PWR Inservice Inspection Activities Sample - Steam Generator Tube Inspection Activities
(Section 03.04) (1 Sample)
The inspectors verified that the licensee is monitoring the steam generator tube integrity
appropriately through a review of the results of the 100 percent full length eddy current
inspection of all tubes with bobbin coil probe. Four tubes in replacement steam generator 1
exhibited wear that exceeded the tube integrity criteria provided in the degradation
assessment (DA).
1. There were four tubes that required in situ pressure testing to support the condition
monitoring assessment based on the DA and Electric Power Research Institute in situ
pressure test guidelines. Additional discussion of these activities is included in an
unresolved item in the results section of this report.
- Two tubes from steam generator 1 (R1 C112 and R1 C138) were tested over the
range of prescribed test pressures and successfully reached and maintained the
structural limit pressure test of 5500 psi. No tube leakage was measured at any test
pressure for these two tubes.
- Two tubes from steam generator 1 (R1 C4 and R2 C35) were tested over the range
of prescribed test pressures. Tube R1 C4 was unable to reach the structural limit test
pressure as it experienced pop-through at 5243 psi. No leakage was measured in
this tube at lower test pressures prior to the pop-through. Tube location R2 C35 was
able to temporarily achieve the structural limit test pressure point at 5500 psi, but lost
leak tight integrity via pop-through after a combined 131 seconds above the target
pressure of 5500 psi. The combined 131 seconds at pressure was achieved by a
period of 41 seconds above the test target, then briefly dropping below 5500 psi
before being re-established above 5500 psi for 90 seconds prior to the pop through.
No tube leakage was observed at any test pressure below the structural limit test.
2. No tube leakage was reported during this operating interval. The inspectors verified that
the licensee is monitoring the steam generator tube integrity appropriately through
a review of the examinations.
There were a total of 48 tubes plugged, including 27 tubes in steam generator 1 and
21 tubes in steam generator 2.
Problem Identification and Resolution. Review of in-service inspection items. (Inspection
Procedure 71152 - Problem Identification and Resolution). The inspector evaluated a
sample of 16 condition reports associated with in-service inspection activities. No

INSPECTION RESULTS
Unresolved Item Steam Generator 1 In-Situ Tube Pressure Testing Failures. 71111.08P
(Open) URI 05000382/2023004-01
Description: The inspectors identified an unresolved item (URI) associated with the licensees
failure to meet the steam generator tube integrity performance criterion in technical
specification (TS) 6.5.9.b.1, Steam Generator Program. Specifically, Waterford 3s Steam
Generator Program structural integrity performance criterion includes retaining a safety factor
of 3.0 against burst under normal steady state full power operation primary to secondary
pressure differential and a safety factor of 1.4 against burst applied to the design basis
accident primary to secondary pressure differentials. The licensee extended the inspection
interval for the tube inspections from three cycles to four based on NRC approval of
TSTF-577 (Technical Specification Task Force), Revised Frequencies for Steam Generator
Tube Inspections and reevaluation of the refueling outage 21 (2017) operational
assessment. During the Unit 3 refueling outage 25 four tubes failed to meet the condition
monitoring criteria.
Technical specification 6.5.9, Steam Generator Program, requires that a program be
established and implemented to ensure that steam generator tube integrity is maintained.
Pursuant to TS 6.5.9, tube integrity is maintained when the steam generator performance
criteria are met. There are three steam generator performance criteria: structural integrity,
accident induced leakage, and operational leakage. Meeting the steam generator
performance criteria provides reasonable assurance of maintaining tube integrity at normal
and accident condition. TS 6.5.9 also states that the Steam Generator Program shall include
provisions for steam generator tube plugging criteria. Tubes found by in-service inspection to
contain flaws with a depth equal to or exceeding 40 percent on the nominal tube wall

thickness shall be plugged.
