NOTICE OF VIOLATION Northeast Nuclear Energy Company Docket No. 50-336 Waterford, Connecticut License No, DPR-65 l

f: During an NRC inspection conducted on November 4-6,1992, two violations of NRC requirements were identified, in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1992), the violations are listed below:

L A. Title 10, Part 50, Paragraph 50.55a (c) (1) requires that components which are a part c

l of the reactor coolant pressure boundary meet the requirements for Class I components in Section 111 of the American Society of Mechanical Engineers (ASME)

Ibiler and Pressure Vessel Code.

i The " Millstone Unit No. 2 Steam Generator Replacement;" Plant Change Number l 2-036-91, Rev. O, Safety Evaluation, Section 3D, Part 5 states that radiography will be in accordance with ASME Boiler and Pressure Vessel Code, Section 111, 1971 Edition with addenda through summer of 1971.

Appendix IX of this issue of this section of the code, for nondestructive examination methods, under paragraph IX-3340 requires that "the Manufacturer shall record on a-review form the interpretation and disposition of each film."

The procedure for radiography MP-Xil-08: " Radiographic Examination of Weldments and Materials," Revision 0, dated 8/14/91, with procedure change notices 001, dated l

i 5/30/92; 002, dated 9/26/92; and 003, dated 10/27/92; states in Exhibit A, Revision 0, " Instructions for Preparation of Radiographic Reports," Line 15: that

" acceptable indications which were evaluated or comments which concern j interpretation" shall be recorded under the remarks section of the report.

Contrary to the above, on October 12, 1992, the licensee failed to record a linear indication, revealed in a radiograph of weld P-10-C-3-13, per Radiographic Reports 1108 and 1109.

j This is a Severity Level V violation. (Supplement 2) 9212160025 921204 PDR ADOCK 03000336 G pyg

Notice of Violation 2 B. Title 10, Part 50, Paragraph 50.55a (c) (1) requires that components which are a part of the reactor coolant pressure boundary meet the requirements for Class I components in Section III of the ASME Boiler and Pressure Vessel Code.

The " Millstone Unit No.- 2 Steam Generator Replacement;" Plant Change Number 2-036-91, Rev. O, Safety Eva'uation, Section 3D, Part 5 states that radiography will be in accordance with ASME Boiler and Pressure Vessel Code, Section III, 1971 Edition with addenda through summer of 1971.

Appendix IX of this issue of this section of the code, for nondestructive examination methods, under paragraph IX-3324 requires that " objectionable scatter radiation shall be reduced by suitable filtration."

Procedure MP-XII-08: " Radiographic Examination of Weldments and Materials,"

Revision 0, dated 8/14/91, with procedure change notices 001, dated 5/30/92; 002, dated 9/26/92; and 003, dated 10/27/92; states: "If a light density image of the lead-letter B appeats on the film, backscatter is then evident and a new exposure must be made with adequate shielding."

Contrary to the above, on October 12,1992, a light image of a lead letter B appeared on a radiograph of weld P-10-C-3-B and was accepted without correction by the licensee per Radiographic Reports 1108 and 1109.

Tius is a Severity Level V violation. (Supplement 2)

Pursuant to the provisions of 10 CFR 2.201, Northeast Nuclear Energy is hereby required to submit a written statement or explanation to the Regional Administrator, Region I, with a copy to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555, within 30 days of the date of the letter transmitting this Notice of -
