                        Holtec Decommissioning International, LLC (HDI)
                              Pilgrim Nuclear Power Station (PNPS)
                    NRC Inspection Report No. 05000293/2020002 & 2020003
A period of announced decommissioning inspections was completed on September 30, 2020.
Onsite inspections were performed on July 13 - 16 and August 17 - 20, 2020. Remote
inspection activities were conducted throughout the period as a consequence of the COVID-19
public health emergency (PHE). The inspections included a review of the fire protection
program, inspection of dry fuel storage efforts, organization and management, safety reviews &
design changes, self-assessments, audits, corrective actions, spent fuel pool safety,
decommissioning performance and status, maintenance and surveillance, and occupational
radiation exposure. The inspections consisted of observations by the inspectors, interviews with
PNPS personnel, a review of procedures and records, and plant walkdowns. The NRC's
program for overseeing the safe operation of a shutdown nuclear power reactor is described in
Inspection Manual Chapter (IMC) 2561, Decommissioning Power Reactor Inspection Program."
Based on the results of this inspection, no findings of safety significance were identified.
                                                  ii
 
                                        REPORT DETAILS
1.0    Background
      June 10, 2019, Entergy Nuclear Operations, Inc. (ENOI) certified cessation of power
      operations and the permanent removal of fuel from the PNPS reactor vessel (ADAMS
      Accession Number: ML19161A033). This met the requirements of 10 Code of Federal
      Regulations (CFR) 50.82(a)(1)(i) and 50.82(a)(1)(ii). On June 11, 2019, the NRC
      notified PNPS that the Operating Reactor Assessment Program would terminate and
      that implementation of the Decommissioning Power Reactor Inspection Program would
      begin (ADAMS Accession No. ML19162A033). On August 27, 2019 an amended
      license was issued transferring the license from ENOI to Holtec International, LLC HDI
      (ADAMS Accession No. ML19235A050). PNPS is in active decommissioning with fuel in
      the spent fuel pool as described in IMC 2561.
2.0    Decommissioning Fire Protection Program
    a. Inspection Scope [Inspection Procedure 64704]
      The inspectors performed an inspection of Holtec Decommissioning Internationals
      (Holtec) Fire Protection Program (FPP) to determine if the program was sufficiently
      implemented and maintained to satisfy the nuclear safety and radioactive release goals,
      objectives, and performance criteria. The last performance of Inspection Procedure
      71111.05T, Fire Protection (Triennial), at Pilgrim was completed on November 1, 2018.
      The results of that inspection were documented in NRC Inspection Report
      05000293/2018015 (ADAMS Accession No. ML 18339A084). Except for changes to the
      onsite fire brigade and reliance on offsite fire emergency response organization(s) to
      respond to an onsite fire, no major changes had been implemented to the Pilgrim Fire
      Protection Program since that inspection. Therefore, the inspection was limited to
      reviewing the adequacy of the Fire Protection Program with respect to these changes.
      Per Regulatory Guide 1.191, Fire Protection Program for Nuclear Power Plants during
      Decommissioning and Permanent Shutdown, the licensee of a permanently shut down
      nuclear power plant is required by 10 CFR 50.48(f) to maintain a Fire Protection
      Program to address the potential for fires that could result in the release or spread of
      radioactive materials. The primary focus is protection of the integrity of the spent fuel
      and preventing or minimizing the release of radioactive materials resulting from fires
      involving contaminated plant systems or radioactive waste. To accomplish the
      inspection objectives, the inspectors utilized the guidance provided in Inspection
      Procedure 64704 and Regulatory Guide 1.191 and assessed the adequacy of the onsite
      incipient fire brigade and reliance on offsite fire emergency response organization(s) to
      respond to an onsite fire.
      Inspection of the adequacy of the overall Fire Protection Program will be coordinated
      when additional substantive changes have been made to support the decommissioning
      effort.
    b. Observations and Findings
      Based on the inspection results, the inspectors concluded that Holtec appropriately
      maintained the FPP related to the fire brigade within the NRC requirements of 10 CFR
                                                  1
 
