SUBJECT:
PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3 - REQUEST
FOR INFORMATION FOR A BIENNIAL PROBLEM IDENTIFICATION AND
RESOLUTION INSPECTION; INSPECTION REPORT 05000277/2025010 AND
Dear David Rhoades:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
Region I staff will conduct a biennial problem identification and resolution inspection at
Peach Bottom Atomic Power Station, Units 2 and 3. Cheryl Khan, a Senior Project Engineer
from the NRCs Region I office, will lead the inspection team. The inspection will be conducted
in accordance with Inspection Procedure 71152, Problem Identification and Resolution, dated
January 1, 2024 (ADAMS Accession No. ML23214A284).
The inspection will assess the effectiveness of your problem identification and resolution
program in identifying, prioritizing, evaluating, and correcting problems, including the use of
operating experience, assessments, and audits. This inspection will also assess your program
for raising concerns under the established safety conscious work environment.
The onsite inspection is scheduled for the week of September 8, 2025.
In order to minimize the inspection impact on the site and to ensure a productive inspection for
both parties, we have enclosed a request for information needed for the inspection. 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. Insofar as possible, this information should be provided electronically to the lead
inspector by August 22, 2025.
If there are any questions about the inspection or the material requested in the enclosure,
please contact the lead inspector at 610-337-5244 or via e-mail at cheryl.khan@nrc.gov.
