SUBJECT:

MONTICELLO NUCLEAR GENERATING PLANT INFORMATION REQUEST FOR AN NRC BIENNIAL SAFETY SYSTEM DESIGN AND PERFORMANCE CAPABILITY INSPECTION

Dear Mr. Palmisano:

On October 18, 2004, the NRC will begin the required biennial inspection of safety system design and performance capability (SSDPC) at your Monticello Nuclear Generating Plant. This inspection will be performed in accordance with the guidance in NRC baseline inspection procedure 71111.21. The system/components to be reviewed during the SSDI baseline inspection are the high pressure coolant injection and 250 Vdc systems.

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 October 5, 2004. In so far 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 Mr. Andrew Dunlop. If there are any questions about the material requested, or the inspection, please call the lead inspector at (630) 829-9726 or e-mail him at axd7@nrc.gov.

T. Palmisano In accordance with 10 CFR 2.390 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/

Enclosure 1

Initial Document Request I.

Information Requested Expeditiously The following information is requested to be provided as soon as possible, but no later than October 5, 2004. In so far as possible, information should be provided electronically.

Safety System Design and Performance Capability Inspection (SSDI)

The items requested below apply only to the selected systems (high pressure coolant injection and 250 VDC systems):

1.

One copy of the system description, training manual (lesson plan), design basis document, and system health report (as appropriate).

2.

One copy of the normal and abnormal operating procedures.

3.

Six half-size copies of the piping and instrument drawings (Flow Diagrams).

4.

Two half-size copies of the single-line and key electrical diagrams.

5.

PRA information (CDF, RRW, RAW, F-V) for system components, as applicable.

6.

Name and phone numbers of the technical contact, a regulatory contact, and the design and system engineer(s).

7.

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 (active, superceded, historical). 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;

Enclosure 2

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);

8.

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, or change to a component or system function. Please include the number and title, the modification purpose (description), 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.