      50.48(f) for plants undergoing decommissioning. Holtec maintained the leadership,
      staffing, and training of the onsite fire brigade. Agreements were appropriately
      established with the Town of Plymouth Fire Department, a fully staffed and professional
      fire department, to be the primary responder for onsite fires. Procedures for response
      and measures for coordination with offsite responders were appropriately established.
      The inspectors verified that Holtec conducted training with offsite responders on facility
      layout, fire hazards, fire plans, firefighting equipment, radiological hazards, and health
      physics relevant to firefighting operations. The inspectors confirmed that Holtec
      maintained applicable onsite firefighting equipment (e.g., fire pumps) and assured
      compatibility of the plants fire system connections with fire apparatus and equipment of
      the offsite responders.
c.    Conclusions
      No findings of significance were identified.
3.0  Independent Spent Fuel Storage Installation
3.1  Pre-operational Testing of an ISFSI (IP 60854)
  a. Inspection Scope
      On May 11-24, 2020, the inspectors performed a remote inspection (via teleconference
      and video-feed) of pre-operational dry-run activities that were performed in order to
      demonstrate proficiency in the implementation of a licensee procedure associated with
      drying multi-purpose canisters (MPC). This is a new procedure that incorporates the
      licensees transition from vacuum drying to the use of a Forced Helium Dehydration
      System (FHD) for the MPC. This procedure implements Engineering Change Order No.
      5014-295 and outlines performance of a reverse flow operation to reduce time required
      to meet the requirements of Certificate of Compliance (CoC) 72-1014, Amendment 12.
      In this change, the gas stream enters through the MPC drain access port and exits
      through the MPC vent access port.
      During the dry-run activities, the inspectors observed cask processing activities (via use
      of a mock MPC) to determine whether the Pilgrim staff and contractors had appropriately
      developed, implemented, and evaluated preoperational testing activities to safely
      process an MPC. This included observations of MPC blowdown, FHD, and helium
      backfilling.
      The inspectors also observed Pilgrim pre-job briefings to assess their ability to identify
      critical steps of the evolution, potential failure scenarios, and the use of human
      performance tools to prevent errors.
      The remote inspection was augmented through in-office review of the licensees 10 CFR
      72.212 report, records, and procedures provided for this portion of the inspection.
                                                  2
 
  b. Observations and Findings
    The inspectors noted that altering the direction of flow while drying the MPC contents did
    not affect ability of FHD to reach the CoC required drying or backfill limits.
    The inspectors noted the fuel basket of the MPC-68M (versus the previous MPC-68) is
    fabricated entirely from sectional Metamic (neutron absorbing material). This, combined
    with the use of fuel spacers, ensures that the active fuel region of fuel assemblies
    remains within the neutron-poison region of the MPC basket with water in the MPC.
    The MPC-68M fuel spacers have square flow holes that are one inch from the bottom of
    the basket. The previously-used MPC-68 fuel baskets had arced flow holes cut out of
    the bottom of the panels.
    During the dry-run with the new MPC-68M, a fuel assembly seating verification fit-up test
    was performed by inserting a test (i.e., non-fuel) bundle into five of the MPC fuel
    channels. In one of the channels, Pilgrim encountered an interference at the bottom of
    fuel channel F-5. Pilgrim temporarily ceased operation and entered the condition into
    their corrective action program as PIL-01627. To understand the scope of the issue, all
    channels were challenged with a test fuel bundle, and it was found that 30 spacers in the
    fuel basket had failed to seat properly. The cause was determined to be a result of the
    less ridged neutron-absorbing panels and different flow holes of the MPC-68M.
    To complete the dry-run, all MPC-68M fuel channels were re-tested and all fuel spacer
    fit-up issues were corrected. Pilgrim fabricated a testing-rod that is now used to verify
    that the proper channel length is present prior to loading a fuel bundle into that channel.
  c. Conclusions
    No findings of significance were identified.
3.2  Operation of an ISFSI at Operating Plants (IP 60855)
a.  Inspection Scope
    On May 18-15, 2020, the inspectors performed a remote inspection (via teleconference
    and video-feed) due to Covid-19 restrictions, to evaluate Pilgrims loading of their first of
    eleven MPCs of the 2020 dry fuel storage loading campaign. On July 13-16, 2020, the
    inspectors performed an onsite inspection to evaluate the loading of the ninth MPC.
    The inspections encompassed fuel transfer operations from the spent fuel pool to dry
    storage, using the HI-STORM 100 dry cask storage system.
    The inspections included:
          *    Cask No. 18 (MPC serial number 1021-685), HI-STORM Serial No. 1284, and
          *    Cask No. 26 (MPC serial number 1021-678), HI-STORM Serial No. 1276
          *
                                              3
 