In steam generator 1, there were four tubes identified as having flaws that exceeded the
condition monitoring structural limit at the tube support plates. Eddy current testing and sizing
was performed, and the structural equivalent flaw parameters were calculated. The structural
equivalent parameters were compared to the condition monitoring limit curve and determined
that deficiencies existed. Since the tube performance criteria were not met analytically, in-situ
pressure testing of the four tubes was required. Other than the four tubes in-situ pressure
tested, all other tubes satisfied performance criteria analytically. In steam generator 2, the
tube performance criteria were satisfied analytically.
Two of the four tubes in-situ pressure tested in steam generator 1 failed to meet Structural
Integrity Performance Criterion. The examination results were also used, together with outage
repairs (i.e., tube plugging), to demonstrate that the performance criteria would be met for
upcoming cycles 26 through 27.
Upon completion of the tube examinations of pre and post pressure testing, +Point and Array
probe data confirmed that flaws in steam generator 1, tube Row 1 (R1) - Column 4 (C4) and
in tube R2-C35 had failed and burst. The inspectors reviewed condition report
CR-WF3-2023-17005 which provides additional information and a causal evaluation.
The event was reported as an 8-hour, non-emergency notification per 10CFR72(b)(3)(ii)9A)
as a degraded condition for not meeting the performance criteria for steam generator
structural integrity in accordance with TS 6.5.9.b.1, Steam Generator Program, due to two
tube failures in steam generator 1. Event notification (EN) 56834 was reported to NRC
operations center on November 5, 2023.
The licensees apparent cause analysis and EN 56834 identified that the vendor used
non-conservation assumptions in the revised operational assessment to extend the
inspection interval. Additional inspection is required to determine if there is a performance
deficiency associated with this issue.
Planned Closure Actions: The NRC staff will review the available information, including a
pending vendor causal evaluation, to determine if any performance deficiencies exist and
identify any possible regulatory outcomes.
Licensee Actions: The licensee has placed the information into their corrective action
program and will have the document reviews and corrective actions developed in
January 2024.

The inspectors identified a Green finding associated with a non-cited violation (NCV) of
Technical Specification (TS) 6.8.1.a for a failure to follow as low as reasonably achievable
(ALARA) planning and control procedures during the refueling outage 24 (2022). Specifically,
the licensee's planning or radiological controls did not prevent unplanned dose for two
separate work activities conducted during the refueling outage.
Description: During refueling outage 24 (2022), the licensee performed work activities under
RWP 2022-0512, "1RE24 Steam Generator 1 and 2 Feedring Mod," and RWP 2022-0615,
"1RE24 Remove/Replace Pressurizer Heater." The accrued dose for each of these activities
exceeded the planned dose estimate by 64 percent due to issues that NRC deemed were
preventable or reasonably foreseeable. This presented two examples for a failure to follow
ALARA planning and control procedures. These issues involved changing radiological
conditions, delays in staging materials needed for work, inaccurate person-hours from various
teams, and uncoordinated resources.
The first example is relative to RWP 2022-0512, "1RE24 Steam Generator 1 and 2 Feedring
Mod," revision 2, which addressed the radiological work with the steam generators and the
feedring. While conducting this work, multiple issues occurred. The steam generator design
for installation was a new design to the site. The new design had higher u-tubes relative to
the feedwater injection area than the previous steam generators installed. The licensee
determined that the new design required more shielding for the foreign object search and
retrieval activities, so they added more magnetic tungsten shielding. However, this additional
shielding was not as effective as planned relative to the body positioning of the workers in
that the licensee did not account for the larger plane source of the steam generators. The
workers were exposed to higher than planned levels of radiation resulting in the additional
dose. The actual dose for this task significantly increased the planned dose due to various
issues identified during the review of the work activity.
Some of these issues were:
- There was difficulty with the torquing of bolts, in which multiple bolts were
over-torqued and had to be addressed. The NRC deemed this as a human
performance error and therefore preventable. NRC gave no credit for this additional
dose.
