SUBJECT: PERRY NUCLEAR POWER PLANTNRC INTEGRATED INSPECTION REPORT
Dear Mr. Hamilton:
On March 31, 2017, the U.S. Nuclear Regulatory Commission (NRC) completed a baseline
inspection at your Perry Nuclear Power Plant. On April 13, 2016, the NRC inspectors discussed
the results of this inspection with Mr. F. Payne and other members of your staff. The enclosed
report represents the results of this inspection.
Based on the results of this inspection, the NRC has identified one issue that was evaluated
under the risk significance determination process as having very low safety significance
(Green). The NRC has also determined that a violation is associated with this issue. Because
the licensee initiated condition reports to address this issue, this violation is being treated as a
Non-Cited Violation (NCV), consistent with Section 2.3.2 of the Enforcement Policy. The NCV is
described in the subject inspection report. Furthermore, the inspectors documented a licensee-
identified violation which was determined to be of very low safety significance in this report. The
NRC is treating this violation as an NCV consistent with Section 2.3.2.a of the Enforcement
Policy.
If you contest the violations or significance of these NCVs, you should provide a response within
30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear
Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with

SUMMARY
Inspection Report (IR) 05000440/2017001, 01/01/2017 - 03/31/2017, Perry Nuclear Power
Plant; Routine Integrated Inspection Report.
This report covers a 3-month period of inspection by resident inspectors and announced
baseline inspections by regional inspectors. The significance of inspection findings is indicated
by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using
Inspection Manual Chapter (IMC) 0609, "Significance Determination Process," dated
April 29, 2015. All violations of NRC requirements are dispositioned in accordance with the
NRCs Enforcement Policy dated November 1, 2016. The NRC's program for overseeing the
safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor
Oversight Process," Revision 6.
Cornerstone: Mitigating Systems
Green. A finding of very-low safety significance and associated NCV of TS 5.4,
Procedures, was identified by the inspectors for the failure to implement procedures for
combating a loss of shutdown cooling (SDC). Specifically, the licensee failed to
implement its procedure for combating a loss of SDC resulting from emergency service
water (ESW) inoperability and during high decay heat load. This finding was entered
into the licensees Corrective Action Program to perform analyses for various conditions
to identify available alternate methods of decay heat removal and provide associated
procedural guidance.
The performance deficiency was determined to be more-than-minor because it was
associated with the Mitigating Systems cornerstone attribute of design control and
affected the cornerstone objective of ensuring the availability, reliability, and capability of
mitigating systems to respond to initiating events to prevent undesirable consequences.
The finding screened as very-low safety significance (Green) because it was a design
deficiency that did not impact the operability or Probabilistic Risk Assessment
functionality of any mitigating structures, systems, and components. The inspectors did
not identify a cross-cutting aspect associated with this finding because it did not reflect
current performance due to the age of the performance deficiency.
(Section 4OA5.1.b(1))
Licensee-Identified Violations
A Violation of very low safety significance was identified by the licensee and has been
reviewed by the NRC. Corrective actions taken or planned by the licensee have been
entered into the licensees corrective action program (CAP). This violation and CAP
tracking number is listed in Section 4OA7 of this report.

REPORT DETAILS
Summary of Plant Status
The plant began the inspection period at 98 percent power, due to end-of-core life prior to
refueling outage (RFO) 1R16. The operators performed minor power reductions during this
inspection period to support routine surveillances while the plant continued to coastdown until
March 5, when at 12:01 a.m., the plant disconnected from the grid and was shut down for RFO
1R16. The plant remained in RFO 1R16 through the end of the quarter.
1. REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, and
1R04 Equipment Alignment (71111.04)
.1 Quarterly Partial System Walkdowns
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant
systems:
- standby liquid control system (SLC) B;
- division 1 emergency diesel generator (EDG);
- control room emergency ventilation system B; and
- Unit 2 startup transformer.
The inspectors selected these systems based on their risk significance relative to the
Reactor Safety Cornerstones at the time they were inspected. The inspectors attempted
to identify any discrepancies that could impact the function of the system and, therefore,
potentially increase risk. The inspectors reviewed applicable operating procedures,
system diagrams, Updated Safety Analysis Report (USAR), Technical Specification (TS)
requirements, outstanding work orders (WOs), condition reports, and the impact of
ongoing work activities on redundant trains of equipment in order to identify conditions
that could have rendered the systems incapable of performing their intended functions.
The inspectors also walked down accessible portions of the systems to verify system
components and support equipment were aligned correctly and operable.
The inspectors examined the material condition of the components and observed
operating parameters of equipment to verify that there were no obvious deficiencies.
The inspectors also verified that the licensee had properly identified and resolved
equipment alignment problems that could cause initiating events or impact the capability
of mitigating systems or barriers and entered them into the CAP with the appropriate
significance characterization. Documents reviewed are listed in the Attachment to this
report.
These activities constituted four partial system walkdown samples as defined in
inspection procedure (IP) 71111.04-05.

