August 14, 1986 W3P86-1952 A4.05 QA Mr. Robert D. Martin Regional Administrator, Region IV U.S. Nuclear Regulatory Commission 611 Ryan Plaza Drive, Suite 1000 Arlington, TX 76011

Subject:

Waterford 3 SES Docket No. 50-382 License No. NPF-38 Battery & Battery Rack Configuration

Dearg Mr. Martin:

Pursuant to the verbal request of NRC Region IV personnel on August 13, 1986 the following Justification for Continued Operation is provided regarding the NRC concern on the installation of Class IE batteries and racks at Waterford 3.

JUSTIFICATION FOR CONTINUED OPERATION The Class IE batteries and racks at Waterford 3 are installed according to the Gould Specifications delineated in Gould Drawing #060616D for NCX 1200 batteries and 060617D for NCX 2400 batteries. The configurations were seismically qualified by Gould.

The Resident NRC inspector has questioned the seismic mounting of the battery cells as there are gaps between the end cells and the end stringers of the racks. These gaps vary between 0 to 1.3 inches approximately. LP&L

,, has not received any formal notification from Gould to reduce the gaps, g@g However LP&L has requested GNB Batteries Inc. (previously Gould) to review ggn. these gaps and recommend corrective measures, if necessary.

oc j$@, CNB Inc. is in the process of analyzing the Waterford 3 concerns. In the interim, GNB has provisionally recommended that the spacings be reduced to

,'d less than 0.25 inches by either moving the end rails or by providing a

@@ spacer (wood, open cell styrofoam, or other GNB approved materials) between N4 the rails and the batteries.

m

@ LP&L has, as a precautionary measure, initiated a non-conformance work maa authorization to comply with the above recommendation.

Page 2 W3P86-1952 As this fix:

a) is recommended by the vendor as a precautionary measure, and b) has been implemented, LP&L does not consider that there is any safety concern associated with the class IE batteries at Waterford 3.

If the battery vendor's review concludes that the spacers are required to maintain the seismic qualification of the Waterford 3 batteries, a pe rmanent fix will be implemented during the refueling outage.
