Docket No.:
50-412 Mr. John J. Carey Vice President, Nuclear Duquesne Light Company Robinson Plaza Building, No. 2, Suite 210 PA Route 60 Pittsburgh, Pennsylvania 15205
Dear Mr. Carey:
Subject:
Beaver Valley Power Station, Unit No. 2 (BVPS-2) - Backfit Status
Reference:
Letter dated May 15, from J. J. Carey, DLC, to H. Thompson, NRC I have reviewed your letter of May 15, 1985 to me on the BVPS-2 backfit items status, and would like to update the current status of these backfit items.
The following items are resolved and closed in the final draft SER forwarded to DLC on June 6, 1985:
a Motor Operated Accumulator Isolation Valve b
Spent Fuel Pool Heat Load c
Class IE Power for Lighting and Comunications Systems d
Alarm for Rocker Ann Lube Oil Reservoir e
Diesel L.O. Fill Procedure f
Application of GDC 5 to Communication Systems g
Underestimation of Atmospheric Dispersion Conditiens h
Application of GDC 4 to Lighting Systems i
Snow and Ice Loads j
Application of GDC 2 and GDC 4 to Communication Systems, Review Criteria for Probable Maximum Precipitation (PMP)
I would like to take this opportunity to clarify a point for the record that I made in my April 5, 1985 letter to you on PMP.
In that letter, I noted that we had withdrawn our request for DLC to use Hydromet 51 or 52 procedures for evaluating PMP. However, I should also have noted that the staff would use Hydromet 51 or 52 procedures and would perform our own analysis ofslocal flooding at BVPS-2.
The results of the staff's analysis showed water levels would exceed door sill elevations of buildings, and the staff requested DLC to determine whether water will enter safety-related buildings and if so to provide an evaluation of how this water will affect the plant's ability to operate or to be safely shut down if necessary. DLC has provided a response to the staff's request by a letter dated May 17, 1985. The staff is presently reviewing this.
W Fire Suppression in the Cable Spreading Room My decision on this issue will be completed by the end of this month. The ma,ior area of concern is the adequacy of access to the cables in the northwest corner of the cable spreading room.
Steam Generator Level A meeting sumary containing my decision to accept the current design pending resolution of USI A-47 will be issued by the end of this month. Still pending is my evaluation as to whether an exemption from 10 CFR 50.55a(h) is required.
Soil Structure Interaction In a letter dated March 12, 1985 from E. J. W0olever, DLC, to H. R. Denton, NRC, DLC identified an additional list of open issues, including Soil Structure Interaction, that were being discussed with the NRC staff. This letter also indicated that DLC hoped to resolve these issues without the need to submit them for review under NRC backfit procedures.
In the Reference letter, you list Soil Structure Interaction as a backfit item; however, our files do not contain a request for review of this issue under the NRC backfit procedures. A technical meeting has been scheduled with DLC and Stone and Webster for June 19, 1985 to discuss the issue. After this meeting we may be better able to define what, if any, backfit issue is developing on this item.
Application of R.G. 1.26 to Areas Excluded by R.G. 1,76
~
The staff had a meeting with DLC on May 14, 1985 in which DLC agreed to provide a response to the staff request for additional infomation by the end of June 1985. We expect this issue to be resolved following the receipt of your docketed information.
Air Dryers for Emergency Diesel Generator In a letter dated May 28, 1985, DLC informed us that air dryers will be provided for BVPS-2 emergency diesel generators. The staff considers this acceptable.
To close out this item, we need DLC to docket the information on the inspection of the air dryers.
Illumination Levels in Excess of SRP Criteria The staff has reviewed the May 6, 1985 DLC response on the BVPS-2 illumination level issue. This most recent response commits to provide an absoiute minimum of 0.5 fc and 2.0 fe, in accordance with Table II of the IES guidelines, for slight and high hazards respectively located in the pathway. Since Table II of the IES guidelines does not define slight or high hazards, we will be requesting your staff to provide for our review the DLC definitions of hazard conditions.
If the staff finds no problem with these hazard definitions and if the locations and passageways in BVPS-2 through which personnel must transit to reach safety related equipment areas meet these hazard definitions, we consider the above

These last three backfit items appear to be on their way to being resolved; therefore, as we agreed in our telephone call of June 19, 1985, a backfit appeal meeting for these items may not be needed.
If you desire further information concerning the resolution of these items, please contact me or B. K. Singh.