- There were delays in staging material due to improper planning for the needed
resources. For instance, the polar crane hook was unavailable when needed to stage
materials. NRC deemed this as a human performance error and preventable. NRC
gave no credit for this additional dose.
- Teams involved with the work activity underestimated activities and resources
needed. For instance, the project team underestimated resources needed to assist
the containment coordinator. NRC deemed this as a human performance error and
preventable. NRC gave no credit for this additional dose.
- The licensee used surveys from mockup activities during the pre-outage phase and
subsequently, the radiological levels increased. However, the licensee failed to
confirm the new radiological conditions and properly address the changing
radiological conditions in their planning phase prior to work. NRC deemed this as a
human performance error and preventable. NRC gave no credit for this additional
dose.
- During the job, the licensee experienced retrieval of foreign material on the secondary
side of the steam generators. NRC determined this was an emergent issue that was
not preventable or foreseeable. NRC gave additional dose credit in the amount of
208 millirem.
14
Based on the above information reviewed, the NRC determined that an additional
208 millirem may be added to the licensee's initial dose estimate of 3.656 rem, resulting in a
new NRC revised dose estimate of 3.864 rem. When comparing this to the actual accrued
dose of the RWP (6.352 rem), NRC determined that the actual collective dose exceeded the
revised dose estimate by approximately 64 percent.
The second example is relative to RWP 2022-0615, "1RE24 Remove/Replace Pressurizer
Heater," revision 6, which addressed the radiological work to remove and replace the
pressurizer heaters. While conducting this work, the licensee had trouble in various aspects
of the activity. The three primary issues involved: (1) higher dose rates on the instrument
lines requiring more shielding, (2) removing the packaging of the new heater equipment, and
(3) more time needed to remove the heaters due to issues with the type of respiratory
equipment used.
The details of these three issues included:
- The licensee surveyed the instrument lines prior to work and identified additional
shielding was needed to protect workers from unintended dose. NRC gave additional
dose credit in the amount of 132 millirem for adding shielding for this activity.
- The licensee had difficulty removing the type of packaging used on the new heater
equipment, which seemed to have crystallized, and there was also wire meshing that
proved difficult to remove. NRC gave additional dose credit in the amount of 372
millirem.
- The licensee chose to use a Pureflo respirator hood, described as a loose-fitting,
all-in-one powered air purifying respirator (PAPR). Workers experienced fogging of
these PAPRs that slowed down work significantly. However, NRC determined that the
time estimate used for removal of each heater was inadequate and underestimated.
The licensee estimated the removal of ten heaters at approximately 36 minutes per
heater but needed about 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> per heater. Partial credit for additional dose was
given due to unforeseen conditions of the PAPRs fogging resulting in slower work
performance, but not for the general underestimation of man-hours needed for each
heater removal. As a result, NRC gave additional dose credit in the amount of 724
millirem. NRC added this additional dose to the initial dose estimate, which generally
allowed about one additional man-hour for the removal of each heater.
Based on the above information reviewed, the NRC determined that a total of 1.228 rem
(132 millirem + 372 millirem + 724 millirem) in additional dose may be credited to the
licensee's initial dose estimate of 3.262 rem, resulting in a new NRC revised dose estimate of
4.490 rem. When comparing this to the actual accrued dose of the RWP (7.383 rem), NRC
determined that the actual collective dose exceeded the revised dose estimate by
approximately 64 percent.
As the inspectors reviewed the ALARA procedure, EN-RP-110, Step 4.0[8], the following
steps were not consistently followed in RWPs 2022-0512 and 2022-0615:
[8] Planning and Scheduling / Outage Groups: Responsibilities include the following:
- Providing accurate worksite person-hours and accurate work locations for ALARA
Planning purposes.
