BASELINE INSPECTION AND REQUEST FOR INFORMATION; INSPECTION

REPORT 05000263/2021002

Dear Mr. Conboy:

On April 19, 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

April 19, 2021 through April 23, 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 all these documents are accurate and complete to increase the

efficiency of this inspection.

We have discussed the schedule for inspection activities with your staff and understand that our

regulatory contact for this inspection will be Mr. G. Hernandez of your organization. If there are

any questions about this inspection, please contact the lead inspector Matt Domke at

630-829-9562 or Matthew.Domke@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.

T. Conboy -2-

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,

/RA/

A. Information for the In-Office Preparation Week

The following information is requested by March 15, 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. Welding on Code Class 1, 2, or 3 components. 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.

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.

5. 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

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

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

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

component acronyms).

7. 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.

8. 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
