SUBJECT: NOTICE OF VIOLATION
(NRC Inspection Report No. 50-354/95-19)
Dear Mr. Eliason:
This refers to the inspection conducted between November 9, 1995 and December 21, 1995, at the Hope Creek Nuclear Generating Station (HCGS) facility. The purpose of the inspection was to conduct a routine resident safety inspection; assess outage controls; and perform three separate specialist inspector reviews of the inservice inspection program, the outage radiation protection program, and follow-up on the issues of pressure locking and thermal binding of motor operated gate valves. At the conclusion of the inspection, the findings were discussed with Mr. Reddemann of your staff.
The inspector identified three apparent violations of NRC requirements, which were described in the NRC inspection report transmitted with our letter, dated January 30, 1996. Our letter also scheduled a predecisional enforcement conference to be held on March 14, 1996, to discuss the apparent violations associated with inadequate or ineffective corrective actions regarding the operation of safety related equipment, specifically, the safety auxiliaries cooling system and the shutdown cooling system. The NRC also expressed concern regarding previously identified equipment degradation in which corrective actions were not implemented to prevent recurrence, and that these examples of prior ineffective corrective actions may indicate that other previously identified significant problems remain uncorrected.
Mr. Reddemann, Plant Manager, and Mr. Bert Simpson, Vice President, Engineering, responded to our January 30, 1996, letter in a telephone conversation with Mr. Larry Nicholson on February 15, 1996, stating that a predecisional enforcement conference was not warranted. In addition, they stated: (1) that they will complete an evaluation, by February 21, 1996, to determine if any other issues were addressed by engineering for which recommendations were produced, but were not implemented; and (2) they will complete an engineering evaluation of the cyclical fatigue effects of the water hammer on the piping, and that (3) an updated Licensee Event Report (LER) would be sent to NRC by March 8, 1996.
Based on the subject inspection report findings, Licensee Event Report (LER) 95-038-00 - Failure to comply with required action statement upon removal of failed snubber on the RHR Shutdown Cooling Line, LER 95-016-01 - Shutdown Cooling Bypass Event, RHR System B Loop Flow Bypass, LER 95-037-00 - Both Loops of Safety Auxiliary Cooling System (SACS) Inoperable, provided to NRC inspectors during the inspection, in a revised LER 95-038-01, submitted to the NRC in a letter of January 29, 1996, and in a revised LER 95-038-02, submitted to NRC in a letter of March 14, 1996, the NRC determined that violations of NRC requirements occurred. The violations cited in the enclosed Notice of Violation (Notice) and the circumstances surrounding each violation are described in detail in the subject inspection report.
The first violation involved the failure to establish measures to assure that conditions adverse to quality are promptly identified and corrected. In the case of significant conditions adverse to quality, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition. Specifically, over a period of three cycles, you experienced a series of snubber failures as a result of failing to take appropriate corrective action to ameliorate the high forces on the residual heat removal (RHR) piping system that damaged the piping support system. This occurred during the 1992 and 1994 refueling outages. Although corrective actions had been recommended, the corrective actions were not implemented. As a result, overload conditions and additional snubber failures were discovered during the 1995 refueling outage.
A system designed to prevent or mitigate a serious safety event being degraded to the extent that a detailed evaluation would be required to determine its operability is categorized at a Severity Level III. Therefore, this violation has been categorized in accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions" (Enforcement Policy), NUREG-1600; at Severity Level III.
In accordance with the Enforcement Policy, a base civil penalty in the amount of $50,000 is considered for a Severity Level III violation. Because your facility has been the subject of escalated enforcement actions within the last two years, the NRC considered whether credit was warranted for Identification and Corrective Action in accordance with the civil penalty assessment process in Section VI.B.2 of the Enforcement Policy. Credit for identification and corrective actions taken is warranted because you identified the violations and your corrective actions were both prompt and comprehensive. These corrective actions, that were noted in the revised LER 95-038-02, included the following: (1) implementing an enhanced Corrective Action Program (CAP) to communicate management expectations on timely problem identification and resolution with clear definition of roles and responsibilities, (2) fostering a questioning attitude, with training of engineers, including continuation of courses in human error reduction and root cause analysis augmented with a section on water hammer analysis, (3) identifying, evaluating, and tracking under the new CAP, including procedural changes expected to preclude recurrence of void-related water hammer events, and (4) taking actions to evaluate the potential for similar long-standing unresolved performance or reliability issues on safety significant systems at Hope Creek.
