AND REQUEST FO

R INFORMATION

INSPECTION REPORT 05000254/2015002; 05000265/2015002 Dear Mr. Hanson

On May 18, 2015, the U.S. Nuclear Regulatory Commission (

NRC) will begin the onsite portion of the Triennial Heat Sink Performance Inspection at your

Quad Cities Nuclear Power Station. 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

April 20, 2015.

By April 27, 2015, the inspector will communicate the initial selected set of approximately

2-3 risk-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

May 4, 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 May 18, 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 the 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

preparation week or during the onsite inspection.

B. Hanson -2- The lead inspector for this inspection is

Michael Jones

. We understand that our regulatory contact for this inspection is Tom Peterson

of your organization

. If there are questions about the material requested, or the inspection, please call

Mr. Jones

at (630) 829

-9745. Please send the information to the following e

-mail address Michael.Jones@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).
