Attention:
Mr. B. J. Youngblood, Project Director PWR Project Directorate No. 4
Subject:
Catawba Nuclear Station, Unit 2 Docket No. 50-413
Dear Mr. Denton:
. As an outgrowth of the NRC Staff's review of the proposed Technical Specifica-tions for Catawba Unit 2, Duke Power was requested to propose a te.hnical specification for the Condensate Storage Tank (3/4.7.1.3, NUREG-0452, Rev. 4).
As discussed in Section 10.4.9.2 of the Catawba FSAR the condensate grade sources of water for the Auxiliary Feedwater System are the auxiliary feed-water (CA) condensate storage tank, upper surge tanks and condenser hotwell.
These sources.are non-seismic and non-safety grade.
The. Standby Nuclear Service Water Pond serves as the ultimate long-term safety related source of water for the Auxiliary Feedwater System.
This aspect of Catawba Unit 2 is essentially identical to Catawba Unit 1 and McGuire Units 1 and 2.
Because the condensate grade water sources are not safety related and are not relied upon in mitigating the consequences of design basis accidents, we do not feel that the' addition of a condensate storage technical specification is necessary. This conclusion is consistant with previous reviews by the NRC Staff in issuing the Technical Specifications for Catawba Unit 1 (NUREG-1106),
McGuire Unit 1 (NUREG-0759) and.McGuire Units 1 and 2 (NUREG-0964).
Rather than. delay the Staff's review of the Catawba Unit 2 Technical Specifi-cations and the subsequant isssance of the Operating License, Duke herewith proposes the requested condensate storage Technical Specification.
It is our feeling that the NRC's Ted mical Specification Improvement Project (September 30, 1985 memorandum from D. H. Beckham to H. R. Denton) will provide a near-term opportunity to re-negotiate the necessity of the attached technical specification.
Very truly yours,
&k Hal B. Tucker