b. Findings
No findings were identified.
.2 Semi-Annual Complete System Walkdown
a. Inspection Scope
On March 6, 2017, the inspectors completed a system alignment inspection of the high
pressure core spray system to verify the functional capability of the system. This system
was selected because it was considered both safety significant and risk significant in the
licensees probabilistic risk assessment. The inspectors walked down the system to
review mechanical and electrical equipment lineups; electrical power availability; system
pressure and temperature indications, as appropriate; component labeling; component
lubrication; component and equipment cooling; hangers and supports; operability of
support systems; and to ensure that ancillary equipment or debris did not interfere with
equipment operation. A review of a sample of past and outstanding WOs was
performed to determine whether any deficiencies significantly affected the system
function. In addition, the inspectors reviewed the CAP database to ensure that system
equipment alignment problems were being identified and appropriately resolved.
Documents reviewed are listed in the Attachment to this report.
These activities constituted one complete system walkdown sample as defined in
IP 71111.04-05.
b. Findings
No findings were identified.
1R05 Fire Protection (71111.05)
.1 Routine Resident Inspector Tours (71111.05Q)
a. Inspection Scope
The inspectors conducted fire protection walkdowns which were focused on availability,
accessibility, and the condition of firefighting equipment in the following risk-significant
plant areas:
- fire zone OCC-1A; control complex 57410;
- fire zone 1RB-1C; containment building, 599, 620, 642, 652, 6647, 599, and
689 elevations;
- fire zone OFH-3; fuel handling building; 6206; and
- fire zone 1RB-1C-1B; drywell; 5836, 599, 6206, and 6368.
The inspectors reviewed areas to assess whether the licensee had implemented a fire
protection program that adequately controlled combustibles and ignition sources within
the plant, effectively maintained fire detection and suppression capability, maintained
passive fire protection features in good material condition, and implemented adequate
compensatory measures for out-of-service, degraded or inoperable fire protection
equipment, systems, or features in accordance with the licensees fire plan.
4
The inspectors selected fire areas based on their overall contribution to internal fire risk
as documented in the plants Individual Plant Examination of External Events with later
additional insights, their potential to impact equipment which could initiate or mitigate a
plant transient, or their impact on the plants ability to respond to a security event.
Using the documents listed in the Attachment to this report, the inspectors verified that
fire hoses and extinguishers were in their designated locations and available for
immediate use; that fire detectors and sprinklers were unobstructed; that transient
material loading was within the analyzed limits; and fire doors, dampers, and penetration
seals appeared to be in satisfactory condition. The inspectors also verified that minor
issues identified during the inspection were entered into the licensees CAP.
Documents reviewed are listed in the Attachment to this report.
These activities constituted five quarterly fire protection inspection samples as defined in
IP 71111.05-05.
b. Findings
No findings were identified.
.2 Annual Fire Protection Drill Observation (71111.05A)
a. Inspection Scope
On February 2, 2017 and February 6, 2017, the inspectors observed two fire brigade
activation unannounced drills. On February 27, 2017, the inspectors observed the
licensee response to a fire on Screen Wash Pump A in the Service Water Building.
Based on these observations, the inspectors evaluated the readiness of the plant fire
brigade to fight fires. The inspectors verified that the licensee staff identified
deficiencies, openly discussed them in a self-critical manner at the drill debrief, and took
appropriate corrective actions. Specific attributes evaluated were:
- proper wearing of turnout gear and self-contained breathing apparatus;
- proper use and layout of fire hoses;
- employment of appropriate firefighting techniques;
- sufficient firefighting equipment brought to the scene;
- effectiveness of fire brigade leader communications, command, and control;
- search for victims and propagation of the fire into other plant areas;
- smoke removal operations;
- utilization of pre-planned strategies;
- adherence to the pre-planned drill scenario; and
- drill objectives.
Documents reviewed are listed in the Attachment to this report.
These activities constituted one annual fire protection inspection sample as defined in
IP 71111.05-05.
b. Findings
No findings were identified.

1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13)
.1 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed the licensee's evaluation and management of plant risk for the
maintenance and emergent work activities affecting risk-significant and safety-related
equipment listed below to verify that the appropriate risk assessments were performed
prior to removing equipment for work:
- high pressure core spray (HPCS) condensate storage tank test pressure
instrument root valve weld repair;
- Unit 2 startup transformer out of service during high winds;
- shutdown risk yellow with Division 1 EDG inoperable;
- shutdown risk yellow during replacement of B ESW pump; and
- Unit 1 startup transformer out of service with switchyard breakers S610 and S620
out of service.
