SUBJECT: NRC INSPECTION REPORT 50-373/96016(DRP); 50-374/96016(DRP)
Dear Mr. Subalusky:
From October 1 through October 8,1996, the NRC performed a special team inspection at
your LaSalle facility. The enclosed report presents the results of that inspection.
Based on the results of this inspection, the NRC has determined that a violation of NRC
requirements occurred. This violation is cited in the enclosed Notice of Violation (Notice)
and the circumstances surrounding it are described in detail in the subject i.1spection
report.
This report documents two examples of inattention to detail on the part of licensed senior
reactor operators (SROs) while preparing and reviewing work packages for the removal of
safety related equipment from service (OOS program), and an example of a
misinterpretation of a Technical Specification (TS) time clock A non-cited violation of
your TSs resulted from the first example of a poorly prepared and reviewed OOS. This
condition was complicated because your on-duty operators misinterpreted the application
of the TS time clock. As a result of the second OOS problem, you made an unplanned
entry into a TS action statement. This condition was not recognized for several days, and
your compliance with the action statement was fortuitous. The inspectors independently
identified that a portion of your policy for OOSs related to emergency diesel generator
(EDG) work was not formally documented. Collectively, these issues appeared to be
indicative of a need for improved human performance and additional management
attention. Our preliminary assessment was that your corrective actions were effective.
The inspectors concluded that your staff identified a potentially generic concern with WKM
Model 70-13 Air Operated Valve (AOV) actuators as the result of a thorough and proactive
preventive maintenance program. Although the technical resolution to the as-found
condition was diligently pursued, your staff failed to document the non-conformance and
perform an operability determination as specified in your plant procedures. The inspectors
considered this to be a violation of 10 CFR 50, Appendix B, Criterion V, because of the
use of the effected AOVs in the Primary Containment isolation System (PCIS). Our
concern over this level of performance was heightened by th': inspector's identification of
a potential weakness in your program for implementation of established NRC guidance on
