SUBJECT: PEACH BOTTOM ATOMIC POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000277/2012005 AND 05000278/2012005
Dear Mr. Pacilio:
On December 31, 2012, the U. S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3. The enclosed integrated inspection report documents the inspection results, which were discussed on January 18, 2013, with Mr. Michael Massaro, Site Vice President, and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of this inspection, no findings were identified. However, three licensee-identified violations, which were determined to be of very low safety significance, are listed in this report. However, because of the very low safety significance, and because they are entered into your corrective action program (CAP), the NRC is treating these findings as non-cited violations (NCVs), consistent with Section 2.3.2 of the NRC Enforcement Policy. If you contest any NCVs in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the PBAPS.
In accordance with Title 10 of the Code of Federal Regulations (10 CFR), Section 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRC's document system (ADAMS). ADAMS is accessible from the NRC Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

DETAILS Summary of Plant Status
Unit 2 began the inspection period shutdown for the 19th refueling outage (RFO) (P2R19). On October 17, 2012, the reactor mode switch was placed in start-up and the unit was
synchronized to the grid on October 19. On October 21, the unit was returned to 100 percent
rated thermal power (RTP). Unit 2 remained at RTP until the end of the inspection period, except for brief periods to support planned testing and control rod pattern adjustments.
Unit 3 began the inspection period at 100 percent RTP. On November 10, operators reduced
power to approximately 70 percent to perform main turbine control valve trouble-shooting and repair, and a control rod pattern adjustment. The unit was returned to 100 percent
RTP through the end of the inspection period, except for brief periods to support planned testing and control rod pattern adjustments.

- OD [[]]
CM descriptions. The inspectors verified that channel calibration and functional tests were performed
consistent with radiological effluent
RETS)/ODCM. The inspectors verified that (a) Exelon calibrated its monitors with National Institute of Standards and Technology
(NIST) traceable sources, (b) if a primary calibration, it adequately represents the plant nuclide mix, (c) if a secondary calibration, it verifies the primary calibration, and (d) the channel calibrations encompass the instrument's alarm set points. The inspectors verified that effluent monitor alarm set points were established as
provided in the
- OD [[]]
CM and station procedures. For changes to effluent monitor set points, the inspectors evaluated the basis for changes to ensure that an adequate justification exists. The inspectors selected laboratory analytical instruments used for radiological analyses
and verified that daily performance checks and calibration data indicated that the
frequency of the calibrations was adequate and there were no indications of degraded instrument performance. As part of the problem identification and resolution (PI&R) review, the inspectors verified
that appropriate corrective actions were implemented in response to indications of
degraded instrument performance. The inspectors selected the drywell/containment high-range monitor and reviewed the
calibration documentation since the last inspection. The inspectors verified that an electronic calibration was completed for all range decades above 10 rem/hour and that at least one decade at or below 10 rem/hour was calibrated using an appropriate radiation source. The inspectors determined that the calibration acceptance criteria were reasonable,
accounting for the large measuring range and the intended purpose of the instruments. The inspectors reviewed Exelon's capability to collect high-range, post-accident iodine effluent samples. The inspectors observed electronic and radiation calibration of these instruments to
verify conformity with Exelon's calibration and test protocols. The inspectors reviewed Exelon's 10 CFR Part 61, "Licensing Requirements for Land
Disposal of Radioactive Waste," source term to determine if the calibration sources used
were representative of the types and energies of radiation encountered in the plant. The inspectors verified that problems associated with radiation monitoring instrumentation were being identified by Exelon personnel at an appropriate threshold and were properly addressed for resolution in Exelon's CAP.
Enclosure b. Findings No findings were identified. 2RS6 Radioactive Gaseous and Liquid Effluent Treatment (71124.06 - 1 sample) a. Inspection Scope During the week of December 3 - 7, 2012, the inspectors: (1) ensured that the gaseous and liquid effluent processing systems were maintained so that radiological discharges are properly mitigated, monitored, and evaluated with regard to public exposure;
(2) ensured that abnormal radioactive gaseous or liquid discharges and conditions, when
effluent radiation monitors were OOS, were controlled in accordance with applicable
regulatory requirements and Exelon procedures; (3) verified that Exelon's quality control program ensured that the radioactive effluent sampling and analysis requirements were satisfied so that discharges of radioactive materials were adequately quantified and
evaluated; and (4) verified the adequacy of public dose calculations and projections
resulting from radioactive effluent discharges. The inspectors used the requirements in
CFR Part 50 Appendix A - Criterion 60,
"Control of Release of Radioactivity to the Environment," and Criterion 64, "Monitoring Radioactive Releases;
- 10 CFR 50 Appendix I Numerical Guides for Design Objectives and Limiting Conditions for Operations to Meet the Criterion "

