APPENDIX A NOTICE OF VIOLATION Houston Lighting & Power Company Dockets:
50-498; 50-499 South Texas Project, Units 1 and 2 Licenses: NPF-76; NPF-80 During an NRC inspection conducted on March 5 and 17-19, 1993, 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, the violations are listed below:
A.
Criterion V of 10 CFR 50, Appendix B, states, in part, " Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings...."
Paragraph 4.1.2 of Stat;on Procedure OPG-P03-ZE-0033, "RCS Pressure Boundary Inspection for Boric Acid Leaks," Revision 0 (effective date August 1, 1998) through Revision 4 (effective date February 23, 1993) states, in part, " Form (-2) will be completed for each leak or evidence of leak found...."
Contrary to the above:
1.
Form (-2)s were not completed for five instances cf evidence of leakage that were found during a Unit 2 reactor coolant system walkdown inspection performed on July 14, 1989.
Inspection areas where evidence of leakage was observed included reactor vessel head instrumentation penetrations and pressurizer instrument ports, root valves, and lines.
2.
Fonn (-2)s were not completed for two instances of evidence of leakage at steam generator primary manway covers, that were found during a Unit I reactor coolant system walkdown inspection perfonned on March 14, 1992.
These two examples constitute one Severity Level IV violation (Supplement I) (498;499/9314-01).
B.
Criterion XVI of 10 CFP, 50, Appendix B, states, in part, " Measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected Contrary to the above:
1.
Corrective maintenance was not promptly performed in regard to the identification on March 28, 1991, of evidence of leakage at the Steam Generator IB hot leg primary side manway cover (i.e., boric 9304160171 930413 PDR ADOCK 05000498 G
i acid crystals were observed to be present at bolts 3, 5, and 14).
An outstanding service request, SG-115696, which was intended to correct this condition, remained unplanned as of the February 25, 1993, discovery date of active leakage at this manway.
2.
Elongation measurements in April 1990 of the hot leg and cold leg primary side aanway cover studs for Steam Generators IA and IB resulted in values which exceeded the permissible range stipulated by Department Procedure OPMPO4-RC-0004, " Steam Generator Primary Manway Cover Removal and Reinstallation," Revision 6.
These values were neither identified as a nonconforming condition, nor formally evaluated for determination of required corrective actions.
These two examples constitute one Severity Level IV violation (Supplement I) (498/9314-02).
Pursuant to the provisions of 10 CFR 2.201, Houston Lighting & Power Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region IV, and a copy to the NRC Resident Inspector at the facility that is the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a " Reply to a Notice of Violation" and should include for each violation:
(1) the reason for the violation, or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved.
If an adequate reply is not received within the time specified in this Notice, an order or demand for information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.
