PWR Inservice Inspection Activities Sample - Steam Generator Tube Inspection Activities

(Section 03.04)

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).

Steam Generator 1

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.

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.

12

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.

Failure to Follow ALARA Planning and Control Procedures Resulting in Unplanned Dose

Cornerstone Significance Cross-Cutting Report

Aspect Section

Occupational Green [H.4] - 71124.01

Radiation Safety NCV 05000382/2023004-02 Teamwork

Open/Closed

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,

13

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.

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

14

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.

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

15

  • 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

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

16

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.

Failure to Maintain FLEX Equipment Starting Batteries

Cornerstone Significance Cross-Cutting Report

Aspect Section

Mitigating Green [H.12] - Avoid 71152A

Systems NCV 05000382/2023004-03 Complacency

Open/Closed

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

17

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

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.

18

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.

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.
