Commissions (NRC) Region IV office will perform the baseline inservice inspection at Palo | |||
Verde Unit 1, using NRC Inspection Procedure 71111.08, Inservice Inspection Activities. | |||
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 (Section A of | |||
the enclosure), due by September 26, 2011, 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. Dan Hautaula 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 Jim Melfi at (817) 276-6523 (Jim.Melfi@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 | |||
requesting document displays a currently valid Office of Management and Budget control | |||
number. | |||