These activities were selected based on their potential risk significance relative to the
Reactor Safety Cornerstones. As applicable for each activity, the inspectors verified that
risk assessments were performed as required by 10 CFR 50.65(a)(4) and were accurate
and complete. When emergent work was performed, the inspectors verified that the
plant risk was promptly reassessed and managed. The inspectors reviewed the scope
of maintenance work, discussed the results of the assessment with the licensee's
probabilistic risk analyst or shift technical advisor, and verified plant conditions were
consistent with the risk assessment. The inspectors also reviewed TS requirements and
walked down portions of redundant safety systems, when applicable, to verify risk
analysis assumptions were valid and applicable requirements were met.
Documents reviewed during this inspection are listed in the Attachment to this report.
These maintenance risk assessments and emergent work control activities constituted
five samples as defined in IP 71111.13-05.
b. Findings
No findings were identified.
1R15 Operability Determinations and Functional Assessments (71111.15)
.1 Operability Evaluations
a. Inspection Scope
The inspectors reviewed the following issues:
- standby liquid control (SLC) B squib valve operability;
- reactor core isolation cooling (RCIC) operability with room watertight door found
open and unattended;
- underdrain and gravity discharge system rock salt intrusion functionality
assessment;
10
- operations with potential of draining the reactor vessel (OPDRV) requirements for
control room emergency recirculation and control room heating, ventilation, and
air conditioning inoperabilities; and
- residual heat removal (RHR) A and B operability due to a degraded snubber.
The inspectors selected these potential operability issues based on the risk significance
of the associated components and systems. The inspectors evaluated the technical
adequacy of the evaluations to ensure that TS operability was properly justified and the
subject component or system remained available such that no unrecognized increase in
risk occurred. The inspectors compared the operability and design criteria in the
appropriate sections of the TS and Updated Safety Analysis Report (USAR) to the
licensees evaluations to determine whether the components or systems were operable.
Where compensatory measures were required to maintain operability, the inspectors
determined whether the measures in place would function as intended and were
properly controlled. The inspectors determined, where appropriate, compliance with
bounding limitations associated with the evaluations. Additionally, the inspectors
reviewed a sampling of corrective action documents to verify that the licensee was
identifying and correcting any deficiencies associated with operability evaluations.
Documents reviewed are listed in the Attachment to this report.
This operability inspection constituted five sample as defined in IP 71111.15-05.
b. Findings
No findings were identified.
1R18 Plant Modifications (71111.18)
.1 Plant Modifications
a. Inspection Scope
The inspectors reviewed the following modification(s):
- ECP 16-0178-000; Diesel Generator Ventilation Bypass Switch Modification.
The inspectors reviewed the configuration changes and associated 10 CFR 50.59 safety
evaluation screening against the design basis, the USAR, and the TS, as applicable, to
verify that the modification did not affect the operability or availability of the affected
system(s). The inspectors, as applicable, observed ongoing and completed work
activities to ensure that the modifications were installed as directed and consistent with
the design control documents; the modifications operated as expected; post-modification
testing adequately demonstrated continued system operability, availability, and reliability;
and that operation of the modifications did not impact the operability of any interfacing
systems. As applicable, the inspectors verified that relevant procedure, design, and
licensing documents were properly updated. Lastly, the inspectors discussed the plant
modification with operations, engineering, and training personnel to ensure that the
individuals were aware of how the operation with the plant modification in place could
impact overall plant performance. Documents reviewed are listed in the Attachment to
this report.
11
This inspection constituted one permanent plant modification sample as defined in
IP 71111.18-05.
b. Findings
No findings were identified.
1R19 Post-Maintenance Testing (71111.19)
.1 Post-Maintenance Testing
a. Inspection Scope
The inspectors reviewed the following post-maintenance (PM) activities to verify that
procedures and test activities were adequate to ensure system operability and functional
capability:
- Unit 2 start-up transformer replacement PM test.
These activities were selected based upon the structure, system, or component's ability
to impact risk. The inspectors evaluated these activities for the following (as applicable):
the effect of testing on the plant had been adequately addressed; testing was adequate
for the maintenance performed; acceptance criteria were clear and demonstrated
operational readiness; test instrumentation was appropriate; tests were performed as
written in accordance with properly reviewed and approved procedures; equipment was
returned to its operational status following testing (temporary modifications or jumpers
required for test performance were properly removed after test completion); and test
documentation was properly evaluated. The inspectors evaluated the activities against
TSs, the UFSAR, Title 10 of the Code of Federal Regulations (10 CFR) Part 50
requirements, licensee procedures, and various NRC generic communications to ensure
that the test results adequately ensured that the equipment met the licensing basis and
design requirements. In addition, the inspectors reviewed corrective action documents
associated with post-maintenance tests to determine whether the licensee was
identifying problems and entering them in the CAP and that the problems were being
corrected commensurate with their importance to safety. Documents reviewed are listed
in the Attachment to this report.
This inspection constituted six post-maintenance testing sample as defined in
IP 71111.19-05.
b. Findings
No findings were identified.