15
o In NRC's review, the worksite person hours for removal and replacement of
the pressurizer heaters and the steam generator activities were not accurate
for planning purposes to maintain doses ALARA
- Providing detailed work plans to allow for ALARA Planning to designate adequate
radiological controls.
o During NRC's review, in RWP 2022-0615, there were no written plans for
sequence and steps of the pressurizer heater removal. Poor planning resulted
in not maintaining doses ALARA. In RWP 2022-0512, the ALARA planning
phase did not account for the larger plane source of the new steam generator
design resulting in challenges with radiological exposures. Also, in the
planning of this RWP, the surveys used were from the mockup during the pre-
outage phase. When the radiological conditions changed, the licensee failed to
adjust the planned dose estimate to account for the higher dose rates during
the outage.
- Coordinating scheduling of work with radiation protection (RP) personnel to assure
work is completed in a manner and sequence that supports the ALARA Program.
o In NRC's review, there were examples of licensee groups not coordinating
activities, such as delays in staging material needed to conduct the work and
informal work plans. Activities and resources needed for work within the RCA
were not coordinated and accounted for appropriately. In the post-outage
review of RWP 2022-0512, the licensee deemed the delays in
staging/de-staging as the largest percentage of unproductive RWP person-
hours. In the post-outage review of RWP 2022-0615, the licensee stated that
the RP technicians supporting the activity did not have good firsthand
knowledge of the project scope and equipment being used which challenged
effective team building. Also, informal discussions between the project team
and RP staff for removal of the pressurizer heaters, in RWP 2022-0615,
resulted in uncertainty regarding the sequence and steps of execution.
Therefore, NRC determined that multiple procedural steps were missed during the planning
of these two work activities, RWP 2022-0512 and RWP 2022-0615, which resulted in
unplanned dose to workers and challenging ALARA principles.
Corrective Actions: The licensee addressed the deficiencies identified during the work activity
in their ALARA package post-job reviews. They also documented the failure to maintain
doses ALARA for these work activities in a new condition report for assessment of applicable
corrective actions.
Corrective Action References: CR-WF3-2023-16870
Performance Assessment:
Performance Deficiency: The licensee failed to follow ALARA planning procedures and did
not properly plan the scope of work activities.
Screening: The inspectors determined the performance deficiency was more than minor
because it was associated with the Program & Process attribute of the Occupational
Radiation Safety cornerstone and adversely affected the cornerstone objective to ensure the
adequate protection of the worker health and safety from exposure to radiation from
16
radioactive material during routine civilian nuclear reactor operation. Additionally, the finding
was similar to Example 6(i) in Appendix E to Inspection Manual Chapter 0612, Power
Reactor Inspection Reports - Examples of Minor Issues. This example states that an issue is
more than minor if it results in a collective dose greater than 5 person-Rem, and the actual
dose accrued exceeds the estimated dose by greater than 50 percent. Specifically, the actual
dose accrued for each work activity exceeded 5 rem and both exceeded the revised dose
estimate, as determined by the NRC, by 64 percent.
Significance: The inspectors assessed the significance of the finding using IMC 0609
Appendix C, Occupational Radiation Safety SDP. The inspectors determined the finding had
very low safety significance (Green) because: (1) it was associated with ALARA planning and
work controls; and (2) the licensees latest 3-year rolling average collective dose was less
than 135 person-Rem.
Cross-Cutting Aspect: H.4 - Teamwork: Individuals and work groups communicate and
coordinate their activities within and across organizational boundaries to ensure nuclear
safety is maintained. Specifically, the licensee failed to implement the process of planning
work activities with proper communication and coordination from each workgroup involved to
include person-hour estimates, resources, and formal work steps needed for the job activities.
This resulted in delays in staging material needed, inaccurate person-hours needed to
perform work activities, and uncoordinated resources needed for work activities.
Enforcement:
Violation: Technical Specification 6.8.1.a requires, in part, that written procedures shall be
established, implemented, and maintained covering the procedures recommended in
Regulatory Guide 1.33, Appendix A, Revision 2, dated February 1978. Section 7(e) of
Appendix A requires radiation protection procedures. Licensee Procedure EN-RP-110,
ALARA Program, revision 14, described the planning and scheduling responsibilities for
outage groups, which included providing accurate work site person-hours, providing detailed
work plans to allow ALARA planning to designate adequate radiological controls, and
coordinating scheduling of work with Radiation Protection personnel to support ALARA.
