SUBJECT: PALO VERDE NUCLEAR GENERATING STATION, UNIT 3 - NOTIFICATION | |||
OF INSPECTION (NRC INSPECTION REPORT 05000530/2010005) AND | |||
REQUEST FOR INFORMATION | |||
Dear Mr. Edington: | |||
From October 4 through 15, 2010, reactor inspectors from the U.S. Nuclear Regulatory | |||
Commissions (NRC) Region IV office will perform the baseline inservice inspection at | |||
Palo Verde Nuclear Generating Station (Unit 3), using NRC Inspection Procedure 71111.08, | |||
Inservice Inspection Activities, and Temporary Instruction 2515/172, Reactor Coolant System | |||
Dissimilar Metal Butt Welds. Experience has shown that this inspection is a resource intensive | |||
inspection both for the NRC inspectors and your staff. In order to minimize the impact to your | |||
onsite resources and to ensure a productive inspection, we have enclosed a request for | |||
documents needed for this inspection. These documents have been divided into two groups. | |||
The first group due September 29, 2010, (Section A of the enclosure) identifies information to | |||
be provided prior to the inspection to ensure that the inspectors are adequately prepared. The | |||
second group (Section B of the enclosure) identifies the information the inspectors will need | |||
upon arrival at the site. It is important that all of these documents are up to date and complete | |||
in order to minimize the number of additional documents requested during the preparation | |||
and/or the onsite portions of the inspection. | |||
We have discussed the schedule for these inspection activities with your staff and understand | |||
that our regulatory contact for this inspection will be Mr. Delbert Elkinton of your licensing | |||
organization. Our inspection dates are subject to change based on your updated schedule of | |||
outage activities. If there are any questions about this inspection or the material requested, | |||
please contact the lead inspector, Matthew Young at (817) 276-6545 (matt.young@nrc.gov), or | |||
Theresa Buchanan at (817) 276-6503 (theresa.buchanan@nrc.gov) or Blake Rice at | |||
(817) 276-6563 (blake.rice@nrc.gov). | |||
This letter does not contain new or amended information collection requirements subject to the | |||
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection | |||
requirements were approved by the Office of Management and Budget, Control | |||
Number 3150 0011. The NRC may not conduct or sponsor, and a person is not required to | |||
respond to, a request for information or an information collection requirement unless the | |||
Arizona Public Service Company -2- | |||
requesting document displays a currently valid Office of Management and Budget | |||
control number. | |||
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 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). | |||

Dear Mr. Edington:
From October 4 through 15, 2010, reactor inspectors from the U.S. Nuclear Regulatory
Commissions (NRC) Region IV office will perform the baseline inservice inspection at
Palo Verde Nuclear Generating Station (Unit 3), using NRC Inspection Procedure 71111.08,
Inservice Inspection Activities, and Temporary Instruction 2515/172, Reactor Coolant System
Dissimilar Metal Butt Welds. Experience has shown that this inspection is a resource intensive
inspection both for the NRC inspectors and your staff. In order to minimize the impact to your
onsite resources and to ensure a productive inspection, we have enclosed a request for
documents needed for this inspection. These documents have been divided into two groups.
The first group due September 29, 2010, (Section A of the enclosure) identifies information to
be provided prior to the inspection to ensure that the inspectors are adequately prepared. The
second group (Section B of the enclosure) identifies the information the inspectors will need
upon arrival at the site. It is important that all of these documents are up to date and complete
in order to minimize the number of additional documents requested during the preparation
and/or the onsite portions of the inspection.
We have discussed the schedule for these inspection activities with your staff and understand
that our regulatory contact for this inspection will be Mr. Delbert Elkinton of your licensing
organization. Our inspection dates are subject to change based on your updated schedule of
outage activities. If there are any questions about this inspection or the material requested,
please contact the lead inspector, Matthew Young at (817) 276-6545 (matt.young@nrc.gov), or
Theresa Buchanan at (817) 276-6503 (theresa.buchanan@nrc.gov) or Blake Rice at
(817) 276-6563 (blake.rice@nrc.gov).
This letter does not contain new or amended information collection requirements subject to the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection
requirements were approved by the Office of Management and Budget, Control
Number 3150 0011. The NRC may not conduct or sponsor, and a person is not required to
respond to, a request for information or an information collection requirement unless the
Arizona Public Service Company -2-
requesting document displays a currently valid Office of Management and Budget
control number.
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 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).
