SUBJECT: CALLAWAY PLANT, UNIT 1 - NOTIFICATION OF NRC TRIENNIAL HEAT SINK | |||
PERFORMANCE INSPECTION (05000483/2013005) AND REQUEST FOR | |||
INFORMATION | |||
Dear Mr. Heflin: | |||
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission Region IV | |||
staff will conduct a triennial heat sink performance inspection at your Callaway Plant Unit 1. | |||
The inspection will be comprised of one reactor inspector from the NRC Region IV office. The | |||
inspection will be conducted in accordance with NRC Inspection Procedure 71111.07, "Heat | |||
Sink Performance." | |||
The schedule for the inspection is as follows: | |||
* Onsite Inspection Dates: September 30, 2013 to October 4, 2013 | |||
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 September 23, 2013. 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 that 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 Steve Petzel of your licensing organization. If | |||
there are any questions about this inspection or the material requested, please contact the | |||
inspector, Steven Alferink, by telephone at 817-200-1548 or by e-mail at | |||
Steven.Alferink@nrc.gov. | |||
A.C. Heflin -2- | |||
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. | |||
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 (PARS) component of NRC's document system | |||
(ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading- | |||

Sink Performance."
The schedule for the inspection is as follows:
- Onsite Inspection Dates: September 30, 2013 to October 4, 2013
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 September 23, 2013. We