CM Guidance:
Standard Radiological Effluent Control, as well as applicable Industry standards, and
Exelon procedures required by
ODCM as criteria for determining compliance. The inspectors reviewed the Annual Radiological Effluent Release Reports issued since the last inspection. The inspectors determined that the reports were submitted as
required by the
TSs. The inspectors identified radioactive effluent monitor operability issues reported by Exelon as provided in effluent release reports, and
determined that the issues were entered into the
ODCM made by Exelon since the last inspection. The inspectors determined that Exelon had not identified any non-
radioactive systems that had become contaminated as disclosed either through an event report or as documented in the
- OD [[]]
CM since the last inspection. The inspectors reviewed reported groundwater monitoring results, and changes to Exelon's written program for identifying and controlling contaminated spills/leaks to
groundwater. The inspectors reviewed licensee event reports (LERs) and/or special reports related to
the effluent program issued since the previous inspection. The inspectors identified no additional focus areas for the inspection based on the scope/breadth of problems described in these reports. The inspectors reviewed effluent program implementing
procedures, particularly those associated with effluent sampling, effluent monitor set
point determinations and dose calculations.
Enclosure The inspectors performed walkdowns of selected components of the gaseous and liquid discharge systems to verify that equipment configuration and flow paths align with the documents reviewed and assess equipment material condition. For equipment or areas associated with the systems selected above, that were not readily accessible due to radiological conditions, the inspectors reviewed Exelon's material condition surveillance
records. The inspectors walked down those filtered ventilation systems whose test
results were reviewed during the inspection. The inspectors verified that there were no
conditions, such as degraded high efficiency particulate air (HEPA)/charcoal banks, improper alignment, or system installation issues that would impact the performance, or the effluent monitoring capability, of the effluent system. The inspectors determined that Exelon had not made any significant changes to their
effluent release points. The inspectors observed the routine processing and discharge of effluents (including
sample collection and analysis). The inspectors verified that appropriate effluent
treatment equipment was being used and that radioactive liquid waste was being
processed and discharged in accordance with procedure requirements and aligns with
discharge permits. The inspectors selected effluent sampling activities and verified that adequate controls
had been implemented to ensure representative samples were obtained. The inspectors
determined that the facility was not routinely relying on the use of compensatory
sampling in lieu of adequate system maintenance, based on the frequency of compensatory sampling since the last inspection. The inspectors reviewed the results of the inter-laboratory comparison program to verify
the quality of the radioactive effluent sample analyses. The inspectors verified that the
inter-laboratory comparison program included hard-to-detect isotopes as appropriate. The inspectors reviewed the methodology that Exelon uses to determine the effluent
stack and vent flow rates. The inspectors verified that the flow rates are consistent with
- UFS [[]]
AR values, and that differences between assumed and actual stack
and vent flow rates do not affect the results of the projected public doses. The inspectors verified that surveillance test results since the previous inspection for
HEPA and charcoal filtration) met TS acceptance criteria. The inspectors reviewed radioactive liquid and gaseous waste discharge permits. The inspectors verified that the projected doses to members of the public were accurate and based on representative samples of the discharge path. The inspectors evaluated the
methods used to determine the isotopes that are included in the source term to ensure
all applicable radionuclides were included, within delectability standards. The inspectors
reviewed the current 10 CFR Part 61 analyses to ensure hard-to-detect radionuclides
were included in the source term. The inspectors reviewed changes in
- PBA [[]]
PS's offsite dose calculations since the last
inspection. The inspectors verified that the changes are consistent with the
- OD [[]]
CM and
Regulatory Guide 1.109. The inspectors reviewed meteorological dispersion and
deposition factors used in the
- OD [[]]
CM and effluent dose calculations to ensure appropriate factors were being used for public dose calculations. The inspectors
Enclosure reviewed the latest land use census and verified that changes have been factored into the dose calculations. The inspectors verified that Exelon was continuing to implement the voluntary Nuclear
Energy Institute (NEI)/Industry Groundwater Protection Initiative (GPI) since the last
inspection. The inspectors reviewed monitoring results of the GPI to determine if Exelon
had implemented its program as intended, and to identify any anomalous results. No
anomalous results were identified. The inspectors reviewed identified leakage or spill events and entries made into
CFR 50.75 (g) records. The inspectors reviewed evaluations of leaks or spills, and
reviewed any remediation actions taken for effectiveness. The inspectors reviewed
onsite contamination events involving contamination of groundwater. The inspectors verified that on-site groundwater sample results and a description of any
significant on-site leaks/spills into groundwater for each calendar year were documented in the Annual Radiological Environmental Operating Report for
TS (RETS). The inspectors verified that problems associated with the effluent monitoring and control program were being identified by Exelon at an appropriate threshold and were properly
addressed for resolution in Exelon's CAP.

