1 5 00 2 Dear Mr. Hanson:
On April 20, 2015, the U.S. Nuclear Regulatory Commission (NRC) will begin the onsite portion of the
Triennial Heat Sink Performance Inspection at your LaSalle County Station, Units 1 and 2. This inspection will be performed in accordance with NRC Baseline Inspection Procedure (IP) 71111.07.
In order to minimize the impact that the inspection has on the site
, and to ensure a productive inspection, we have enclosed a request for documents needed for the inspection. The
documents have been divided into three groups
- The first group lists information necessary for our initial inspection scoping activities. This information should be available to the lead inspector no later than March 25, 2015. By April 1, 2015, the inspector will communicate the initial selected set of approximately
1-2 ris k-significant heat exchangers.
The second group
is needed to support our in
-office preparation activities. This set of documents, including the calculations associated with the selected heat exchangers, should
be available at the Regional Office no later than April 10, 2015. This information should be separated for each selected component, especially if provided electronically (e.g., folder with
component name that includes calculations, condition reports, maintenance history, etc
.). During the in
-office preparation activities, the inspector may identify additional information needed to support the inspection.
The last group includes the additional information above as well as plant
-specific reference material. This information should be available onsite to the inspector
on April 20, 2015. It is also requested that corrective action documents and/or questions developed during the inspection be provided to
the inspector as the documents are generated.
All requested documents are to be for the time period from the onsite inspection period back to documents that were provided in response to the previous
Heat Sink Performance
Inspection. If no activities were
accomplished
in that time period, then the request applies to the last applicable document in the previous time period.
It is important that these documents be as complete as possible, in order to minimize the number of documents requested during the
pr eparation week or during the onsite inspection.
B. Hanson -2- The lead inspector for this inspection is Mr. Andrew Dunlop. We understand that our regulatory contact for this inspection is Mr. Larry Blunk
of your organization. If there are questions about the material requested, or the inspection, please call Mr. Andrew Dunlop
at (630) 829
-9726. Please send the information to the following e
-mail address
- Andrew.Dunlop@nrc.gov
. A hard-copy with the required information is also an acceptable option.
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 Title 10 of the Code of Federal Regulations
(10 CFR) 2.390, "Public Inspections, Exemptions, Requests for Withholding," of the NRC's "Rules of Practice," a copy
of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC's Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide
Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading

b. Copies of the documents that demonstrate that flow balance testing was performed during the last
3 years. If the last flow test was performed longer than 3 years, then provide the last flow test.
c. Copies of the documents that demonstrate that flow balance testing will continue to be periodically done in the future.
d. Copies of procedures used to monitor interface valves between the safety
related section of the service water system and the non
-safety related section , and the associated results. The requested documents are to be fo
r the time period from the onsite inspection period back to the documents that were provided in response to the previous Heat Sink Performance Inspection
