September 16, 1983 Mr. James P. O'Reilly Serial No. 516 Regional Administrator N0/WDC:cfm Region.II Docket Nos. 50-280 U. S. Nuclear Regulatcry Commission 50-281 101 Marietta_ Street, Suite 2900 License Nos. DPR-32 Atlanta, Georgia-30303 DPR-37
Dear Mr. O'Reilly:
j SUPPLEMENTAL RESPONSE TO IE BULLETIN 80-16 SURRY POWER STATION In NUREG/CR-3047, " Closeout of IE Bulletin 80-16: Potential Mis-application of Rosemount Pressure Transmitters", Surry Power Station is listed with an "open" status. This letter is to closeout this issue for Surry.
In our response to IE Bulletin 80-16, " Potential Misapplication of Rosemount Inc. Models 1151 and 1152 Pressure Transmitters With Either
'A' or 'D' Output Codes", dated July 30, 1980, we stated that Model 1152 pressure transmitters were installed and provided the data requested for each instru:nent.
We further stated that with regard to Surry Power Station Units 1 and 2, no corrective action was planned, that an anal-ysis was ongoing concerning the ' range of process variable measured for
-accident conditions, and that any results.of the analysis showing infor-mation contrary to our findings would be forwarded as a supplement to the original submittal.
While the analysis has sown no information contrary to the original findings,-it has been decided to upgrade the existing instruments either
- through replacement of the instrument or installation of Type "N" re-placement circuit boards. This action has been completed for Unit 2 and will be accomplished in Unit'l during a future outage.
A current status of installed Rosemount Inc. Model 1151 and 1152 pres-sure transmitters (that. do not fall under environmental qualification requirements) with output codes "A" or "D" in safety related systems is attached.
Very truly y urs,