1R20 Outage Activities (71111.20)
.1 Refueling Outage Activities
a. Inspection Scope
The inspectors reviewed the Outage Safety Plan (OSP) and contingency plans for the
RFO 1R16 to confirm that the licensee had appropriately considered risk, industry
experience, and previous site-specific problems in developing and implementing a plan
that assured maintenance of defense-in-depth. During the RFO, the inspectors
observed portions of the shutdown and cooldown processes and monitored licensee
controls over the outage activities listed below:
- licensee configuration management, including maintenance of defense-in-depth
commensurate with the OSP for key safety functions and compliance with the
applicable TS when taking equipment out of service;
- implementation of clearance activities and confirmation that tags were properly
hung and equipment appropriately configured to safely support the work or
testing;
- installation and configuration of reactor coolant pressure, level, and temperature
instruments to provide accurate indication, accounting for instrument error;
- controls over the status and configuration of electrical systems to ensure that
TS and OSP requirements were met, and controls over switchyard activities;
- monitoring of decay heat removal processes, systems, and components;
- controls to ensure that outage work was not impacting the ability of the operators
to operate the spent fuel pool cooling system;
- reactor water inventory controls including flow paths, configurations, and
alternative means for inventory addition, and controls to prevent inventory loss;
- controls over activities that could affect reactivity;
- maintenance of secondary containment as required by TS;
- licensee fatigue management, as required by 10 CFR 26, Subpart I;
- refueling activities, including fuel handling and sipping to detect fuel assembly
leakage;
- startup and ascension to full power operation, tracking of startup prerequisites,
walkdown of the drywell (primary containment) to verify that debris had not been

2RS2 Occupational As-Low-As-Reasonably-Achievable Planning and Controls (71124.02)
.1 Radiological Work Planning (02.02)
a. Inspection Scope
The inspectors selected three to five work activities of the highest exposure significance
or involve work in high dose rate areas.
The inspectors reviewed the radiological work planning as-low-as-reasonably-achievable
(ALARA) evaluations, initial and revised exposure estimates, and exposure mitigation
requirements. The inspectors determined whether the licensee had reasonably grouped
the radiological work into work activities.
The inspectors assessed whether the licensees planning identified appropriate dose
reduction techniques; appropriately considered alternate reduction features; and defined
reasonable dose goals. The inspectors evaluated whether the licensees ALARA
assessment had taken into account decreased worker efficiency from use of respiratory
protective devices and/or heat stress mitigation equipment. The inspectors determined
whether the licensees work planning considered the use of remote technologies and
dose reduction insights from industry and plant-specific operating experience. The
inspectors assessed whether these ALARA requirements were integrated into work

.2 Implementation of As-Low-As-Reasonably-Achievable and Radiological Work Controls
(02.04)
a. Inspection Scope
The inspectors reviewed the radiological administrative, operational, and engineering
controls planned for selected radiologically significant work activities and evaluated the
integration of these controls and ALARA requirements into work packages, work
procedures and/or RWPs.
The inspectors observed in-plant work activities and assessed whether the licensee had
effectively integrated the planned administrative, operational, and engineering controls
into the actual field work to maintain occupational exposure ALARA. The inspectors
observed pre-job briefings, and determined whether the planned controls were
discussed with workers. The inspectors evaluated the placement and use of shielding,
contamination controls, airborne controls, RWP controls, and other engineering work
controls against the ALARA plans.
The inspectors assessed licensee activities associated with work-in-progress to ensure
the licensee was tracking doses, performed timely in-progress reviews, and when jobs
did not trend as expected, appropriately communicated additional methods to be used to
reduce dose. The inspectors evaluated whether health physics and ALARA staff were
involved with the management of radiological work control when in-field activities
deviated from the planned controls. The inspectors assessed whether the Outage
Control Center and station management provided sufficient support for ALARA
re-planning.
The inspectors assessed the involvement of ALARA staff with emergent work activities

4OA2 Identification and Resolution of Problems (71152)
.1 Routine Review of Items Entered into the Corrective Action Program
a. Inspection Scope
As discussed in previous sections of this report, the inspectors routinely reviewed issues
during baseline inspection activities and plant status reviews to verify they were being
entered into the licensees CAP at an appropriate threshold, adequate attention was
being given to timely corrective actions, and adverse trends were identified and
addressed. Some minor issues were entered into the licensees CAP as a result of the
inspectors observations; however, they are not discussed in this report.
These routine reviews for the identification and resolution of problems did not constitute
any additional inspection samples. Instead, by procedure they were considered an
integral part of the inspections performed during the quarter.
23
b. Findings
No findings were identified.
.2 Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a review of the licensees CAP and associated documents
to identify trends that could indicate the existence of a more significant safety issue.
The inspectors review was focused on repetitive equipment issues, but also considered
the results of daily inspector CAP item screening discussed in Section 4OA2.1 above,
licensee trending efforts, and licensee human performance results. The inspectors
review nominally considered the 6-month period of July 1, 2016 through
December 31, 2016, although some examples expanded beyond those dates where the
scope of the trend warranted.
