Subject:
Beaver Valley Power Sd'.ation, Unit No. 1 and No. 2 i
BV-1 Docket No. 50-334, License No. DPR-66 BV-2 Docket No. 50-412, License No. NPF-73 e
Response to Verbal Request on November 4, 1993 (TAC Nos. 76891/76892)
A conference call was held on November 4, 1993, concerning Technical Specification Change Request Nos.
179/42 for Beaver Valley Power Station (BVPS)-
Unit No. 1 and No.
2, respectively, submitted to the i
NRC on June 14, 1990.
The NRC reviewer questioned the designation for the BVPS Unit No.
1 480 volt emergency busses.
The proposed Technical Specification Change Nos. 179/42 denotes the two emergency i
busses as "8N" and "9P."
The Updated Final Safety Analysis Report I
(UFSAR)
Figure 8.1-1 denotes the same two emergency busses as "1N" i
and "1P."
i In
- addition, the NRC reviewer also noted that on BVPS Unit No. 2 UFSAR Figure 8.3-3, the DC busses are not as clearly identified as they are on UFSAR Figure 8.3-14.
Specifically, DC busses 2-3 and 2-4
{
appear to be designated as
" BAT *BKR2-3" and " BAT *BKR2-4."
It was l
stated that these designations are in reference to the-battery-I breakers and were not intended to be the DC bus designation.
The correct designations are DC bus 2-3 and DC bus 2-4.
l t
Agreement was reached that a review of the existing terminology against standard nomenclature, as it applies to the above figures, would be conducted and changes made where consistency and clarity j
could be improved.
Any changes to the UFSARs will be accomplished i
during the next updtte cycle.
j If you have any further questions ~ or require additional information concerning the
- above, please contact G.
S.
Sovick at (412) 393-5211.
i Sincerely, i
