e ENCLOSURE 1 NOTICE OF VIOLATION Entergy Operations, Inc.
Docket No.:
50-458 River Bend Station License No.: NPF-47 EA 98-425 During an NRC inspection conducted on July 20 to August 7,1998, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violation is listed below:
10 CFR 50.59(a)(1) states, in part, that a holder of a license authorizing operation of a production or utilization facility may make changes in the facility as described in the safety analysis report without prior Commission approval unless the proposed change involves an unreviewed safety question.
10 CFR 50.59(a)(2) states, in part, that a change sha'l be deemed to involve an unreviewed safety question if the probability of occurrence or the consequences of an accident or malfunction of equipment important to safety previously analyzed in the safety analysis report may be increased.
Contrary to the above, on July 24,1998, the licensee made a change to the facility as described in the safety analysis report, which created an unreviewed safety question, without obtaining prior Commission approval. Based on a revised calculation, the radiological doses for a loss of coolant accident as reported in Table 15.6-7 of the Updated Safety Analysis Report were increased. Specifically, the exclusion area thyroid dose increased from 32.8 to 37.8 rem, and the low population zone thyroid dose increased from 50.3 to 115.1 rem. Because this change involved an increase in the consequences of an accident previously analyzed in the safety analysis report, it constituted an unreviewed safety question for which prior Commission approval was required.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Entergy Operations, Inc. is hereby required to i
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,611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011, and a copy to the NRC P.esident 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 "Peply to a Notice of Violation" and should include for the violation: (1) the reason for the violation, or, if contested, the basis for disputing the violation or severity level, (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. 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 9901060251 981229 PDR ADOCK 05000458 G
,(-.
2-proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.
If you contest this enforcement action, you should also provide a copy of your response to the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001.
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. If personal privacy or proprietary information is necessary to provide an ecceptable response, then please provide a bracketed copy of your response that identifies the 'Aformation that should be protected and a redacted copy of your response that deletes such information. If you request withholding of such material, you must specifically identify the portions of your response that you seek to have withheld and provide in detail the bases for your claim of withholding (e.g., explain why the disclosure of information will create an unwarranted invasion of personal privacy or provide the information required by 10 CFR 2.790(b) to support a request for withholding confidential commercial or financial information). If safeguards information is necessary to provide an acceptable response, please l
provide the level of protection described in 10 CFR 73.21.
