NOTICE OF VIOLATION l Union Electric Company Docket No.: 50-483

Callaway Plant License No.

NPF-30 4

During an NRC inspection conducted on February 10-14 and 24-28,1997, two 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:

l A. 10 CFR 50.73(a)(2)(vii) states, in part, that the licensee shall report any event

, where two independent trains or channels become inoperable in a single system l

designed to mitigate the consequences of an accident.

i Contrary to the above, during Refueling Outage 7, in the spring of 1995, an event involving a single condition that caused independent trains to become inoperable was not reported. This event involved surveillance tests of the main steam safety valves that resulted in 14 out of 20 of these valves failing their as-found setpoint tests with setpoints greater than their Technical Specification setpoint tolerance of i1 percent.

This is a Severity Level IV violation (Supplement 1)(50-483/9705-01). .

l i

B. 10 CFR 50.59(b)(2) states, in part, that the licensee shall submit, as specified in I 10 CFR 50.4, a report containing a brief description of any changes, tests, and l experiments, including a summary of the safety evaluation of each.

Contrary to the above, during the period of June 14,1988, to February 28, 1997, a brief description of changes due to temporary modifications '

(e.g., TM 95-M002) and the associated safety evaluation summaries were not reported to the NRC.

This is a Severity Level IV violation (Supplement I)(50-483/9705-04).

Pursuant to the provisions of 10 CFR 2.201, Union Electri': Company is hereby required to submit a written statement er explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regienal Administrator, Region IV,611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011, 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.

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.

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.