  The inspectors reviewed several major updates to the dry fuel storage efforts, examined
  the HI-STORM 100 certificate of compliance No. 72-1014 (Amendment 12), and final
  safety analysis report (FSAR) Revision 17.
  The inspectors reviewed Pilgrims program associated with fuel characterization and
  selection for dry storage. The inspectors reviewed the first cask fuel selection package
  to verify that the licensee was loading fuel in accordance with the CoC, TS, and
  procedures. Inspectors reviewed a recording made of the fuel assemblies loaded into
  the first MPC to ensure the loading was in accordance with Pilgrims loading plan. The
  inspectors observed fuel assemblies being loaded into the MPC.
  The inspectors observed transport and submerging of the HI-TRAC/MPC into the spent
  fuel pool and onto the cask leveling platform. As part of this review the inspectors
  observed radiation protection technicians as they performed surveys, decontamination
  work and provided job coverage for the cask loading workers. This assessment included
  review of survey data maps and radiological records from the first MPC loading.
  The inspectors observed MPC processing activities, including helium backfill, hydrostatic
  testing, and helium leak testing of the vent and drain port covers. The inspectors
  observed the set-up of remote equipment (i.e., the robotic weld-head), hydrogen gas
  purge and monitoring, and MPC lid fit-up and welding. The inspectors observed weld
  surface pre-cleaning and drying, dye penetrant application, penetrant removal,
  developer application, and final weld assessment.
  The inspectors performed a walk-down of the heavy haul path and toured the ISFSI pad
  to assess the material condition of the pad and the HI-STORM modules. As part of the
  movement of the MPC and HITRAC, the inspectors observed HI-TRAC stack-up,
  download of MPC into the overpack, and transport of overpack with the loaded MPC to
  ISFSI Pad.
  The inspectors also reviewed the licensees planned activities associated with long-term
  operation and monitoring of the ISFSI.
  The inspectors reviewed corrective action reports and the associated follow-up actions
  that were generated during and after Pilgrims dry-run demonstrations to ensure that
  issues were entered into the corrective action program, prioritized, and evaluated in a
  manner that is commensurate with their safety significance.
b. Observations and Findings
  Dry fuel storage campaign activities were determined to be in compliance with the MPC-
  68M CoC, TS, regulatory requirements, and station procedures.
  The inspectors noted that welding procedure specifications were qualified in accordance
  with Holtec welding requirements, and that welders and personnel performing visual
  examination/NDE of welds were trained and certified under PCI Energy Services (an
  approved Holtec vendor).
  The inspectors noted that ISFSI staff maintained doses associated with dry cask
  activities as low as reasonably achievable (ALARA). The ionizing radiation exposure for
  the first MPC evolution was 1,465 mRem, and this was reduced to 803 mRem for the
                                            4
 
      eighth cask. This reduction was attributed to improvements in operations and
      appropriate adjustments as the campaign progressed.
      The inspectors also verified that transient combustibles were not being stored on the
      ISFSI pad or the vicinity of the HI-STORMS. The inspectors also confirmed that
      transient combustible materials entry onto the ISFSI pad was controlled in accordance
      with procedures.
c.    Conclusions
      No findings of significance were identified.
3.3    Review of 10 CFR 72.212(b) Evaluations (IP 60856)
a.    Inspection Scope
      The inspectors reviewed a Pilgrim 10 CFR 72.212(b) evaluation (Revision 5). This
      evaluation allowed the application of changes that were authorized by CoC 1014,
      Amendment 12 to a storage module that was previously loaded under the initial CoC
      1014, Amendment 7.
      The inspectors reviewed Holtecs evaluation of Engineering Change (EC) No. 82162,
      Dry Fuel Storage Licensing & Operations that addressed Phase 1 dry fuel storage
      (DFS) operations.
    b. Observations and Findings
      The inspectors verified that Pilgrim was in compliance with CoC 1014, Appendix A,
      Technical Specifications, and Appendix B, Approved Contents and Design Features"
      are applicable to the PNPS ISFSI. The inspectors also determined that the storage
      modules deployed at the PNPS ISFSI complied with all applicable terms, conditions, and
      specifications in Amendment 7 and/or 12 of HI-STORM CoC.
      The inspectors determined that an appropriate regulatory basis was used for loading and
      transporting eleven HI-STORM 100S Version B storage modules, containing MPC-68M
      canisters with spent fuel, to the lower ISFSI pad.
      Specifically, EC No. 82162 included adequate justification for a number of departures
      from prior DFS operations including; use of a new tracked vertical cask transporter,
      placement of HI-TRAC with empty MPC directly on rails, and installation/removal of the
      HI-STORM lid using a mobile crane. The EC also adequately addressed licensing
      requirements.
    c. Conclusions
      No findings of significance were identified.
                                                5
 
