SUBJECT: WOLF CREEK NUCLEAR OPERATING CORPORATION - NOTIFICATION OF NRC TRIENNIAL HEAT SINK PERFORMANCE INSPECTION (05000482/2016002) AND REQUEST FOR INFORMATION | |||
Dear Mr. Heflin: | |||
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC) staff will conduct a triennial heat sink performance inspection at the Wolf Creek Nuclear Operating Corporation from May 23-27, 2016. The inspection will consist of two reactor | |||
inspectors from the NRC's Region IV office for one week. The inspection will be conducted in | |||
accordance with the NRC Inspection Procedure 71111.07, "Heat Sink Performance." | |||
Experience has shown that this inspection is resource intensive 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. | |||
Please note that the documents are requested to be provided by May 16, 2016. We request that during the onsite inspection week you ensure that copies of analyses, evaluations, or documentation regarding the implementation and maintenance of your heat exchanger program are available. Of specific interest are those documents that establish your heat exchanger program satisfies NRC regulatory requirements and conforms to applicable NRC guidance. Also, appropriate personnel knowledgeable of safety-related heat exchangers should be | |||
available to support the inspector at the site during the inspection. | |||
We have discussed the schedule for this inspection activity with your staff and understand that our regulatory contact for this inspection will be Jason Knust of your licensing organization. If there are any questions about this inspection or the material requested, please contact the | |||
inspectors, Wayne Sifre, by telephone at 817-200-1193 or by e-mail at Wayne.Sifre@nrc.gov, or Chad Stott, by telephone at 817-200-1526 or by e-mail at Chad.Stott@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. | |||
A. Heflin - 2 - 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).
