SUBJECT:
NRC INSPECTION REPORT NO. 50 295/97016; 50 304/97016 AND
i
Dear Mr. Mueller:
.
On July 18,1997, the NRC completed an inspection at your Zion 1 and 2 reactor facilities.
The enclosed report presents the results of that inspection.
During this seven week inspection period, your staff's performance was characterized by
several deficiencies in the control of the configuration of plant systems and equipment.
However, neither the operations department personnel nor your staff's use of the
corrective action process identified that an adverse trend had developed. Inspector
identification of material condition deficiencies in the control room called into question the
effectiveness of the previous system walkdowns conducted to assess the material
readiness of Unit 2 for restart.
We are also concerned about three violations of NRC requirements that were identified
during this inspection period. The first violation involves the failure to follow an operating
special procedure for the 2A emergency diesel generator. The second violation pertains to
the failure to provide appropriate procedural guidance for setting the droop potentiometer
prior to loading the common unit emergency diesel generator. The third violation involves
the failure of a quality controlinspection to verify conformance with work instructions for
the common unit emergency diesel generator governor modification. The first two
violations are being cited because they are similar in nature to previously cited violations
involving lack of procedural adequacy and compliance. The third violation is being cited
because it was identified by the NRC,

These violations are cited in the enclosed Notico of Violation, and the circumstances
surrounding the violations are described in detailin 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.
During the resident inspectors' exit meeting for this inspection period on July 30,1997,
we discussed six examples of your staff's failure to maintain control of the configuration
of plant systems and equipment. These examples indicato significant problems in your
equipment configuration control processes. Of particular concern was the failure of your
4
staf f to promptly evaluate these instances and recognize that an adverse trend had
developed. Therefore, please include in your response to the enclosed Notice: (1) your
action to determine the scope of the configuration control problems: (2) your short-term
corrective actions to arrest the adverse trend; and (3) your long term corrective actions to
prevent recurrence, including expected completion dates.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter,
its enclosures, and your response will be placed in the NRC Public Document Room.
We will gladly discuss any questions you have concerning this inspection.
Sincerely,
