DOCKET NOS. 50-445 AND 50-446 SEISMIC AIR GAP DESIGN ADEQUACY SDAR: CP-86-55 (FINALREPORT)
Gentlemen:
On August 14, 1986, we verbally notified your Mr. I. Barnes of a deficiency involving a potential design inadequacy of the seismic air gap between the Auxiliary Building and Units 1 and 2 Containment Buildings. Our~1ast interim report was logged TXX-6935, dated November 11, 1987.
Specifically the ga) shown on design drawings did not appear. consistent with the loads required )y FSAR Section 3.8.1.3.2 which included extreme environmental temperatures. Our evaluation of this issue has confirmed that the existing seismic air gap between the Auxiliary Building and Units 1 & 2 Containment Buildings is acceptable for the loading combinations contained in the FSAR.
We have concluded that had this issue remained uncorrected, no condition adverse to the safety of plant operations would exist.
This issue is not reportable under the provisions of 10CFR50.55(e).
Records supporting this conclusion are available for your inspectors to review at the CPSES Project Site.
Very truly yours, l). ( 00nst b W. G.
