AND REQUEST FOR INFORMATION; INSPECTION REPORT 05000461/2021004

Dear Mr. Rhoades:

On September 27, 2021, the U.S. Nuclear Regulatory Commission (NRC) will begin the

Baseline Inservice Inspection Procedure 71111.08. This inspection is scheduled to be

performed September 27, 2021, through October 1, 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 your staff and understand that our

regulatory contact for this inspection will be Ms. C. Casarez, of your organization. If there are

any questions about this inspection or the material requested, please contact the lead inspector

Joon Park at 630-829-9715, or via e-mail at joon.park@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.

Information for the In-Office Preparation Week

The following information (electronic copy) is requested by September 13, 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 (NDEs) 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 NDEs 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; and

b.

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

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

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 copy of the 10-year ISI Program showing those required exams scheduled to be

performed this outage, and those which have been completed.

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.

6.

List with short description of the welds in Code Class 1, 2 and 3 systems, which have
