INSPECTION AND REQUEST FOR INFORMATION; INSPECTION REPORT
05000237/2017004; 05000249/2017004
Dear Mr. Hanson:
On October 30, 2017, the U.S. Nuclear Regulatory Commission (NRC) will begin the Baseline
Inservice Inspection Procedure 71111.08. This onsite inspection is scheduled to be performed
October 30-November 3, 2017.
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. D. Walker, of your organization. If there are any
questions about this inspection or the material requested, please contact the lead inspector
Mr. V. Meghani at 630-829-9751, or via e-mail at Vijay.Meghani@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.

A.
Information for the In-Office Preparation Week:
The following information (electronic copy CD ROM if possible) is requested by
October 23, 2017, 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.
2
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