The review also included issues documented outside the CAP in major equipment
problem lists, repetitive and/or rework maintenance lists, departmental
problem/challenges lists, system health reports, quality assurance audit/surveillance
reports, self-assessment reports, and Maintenance Rule assessments. The inspectors
compared and contrasted their results with the results contained in the licensees
CAP trending reports. Corrective actions associated with a sample of the issues
identified in the licensees trending reports were reviewed for adequacy.
This review constituted one semi-annual trend review inspection sample as defined in
b. Findings
No findings were identified.
.3 Annual Follow-up of Selected Issues: Reviewed Licensee Corrective Actions for Failure
to Keep and Maintain Records that Include the Location and the Unique Identity of
Special Nuclear Material Items and Failure to Follow Written Material Control and
Accounting Procedures
a. Inspection Scope
During a review of items entered in the licensees CAP, the inspectors recognized
five CRs that focused on the licensees handling of Special Nuclear Material (SNM).
The first four CRs were written to document findings identified by the NRC during the
biennial Material Control & Accounting (MC&A) inspection, conducted in October and
November 2016. The fifth CR documented the movement of SNM from the nuclear
instrument cabinet in the fuel handling building to the instrument & calibration (I&C) hot
shop in the intermediate building without required documentation and independent
verification.
The inspectors reviewed the corrective actions in each of the CRs listed above. The
licensee has completed all corrective actions for CRs generated from the MC&A
inspection last year, with the exception of one. The corrective actions for the
undocumented transfer of SNM from its assigned storage location to the I&C hot shop
24
on intermediate building 654 elevation included documenting the return of the SNM to
the NI storage cabinet in the fuel handling building, a stand down on NI control and
accountability with the reactor engineering group, and human performance event
response. During their reviews of these five CRs, the inspectors made the following
observations.
- The four CRs written to address the NCV issued in Perry Nuclear Power
Plant - NRC Material Control and Accounting Program IR 05000440/2016406
were processed as Category-AF (adverse fix). Procedure NOP-LP-2001,
Corrective Action Program, Revision 38, states, in part, in Attachment 2,
Condition Report Evaluation Methods, that Fix - Evaluation Code F is not
sufficient for process, program, or equipment issues that result in: NRC
cited/non-cited violations. The inspectors documented this same observation in
Perry Nuclear Power PlantNRC Integrated IR 05000440/2016001 for CR
2015-11597, Potential NRC Violation concerning operation of the DG ventilation
fans, dated September 2, 2015, which was also documented as an NCV in Perry
Nuclear Power PlantNRC Integrated IR 05000440/2015003.
- NOP-LP-2001; Corrective Action Program, Revision 38, a quality procedure,
states, in part, that CRs shall be written to document receipt of NRC Findings or
Cited or Non-Cited Violations in accordance with NOBP-LP-4014 to specifically
address the issue(s) as stated in the wording received from the NRC, and include
actions to correct the finding or violation. Nuclear Operating Business Practice
NOBP-LP-4014; Managing Regulatory Interface; Revision 6, states, in part, in
Section 2.1.2, Adherence to this business practice is mandatory for NRC
inspections. NOBP-LP-4014, also states, in part, in Section 4.1.6.5, Ensure
separate CRs have been written for each potential and confirmed NRC inspector
finding or violation, recommending at least a causal evaluation both because of
the regulatory significance (violation of regulatory requirements) and to ensure
organizational factors contributing to cross-cutting aspects are considered. The
four CRs written for the MC&A NCV were categorized as adverse fix and did not
document or address the cross-cutting aspect, Change Management (H.3) in the
area of Human Performance. Additionally, no other CR was written to address
the cross-cutting aspect after the NCV was issued in Perry Nuclear Power
PlantNRC Material Control and Accounting Program IR 05000440/2016406.
The inspectors concluded that these were minor findings as there were only two
examples of the licensees failure to follow a quality procedure and there is no regulatory
requirement to write a condition report to address individual cross-cutting aspects
assigned to a NCV.
This review constituted one in-depth problem identification and resolution sample as
defined in IP 71152-05.
b. Findings
No findings were identified.

.4 Annual Follow-up of Selected Issues: Review of Licensees Corrective Actions for
Failing to Perform an Engineering Evaluation for the Continued Functionality of the
Underdrain and Gravity Discharge Systems as a Result of Rock Salt Intrusion and its
Potential Long Term Corrosive Effects on the Systems Porous Concrete
a. Inspection Scope
In October 2016, the inspectors identified a severity level IV NCV of 10 CFR 50.59(d)(1),
Changes, Test, and Experiments, and associated finding for the licensees failure to
perform a written evaluation that provided the basis for the determination that a change
did not require a license amendment. Specifically, the licensee made a change pursuant
to 10 CFR 50.59(c) with the installation of grated manhole covers, replacing the rubber
gasket, watertight manhole covers for the underdrain and gravity discharge systems and
did not provide a basis for the determination that this change would not result in a more
than a minimal increase in the likelihood of occurrence of a malfunction of a system
structure or component important to safety. The licensee entered this issue into the
CAP as CR 2016-11864 and performed a prompt operability determination to show that
the underdrain and gravity drain systems remained functional while the engineering
change package was developed to support the change and bring the underdrain and
gravity discharge systems into compliance with the design basis. In January 2017 the
inspectors questioned the continued functionality of the underdrain and gravity discharge
systems based on the introduction of rock salt into the systems from the treatment of
roadways and travel paths during the winter months and its degrading effects on the
porous concrete in the systems. The licensee recognized that the prompt functionality
assessment did not address the effects of sodium chloride on the underdrain and gravity
discharge systems, nor its effects on the emergency service water system. The licensee
determined that continued functionality, in the short term, was reasonably assured as
degradation of the porous concrete was more of a long term concern and as such
continued functionality remained during the investigation and evaluation of the longer
term degradation of the porous concrete by the intrusion of rock salt into the systems.
