INSPECTION REPORT NO. 50-373/98009(DRP); 50-374/98009(DRP) AND
l
EXERCISE OF ENFORCEMENT DISCRETION
Dear Mr. Kingsley:
On April 22,1998, the NRC completed an inspection at your LaSalle facility. The enclosed report
presents the results of that inspection.
l
During this 6-week inspection period, overall performance at the LaSalle Station was acceptable,
However, human performance errors continued to occur. This performance resulted in
unauthorized removal of a main turbine temporary alteration, en overflow in the demineralized
water system, an unexpected reactor water cleanup system isolation, performance of control '
room ventilation system hanger work without proper authorization, and inadequate securing of
.
foreign material exclusion control plugs in the reactor core isolation cooling system. Human
~
performance improvements achieved through implementation of extensive actions in the LaSalle
Station Restart Plan are not yet self-sustaining. Continued management focus is warranted in
i
l
this area.
l'
We also note that your staff has been implementing numerous material condition improvements
!
during the current extended shutdown. A number of the resulting system modifications, such as
reactor water cleanup and ventilation system changes, have been quite extensive and exemplify
a management commitment to fixing long-standing equipment problems.
Based on the results of this inspection, the NRC has determined that violations of NRC
j
requirements occurred. The first violation concemed ineffective corrective actions from the
[
June 1996 service water event. Specifically, your staff did not incorporate the structure safety
classification list into the work package preparation process. As a result, maintenance personnel
began work to install fire protection piping supports into a safety related auxiliary building ceiling
using a non-safety related work package. The second violation, involving human error,
concemed performance of control room ventilation system hanger work without proper
,
authorization and contrary to plant administrative procedures.
!
These violations are similar to examples of personnel performance, work contiel and corrective
action problems that existed before the extended shutdown and that your staff is addressing
1
through the LaSalle Station Restart Plan. Accordingly, I have been authorized, after consultation

with the Director, Office of Enforcement, and the Regional Administrator, to exercise
enforcement discretion in accordance with Section Vll.B.2, " Violations identified During Extended
Shutdowns or Work Stoppages," of the " General Statement of Policy and Procedures for NRC
Enforcement Actions" (Enforcement Policy) NUREG-1600, and not issue a Notice of Violation in
this case. Specifically, significant NRC enforcement action has already been imposed against
LaSalle Station for the June 1996 service water sealant intrusion event, the violations were
related to problems which were present prior to the events leading to the shutdown, the
violations would not be classified at a severity level higher than Severity Level 11, the violations
were not willful, and er.iorcement action was not considered necessary to achieve remedial
action. In addition, actions specified in Confirmatory Action Letter Rlll-96-008B effectively
prevent you from restarting LaSalle County Station without implicit NRC approval.
Because of the similarities of the first violation to one of the causes of the June 1996 serv'me
water event, we request that within 30 days of the date of this letter you provide a written
description of your assessment of this recent event.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and the
enclosure will be placed in the NRC Public Document Room.
Sincerely,
