Cook Unit 2 NOTICE OF VIOLATION Docket No. 50-316 License No.
DPR-74 An NRC inspection conducted during the period September 6-15, 1988, identified two violations of NRC requirements.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Action", 10 CFR Part 2, Appendix C
(1988),
the particular violations are set forth below.
A.
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.
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 1 requires that special techniques when used shall be equivalent or superior to those described in the Code and they shall be capable of detecting code rejectable discontinuities.
Articles 2 and 22 require 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.
Pursuant to the provisions of 10 CFR 2.201, Indiana
& Michigan Electric is hereby required to submit to this office within 30 days of the date of the letter which transmitted this Notice, a written statement or explanation in reply, including:
1.
the corrective steps which have been taken and the results achieved; 2.
the corrective steps which will be taken to avoid further violations; and 3.
the date when full compliance will be achieved.
Where good cause is shown, consideration will be given to extending this response time.

Appendix A B.
10 CFR 50 Appendix B, Criteria 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 indicat,ions 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 not been identified or dispositioned during the licensee's final code liquid penetrant examinations.
This is a Severity Level IV violation.
Although 10 CFR Section 2.201 requires you to submit to this office within 30 days of your receipt of this notice, a written statement or explanation, we note that this violation was corrected prior to the completion of our inspection and that the corrective actions were reviewed and accepted by the inspector.
Therefore, no response with respect to this matter is required.