Contrary to the above, during refueling outage 24 in the spring of 2022, the licensee failed to
implement their ALARA program procedures for planning and controlling two work activities.
Specifically, for two RWPs-2022-0512 and -2022-0615, the licensee failed to provide
accurate work site person-hours, failed to provide detailed work plans for the pressurizer
heater removals or account for the larger plane source of the new steam generator design,
and failed to coordinate work activities and resources resulting in delays in staging materials
and unavailable resources. This resulted in not maintaining doses ALARA for workers during
these activities.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with
Section 2.3.2 of the Enforcement Policy.

The inspectors reviewed a self-revealed Green finding and associated NCV of 10 CFR 50.155(b)(1), which states, in part, strategies and guidelines to mitigate beyond -design-basis
events from natural phenomena must be capable of being implemented site-wide and must
include maintaining or restoring core cooling capabilities. Specifically, from approximately
February 14 to May 16, 2023, the licensee failed to ensure the starting batteries for the
FLEX N and N+1 diesel generators had sufficient capacity to perform their required
functions.
Description: As part of the licensees phase 2 strategies as required by NRC
Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation
Strategies for Beyond-Design-Basis External Events, the licensee committed to the guidance
described in NEI 12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation
Guide, revision 0. NRC Order EA-12-049 has since been codified by 10 CFR 50.155,
Mitigation of beyond-design-basis events.
Specifically for FLEX AC power supply, the licensee developed mitigating strategies that
utilize a FLEX N diesel generator as a 480V power supply that can be hooked up into a safety
bus. A FLEX N+1 diesel generator was stored outside the protected area as a backup that
can be brought into the protected area and connected into a safety bus. These two diesel
generators are the only dedicated means of providing 480V power for a beyond-design-basis
station blackout event. The diesel generators are started by a set of two commercial 8D
batteries for each generator.
On May 6, 2023, power was lost for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> to the FLEX N+1 building which maintains the
FLEX N+1 diesel generator starting battery charge. On May 13, 2023, the licensee was
performing weekly rounds when it was identified the control panel of the FLEX N+1 diesel
generator had no power. The capacity of the batteries was too low to restart the battery
charger to provide the float charge. The batteries would not have had the capacity to start the
FLEX N+1 diesel generator if needed. On May 14, 2023, the degraded starting batteries were
replaced with the charged and ready set of spare FLEX starting batteries.
On May 16, 2023, the licensee removed power to the FLEX N diesel generator for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for
maintenance. The power was reconnected 24 minutes later, and the licensee attempted to
start the FLEX N diesel. However, the generator failed to start due to degraded capacity of
the starting battery. In both failures, the cause was a starting battery that had degraded
capacity. Because there was a set of ready spare batteries that would be able to be changed
out in an actual event, the function of the FLEX AC power supply was not considered fully
lost. All FLEX functions could still be completed within the time allotted.
The licensee makes plans to replace the starting batteries on a 4-year frequency. No tests
are performed specifically on the batteries to ensure their capacity is adequate beyond
performing a start of the FLEX N and FLEX N+1 diesel generators every six months. Both
sets of starting batteries were purchased and installed in May 2020. There is no expected
lifetime of the battery provided by the manufacturer. The warranty on the batteries is for 6
months with a pro-rated replacement that extends until 30 months of life. As evidenced by the
failure to start of the diesel generators, the capacity of these starting batteries was degraded
beyond the ability to start the FLEX diesel generators.
The date on which the starting batteries had degraded to no longer be functional is unable to
be determined with accuracy. The degradation mechanism is not able to be identified on the
licensee weekly or monthly checks of the equipment. The previous successful surveillances
that started the FLEX N and N+1 diesel generators were on November 15, 2022. The
18
inspectors assume the degradation occurred halfway from the last successful surveillance to
when both FLEX diesel generators were repaired. This date was determined to be
February 14, 2023.