Routine Review of PI&R Activities a. Inspection Scope
As required by Inspection Procedure (IP) 71152, "Promblem Identification and
Resolution," the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that
CAP at an
appropriate threshold, gave adequate attention to timely corrective actions, and identified and addressed adverse trends. In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the
CR screening meetings.
Enclosure b. Findings and Observations No findings were identified.
.2 Semi-Annual Review to Identify Trends (1 Semi-annual Trend sample)
a. Inspection Scope The inspectors performed a semi-annual review of site issues, as required by Inspection
Procedure 71152, "Problem Identification and Resolution," to identify trends that might
indicate the existence of more significant safety issues. In this review, the inspectors
included repetitive or closely-related issues that may have been documented by Exelon outside of the corrective action program, such as trend reports, performance indicators, major equipment problem lists, system health reports, maintenance rule assessments, and maintenance or corrective action program backlogs. The inspectors also reviewed
Exelon's corrective action program database to assess CRs written in various subject
areas (equipment problems, human performance issues, etc.), as well as individual
issues identified during the

PS-4121A) was found at a trip setting of 495 psig and the 'B' pressure sensing instrument (PS-4121B) was found at
a trip setting of 493 psig. The cause of this event is due to instrument drift. This
occurrence is reportable as a result of a common cause inoperability that resulted in two
instruments drifting low outside of the TS allowable value. The 'A' and 'B' instruments
were replaced and calibrated to within acceptable limits. There was no actual safety consequences associated with this event. If an operational transient would have occurred during power operations, the 'C' and 'D' instrument channels were operable

a. Inspection Scope The objective of this TI is to assess groundwater protection programs to determine
whether licensees' have implemented the program elements in their groundwater protection programs that were identified as incomplete in
- TI 2515/173. During December 3 - 7, 2012, the inspectors reviewed previously identified incomplete program elements within Exelon's Industry
GPI. The incomplete program elements
previously identified (NRC Inspection Report 05000277/2010004: 05000278/2010004) were: 1.
- GPI Objective 1.2 g - At the time of the inspection, a specific frequency had been established for periodic reviews of
SSCs and work practices. However, the frequency had not yet been placed in a procedure. This matter was identified in a
self-assessment and placed in the
AR924237924237 2. GPI Objective 1.3 f - At the time of the inspection, Exelon had established a program for the preventative maintenance of groundwater wells. However, the program had not yet been incorporated into all applicable implementing procedures. Exelon
placed this issue into its
AR924237924237 3. GPI Objective 1.4 a.- At the time of the inspection, written procedures had not been established outlining the decision making process for remediation of leaks or spills or other instances of inadvertent releases, including consideration of migration
pathways. Exelon identified this issue during an assessment of
CAP. (AR924237924237 4. GPI Objective 1.4 c.- At the time of the inspection, an evaluation had not been performed and documented on the decommissioning impacts resulting from remediation activities or the absence thereof (e.g., do licensee procedures include a
decision making process to evaluate prompt remediation or delayed remediation and its impact on decommissioning). Exelon identified this issue during an assessment of
- GPI Objective 1.5 - Exelon developed program procedures to establish a record keeping program to meet the requirements of 10
CFR 50.75(g) and developed an
historical spill/leak list. However, Exelon identified, during a June 2010 audit, that
the individual record files did not reflect some information contained in station files.
Exelon initiated a review to ensure all appropriate information, consistent with criteria in