LER 95-038-02 also provided a (1) description of the occurrence, and its relationship to similar events, (2) actions taken to investigate and evaluate recent snubber failures, (3) analysis of technical specification noncompliance, (4) analysis of repeat failures, and (5) root cause and safety significance of snubber failures.
Therefore, to encourage prompt identification and comprehensive correction of violations in the future, I have been authorized, after consultation with the Director, Office of Enforcement, not to propose a civil penalty in this case. However, similar violations in the future could result in further escalated enforcement action.
The second violation involved your frequent operation of the safety auxiliary cooling system during the past nine years at temperatures less than the prescribed minimum reflected in the FSAR. The safety auxiliary cooling system was originally designed for a low heat exchanger outlet temperature of 65 degrees F. This was recognized and the effect of this operation was evaluated during startup in 1986 and again in 1991 and found to be acceptable by HCGS engineering. However, you failed to make the appropriate changes to the final safety analysis report. This violation has been classified at Severity Level IV.
You are required to respond to this letter and should follow the instructions specified in the Notice when preparing your response. In your response, you should document the specific actions taken and any additional actions you plan to prevent recurrence. After reviewing your response to this Notice, including your proposed corrective actions and the results of future inspections, the NRC will determine whether further NRC enforcement action is necessary to ensure compliance with NRC regulatory requirements.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response will be placed in the NRC Public Document Room (PDR). To the extent possible, your response should not include any personal privacy, proprietary, or safeguards information so that it can be placed in the PDR without redaction.
The responses directed by this letter and the enclosed Notice are not subject to the clearance procedures of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, Pub. L. No. 96-511.

NOTICE OF VIOLATION
Public Service Electric and Gas Company Docket No. 50-354
Hope Creek Nuclear Generating Station License No. NPF-57
During an NRC inspection conducted between November 9, 1995 and December 21, 1995, violations of NRC requirements were identified. In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed below:
A. 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action" requires that 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. In the case of significant conditions adverse to quality, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition.
Contrary to the above, as of December 15, 1995, the licensee did not establish measures to assure that conditions adverse to quality were promptly identified and corrected. Specifically, the licensee experienced a series of snubber failures over a period of three cycles as a result of failing to take appropriate corrective action to ameliorate high forces on the residual heat removal piping system that damaged the piping support system. During refueling outages in 1992 and 1994, the licensee found failures of the residual heat removal snubbers on the common suction line due to hydraulic overloads on the system. During the 1994 refueling outage the licensee determined several corrective actions which were necessary to ameliorate the high hydraulic loads. However, the corrective actions were not implemented. (01013)
This is a Severity Level III violation (Supplement I).
B. 10 CFR 50.71(e) requires, in part, that each person licensed to operate a nuclear power reactor pursuant to the provisions of 50.21 or 50.22 of this part shall update periodically, as provided in paragraphs (e)(3) and (4) of this section, the final safety analysis report (FSAR) ... The updated FSAR shall be revised to include the effects of: all changes made in the facility or procedures as described in the FSAR; all safety evaluations performed by the licensee either in support of requested license amendments or in support of conclusions that changes did not involve an unreviewed safety question.
Contrary to the above, as of December 15, 1995, the licensee had not updated the FSAR periodically, as provided in paragraphs (e)(3) and (4) of 10 CFR 50.71. Specifically, the safety auxiliary cooling system which was originally designed to operate at a minimum temperature of 65 degrees F, was repeatedly operated for almost a decade at temperatures less than the prescribed minimum reflected in the FSAR. The licensee identified that they were operating outside of the FSAR. HCGS engineering performed an evaluation and found that operating at a temperature below that specified in the FSAR was acceptable. However, the licensee had not made the required changes to the FSAR. This was identified by the licensee during startup in 1986 and 1991. (01014)
This is a Severity Level IV violation (Supplement 1).
Pursuant to the provisions to 10 CFR 2.201, Public Service Electric and Gas 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 I, and a copy to the NRC Resident Inspector at the facility that is the subject of the 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 violation, and (4) the date when full compliance will be achieved. Your response may reference or include previous docketed correspondence, if the correspondence adequately addresses the required response. If an adequate reply is not received within the time specified in this Notice, an order or a 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.
Under the authority of Section 182 of the Act, U.S.C. 2232, this response shall be submitted under oath or affirmation.
Because your response will be placed in the NRC Public Document Room (PDR), to the extent possible, it should not include any personal privacy, proprietary, or safeguards information so that it can be placed in the PDR without redaction. However, if you find it necessary to include such information, you should clearly indicate the specific information that you desire not to be placed in the PDR, and provide the legal basis to support your request for withholding the information from the public.
