BASELINE INSPECTION AND REQUEST FOR INFORMATION

(05000374/2021001)

Dear Mr. Hanson:

On February 22, 2021, the U.S. Nuclear Regulatory Commission (NRC) will begin the Baseline

Inservice Inspection Procedure 71111.08. This onsite inspection is scheduled to be performed

February 22, 2021, through February 26, 2021.

Experience has shown that this inspection is resource intensive both for the NRC inspector and

your staff. In order to minimize the impact to your onsite resources, and to ensure a productive

inspection for both sides, we have enclosed a request for documents needed for this inspection.

These documents have been divided into two groups.

The first group identifies information necessary to ensure that the inspector is adequately

prepared. The second group identifies the information the inspector will need upon arrival at the

site. 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.

We have discussed the schedule for inspection activities with Mr. J. Greenblott, 815-415-3838,

of your organization. If there are any questions about this inspection or the material requested,

please contact the lead inspector John V. Bozga 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.

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 and its enclosure will be available electronically for public inspection in the NRCs

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-rm/adams.html (the Public Electronic

Reading Room).

Sincerely,

/RA/

A. Information for the In-Office Preparation Week

The following information is requested by February 8, 2021, to facilitate the selection of

specific items that will be reviewed during the onsite inspection week. The inspector will

select specific items from the information requested below and request a list of additional

documents needed onsite to your staff. We request that the specific items selected from

the lists be available and ready for review on the first day of inspection. If you have any

questions regarding this information, please call the inspector as soon as possible.

1. For the upcoming outage, a detailed schedule and description of:

a. Non-Destructive Examinations (NDE) planned for Class 1 and 2 Systems and

containment, performed as part of your American Society of Mechanical

Engineers (ASME) Code Inservice Inspection (ISI) Program (include edition and

addenda of Code committed to), and NDE planned for other systems performed

as part of a Risk-Informed ISI Program, or other augmented inspection programs

commitments, as part of an industry initiative. For each weld examination,

include the weld identification number, description of weld (component name),

category, class, type of exam and procedure number, and date of examination;

and

b. welding on Code Class 1, 2, or 3 components.

2. A copy of the NDE procedures and welding procedures used to perform the activities

identified in A.1 (including NDE calibration and flaw characterization/sizing procedures

and Welding Procedure Qualification Records). For ultrasonic examination procedures

qualified in accordance with Appendix VIII, of Section XI of the ASME Code, provide

documentation supporting the procedure qualification (e.g., the Electric Power

Research Institute performance demonstration qualification summary sheets).

3. A copy of ASME Section XI, Code Relief Requests applicable to the examinations

identified in A.1.

4. A list identifying NDE reports (ultrasonic, radiography, magnetic particle, or dye

penetrant), which have identified relevant indications on Code Class 1 and 2 systems

since the beginning of the last refueling outage.

5. List with short description of the welds in Code Class 1 and 2 systems, which have

been fabricated due to component repair/replacement activities since the beginning

of the last refueling outage and identify the system, weld number, and reference

Enclosure

applicable documentation (e.g., NIS-2 forms with definitions of system and

component acronyms).

6. If reactor vessel weld examinations required by the ASME Code are scheduled to

occur during the inspection period, provide a detailed description of the welds to be

examined, and the extent of the planned examination.

7. List with description of ISI related issues such as piping degradation or damage

(e.g., cracks, wall thinning, wear, microbiologically induced corrosion) or errors

identified in piping examinations that have been entered into your corrective action

system since the beginning of the last refueling outage. Also, include a list of

corrective action records associated with foreign material introduced/identified in the
