SUBJECT:
LASALLE INSPECTION REPORT 50-373/99003(DRP); 50-374/99003(DRP)
Dear Mr. Kingsley:
This refers to the inspection conducted April 1 through May 12,1999, at the LaSalle County
Station. The purpose of the inspection was to determine whether activities authorized by the
license were conducted safely and in accordance with NRC requirements. At the conclusion of
the inspection, the findings were discussed with those members of your staff identified in the
enclosed report.
Overall, Unit 1 continued operating safely while considerable station efforts and resources were
devoted to supporting the restart of Unit 2. The Unit 2 restart activities were conducted safely
and plant personnel and equipment generally performed well. However, the NRC noted several
examples of weaknesses in the areas of operator log keeping, corrective action program
implementation, and procedures. The examples noted did not result in events with safety
significant consequences; however, they collectively represented weakened barriers that you
established to ensure sustained, safe operations. The NRC noted improvements and
corrections as the startup activities progressed. You are encouraged to continue your focus in
these areas.
Based on the results of this inspection, the NRC ha determined that two violations of NRC
requirements occurred. The first violation involved two examples of failing to follow procedures.
In one case, operators failed to log suppression pool temperatures as required during reactor
core isolation cooling system testing. In the second example, operators failed to ensure proper
valve configuration associated with the turbine stop valve / turbine control valve fast closure
alarm. The second violation involved an inadequate procedure: an annunciator response
procedure in the main control room associated with Unit 2 drywell oxygen concentration levels
was incorrect and did not apply to the designated alarm. These violations are being treated as
Non-Cited Violations (NCVs), consistent with Appendix C of the Enforcement Policy. The NCVs
are described in the subject inspection report. If you contest the violation or severity level of
these NCVs, you should provide a response within 30 days of the date of this inspection report,
,
with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control
Desk, Washington DC 20555-0001, with copies to the Regional Administrator, Region lil, and
the Director, Office of Enforcement, United States Nuclear Regulatory Commission,
Washington DC 20555-0001.
