(50.59) BASELINE INSPECTION; INSPECTION REPORT 05000454/2020011;

05000455/2020011

Dear Mr. Hanson:

On August 31, 2020, the U.S. Nuclear Regulatory Commission (NRC) will begin a

50.59 Baseline Inspection at the Byron Station. This inspection will be performed

in accordance with the NRC baseline Inspection Procedure 71111.17T. The onsite portion of

the inspection will take place during the week of August 31, 2020.

Experience has shown that these baseline inspections are 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

documents needed for the inspection. These documents have been divided into three groups:

• The first group of information is necessary to ensure that the inspection team is

adequately prepared for the inspection. This information should be made available via

CD (or alternative) and delivered to the regional office no later than July 20, 2020. The

inspection team will review this information and, by August 3, 2020, will request specific

items that should be provided for review in the regional office by August 17, 2020.

• The second group of requested documents contains additional items that the team

will review, or need access to, during the inspection. Certain documents contained

within Group II (i.e., Item (1)), will be requested for review in the regional office prior

to the inspection by August 17, 2020, as identified above. The remaining documents

should be available by the first day of the onsite inspection, August 31, 2020.

• The third group lists information necessary to aid the inspection team in tracking

issues identified as a result of the inspection. It is requested that this information be

provided to the lead inspector as the information is generated during 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 onsite portions of the inspection.

The lead inspector for this inspection is Mr. John V. Bozga. We understand that our licensing

contact for this inspection is Ms. Zoe Cox of your organization. If there are any questions about

the inspection or the material requested in the enclosure, please contact the lead inspector at

630-829-9613.

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.

This letter and its enclosure will be made available for public inspection and copying at

http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in

accordance with Title 10 of the Code of Federal Regulations, Part 2.390, Public Inspections,

Exemptions, Requests for Withholding.

Sincerely,