b. Findings
No findings were identified. .6 Post-Approval Site Inspection for License Renewal (IP 71003)
a. Inspection Scope On a sampling basis, the inspectors verified that Exelon had completed the necessary actions to comply with the license conditions that are a part of the renewed operating
Enclosure license, and had implemented the aging management programs included in the
- NRC staff's license renewal safety evaluation report. The inspectors verified that Exelon followed the guidance in
NEI 99-04 for the license renewal commitment change process, including the elimination of commitments, and properly evaluated, and reported where
necessary, changes to license renewal commitments listed in the
- UFS [[]]
AR in accordance
with 10 CFR 50.59.
This inspection verified, by observation, selected: License conditions added as part of the
- PBAPS renewed license License renewal commitments and selected aging management programs License renewal commitments revised after the renewed license was granted, were implemented in accordance with Title 10 of the Code of Federal Regulations (
CFR) Part 54, "Requirements for the Renewal of Operating Licenses for Nuclear Power
Plants"
b. Findings and Observations No findings were identified.
The inspectors concluded that Exelon's actions regarding the commitments described
below were complete and met regulatory expectations as reflected in the NRC staff's
safety evaluation report. Commitments and Aging Management Programs Flow-Accelerated Corrosion Program The inspectors observed ultrasonic measurements taken of the standby liquid control tank suction piping (WO CO241697). The piping was examined 12-inches on either side
of the weld between valve HV-2-11-11 and the tee downstream of the weld location.
The examination was implemented in accordance with procedure
AA-335-045, "Manual Ultrasonic Requirements for Non-PDI Examinations," Revision 2. This evolution was evidence of the implementation of the aging management program proposed in the original Exelon license renewal application Section B.1.1, "Flow-Accelerated Corrosion
Program," which was codified by the renewed license condition requiring renewal related aging management programs entered into the
- UFS [[]]
AR.
Commitment 6 - Inspection of Outer Sluice Gates Commitment 6, in the renewal Safety Evaluation Report, Appendix A, requires Exelon to
perform an inspection of outer sluice gates in the circulating water pump structure. This
commitment encompassed by the
- UFS [[]]
AR, Section A.2.5, "Outdoor, Buried, and
Submerged Component Inspection Activities," and must be performed prior to period of extended operation. This commitment was generated in the applicant's response to the
RAI) 3.5-3, in a letter dated May 21,
2002. This commitment was tracked by Exelon as Commitment T04329, which was
noted on the work order implementing the inspection.
The outer sluice gates work in conjunction with the ESW system to support safe shutdown following a loss of the normal heat sink. As a consequence of the safe shutdown function of the structural steel sluice gates, Exelon identified the structural
Enclosure steel sluice gates and embedment, in Table 2.4-11 of the original application to renew their license, as a long-lived structural component of the circulating water pump structure that is subject to an aging management review. The sluice gates and embedment have the intended function of maintaining the pressure boundary when the emergency cooling
water system is called upon to operate. During the Unit 2 outage, when desilting
operations are implemented at the intakes, the circulating water pump structure, the
- HP [[]]
SW cross-tie sluice gate, and the Unit 2 'A' and
'B' sluice gates, were visually examined for a significant loss of material. The inspectors observed the diving and inspection activities implemented as part of the desilting operations, interviewed the operation manager, and reviewed the recurring task activity
(WO NBR R1178278).
Commitment 8 - Reactor Pressure Vessel Top Guide Inspection Commitment 8, in the renewal Safety Evaluation Report, Appendix A, requires that
Exelon perform an inspection of the reactor pressure vessel top guide prior to the period
of extended operation. The commitment is part of the aging management program as
described in the
NRC inspectors observed the implementation of remote visual examinations of the reactor pressure vessel top guide and reviewed the
ongoing video interrogation of the guides by trained and knowledgeable vendors.
MR Structure Monitoring Program The inspectors observed the implementation of a visual examination of the structures
associated with the 'B' and 'D' core spray rooms. This inspection was part of aging
management program B1.16, "MR Structure Monitoring Program." The inspectors noted that the check list used during the visual inspection included all the essential elements of a maintenance monitoring program. Such items as corrosion, missing or degraded
grout, and crack welds in structural steel components were included in the checklist.
Masonry walls, although limited, were visual inspected for cracked joints, deteriorated
penetrations, and missing or broken blocks. Component supports were checked for missing or loose bolts and cracked welds.
4OA6 Meetings, Including Exit Quarterly Resident Exit Meeting Summary On January 18, 2013, the resident inspectors presented the inspection results to
Mr. Michael Massaro, Site Vice President, and other
- PBA [[]]
PS staff, who acknowledged
the findings. Mr.
- USNRC , Region 1, Division of Reactor Projects, Branch 4, attended this quarterly inspection exit meeting. The inspectors verified that no proprietary information was retained by the inspectors or documented in this report.

