have been identified and corrected in a timelier fashion.
Some of the above results appeared to be in violation of NRC requirements, as
specified in the enclosed Notice of Violation (Notice). The violations are of
concern because of the importance of performing correct post modification
testing and having adequate acceptance criteria defined in surveillance
procedures.
A previous problem with the adequacy of a surveillance procedure
was documented in LER 341/93006.
You are required to respond to this letter and should follow the instructions
specified in the enclosed Notice when preparing your response,
in your
response, you should document the specific actions taken and a..y additional
actions you plan to prevent recurrence.
In addition, we request that you
respond to the specific weaknesses discussed above.
Your response should
describe what actions you have taken or plan to take to improve performance
in these areas.
After reviewing your response to this Notice, including your
proposed corrective actions and the results of future inspections, the NRC
will determine whether further NRC enforcement action is necessary to ensure
compliance with NRC regulatory requirements.
In addition to the above response, we understand that by September 1, 1993,
you will provide a description of how your modification process will be
improved to ensure that components added via the modification process will
be incorporated into the preventive maintenance program.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of
this letter and the enclosed inspection report will be placed in the NRC
Public Document Room.
The responses directed by this letter and the accompanying Notice ;ra not

Dear Mr. Gipson:

SUBJECT: NOTICE OF VIOLATION (NRC INSPECTION REPORT NO. 50-341/93010(DRP))
This refers to the routine safety inspection conducted by Messrs. W. J. Kropp,
,
K. Riemer, and R. Twigg of this office from May 4 through June 22, 1993.
The
inspection included a review of 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 enclosed report.
Areas examined during the inspection are identified in the report.
Within
these areas, the inspection consisted of a selective examination of procedures
M
and representative records, observations, and interviews with personnel.
The results of this inspection indicated strengths in the development of an
outage checklist and the use of critiques for system outages at power; in
improvementn in plant lighting; and in improvements in the material condition
of Combusti,n Turbine CTG 11-1.
These were indicative of aggressive actions
to improve performance.
However, the inspection also identified the following weaknesses: (1) post
modification testing requirements specified in engineering design packages
were not perforced when the "at risk" potential design change process was
utilized; (2) acceptance criteria for the performance of the surveillance
procedure for the Standby Liquid Control (SLC) system did not clearly specify
all required acceptance criteria to meet the technical specification
requirements; (3) actions taken by Operations Department personnel in
establishing the proper system lineup to support work on the SLC were not
implemented as required by your written work instructions; (4) weaknesses in
work planning and preparation may have lead to a safety system unnecessarily
being removed from service and improper documentation of step completions; and
(5) corrective maintenance work request had not been issued for a bent needle
'
on the HPCI discharge pressure gage until identified by the NRC during a plant
tour.
In this latter case, had the corrective maintenance request concerning
