REPORT 05000346/201200
8 (DRS) Dear Mr. Allen: On August 13, 2012 , the U.S. Nuclear Regulatory Commission (NRC) will begin a  
triennial baseline Component Design Bases Inspection (CDBI) at Davis-Besse Nuclear Power Station
.  A team of six inspectors will perform this
3-week inspection.  This inspection will be performed in accordance with NRC Baseline Inspection Procedure (IP) 71111.21.
The CDBI focuses on the design, maintenance, and operation of risk significant components
associated with one or more accident scenario.  The components to be reviewed during thi
s baseline inspection will be identified during the in office preparation week that occurs prior to the first on-site inspection
week.  In addition, operating experience issues, associated with the component samples, will also be selected for review.
The inspection will include three weeks on-site.  The inspection team will consist of six NRC inspectors, of which five will focus on engineering/maintenance
and one on operations.  The current inspection schedule is as follows:
  On-site weeks:
August 13  
- 17, 2012;  August 27  
- 31, 2012; and    September 10 - 14, 2012. The team will be preparing for the inspection, mainly during the week of August 6, 2012, as discussed in the attached enclosure.  A Region III Senior Reactor Analyst may accompany the inspection team during the week of August 13, 2012, to review probabilistic risk assessment data , and assist in identifying risk significant components
and/or specific component functions , which will be reviewed during the inspection.
Experience with previous baseline design inspections of similar depth and length has shown that th is type of inspection is
extremely resource intensive, both for the NRC inspectors
and the licensee staff.  In order to minimize the inspection impact on the site and to ensure a productive inspection for both parties, we have enclosed a request for information needed for the inspection.
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 on
-site portions of the inspection.  Insofar as possible, this information should be provided electronically to the lead inspector.  The information request has been divided into three groups:
 
   B. Allen -2-  The first group lists information necessary for our initial inspection scoping activities.  This information should be provided to the lead inspector no later than July 2, 2012.  By July 13, 2012, the lead inspector will communicate the initial selected set of approximately 20 components.  
   The second group of documents requested is those items needed to support our in
-office preparation activities.  This set of documents, including the calculations associated with the initial selected components, should be provided to the lead inspector at the Regional Office no later than August 1, 2012.  During the in
-office preparation activities, the team 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 to the team onsite on August 13, 2012.
  It is also requested that corrective action documents and/or questions developed during the inspection be provided to the lead inspector as the documents are generated.
The lead inspector for this inspection is Andrew Dunlop.  If you have questions regarding the information requested, please contact Mr. Dunlop at (630) 829-9726 or via e
-mail at andrew.dunlop@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.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice,"

-9760 SUBJECT: DAVIS-BESSE NUCLEAR POWER STATION REQUEST FOR INFORMATION FOR AN NRC TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION (CDBI) INSPECTION

REPORT 05000346/201200

8 (DRS) Dear Mr. Allen: On August 13, 2012 , the U.S. Nuclear Regulatory Commission (NRC) will begin a

triennial baseline Component Design Bases Inspection (CDBI) at Davis-Besse Nuclear Power Station

. A team of six inspectors will perform this

3-week inspection. This inspection will be performed in accordance with NRC Baseline Inspection Procedure (IP) 71111.21.

The CDBI focuses on the design, maintenance, and operation of risk significant components

associated with one or more accident scenario. The components to be reviewed during thi

s baseline inspection will be identified during the in office preparation week that occurs prior to the first on-site inspection

week. In addition, operating experience issues, associated with the component samples, will also be selected for review.

The inspection will include three weeks on-site. The inspection team will consist of six NRC inspectors, of which five will focus on engineering/maintenance

and one on operations. The current inspection schedule is as follows:

On-site weeks:

August 13

- 17, 2012; August 27

- 31, 2012; and September 10 - 14, 2012. The team will be preparing for the inspection, mainly during the week of August 6, 2012, as discussed in the attached enclosure. A Region III Senior Reactor Analyst may accompany the inspection team during the week of August 13, 2012, to review probabilistic risk assessment data , and assist in identifying risk significant components

and/or specific component functions , which will be reviewed during the inspection.

Experience with previous baseline design inspections of similar depth and length has shown that th is type of inspection is

extremely resource intensive, both for the NRC inspectors

and the licensee staff. In order to minimize the inspection impact on the site and to ensure a productive inspection for both parties, we have enclosed a request for information needed for the inspection.

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 on

-site portions of the inspection. Insofar as possible, this information should be provided electronically to the lead inspector. The information request has been divided into three groups:

B. Allen -2- The first group lists information necessary for our initial inspection scoping activities. This information should be provided to the lead inspector no later than July 2, 2012. By July 13, 2012, the lead inspector will communicate the initial selected set of approximately 20 components.

The second group of documents requested is those items needed to support our in

-office preparation activities. This set of documents, including the calculations associated with the initial selected components, should be provided to the lead inspector at the Regional Office no later than August 1, 2012. During the in

-office preparation activities, the team 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 to the team onsite on August 13, 2012.

It is also requested that corrective action documents and/or questions developed during the inspection be provided to the lead inspector as the documents are generated.

The lead inspector for this inspection is Andrew Dunlop. If you have questions regarding the information requested, please contact Mr. Dunlop at (630) 829-9726 or via e

-mail at andrew.dunlop@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.

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), accessible from the NRC Web site at
