A. Schwencer, Chief Operating Reactors Branch No. 1 Division of Operating Reactors Washington, DC 20555
Reference:
Beaver Valley Power Station, Unit No. 1 Decket No. 50-334 Auxiliary Feedwater/ Containment Pressure Analysis Centlemen:
Enclosed are six (6) copies of the results of an analysis of the response of containment pressure to a steca break accident inside containment with extended auxiliary feedwater flow to the affected steam generator.
This analysis was. performed as a result of questions asked by members of your staff during the month of September, 1979.
The results of this analysis indicate that the postulated event will not result in a containment pressure greater than that for which the structure has been designed.
Very truly yours, 7

Mr. Gilbert W. Moore Duquesne Light Company Novenber 7,1979 435 Sixth Avenue J.O. NO.13352.03 Pittsburgh, PA 15219 DLS 15169 Dear Sirs BEAVER VALLEI POWER STATION - UNIT NO 1 J.O. B0. 13352.03 (JXILIARI FEEDWATER/ CONTAINMENT PfESSURE ANALYSIS This transmittal completes a Stone & Webster analysis effort relative to the effects of a main steamline break (HSLB) on containmant pressure considering unisolated auxiliary feedwater system (AFS) flows for up to thirty (30) minutes after initiation, as requested by the ERC staff in a recent meeting.
At Duquesne's request, S&W attended an NRC meeting on the above subject in Bethesda on 9/21/79.
In addition to S&W and Diquesne, VEPCO repre-sentatives were in attendance. As a result of the 9/21/79 meeting, S&W has completed analys is that de:nonstrate the acceptability of the existing BV-1 AFS with respect to a MSLB and the resulting containment pressure transients.
The results of the completed analyses are presented in Attachment 1.
These results ars =4m41=r to the pra14=4 nan results telecopied by S&W to the RRC on 10/1/79 and supplemented by additional infornation concerning analysis parameters on 10/3/79 Both of the telecopied transnittals are includv4 as At+- hment 2.
The final results (Attachment 1) show a lower peak containmant pressure than the preliminary results (Attachment 2).
This reduction is due to the elimination of mass and energy blowdown that was added to cent.=in==nt from the two intact steam generators in the pre 14=4n=n analysis. also contains the important assumptions used in the analyses. presents the more significant plant parameters for BV-1 that might be useful as a basis to judge the applicability of the BV-1 analysis to similar plants. Attachment 4 shows a si=plified sketch of 'the Auxiliary Feedvater system functional arrange =ent.

R The final results shown in Attach.nent 1 demonstrate that the contain= ant design pressure (45 peig) is not azeeeded hy the continued unisolated-AFS flow for more then 30 min. assuming that the affluent discharged to the con +24-t is steam. h analysis also deemnstrates that for the 4 9 ft2 pressures are reached as a result of the initial break,theppbreak,theinitialpeakpressurethatoccurs For the 1 4 ft blowdown.
a few minutes after the break occurs is conaida M to be the. limiting peak pressure reached for this accident, however h analysis was continued out to 30 minutes at the request of the ERC staff.
N terminations of the pressure transients shown in Attachment 1 '"#
result from two differert calculational mechanisms. The 4 9 fr,2 break analysis calculates the decrease in heat sources available (heat transfer coefficient assumed constant) until AFS temperature is reached. This resultg in an abrupt decrease of steam flow to W containmant.
h 1 4 ft break analysis assumed AFS isolation at 30 min. also resulting in an abrupt decrease in steam flow to the containment.
It should be emphasized that cont =4]ftt pressures predicted at 30 min.
are unrealiatiolly high for the 1.4 break since it was assumed that the availahle energy in the primary system remains nearly constant with time. Therefore, the steam flow to the containment equivalent to the AFS flow rate to the affected steam generator roeults in more staan being generated than the system can provide results in more steam being generated than h system can provide over a 30 min. time period. Based on the analysis evaluation, isolation of the==414=v feedvater system is not necessary in order to preclude con +24===t overpressurization.
E&W requests DI4 approval to forward Attachment 3 to VEPCO for use as part of their activities related to this same concern for the Surry plants. A comparison of BV-1 and Surry 1 & 2 parameters was requested by MRC at the 9/21/19 meeting attanded by Duquesne and VEPCO.
Following telephone conversation with Mr. J. Carey of Duquesne Light Co.,
B&W has re-evaluated h unisolated feedvater piping volume and the feed-water control valve closure time used in the preitmin=q analysis and the approprintemees of both parameters to Beaver Valley Unit 1.
S&W utilisod a feedvater control valve closure time corresponding to greater than the average of the Beaver Valley 1 test results. However, main feed fleva consistent with a depressurized steam generator were assumed.
h s, the mass of main feedvater entering the affected generator has been enveloped in the analysis.
If you have any questions, do not hesitate to call us.
Very truly A

TELECOPIED /.M>' riur CAT" ~ .// /n.,. 8 m Assumptions: - =,,,, 1. Main steam non-return valve functions instantaneously to isolate the raulted steam generator break from reverse main steam flow. 2. Blowdown rate of the faulted steam genetstor is calculated by S&V/W, feedwater flow control valve goes to full open, zero pressure drop through the steam generator for 30% and 103% cases. 3. The two intact steam generators stay pressurized. 4. Steam generators are isolated by controls sensing the break. 5 Auxiliary feedvater flow is available within ten seconds, with run-out flow going preferentially to the faulted steam generator per system hydraulics. 6. Heat transfer coefficient is constant, heat transfer vs. time per computer code. (~ 1200 BTU /lb) 7. Containment backpressure is 20 psig for all cases. 8. Single active failure is one CIB resulting in minimum safeguards; 1.e., failure of one-half of the containment sprays. 9 No operator action is assumed.
- 10. All auxiliary pumps operational.
