SUBJECT: NRC INTEGRATED INSPECTION REPORT NDS. 50-369/98-07 AND

50-370/98-07 AND NOTICE OF VIOLATION

. Dear Mr. Barron:

On July 11. 1998, the Nuclear Regulatory Commission (NRC) completed an

. inspection at your McGuire Nuclear Station. The enclosed report presents the

results of that inspection.

During the six-week period covered by. this inspection, your. conduct of

'

activities at the McGuire facility was generally characterized by safety-

conscious operations, sound engineering and maintenance )ractices, and careful

. radiological work controls. However, two violations of 4RC requirements were

identified and are cited in the enclosed Notice of Violation (hotice). The

circumstances surrounding the violations are described in detail in the

enclosed report. Please note that you are required to r espond 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.

In the area of plant operations we are concerned with an ap)arent oversight

-involving planned reactor coolant system level reductions, w11ch, when further

'

reviewed, were not actually required to perform the removal of the Unit ,1

steam generator nozzle dams. These activities could have resulted in an

increased risk to the shutdown unit by reducing the reactor coolant system

- inventory and extending the duration of the evolutions.

<

In the. area of engineering, we are also concerned with an adverse trend in

emergency diesel generator subcomponent equipment failures. This trend. in

part,:resulted from in6dequate oversight of your diesel generator vendors and

resulted in products or services that were defective or of indeterminate

quality and impacted the reliability of the diesel generators. i

In accordance with 10 CFR 2.790(a) of the NRC's " Rules of Practice " a copy of

this letter. its enclosures. and your response will be placed in the NRC

l Public Document Room (POR).
