Appendix NOTICE OF VIOLATION Commonwealth Edison Company Docket Nos.60-237; $0-249 l Dresden 2 and 3 Licenses No. OPR-19; DPR-25 l

l l As a result of the inspection conducted on December 21, 1984, through

! April 30, 1985, and in accordance with the General Policy and Procedures I

for NRC Enforcement Actions, (10 CFR Part 2, Appendix C), the following violations were identified:

1. 10 CFR 50, Appendix 8, Criterion X, as implemented by Ceco Topical Report CE-1-A,'" Quality Assurance Program for Nuclear Generating Stations," and Ceco Corporate Quality Assurance Manual, Nuclear Generating Stations, Quality Requirements, requires the licensee to establish and execute an inspection program to verify activities affecting quality are in conformance with documented instructions, procedures, and drawings.

l Contrary to the above, piping suspension system hardware r.iodifications that resulted from the Mark 1 program reviews, IE Bulletin 79 14 verifications, and the improvements in configuration made to the main steam safety relief valve discharge piping were not adequately inspected to verify that piping restraint component location, orientation, and configuration were in conformance with design documents (237/84027 01; 249/85013-01).

This is a Severity Level IV violation (Supplement !!).

2. 10 CFR 50, Appendix B, Criterion !!!, as implemented by Ceco Topical Report CE-1-A, " Quality Assurance Program for Nuclear Generating Stations," and Ceco Corporate Quality Assurance Manual, Nuclear Generating Stations, Quality Requirements, requires that design control measures provide for verifying or checking the adequacy of design, such as by the performance of design review.

Contrary to the above, the Nutech piping transient operability analysis performed for the Dresden 2 Low Pressure Coolant Injection System did notgiveproperconsiderationtodesignobjectives,justifythecriteria established and assumptions made, and correctly model the forces experienced during the transient. Nutech's recommendation to replace the failed snubber with a rigid restraint did not consider the potential adverse consequences on the piping. (237/84027 04).

This is a severity Level IV violation (Supplement !!).

l
