Subject:

Report of Potential 10CFR50.55(e) Item on Equipment Supported frm Block Walls (#84)

Dear Mr. Keppler:

On December 13, 1982, Detroit Edison's Mr. D. Ferencz, Acting Supervisor-Construction Quality Assurance, telephoned Mr. H. Wescott's office of NRC Region III to report on a potential prcblem of supporting equipment frun block walls at the Fermi 2 site.

It was recently discovered that portions of the security system (control panels, card readers, pull boxes, and 4" rigid conduit) have been installed on block walls. Also, the fire detection devices have been mounted to those same walls.

The above installations conflict with Edison's response to NRC Bulletin 80-11 (Edison letter EF2-52,623 frcIn Mr. H. Tauber) . This response stated, in part, that piping and equipuent is not supported on block walls. hhere items were on the walls, they either weighed less than 2% of the wall weight, or had been included in the design.

Troy Engineering plans to conduct an analysis of all equipment currently attached to the walls to detemine the loading.

Another report on this item, either interim or final, is scheduled to be sent on or before May 12, 1983. If you have questions concerning this matter, please contact Mr. G.M. Trahey, Assistant Director-Project Quality Assurance.

Very truly yours,
