| 5. Independent Inspection Effort (548348) (429028) (429408) (Unit 1)
| |
| The inspector conducted a general inspection of portions of the reactor and auxiliary buildings to observe activities such as housekeeping, material identification and control, and .naterial storag Within the areas inspected no violations or deviations were identified.

| 6. Inservice Inspection - Observation of Work and Work Activities (737530)
| |
| (Unit 1)
| |
| The inspector observed the ISI activities described below to determine whether these activities were being performed-in accordance with regulatory requirements and licensee procedures. The applicable code is the ASME Boiler and Pressure Vessel Code, Section XI,1980 Edition, W80 Addend (See RII Report 50-321/85-35 for a previous-inspection in this area).
| |
| | |
| As.noted in RII Report 50-321/85-35, the first 10 year. interval inspections are to be completed during the current outage. In addition, the licensee is inspecting 100% of the 130 stainless steel welds in the Reactor Recirculation (RECIRC), Residual Heat Removal (RHR), and Reactor Water Cleanup (RWCU) System Also, the licensee is performing Intergranular Stress Corrosion Cracking (IGSCC) mitigation techniques using weld overlays or Induction Heat Stress Improvement (IHSI) on welds not previously mitigated. T.3 observations detailed below pertains to inspections of the stainless steel weld Prior to IHSI, ultrasonic (UT) inspection was performed on an original sample of 22 stainless steel welds. As a result of finding indications, the sample was expanded to 49 welds (23 - 12" RECIRC, 2 - 27" RECIRC, 3 - 28" RECIRC and 21 - 6" RWCU). Seventeen of the 49 welds were found to contain reportable indications (2 - 28" RECIRC, 2 - 22" RECIRC, 9 - 12" RECIRC and 4
| |
| - 6" RWCU). The decision was made to overlay weld 8 (4 - 12" RECIRC and 4-6" RWCU) of the 1 , | |

| During review of the above records, the inspector noted that in some cases Nutech personnel signing traveler inspection steps were the same individuals as the individuals signing the traveler for performing the activities being inspecte This is in violation of paragraph 10.1.2 of the Nutech QA Manual which requires that " Inspection personnel shall be individuals other than those who performed or directly supervised the activity being inspection -- ". Further investigation revealed that the steps were being perfonned by Thompkins-Beckwith (T&B) craft personnel (Nutech's subcontractor) reporting to T&B craft supervision even though the steps were being signed off by Nutech. This is in violation of Nutech QEP 9-4, paragraph 2.5, which requires that subcontractors sign or stamp the traveler indicating that their described operation is completed. This failure to follow procedure is in violation of criterion V of Appendix B to 10 CFR 50 and is identified as item No. 321/86-02-01, Failure to Follow Procedure for Signoff of Traveler Steps for IHS (c) The inspector reviewed personnel training / certification records for personnel involved with the IHSI of the welds listed in paragraphs (a) and (b) above.
