SUBJECT:

DIABLO CANYON POWER PLANT - NOTIFICATION OF AN NRC TRIENNIAL FIRE PROTECTION BASELINE INSPECTION (05000275/2006009 AND 05000323/2006009)

Dear Mr. Rueger:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC),

Region IV staff will conduct a triennial fire protection baseline inspection at the Diablo Canyon Power Plant in January and February of 2006. The inspection team will be comprised of reactor inspectors from the NRC Region IV office and a contractor. The inspection will be conducted in accordance with Inspection Procedure 71111.05T, "Fire Protection (Triennial),"

the NRCs baseline fire protection inspection procedure.

The schedule for the inspection is as follows:

• Information gathering visit: January 4 - 5, 2006

• Onsite inspection: January 23 - 27, 2006 February 13 - 17, 2006 Members of the inspection team will visit the Diablo Canyon Power Plant on January 4 - 5, 2006, to gather information and documents needed to support the inspection, obtain unescorted access, to become familiar with your fire protection program, and to select the fire areas of interest for the inspection. The enclosure to this letter provides a list of documents the team will need to review. You are requested to transmit copies of some of the documents to the NRC Region IV office for team use in preparation for the inspection by the dates listed.

We request that during the onsite inspection weeks, you ensure that copies of analyses, evaluations, or documentation regarding the implementation and maintenance of the fire protection program, including post-fire safe shutdown capability, be readily accessible to the team for their review. Of specific interest are those documents that establish that your fire protection program satisfies NRC regulatory requirements and conforms to applicable NRC and industry fire protection guidance. Also, appropriate personnel knowledgeable of: (1) those plant systems required to achieve and maintain safe shutdown conditions from inside and outside the control room, (2) the electrical aspects of the post-fire safe shutdown analyses,

Pacific Gas and Electric Company (3) reactor plant fire protection systems, and (4) the fire protection program and its implementation should be available to support the team at the site during the inspection.

Your cooperation and support during this inspection will be appreciated. If you have questions concerning this inspection or the inspection team's information or logistical needs, please contact Neil OKeefe at 817-860-8269.

Sincerely,

//RA//

ENCLOSURE Triennial Fire Protection Inspection Documentation Requested Please provide the following documentation prior to the onsite information gathering trip, preferably no later than December 15, 2005. Where practical, please provide copies electronically on compact discs.

1. The current version of your fire protection program and fire hazards analysis.

2. Post-fire safe shutdown analysis and any supporting calculations which demonstrate acceptable plant response.

3. Copies of the licensing basis documents for fire protection (Safety Evaluation Reports, pertinent sections of the Final Safety Analysis Report, exemptions, deviations, letters to/from the NRC regarding fire protection/fire safe shutdown, etc.).

Please provide the following documentation during the onsite information gathering trip January 3-5, 2006. Where practical, please provide copies electronically on compact discs. However, drawings should be provided as paper copies of sufficient size that all details are legible.

Fire protection program implementing procedures (e.g., administrative controls, surveillance testing).

4. Operating procedures used for achieving and maintaining hot and cold shutdown conditions from the control room in the event of a fire outside the control room (III.G.2 areas).

5. Operating procedure(s) used to implement alternative shutdown (III.G.3 areas) capability with or without control room evacuation.

6. Pre-fire plans for the selected fire areas (areas to be selected by the team during the information-gathering trip).

7. A list of equipment used to achieve and maintain hot standby and cold shutdown in the event of a fire (safe shutdown equipment list), and two copies of the piping and instrumentation (flow) diagrams for these systems of a size sufficient to read all details.
