SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees
performance by conducting an integrated inspection at Peach Bottom Atomic Power Station,  
Units 2 and 3, in accordance with the Reactor Oversight Process.  The Reactor Oversight
Process is the NRCs program for overseeing the safe operation of commercial nuclear power
reactors.  Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

PLANT STATUS
Unit 2 began the inspection period at rated thermal power (RTP). On March 8, 2022, operators
reduced power to approximately 35 percent RTP in order to enter the drywell to repair a
nitrogen leak on a main steam isolation valve. Following repairs, the unit was returned to RTP
on March 9, 2022. The unit remained at or near RTP for the remainder of the inspection period.
Unit 3 began the inspection period at rated thermal power (RTP). On March 4, 2022, operators
reduced power to approximately 73 percent RTP for a rod pattern adjustment and returned to
RTP the following day. The unit remained at or near RTP for the remainder of the inspection
period.
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in
effect at the beginning of the inspection unless otherwise noted.  Currently approved IPs with
their attached revision histories are located on the public website at http://www.nrc.gov/reading-
rm/doc-collections/insp-manual/inspection-procedure/index.html.  Samples were declared
complete when the IP requirements most appropriate to the inspection activity were met
consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection
Program - Operations Phase.  The inspectors performed activities described in IMC 2515,
Appendix D, Plant Status, conducted routine reviews using IP 71152, Problem Identification
and Resolution, observed risk significant activities, and completed on-site portions of IPs.  The
inspectors reviewed selected procedures and records, observed activities, and interviewed
personnel to assess licensee performance and compliance with Commission rules and
regulations, license conditions, site procedures, and standards.

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licens        ees
performance by conducting an                              integrated inspection at Peach Bottom Atomic Power Station,
Units 2 and 3,                        in accordance with the Reactor Oversight Process.  The Reactor Oversight
Process is the NRCs program for overseeing the safe operation of commercial nuclear power
reactors.  Refer to https://www.nrc.gov/reactors/operating/oversight.html                for more information.

PLANT STATUS
 
Unit 2 began the inspection period at rated thermal power (RTP). On March 8, 2022, operators
reduced power to approximately 35 percent RTP in order to enter the drywell to repair a
nitrogen leak on a main steam isolation valve. Following repairs, the unit was returned to RTP
on March 9, 2022. The unit remained at or near RTP for the remainder of the inspection period.
 
Unit 3 began the inspection period at rated thermal power (RTP). On March 4, 2022, operators
reduced power to approximately 73 percent        RTP for a rod pattern adjustment and returned to
RTP the following day. The unit remained at or near RTP for the remainder of the inspection
period.
 
INSPECTION SCOPES
 
Inspections were conducted using the appropriate portions of the inspection procedures (IPs)              in
effect at the beginning of the inspection unless otherwise noted.  Currently approved IPs with
their attached revision histories are located on the public website at          http://www.nrc.gov/reading -
rm /doc-collections/insp-manual/inspection-                                            procedure/index.html .  Samples were declared
complete when the IP requirements most appropriate to the inspection activity were met
consistent with Inspection Manual Chapter (IMC) 2515, Light    -Water Reactor Inspection
Program - Operations Phase.      The inspectors performed activities described in IMC 2515,
Appendix D, Plant Status, conducted routine reviews using IP 71152, Problem Identification

inspectors reviewed selected procedures and records, observed activities, and interviewed
personnel to assess licensee performance and compliance with Commission rules and
regulat ions, license conditions, site procedures, and standards      .

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees

performance by conducting an integrated inspection at Peach Bottom Atomic Power Station,

Units 2 and 3, in accordance with the Reactor Oversight Process. The Reactor Oversight

Process is the NRCs program for overseeing the safe operation of commercial nuclear power

reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

PLANT STATUS

Unit 2 began the inspection period at rated thermal power (RTP). On March 8, 2022, operators

reduced power to approximately 35 percent RTP in order to enter the drywell to repair a

nitrogen leak on a main steam isolation valve. Following repairs, the unit was returned to RTP

on March 9, 2022. The unit remained at or near RTP for the remainder of the inspection period.

Unit 3 began the inspection period at rated thermal power (RTP). On March 4, 2022, operators

reduced power to approximately 73 percent RTP for a rod pattern adjustment and returned to

RTP the following day. The unit remained at or near RTP for the remainder of the inspection

period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in

effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with

their attached revision histories are located on the public website at http://www.nrc.gov/reading-

rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared

complete when the IP requirements most appropriate to the inspection activity were met

consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection

Program - Operations Phase. The inspectors performed activities described in IMC 2515,

Appendix D, Plant Status, conducted routine reviews using IP 71152, Problem Identification

and Resolution, observed risk significant activities, and completed on-site portions of IPs. The

inspectors reviewed selected procedures and records, observed activities, and interviewed

personnel to assess licensee performance and compliance with Commission rules and

regulations, license conditions, site procedures, and standards.
