SUBJECT: LASALLE COUNTY STATION, UNIT 2 - NOTIFICATION OF NRC
BASELINE INSPECTION AND REQUEST FOR INFORMATION
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

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
