MCGUIRE NUCLEAR STATION NOTICE OF VIOLATION 370/81-02-02 B.
10 CFR 50.55a(a)(1) requires systems and components be fabricated and inspected to quality standards consnensurate with the importance of the safety functiori to be performed. ASME Section II Part C SFA-5.9 has been identified as applicable standard for. stainless steel consumable inserts.
Note 1 of Table 1 of SFA-5.9 requires that the total of other elements except iron, identified during the course of routine analysis shall not exceed 0.70 percent.
Contrary to the above, on February 5, 1981, systems and components were not fabricated and inspected to quality standards commensurate with the importance of the safety function to be performed in that 1/8-inch dia-meter type 308 consumable insert material, heat number D3403R308 used in, ASME Class 2, chemical and volume control system Joint No. 2NVP-187-1, had a total of other elements, except iron, identified during routine analysis equal 0.744 percent.

e MCGUIRE NUCLEAR STATION RESPONSE TO IE INSPECTION REPORT 370/81-02-02 1.
Due to a 1975 code change and the results of the naterial test report, the weld material was determined to be acceptable and therefore was not in violation of the applicable code.
2.
N/A 3.
Non-conforming item 12,810 was initiated to document the discrepancy concerning the material test report. The 308 weld insert material, ht. #D3403R308, was determined to be acceptable. Materials are allowed to be furnished in accordance with the effective code at the time of purchase. This material was purchased in 1976. ASME Section II Part C SFA-5.9 Table 1, was revised in the summer 1975 addenda to include the elements molybdenum (0.5%) and copper (0.5%) where previously omitted.
The presence of unlisted elements was limited to < 0.5%.
With this change the unlisted elements now total 0.304% which is below the allow-able 0.5% and therefore acceptable.
4.
A random review of mill test reports for weld materials was made to de-fine this problem as generic or isolated. The results of the review in-dicate that this is an isolated case, as no problems were identified.
In addition, at least one other mill test report was non-conformed for this kind of problem indicating our awareness of the requirements.
5.
All QA personnel who review mill test reports for weld material are aware of this situation and no additional training is required.
