Dear Mr. Engelken:

Subject:

WPPSS NUCLEAR PROJECT NO. 2 POTENTIALLY REPORTABLE DEFICIENCY - 10CFR50.55(e)

ANNULUS PRESSURIZATION EFFECT ON PIPING SYSTEMS

Reference:

Letter flo. G02-81-13, dated January 22, 1981, RG Matlock, The Supply System, to RH Engelken, NRC Region V The Reference letter informed your staff of a potentially reportable deficiency regarding the effect of annulus pressurization on pi ping systems attached to or supported from the reactor vessel or sacrificial shield wall.

Although the analysis of resulting loads on pi pi ng systems and suppor ts is not completed at this time, the Supply System has concluded that this condition is a reportable deficiency under the terms of 10CFR50.55(e),

since it is a safety concern requiring extensive analysis which should have been, but was not, considered in the design of safety-related pi ping and supports prior to release for construction.

Final results of the ongoing analysis of piping systems and supports, by the architect-engineer, will be included in the "Plant Design Assessment Report for SRV and LOCA Loads", for the WNP-2 facility. It is anticipated that the final revision to the report will be submitted in June 1982. Since this matter was initially raised by the NRC staff in conjunction with their ongoing revieius on the WNP-2 docket (ref. WNP-2 FSAR, question 110.019) the

P I

Nr. R. H. Engelken Nay 26, 1981 Page Two G02-81-119 Supply System will address this concern in that forum, and does not anticipate providing a duplicate or supplementary report to NRC Region V.