The licensee evaluated the inspectors concerns and concluded that the introduction of
rock salt into the systems did not have any adverse impacts that would comprise the
expectation of continued functionality of the underdrain and gravity discharge systems,
the emergency service water system, or the plant buildings containing safety related
systems.
During their review of CR 2016-11864, the inspectors made the following observations.
- The licensees functionality assessment involving the removal of the solid
watertight gasketed covers, described in the licensees USAR and replacing
those covers with gratings in September 2016, did not take into account the
introduction of rock salt into the underdrain and gravity discharge systems, and
the intrusion of additional saline water into the emergency service water system.
- NOP-LP-2001; Corrective Action Program; Revision 38, in Attachment 1,
Adverse Condition or Non-Adverse Conditions, lists Condition that may result
in a NRC violation, or has significance within a regulatory context as an adverse
condition. The licensee failed to document the inspectors concerns, for a
potential condition adverse to quality in its CAP program from January 6, 2017
until March 13, 2017.
26
The inspectors concluded that these were minor findings as the first observation was a
violation that was determined to be minor because the failure to evaluate the intrusion of
rock salt did not impact the systems functionality and the second finding was only one
example of the licensees failure to follow a quality procedure.
This review constituted one in-depth problem identification and resolution sample as
defined in IP 71152-05.
b. Findings
No findings were identified.
4OA5 Other Activities
.1 (Closed) NRC Temporary Instruction 2515/192, Inspection of the Licensees Interim
Compensatory Measures Associated with the Open Phase Condition Design
Vulnerabilities in Electric Power Systems
a. Inspection Scope
The objective of this performance based temporary instruction (TI) is to verify
implementation of interim compensatory measures associated with an open phase
condition (OPC) design vulnerability in electric power system for operating reactors. The
inspectors conducted an inspection to determine if the licensee had implemented the
following interim compensatory measures. These compensatory measures are to
remain in place until permanent automatic detection and protection schemes are
installed and declared operable for OPC design vulnerability. The inspectors verified the
following:
- The licensee had identified and discussed with plant staff the lessons-learned
from the OPC events at the US operating plants including the Byron station OPC
event and its consequences. This includes conducting operator training for
promptly diagnosing, recognizing consequences, and responding to an OPC
event.
- The licensee had updated plant operating procedures to help operators promptly
diagnose and respond to OPC events on off-site power sources credited for safe
shutdown of the plant.
- The licensee had established and continue to implement periodic walkdown
activities to inspect switchyard equipment such as insulators, disconnect
switches, and transmission line and transformer connections associated with the
offsite power circuits to detect a visible OPC.
The licensee had ensured that routine maintenance and testing activities on switchyard
components have been implemented and maintained. As part of the maintenance and
testing activities, the licensee assessed and managed plant risk in accordance with 10
CFR 50.65(a) (4) requirements.
b. Findings and Observations
No findings of significance were identified.
27
.2 (Closed) Violation 05000440/2015010-01; Unqualified Radiation Protection Manager
On December 4, 2015, Notice of Violation 05000440/2015010-01 was issued for the
failure to take corrective action to comply with TS 5.3.1 and Regulatory Guide (RG) 1.8,
dated September 1975 regarding the qualifications of the individual performing duties of
the Radiation Protection Manager (RPM). On January 12, 2016, the licensee appointed
an individual as RPM with qualifications necessary to satisfy the requirements specified
in TS 5.3.1 and RG 1.8, dated September, 1975. The inspectors concluded the
licensees corrective actions were acceptable. This violation is closed.
.3 (Closed) Unresolved Item 05000440/2013008-03: Lack of Alternate Methods of Decay
Heat Removal
a. Inspection Scope
The NRC documented an unresolved item (URI) in Inspection Report 5000440/2013008
(ML13276A131) involving the unavailability of alternate methods of decay heat removal
that could be credited to combat a loss of SDC resulting from ESW inoperability and
while in MODE 4 with high decay heat load. The issue was left unresolved pending
further review and determination of NRC actions to resolve the issue. During this
inspection period, the inspectors consulted with the Office of Enforcement and Technical
Specification Branch of the Office of Nuclear Reactor Regulations about this issue.
