SUBJECT: NRC INSPECTION REPORT 50-483/97-05 AND NOTICE OF VIOLATION

Dear Mr. Randolph:

An NRC inspection was conducted February 10-14 and ?4-28,1997, at your Callaway

Plant reactor facility. The enclosed report presents the scope and results of that

inspection. The overall conclusions of this inspection were discussed with Mr. C. Neslund

and others of your t+aff :iuring a final exit meedng held on June 24,1997.

The inspection identified two violations involving the failure to make a 10 CFR 50.73

report and to report 10 CFR 50.59 safety evaluations for temporary modifications.

Specifically, your staff failed to report that 14 main steam safety valves in Refueling

Outage 7 drifted beyond their Technical Specification setpoint tolerances. With respect to

the 10 CFR 50.59 safety evaluation reporting, your staff failed to recognize that any safety

evaluation, regardless of duration, was required to be reported. These reporting failures

indicate a lack of understanding of the NRC reporting requirements.

The violations arts cited in the enclosed Notice of Violation (Notice) and the circumstances

surrounding these violations are described in detail in the enclosed report. Please note that

you are required to respond to this letter and should follow the instructions specified in the

enclosed Notice when preparing your response. The NRC will use your response, in part,

to determine whether further enforcement action is necessary to ensure compliance with

regulatory requirements.

Based on the results of this inspection, th: .*e apparent violations were also identified and

are being considered for escalated enforcement action in accordance with the " General

Statement of Policy and Procedure for NRC Enforcement Actions" (Enforcement Policy),

NUREG-1600. These apparent violations involved the failure to perform safety evaluations

in accordance with the requirements of 10 C1 ! 50.59. The first two apparent violations

involved the failure to perform a safety evaluation for a change in the method of operation

of the post-accident sampling system and a change to the setpoints of the refueling .

machine. The third apparent violation involved the substitution of manual operation for the j

automatic actuation of the diesel generator building supply fans. This substitution may

have increased the probability of occurrence of a malfunction of equipment important to

safety previously evaluated in the Final Safety Analysis Report and increased the possibility

for a malfunction of a different type than any evaluated previously in the Final Safety

, Analysis Report. Therefore, this substitution potentially constitutes an unreviewed safety

'

question.

, 'In addition, substituting manual actions for automatic operation of the diesel generator

building supply fans made the fans' automatic start function inoperable. Since the fans

were a subsystem of the diesel generators, it appeared that your diesel generators were

rendered inoperable during the times that the fans were in the " pull-to-lock" condition.

3 Depending on the duration that the supply fan switches were in the " pull-to-lock" position

j and the ambient temperature conditions, a violation of Technical Specification requirements

may have occurred. Tnerefore, in your response to this inspection report, we request that

you provide details regarding the specific circumstances in which the diesel generator

building supply fan control switches were in the " pull-to-lock" position.

The circumstances surrounding these apparent violations and the significance of the issues

were discussed with members of your staff at the finalinspection exit meeting on June 24,

1997. As a result, it may not be necessary to conduct a predecisional enforcement

conference in order to enable the NRC to make an enforcement decision. However, a

Notice of Violation is not presently being issued for these inspection findings. Before the

<

NRC makes its enforcement decision, we are providing you an opportunity to either .

'

(1) respond to the apparent violations addressed in thic inspection report within 30 days of

the date of this letter or (2) request a predecisional enforcement conference. Please

contact Mr. Chris A. VanDenburgh at (817) 860-8161 within 7 days of the date of this

letter to notify the NRC of your intended response. J

J

Your response should be clearly marked as a " Response to Apparent Violations in NRC

<

lospection Report 50-483/97-05" and should include for each apparent violation: (1) the

reason for the apparent violation, or, if contested, the basis for disputing the apparent

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

complianco will be achieved. Your response should be submitted under oath or affirmation

and may reference or include previous docketed correspondence if the correspondence

adequately addresses the required response, if an adequate response is not received

within tnv time specified or an extension of time has not been granted by the NRC, the

NRC will proceed with its enforcement decision or schedule a predecisional enforcement

conference.

in addition, please be advised that the number and characterization of apparent violations

described in the enclosed inspection report may change as a result of further NRC review.

You will be advised by separate correspondence of the results of our deliberations on this

matter.