4.0  Decommissioning Performance and Status Review
  a. Inspection Scope [Inspection Procedures 36801, 37801, 40801, 60801, 62801, 71801,
    83750]
    The inspectors reviewed a sample of licensee commitments and requirements.
    The inspectors evaluated the contribution of the onsite safety review committee and the
    10 CFR 50.59 safety review process. The inspectors reviewed plant modifications and
    plans for any major decommissioning activities.
    The inspectors assessed Holtecs ability to identify, resolve, and prevent problems and
    deficiencies.
    The inspectors also reviewed spent fuel pool instrumentation, alarms, and leakage
    detection, and verified that Pilgrims wet spent fuel storage and handling controls were
    consistent with regulatory requirements and the applicable safety requirements.
    The inspectors evaluated the maintenance and surveillance programs to determine if
    they supported the safe storage of spent fuel and the reliable operation of radiation
    monitoring and effluent control equipment. The inspectors examined maintenance work
    priorities and backlog. The inspectors also conducted conference calls to discuss a
    historical issue with neutron absorbing materials in the spent fuel pool and how the
    facility is controlling heavy loads onsite.
    The inspectors attended a sampling of licensee meetings and verified that licensee
    activities were in accordance with licensed requirements. The inspectors performed a
    walkdown of the main control room and examined the controls and indicators that were
    currently available to the operating staff. The inspectors performed plant tours and
    observed the conduct of facility maintenance, repair, and operations. In addition, the
    inspectors reviewed the organization, experience, and staffing levels of the radiation
    protection (RP) organization.
    The inspectors examined the planning and authorization of radiation work and observed
    the conduct of radiological work and radiation protection technician work coverage. The
    inspectors also attended a pre-job briefing for removal of control rod drive mechanisms
    and observed the work inside the drywell. The inspectors observed the movement of an
    intermodal container that was posted and controlled as a locked high radiation area and
    also observed the cutting of local power range monitors on the refueling floor.
    The inspectors reviewed the Pilgrim programs for external radiation exposure monitoring
    and control, internal radiation exposure monitoring and control, radioactive
    contamination monitoring and control, and radioactive material control. The inspectors
    also reviewed Pilgrims programs for ionizing radiation exposure optimization.
b.  Observations and Findings
    The inspectors determined that the quality assurance organization conducted a program
    of audits and surveillances that were critical and intrusive, and that the organization was
                                                6
 
    active in the follow-up of previous audit observations and findings (in an effort to ensure
    effective resolution).
    The inspectors noted an active involvement by the Pilgrim site industrial safety
    representative in oversight of the site characterization efforts.
    The inspectors noted that the site safety review process did not explicitly call for the
    reviewer to screen any proposed program change for an impact on UFSAR accidents
    and accident analysis. The inspectors did further note that the current procedure did
    accomplish this by implication and that the process could be enhanced (and facilitate
    review and audit) by calling this out explicitly. This was discussed with the licensee
    during the inspection period.
    The inspectors determined that the pre-planning for removal of the control rod drive
    mechanisms, which can exhibit elevated radiation exposure levels, was extensive and
    effective in controlling the work in a safe and efficient manner.
c. Conclusions
    Based on the results of this inspection, no findings of safety significance were identified.
5.0 Exit Meeting Summary