The documents that were reviewed are included in the Attachment to this report. This
review did not represent an inspection sample. This URI is closed.
b. Findings
(1) Failure to Establish Procedures for Combating a Loss of Shutdown Cooling
Introduction: A finding of very-low safety significance and associated NCV of TS 5.4,
Procedures, was identified by the inspectors for the failure to implement procedures for
combating a loss of SDC. Specifically, the licensee did not have a procedure which
could be effectively implemented for combating a loss of SDC resulting from ESW
inoperability and during high decay heat load.
Description: As described in IR 05000440/2013008, the licensee was unable to meet
Technical Specification 3.4.10 regarding establishment of an alternate method for decay
heat removal on May 21, 2004, and on October 19, 2009, when one or both of the ESW
systems were declared inoperable during shutdown conditions. Specifically, TS Limiting
Condition of Operation (LCO) 3.4.10, Residual Heat Removal Shutdown Cooling
System - Cold Shutdown, requires, in part, two shutdown cooling subsystems operable
in MODE 4 when heat losses to the ambient were not sufficient to maintain average
reactor coolant temperature below 200 degrees Fahrenheit. With one or two shutdown
cooling subsystems inoperable, TS 3.4.10, Required Action A.1, required the licensee to
verify an alternate method of decay heat removal was available for each inoperable
shutdown cooling subsystem within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> thereafter. The
associated TS Basis described the alternate method as one that re-establishes backup
decay heat removal capabilities similar to the requirements of the LCO. In addition, it
stated, The required cooling capacity of the alternate method should be ensured by
verifying (by calculation or demonstration) its capability to maintain or reduce
temperature. As a result of these events, the licensee installed the Alternate Decay
28
Heat Removal (ADHR) system to aid in TS compliance, in MODE 4, by providing an
additional decay heat removal method that does not rely upon RHR or ESW. Similar
incidents also occurred on June 11, 2007, and on February 11, 2016. The 2004 and
2007 incidents resulted in NCVs, which were documented in IR 05000440/2004011 and
IR 05000440/2007005, respectively.
During the 2013 Evaluations of Changes, Tests and Experiments and Permanent Plant
Modifications Inspection (i.e., Mod/50.59 Inspection), the inspectors reviewed the
associated 10 CFR 50.59 evaluation (i.e., Evaluation 05-04712, Installation of ADHR
System) which stated, The intent of the ADHR system is to assure TS compliance in
MODE 4 by providing an additional alternate decay heat removal option that does not
rely upon RHR or ESW. However, the inspectors noted the following concerns:
- the ADHR system provided only one alternate method and its design was limited
to a heat removal rate which bounded the approximate core decay heat
production rate 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after a plant shutdown from sustained 100 percent
power.
process flow to the heat exchanger was available. This condition was captured
in the CAP as CR 2013-06220. The associated functionality assessment
determined ADHR was limited to a heat removal rate which bounded the
approximate core decay heat production rate 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> after a shutdown from
sustained 100 percent power for refueling outage 1R15.
- the licensee also revised Procedure ONI-E12-2, Loss of Decay Heat Removal,
by adding Attachment 11, Cold Shutdown Decay Heat Removal by Steaming.
This attachment contained instructions to establish one alternate method of
decay heat removal independent of ESW. However, its effectiveness to re-
establish backup decay heat removal capabilities similar to the requirements of
LCO 3.4.10 had not been verified. Specifically, the attachment included a note
stating, It will be necessary to validate the effectiveness of this attachment to
maintain or reduce reactor pressure vessel temperature (by Engineering
calculation or demonstration) if qualifying this as an ADHR method per TS 3.4.9
and 3.4.10. In response to the inspectors questions, the licensee estimated this
method was limited to a heat removal rate which bounded the approximate core
decay heat production rate 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after a shutdown from sustained 100
percent power.
- the ADHR system is maintained in a dry condition and requires more than an
hour to fill and vent in order to be declared operational.
Based on this information, the inspectors concluded that for the October 19, 2009,
occurrence, the plant failed to implement an alternate method of decay heat removal that
could be verified to be available within an hour following the loss of a train of ESW while
in Mode 4. The inspectors also noted that during normal shutdown conditions, the
licensee transitions from 100 percent power to MODE 4 in a few hours. For instance,
the transition to MODE 4 during the 1R13 refueling outage occurred in about five hours.
In the first three loss of SDC instances described above, the licensee submitted
Licensee Event Report (LERs) stating that the site could not demonstrate the
requirements of TS 3.4.10 and was operating in a condition prohibited by TS and
therefore reported the issue under 10 CFR 50.73(a)(2)(i)(B) as identified in
LER 4402004001, LER 4402007002, and LER 4402009003.
