August 1, 2002 Mr. John L. Skolds, President Exelon Nuclear Exelon Generation Company, LLC 4300 Winfield Road Warrenville, IL 60555
SUBJECT:
LASALLE COUNTY NUCLEAR POWER STATION ANNOUNCEMENT OF BASELINE INSPECTION
Dear Mr. Skolds:
On September 9, 2002, the NRC will begin the required biennial safety system design and performance capability inspection at your LaSalle County Nuclear Power Station. This inspection will be performed in accordance with the NRC baseline inspection procedure 71111.21. The system/components to be reviewed during this baseline inspection are the emergency diesel generators and the associated diesel generator cooling water system.
Experience has shown that the baseline design inspections are extremely resource intensive both for the NRC inspectors and the utility staff. In order to minimize the impact that the inspection has on the site and to ensure a productive inspection for both sides, we have enclosed a request for documents needed for the inspection. The documents have been divided into two groups. The first group lists information necessary in order to ensure the inspection team is adequately prepared for the inspection. This information should be available to the Regional Office by no later than August 29, 2002. Insofar as possible, this information should be provided electronically to the lead inspector.
The second group of documents requested are those items which the team will review or need access to during the inspection. It is important that these documents be as complete as possible, in order to minimize the number of documents requested during the preparation week or during the onsite inspection.
The lead inspector for this inspection is Patricia Lougheed. We understand that the regulatory contact for the inspection is Peter Holland of your organization. If there are any questions about the material requested, or the inspection, please call the lead inspector at 630-829-9760 or e-mail her at vpl@nrc.gov.
J. Skolds In accordance with 10 CFR 2.790 of the NRCs "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/

DRPIII DRSIII PLB1 JRK1 DOCUMENT NAME: C:\\ORPCheckout\\FileNET\\ML022140726.wpd To receive a copy of this document, indicate in the box: "C" = Copy without attachment/enclosure "E" = Copy with attachment/enclosure "N" = No copy OFFICE RIII RIII NAME PLougheed:ags DHills DATE 07/30/02 08/01/02 OFFICIAL RECORD COPY
1 Initial Document Request I.
Information Requested Expeditiously The following information is requested to be provided as soon as possible, but no later than August 29, 2002. Insofar as possible, information should be provided electronically.
The items requested below apply only to the selected systems:
1.
One copy of the system description, training manual, design basis document and system health report 2.
One copy of the normal and abnormal operating procedures 3.
Three half-size copies of the piping and instrument drawings (P&IDs) 4.
Two half-size copies of the single-line and key electrical diagrams 5.
Name and phone numbers of the technical contact, a regulatory contact, and the design and system engineer(s) 6.
List of analyses that either support or take credit for operation of the system(s).
For each analysis, besides the number and title, include the purpose of the calculation, the date, a technical contact, and the current status. Clarify any abbreviations or acronyms and give word titles for any numbers (e.g., "residual heat removal inner containment isolation valve" rather than "RH-2301-45B").
In addition to the above, specifically identify (by number) the calculation(s) that address each of the following areas. If a calculation cannot be identified for a particular area, please provide an explanation of why a calculation is not necessary.
Breaker and fuse coordination calculations Diesel loading calculations Instrument uncertainty calculations Room temperature environmental qualification calculations for major equipment Relay setting calculations Setpoint calculations for all technical specification or emergency operation procedure equipment Time delay calculations (for any component incorporating time delay features)
Undervoltage and degraded voltage calculations Voltage drop calculations for all major electrical components (motors, MOVs)
Check valve leakage criteria calculations
2 Design basis (flow rates, levels, pressures, temperatures) confirmation calculations (including NSSS calculations)
Heat exchanger calculations NPSH and total dynamic head calculations Operability determination support calculations Pressure transient/ water hammer evaluations Pump minimum recirculation flow calculations Relief valve sizing calculations Tank over-pressurization calculations 7.
List of all major modifications made to the selected systems since pre-operational testing. Major changes are those that significantly affected the way the system operated, for example, replacement of major components. Please include the number and title, the modification purpose, the date, the status (whether the calculation is active, canceled, superceded or under revision) and a technical contact. Spell out abbreviations, or acronyms and give word titles for any numbers. Note if any of the modifications required prior NRC approval.
8.
List of all major setpoint changes made to the systems since pre-operational testing, unless included as part of Item 7. Major changes are those that significantly affected the way the system operated. Please include the number and title, the component affected, the purpose, the date, and a technical contact.
Spell out abbreviations, or acronyms and give word titles for any numbers.
9.
List of condition reports (corrective action documents) that are in one of the following categories. For each condition report, besides the number and title, clearly designate the status (open/closed), the importance ranking, the date initiated, the date closed (if applicable), the status of corrective actions, and a technical contact. (Note: it is not necessary to provide a separate list for each category)
Any condition report initiated more than two years prior to the inspection that is still open Any condition report (open or closed) initiated in the last two years that required an apparent or root cause analysis (i.e., Category 1 or 2 condition reports)
Any condition report (open or closed) initiated in the last two years that required an operability determination (include determination)
