FIRE PROTECTION ISSUES SURRY POWER STATION Serial No. 4 77 NO/SWB/jmj/SP4 Docket Nos. 50-280 50-281 License Nos. DPR-32 DPR-37 of r.gur :. Hiter dated February* I3:> 198i listed eight items of the Surry Power Statioh Fire Protection Safety Evaluation Report dated September 19, 1979 as "Unresolved Fire Protection Issues".
The purpose of this letter is to document the disposition of these items.
The following clarifications should document that the items listed in your February 13, 1981 letter as unresolved have been resolved.
3.1.4 Cable Tray Covers -
The cable tray covers were installed to comply with the Surry Power Station Fire Protection Safety Evaluation Report dated September 19, 1979.
This item was listed as unresolved in the February 13, 1981 letter because the Appendix R review was not complete and the reviewers had not determined what equipment and barriers Vepco was taking credit for to assure safe shutdown.
As demonstrated by Serial Number 885 and Serial Number 363 dated October 31, 1980 and June 18, 1982 respectively, safe shutdown capability does not rely on these tray covers.
Since the tray covers have been installed, this item should be closed.
3.1.10 Fire Barriers -
The fire barriers were installed to comply with the Surry Power Station Fire Protection Safety Evaluation Report dated September 19, 1979.
This item is resolved since safe shutdown capability does not rely on these barriers as discussed in 3.1.4 above.
3.1.30(1) Charging Pump Technical Specifications Vepco reviewed the Technical Specifications and concluded that the section 3.2 of the Technical Specifications as it now is written requires a charging pump from the opposite unit to be available at all times during operation of either unit.
Therefore, the Technical Specification is acceptable since it meets the requirement of item 3.1.30(1) of the FPSER.