Corrective Actions: The licensee replaced the starting batteries for both FLEX N and
FLEX N+1 diesel generators. After the initial replacement, the licensee performed another
replacement with longer-lasting absorbed glass-mat batteries. Additionally, the licensee
implemented preventive maintenance to perform monthly battery load testing for the FLEX N
and FLEX N+1 diesel generator starting batteries.
Corrective Action References: CR-WF3-2023-13265, CR-WF3-2023-13293
Performance Assessment:
Performance Deficiency: The licensee failed to maintain mitigation strategies for beyond-
design basis external events.
Screening: The inspectors determined the performance deficiency was more than minor
because it was associated with the Equipment Performance attribute of the Mitigating
Systems Cornerstone and adversely affected the cornerstone objective to ensure the
availability, reliability, and capability of systems that respond to initiating events to prevent
undesirable consequences. Specifically, the licensee failed to maintain the FLEX N and
FLEX N+1 diesel generator batteries so their respective generators could start and provide
power in accordance with the licensee mitigating strategies.
Significance: The inspectors assessed the significance of the finding using IMC 0609
Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Using
Exhibit 2, Mitigating Systems Screening Questions, Section E, the inspectors determined
the finding to be of very low safety significance (Green), because the performance deficiency
was associated with equipment not solely purposed for spent fuel pool instrumentation or for
containment venting, but it was associated with equipment credited in a Phase 2 FLEX
strategy such that all FLEX functions could still be completed in accordance with existing
plant procedures within the time allotted.
Cross-Cutting Aspect: H.12 - Avoid Complacency: Individuals recognize and plan for the
possibility of mistakes, latent issues, and inherent risk, even while expecting successful
outcomes. Individuals implement appropriate error reduction tools. The licensee failed to
recognize and plan for the possibility of starting batteries to degrade faster than their service
life and result a loss of ability of the FLEX diesels to start.
Enforcement:
Violation: 10 CFR 50.155(b)(1), states, in part, strategies and guidelines to mitigate
beyond-design-basis events from natural phenomena must be capable of being implemented
site-wide and must include maintaining or restoring core cooling capabilities.
Contrary to the above, from approximately February 14 to May 16, 2023, the licensee failed
to maintain mitigation strategies for beyond-design basis external events. Specifically, the
licensee failed to maintain the FLEX N and FLEX N+1 diesel generator batteries so their
respective generators could start and provide power in accordance with the licensee
mitigating strategies.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with
Section 2.3.2 of the Enforcement Policy.

Observation: Flooded Lead-Acid Battery Performance 71152S
The inspectors reviewed the licensees corrective action program for potential adverse trends
in lead-acid battery performance that might be indicative of a more significant safety issue.
The inspectors observed a negative trend in performance and longevity of flooded lead-acid
battery performance. In addition to the FLEX N and FLEX N+1 starting battery issues detailed
in the IP 71152A section, the inspectors identified five other battery failures in 2023:
- CR-WF3-2023-01793: The starting batteries for the non-safety permanently-installed
temporary emergency diesel generator were degraded and unable to perform their
function.
- CR-WF3-2023-14593: The starting batteries for the security diesel generator were
degraded and unable to perform their function.
- CR-WF3-2023-15322: The starting battery for the portable ultimate heat sink
replenishment pump were below the required voltage.
- CR-WF3-2023-15407: The starting battery for the diesel-driven dry cooling tower
sump pump was degraded and unable to perform its function.
- CR-WF3-2023-15858: The starting batteries for diesel-driven fire pump A were
degraded and unable to perform their function.
These five diesel generators are considered non-safety but perform important functions
for the site. The licensee documented the NRC concern about a negative trend in
performance in CR-WF3-2023-15830 and performed an analysis of the issue. The
corrective actions included replacement of the batteries and a reconsideration of the
preventive maintenance strategies. No findings of significance were identified.