NRC requirements which meet the criteria of the NRC Enforcement
Policy for being dispositioned as
SVs shall be operable in reactor operating modes 1, 2, and 3. TS 3.4.3.1 surveillance
Enclosure requirement states that the
- SV s opening lift setpoints are maintained within + 1% tolerance of the design opening pressure. Contrary to the above, information received by site engineering from a laboratory performing
SV as-found testing, determined that on September 25, 2012, the valve setpoint deficiencies existed with
six
SV were determined to have their as-found setpoints outside of the
SV being outside of their
allowable as-found setpoints was due to setpoint drift. The
SV were replaced
with refurbished
- SV for the 20th Unit 2 operating cycle. The amount of setpoint drift was within the as found Target Rock
SRVs/SV were replaced with refurbished valves that were tested and opened within the allowable + 1% tolerance. The inspectors determined that the finding was of very low safety significance (Green) in accordance with Section A of
Exhibit 2 in Appendix A of IMC 0609, "The Significance Determination Process for
Findings at Power," because the SRV's safety function was not affected. Although
outside the lift setpoint tolerance, the as found
- SV lift pressure values would not have challenged the reactor vessel design maximum pressure rating during the most limiting postulated accident event. The inspectors reviewed
- TS setpoint change submittal to a + 3% tolerance appropriate. Because this finding is of very low safety significance, the as-found out of tolerance
SRVs were replaced with SRVs that had
the proper lift setpoint prior to the Unit 2 reactor plant startup, and the issue was

1, 2012.
RFO during performance of the ST. Both instruments were replaced and calibrated to within acceptable limits
prior to reactor startup. The inspectors determined that the finding was of very low safety significance (Green) in accordance with Section C of Exhibit 2 in Appendix A of IMC 0609, " The Significance Determination Process for Findings at Power,"
because RPS system trip capability was maintained with the 'C' and 'D' instrument
channels. Because this finding is of very low safety significance and has been

CFR 50.47(b). 10 CFR 50.47(b) requires, in part, that a standard emergency classification and action level scheme, the bases of
which includes facility system and effluent parameters, is in use by Exelon. Contrary to the above, between December 2008 and November 2012, the standard emergency classification and action level scheme associated with radiological
effluents at
- PBA [[]]
PS was not updated to reflect the changes in X/Q dispersion factor
that occurred during the December
- 2008 OD [[]]
CM revision. Consequently, the effluent
monitor emergency classification and action level thresholds for the reactor building
exhaust vent stack were non-conservative until this condition was identified and promptly corrected by
- PBAPS in November 2012. The inspectors determined that the finding was of very low safety significance (Green) in accordance with
NRC IMC
0609, Appendix B, "Emergency Preparedness Significance Determination Process,"
Table 5.4-1, because the emergency action level (EAL) classification process would
not be capable of classifying an Unusual Event (UE) within 15 minutes, but would still be capable of declaring all other
