| | ==Dear Mr. Keenan:== |
| | SUBJECT: ERRATA FOR DIABLO CANYON POWER PLANT - NRC INSPECTION REPORT 05000275/2005005 and 05000323/2005005 Please insert the enclosure to this letter as replacement for page 42 of NRC Inspection Report 05000275/2005005 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 Associated with 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 its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS).

| | .7 PI&R Crosscutting Aspects Section 2OS1 identified a problem identification and resolution crosscutting aspect for the failure of radiation protection personnel to post a radiation area and the violation was similar to a violation previously identified in NRC Inspection Report 050000275; 323/2002004. |
| | |
| | Section 4OA2.2 identified a problem identification and resolution crosscutting aspect for the failure of PG&E to adequately evaluate and implement timely corrective actions to ECCS check valve back-leakage. |

| | .1 TI 2515/160 - Pressurizer Penetration Nozzles and Steam Space Piping Connections in U.S. Pressurized Water Reactors a. Inspection Scope The inspectors reviewed PG&Es actions regarding the inspection and repair associated with 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&Es response to NRC Bulletin 2004-01, Inspection of Alloy 82/182/600 Materials 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. |

Dear Mr. Keenan:
SUBJECT: ERRATA FOR DIABLO CANYON POWER PLANT - NRC INSPECTION REPORT 05000275/2005005 and 05000323/2005005 Please insert the enclosure to this letter as replacement for page 42 of NRC Inspection Report 05000275/2005005 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 Associated with 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 its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's 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/

.7 PI&R Crosscutting Aspects Section 2OS1 identified a problem identification and resolution crosscutting aspect for the failure of radiation protection personnel to post a radiation area and the violation was similar to a violation previously identified in NRC Inspection Report 050000275; 323/2002004.
Section 4OA2.2 identified a problem identification and resolution crosscutting aspect for the failure of PG&E to adequately evaluate and implement timely corrective actions to ECCS check valve back-leakage.
4OA3 Event Follow-up (71153)
.1 (Closed) Licensee Event Report 05000323/2005001-00, TS 3.4.10 Not Met During Pressurizer Safety Valve Surveillance Testing Due to Random Lift Spread On January 27, 2005, during scheduled testing of Unit 2 pressurizer safety valves, PG&E identified two of three pressurizer safety valves outside the TS 3.4.10 lift setting of >2460 and <2510 psig.
In NRC Inspection Report 05000275; 323/2005003, an NRC-identified, Green NCV of 10 CFR Part 50, Criterion XVI, was identified for this issue. PG&E documented the problem in Nonconformance Report N0002197. No new information that would change the disposition of this issue was provided in this LER. This LER is closed.
4OA5 Other
.1 TI 2515/160 - Pressurizer Penetration Nozzles and Steam Space Piping Connections in U.S. Pressurized Water Reactors a. Inspection Scope The inspectors reviewed PG&Es actions regarding the inspection and repair associated with 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&Es response to NRC Bulletin 2004-01, Inspection of Alloy 82/182/600 Materials 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 been completed. This temporary instruction is closed for Unit 1.
