Subject:
Beaver Valley Power Station, Unit No. 1 and No. 2 BV-1 Docket No. 50-334, License No. DPR-66 BV-2 Docket No. 50-412, License No. NPF-73 Response to NRC Bulletin 90-01, Supplement 1,
" Loss of Fill-Oil in Transmitters Manufactured by Rosemount" By NRC
- request, a
conference call was conducted on April 13,
- 1994, to provide information needed to prepare a safety evaluation report regarding resolution of NRC Bulletin 90-01 issues.
Participants in the conversation were Gordon Edison (NRC), Dierdre Spaulding (NRC),
Nelson Tonet (DLC),
and Gary Beatty (DLC).
The following responses were discussed during the call or in subsequent communications.
Ouestion:
t 2ith respect to the Bulletin action item la, describe the specific transmitters' safety functions.
Response
The two transmitters described in our May 1993 response to the Bulletin are PT-1RC-402 and PT-1RC-403.
Refer to Attachment 1 -
Operating Manual 10M-06.1 (pages 60 and 84-86) - for a description of their safety functions.
Ouestion:
With respect to the Bulletin action item ib, describe the specific transmitters' safety functions.
l Resnonse:
Five transmitters were described in our May 1993 response.
Three (FT-1CH-124,
-127, and -130) monitor seal injection flow to the three Reactor Coolant Pumps.
These are used to determine controlled i
leakage per Technical Specification 4.4.6.2.
Refer to Attachment 2 -
Operating Manual 10M-07.1 (pages 2-3) - for a description of their functions.

Response: (Continued)
Another (PT-1SI-940) provides indication of high head SI flow to the RCS.
This indication is used in the emergency operating procedures (EOPs) to confirm that a flow path has been established, but not to obtain precise flow values.
Refer to -
Operating Manual 10M-11.1 (page 1) and 1.53A.1 (pages 8-9) - for a description of its function.
The fifth (PT-1SI-943) provides indication of high head SI flow to the Boron Injection Tank.
This indication is used in the EOPs in a manner similar to FT-1SI-940.
Refer to Attachment 3 - Operating Manual 10M-11.1 (page 1) and 1.53A.1 (pages 8-9) - for a description of its function.
Ouestion:
What dates did DLC begin trending drift data for the seven high pressure transmitters discussed previously?
Response
Trending of calibration data for these transmitters began in June 1990.
This included data from at least the two previous calibration cycles.
Ouestion:
With respect to Bulletin action items le and if, describe how confidence is maintained in the ability to detect failures due to oil loss on an on-going basis.
Response
These transmitters are currently subjected to an enhanced surveillance program consistent with Rosemount guidelines.
Calibration data is evaluated at each calibration and compared to previous results.
There are no current plans to use an alternative method;
- however, future accumulation of data and new information could cause alternatives to be considered.
If such a change is planned, DLC will inform the NRC.
Question:
What method is used to obtain data for use in the enhanced surveillance program?
Response
The zero-drift / span-drift method recommended in Rosemount Technical Bulletin #4 is used at BVPS.
Response to NRC Bulletin 90-01, Supplement 1,
" Loss of Fill-Oil in Transmitters Manufactured by Rosemount" Page 3 Ouestion:
Does DLC apply the acceptance criteria provided by Rosemount l
Technical Bulletin
- 4 to transmitters in the enhanced surveillance program?
Response
Yes.
If you have any questions regarding this matter, please contact Mr. Gary Beatty at (412) 393-5225.
Sincerely,
