NOTICE OF VIOLATION Indiana Michigan Power Company D.
C.
Cook Nuclear Plant - Unit 2 Docket No. 50-316 License No.
DPR-74 CFR Part 2, Appendix C'(1988); the following violation was identified:
10 CFR 50, Appendix B, Criterion IX requires that special processes, such as nondestructive testing, be controlled and accomplished using a qualified procedure in accordance with applicable codes and standards.
10 A.
Site radiographic procedure FgP 9.4 invokesSection V of the 1983 ASME Boiler and Pressure Vessel Code including the Summer 1984 Addenda.
ASME Section V, Article I, requires that special techniques when used shall be capable of detecting code rejectable discontinuities.
Articles 2 and 22 requires the direction of the central beam of radiation to be perpendicular to the recording surface (film) when performing radiography.
Contrary to the above, it was disclosed that while performing radiography of a girth weld in steam generator number 21, the source was not positioned perpendicular to the recording surface '(film).
Subsequent radiography performed by NRC inspectors identified Code rejectable defects in the weld that had not been identified by the licensee.
This is a Severity Level IV violation (Supplement I).
As a result of the inspection conducted on September 6-15,
- 1980, and in accordance with the "General Policy and Procedure for NRC Enforcement Actions,"
B.
10 CFR 50, Appendix B, Criterion IX, requires that special processes, such as nondestructive
- testing, be controlled and accomplished using qualified procedures.
Site liquid penetrant procedure FgP 9.2 R12 requires that indications observed in liquid penetrant examinations are recorded and properly dispositioned.
The proper disposition of linear indications that exceed code requirements is repair of the affected area.
Contrary to the above, an NRC re-examination. of the liquid penetrant inspection for weld FW-4-1 on September 9, 1988, revealed two detectable, unacceptable linear indications.
These indications had bot been identified or dispositioned during the licensee's final code liquid penetrant examinations.
This is a Severity Level IV violation (Supplement I).
With respect to Item B;'the inspection showed that actions had been taken to correct the identified violation and to prevent recurrence.
