Dear Mr. Gipson:

This refers to the routine safety inspection conducted by Messrs. W. J. Kropp.

K. Riemer, R. Twigg, A. Vegel, N. Jackiw, and Ms. M. Gambrioni of this office

from July 27 through September 9, 1993.

The inspection included a review of

i

activities at your Fermi 2 facility.

At the conclusion of the inspection, the

findings were discussed with those members of your staff identified in the

eaclosed report.

Areas examined during the inspection are identified in the report.

Within

I

these areas, the inspection consisted of a selective examination of procedures

and representative records, observations, and interviews with personnel.

Your organization demonstrated excellent teamwork among the various

departments in response to the degraded Modular Power Unit (MPU).

The Shift

Supervisor's questioning attitude concerning dim indicating lights on one of

'

the main control boards resulted in the identification of the degraded MPU.

The inspectors considered the quality assurance audit of the Technical

Specification Surveillance Program, the operator's response to the degraded

,

'

general service water (GSW) system, and engineering's approach to identify a

i

leaking fuel bundle, indicative of good plant performance.

i

i

Conversely, the inspection also identified weaknesses concerning the conduct

s

of an observed firewatch that did little more than hurry from room to room to

J

complete the task without verifying fire barriers were adequate, the less than

adequate actions by operations and engineering to implement a gland seal

,

1

modification or provide compensatory actions to reduce operator challenge

during a reactor trip, and the inadequate assessment by engineering and the

Safety Engineering Group of _Information Notice 87-10 and a related 1993

'

Deviation Event Report.

In this latter case, the problem appears to be

3

repetitive in that a previous inspection report (IR No. 50-341/93010) also

documented a less than adequate assessment of a DER by engineering and safety

engineering.

We request that you respond to these issues describing actions

you have taken or will take to ensure plant tours by firewatches are adequate

to meet management expectations and to improve safety engineering and

3

engineering processing of DERs. We understand that the weaknesses identified

in this inspection report pertaining to the August 13, 1993, reactor trip,

During this inspection, certain of your activities appeared to be in violation

of NRC requirements.

However, the violation was a licensee identified item

Violation will not be issued.
