progra The report states that reeva 1 uat ion has* been comp 1 eted on 41 of 89 masonry. wa 11 s, and that field 11as-builts 11 have been completed for all the wall Revi~w of Procedures for Accomplishment of IE Bulletin 80-11 Requirements The inspector examtned *stone* & Webster Procedure for As-Built Veri fi ca,ti on. of Masonry-Block Wa 11 s 11 *

Walkdown in Safety-Related Areas to Verify Accuracy,of Masonry.Wall As-Built Drawings The* inspector*, accompanied by S&W* and 1 i censee, engineers, examined the following walls to verify the accuracy of the as-built drawings which had been prepared for each of them:

(1) Auxiliary Building Walls (ID Numbers)

AB-45-10-4 AB-27-6-33 (West Elevation)

AB-15-0-4 (West Elevation)

AB-15-0-3 (North Elevation)

(2).Service Building Walls (ID Numbers)

The inspector made a cursory review of as-built drawings for severa 1 walls on the* elevation 2.:-0 level of' the auxiliary building during a fi-eld walkdown in this a.re These walls have been identified by the licensee as be.ing Class III walls, there is no safety-related equipment. in proximity. to. these wall The inspector also examined wa*ll number-lC-47-4,-20 i'n* the* Unit 1 containment buildin This wall, which' provides shielding around the* pressurizer wi 11 be, removed during tha: Unit: 1 steam generator replacement:-

which had not been noted in the licensee's initial identification and wall classification progra There were no walls in the diesel generator areas, however, there were severa 1 masonry wa 11 s on the elevation 45 level of the service building which had not been listed in the licensee's reports.as either Class I, II, or Ill wall Discussions with licensee and S&W engineers disclosed that all Class III walls (those walls which do not require reevaluation)

were probabley not included. in the report This area will be reviewed further by NRC in the resolution of the unresolved item discussed.in pargraph 6 Review of Quality Rcords Related to IE Bulletin 80-11 The inspector examined the following records relating to IEB 80-11 (1)

Floor plan drawings showing the location of masonry walls* in the. * service building, the auxiliary building, the fuel building and the Unit 2 containment buildin (2)
