Dear!

This letter refers to allegations that you provided to us on April 19, June 5, and June 22, 1990, alleging: (1) that calibration standards were not traceable to the National Bureau of Standards; (2) that the pressurizer spray valve positioner control wiring drawing was inaccurate; and (3) that the boronometer wiring drawing needed to be corrected after a walkdown.

The first issue was referred to the licensee for their review and followup. A copy of the licensee response is attached for your information. The licensee found that the old standards were traceable to the National Institute of Standards and Technology and as such this part of your allegation appears to be unsubstantiated. We intend no further action in this matter.

Issues (2) and (3) involve drawing inaccuracies that we inspected and discussed in inspection report 50-336/91-08. I have attached the applicable pages of the report for your review.

Your allegations in these cases were substantiated; however, system operation was not affected in either case. Although we intend no further action in these specific matters at this time, we will continue to monitor the licensee *s configuration control program for any programmatic deficiencies.

'Ihankyou for informing us of your concerns.

Sincerely; 02iC!!..il SIGl.'ED By EDYmit0 C. n'Elilit;GER Edward Wenzinger, Chief Reactor Projects Branch 4 Attachments: As stated Infctmalian ic IE;Itccrd :a: 6::c:ed in ac=date r!:!h ti e mdp of information Act.u.emp!!ans_d 7
