BASELINE INSPECTION AND REQUEST FOR INFORMATION;

INSPECTION REPORT 05000461/2018002

Dear Mr. Hanson:

On May 7, 2018, the U.S. Nuclear Regulatory Commission (NRC) will begin the Baseline

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

May 7, 2018, through May 11, 2018.

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 Mr. Kenneth Pointer, of your organization. If there

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

inspector Mr. Matt Domke at 630-829-9562, or via e-mail at 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.

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 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

A. Information for the In-Office Preparation Week

The following information (electronic copy CD ROM if possible) is requested by

April 16, 2018, 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.

Enclosure

BASELINE INSERVICE INSPECTION DOCUMENT REQUEST

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 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 reactor vessel or reactor coolant system since the beginning of the last

refueling outage.

8. Copy of any Title 10 of the Code of Federal Regulations, Part 21 reports

applicable to your structures, systems, or components within the scope of