29
The licensee captured the inspectors concerns in their CAP as CR 2016-11987. The
corrective actions considered at the time of this inspection were to perform calculations
for various conditions to determine available alternatives for MODE 4 entry at less than
24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or demonstrate alternatives are viable; and provide procedural guidance based
on the results.
Analysis: The inspectors determined the failure to implement procedures for combating
a loss of SDC resulting from all applicable conditions was contrary to TS 5.4,
Procedures, and was a performance deficiency. The inspectors determined the
performance deficiency was more-than-minor because it was associated with the
Mitigating Systems cornerstone attribute of design control and affected the cornerstone
objective of ensuring the availability, reliability, and capability of mitigating systems to
respond to initiating events to prevent undesirable consequences. Specifically, the
licensee cannot verify alternate methods of decay heat removal are available, as
required by Required Action A.1 upon discovery that LCO 3.4.10, is not met.
The inspectors determined the finding could be evaluated using the Significance
Determination Process in accordance with Inspection Manual Chapter 0609,
Significance Determination Process, Attachment 4, Initial Characterization of
Findings, dated October 7, 2016 and Appendix G, Shutdown Operations Significance
Determination Process, Exhibit 3, Mitigating Systems Screening Questions, dated
May 9, 2014. The finding screened as very-low safety significance (Green) because it
did not affect the operability or Probabilistic Risk Assessment functionality of any
mitigating SSCs.
The inspectors did not identify a cross-cutting aspect associated with this finding
because it was not confirmed to reflect current performance due to the age of the
performance deficiency.
Enforcement: Technical Specification 5.4, Procedures, stated, in part, that written
procedures shall be established, implemented, and maintained covering the applicable
procedures recommended in Regulatory Guide 1.33, Quality Assurance Program
Requirements, Revision 2, Appendix A. Regulatory Guide 1.33, Appendix A, Section 6,
addressed Procedures for Combating Emergencies and Other Significant Events, and
sub-section 6.h, addressed Loss of Shutdown Cooling. In addition, TS LCO 3.0.2
requires that upon discovery of a failure to meet an LCO, the Required Actions of the
associated Conditions shall be met. With one or two SDC subsystems inoperable,
Required Action A.1 of TS 3.4.10 requires the licensee to verify an alternate method of
decay heat removal was available for each inoperable SDC subsystem within one hour
and once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> thereafter. Alternate methods of decay heat removal that satisfy
this TS requirement are defined in the associated TS Basis as those that re-establish
backup decay heat removal capabilities similar to the requirements of TS 3.4.10.
Contrary to the above, on October 9, 2009, the licensee failed to implement a procedure
recommended in Appendix A of Regulatory Guide 1.33, Revision 2. Specifically, the
licensee could not implement its procedure for combating a loss of SDC resulting from
ESW inoperability with high decay heat load. As a result, upon discovery of a failure to
meet LCO 3.4.10 during a loss of ESW with high decay heat load, Required Action A.1
could not be met as required by LCO 3.0.2. On October 19, 2009, at 0429 hours0.00497 days <br />0.119 hours <br />7.093254e-4 weeks <br />1.632345e-4 months <br /> the
train B of SDC was declared inoperable, as a result of the loss of train B of ESW, and
the licensee was unable to implement procedure ONI-E12-2 because an alternate
30
method of decay heat removal with a capability similar to the requirements of TS 3.4.10
could not be verified to be available within one hour.
At the time of this inspection period, the licensee was still evaluating its planned
corrective actions. However, the inspectors determined that the continued
non-compliance did not present an immediate safety concern because all shutdown
cooling subsystems were expected to be operable if needed during this inspection
period.
Because this violation was of very-low safety significance and was entered into the
licensees CAP as CR 2016-11931, this violation is being treated as a NCV, consistent
with Section 2.3.2 of the NRC Enforcement Policy (NCV 05000440/2017001-01, Failure
to Implement Procedures for Combating a Loss of Shutdown Cooling).

4OA7 Licensee-Identified Violations
The following violation of very low significance (Green) was identified by the licensee
and is a violation of NRC requirements, which meet the criteria of the NRC Enforcement
Policy for being dispositioned as a Non-Cited Violation (NCV).
In part, 10 CFR 20.1703 (c)(5) states, The licensee shall implement and maintain a
respiratory protection program that includesDetermination by a physician that the
individual user is medically fit to use respiratory protection equipment.
Contrary to the above, the licensee identified that an individual wore a powered air
purifying respirator (PAPR) three times during the period of March 6-7, 2017 for the
purpose of radiological protection without the required medical determination. This was
31
entered into the licensees corrective action program, CR 2017-02957, Vessel
Technician Wore PAPR Three Times without Being Qualified. The significance of this
violation was determined in accordance with IMC 0609 Appendix C, Occupational
Radiation Safety Significance Determination Process dated August 19, 2008. This
violation was determined to be of very low safety significance (Green), because this
violation was not associated with ALARA Planning or Work Controls, there was no
overexposure nor substantial potential for overexposure and the ability to access dose
was not compromised.
