Dear Mr. Keenan:

SUBJECT: ERRATA FOR DIABLO CANYON POWER PLANT - NRC INSPECTIONREPORT 05000275/2005005 and 05000323/2005005Please insert the enclosure to this letter as replacement for page 42 of NRC Inspection Report05000275/2005005 and 05000323/2005005. A problem identification and resolution crosscutting aspect was incorrectly referenced in Section 4OA2.7 for Noncited Violation 05000275/2005-05-01, Failure to Adequately Assess and Manage Risk Associatedwith Startup Transformer 1-1 Maintenance. Section 1R14 of the report appropriately characterizes the cause of the finding as related to the crosscutting aspect of human performance in that maintenance personnel failed to follow procedures. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and itsenclosure will be available electronically for public inspection in the NRC Public DocumentRoom or from the Publicly Available Records (PARS) component of NRC's documentsystem (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

This LER is closed.4OA5Other .1TI 2515/160 - Pressurizer Penetration Nozzles and Steam Space Piping Connections inU.S. Pressurized Water Reactors a. Inspection ScopeThe inspectors reviewed PG&E's actions regarding the inspection and repair associatedwith Alloy 82/182/600 material that may have been used in pressurizer penetration nozzles, steam space piping connections, heads, and shells. Specifically, the inspectors reviewed PG&E's response to NRC Bulletin 2004-01, "Inspection of Alloy 82/182/600Materials Used in the Fabrication of Pressurizer Penetrations and Steam Space Piping Connections at Pressurized Water Reactors." PG&E documented in their response to the bulletin that no Alloy 82/182/600 material was used in the construction or welds of the Unit 1 pressurizer. PG&E did not commit to, or perform, any nondestruction examination methods for the Unit 1 pressurizer. PG&E did perform a boric acid walkdown of the pressurizer, and the inspectors performed an independent boric acid inspection of pressurizer.The activities required in TI 2515/160 for Diablo Canyon Power Plant Unit 1 have beencompleted. This temporary instruction is closed for Unit 1.