REPORT DETAILS

1.0 Background

June 10, 2019, Entergy Nuclear Operations, Inc. (ENOI) certified cessation of power

operations and the permanent removal of fuel from the PNPS reactor vessel (ADAMS

Accession Number: ML19161A033). This met the requirements of 10 Code of Federal

Regulations (CFR) 50.82(a)(1)(i) and 50.82(a)(1)(ii). On June 11, 2019, the NRC

notified PNPS that the Operating Reactor Assessment Program would terminate and

that implementation of the Decommissioning Power Reactor Inspection Program would

begin (ADAMS Accession No. ML19162A033). On August 27, 2019 an amended

license was issued transferring the license from ENOI to Holtec International, LLC HDI

(ADAMS Accession No. ML19235A050). PNPS is in active decommissioning with fuel in

the spent fuel pool as described in IMC 2561.

2.0 Decommissioning Fire Protection Program

a. Inspection Scope [Inspection Procedure 64704]

The inspectors performed an inspection of Holtec Decommissioning Internationals

(Holtec) Fire Protection Program (FPP) to determine if the program was sufficiently

implemented and maintained to satisfy the nuclear safety and radioactive release goals,

objectives, and performance criteria. The last performance of Inspection Procedure

71111.05T, Fire Protection (Triennial), at Pilgrim was completed on November 1, 2018.

The results of that inspection were documented in NRC Inspection Report 05000293/2018015 (ADAMS Accession No. ML 18339A084). Except for changes to the

onsite fire brigade and reliance on offsite fire emergency response organization(s) to

respond to an onsite fire, no major changes had been implemented to the Pilgrim Fire

Protection Program since that inspection. Therefore, the inspection was limited to

reviewing the adequacy of the Fire Protection Program with respect to these changes.

Per Regulatory Guide 1.191, Fire Protection Program for Nuclear Power Plants during

Decommissioning and Permanent Shutdown, the licensee of a permanently shut down

nuclear power plant is required by 10 CFR 50.48(f) to maintain a Fire Protection

Program to address the potential for fires that could result in the release or spread of

radioactive materials. The primary focus is protection of the integrity of the spent fuel

and preventing or minimizing the release of radioactive materials resulting from fires

involving contaminated plant systems or radioactive waste. To accomplish the

inspection objectives, the inspectors utilized the guidance provided in Inspection

Procedure 64704 and Regulatory Guide 1.191 and assessed the adequacy of the onsite

incipient fire brigade and reliance on offsite fire emergency response organization(s) to

respond to an onsite fire.

Inspection of the adequacy of the overall Fire Protection Program will be coordinated

when additional substantive changes have been made to support the decommissioning

effort.

b. Observations and Findings

Based on the inspection results, the inspectors concluded that Holtec appropriately

maintained the FPP related to the fire brigade within the NRC requirements of 10 CFR

1

50.48(f) for plants undergoing decommissioning. Holtec maintained the leadership,

staffing, and training of the onsite fire brigade. Agreements were appropriately

established with the Town of Plymouth Fire Department, a fully staffed and professional

fire department, to be the primary responder for onsite fires. Procedures for response

and measures for coordination with offsite responders were appropriately established.

The inspectors verified that Holtec conducted training with offsite responders on facility

layout, fire hazards, fire plans, firefighting equipment, radiological hazards, and health

physics relevant to firefighting operations. The inspectors confirmed that Holtec

maintained applicable onsite firefighting equipment (e.g., fire pumps) and assured

compatibility of the plants fire system connections with fire apparatus and equipment of

the offsite responders.

c. Conclusions

No findings of significance were identified.

3.0 Independent Spent Fuel Storage Installation

3.1 Pre-operational Testing of an ISFSI (IP 60854)

a. Inspection Scope

On May 11-24, 2020, the inspectors performed a remote inspection (via teleconference

and video-feed) of pre-operational dry-run activities that were performed in order to

demonstrate proficiency in the implementation of a licensee procedure associated with

drying multi-purpose canisters (MPC). This is a new procedure that incorporates the

licensees transition from vacuum drying to the use of a Forced Helium Dehydration

System (FHD) for the MPC. This procedure implements Engineering Change Order No.

5014-295 and outlines performance of a reverse flow operation to reduce time required

to meet the requirements of Certificate of Compliance (CoC) 72-1014, Amendment 12.

In this change, the gas stream enters through the MPC drain access port and exits

through the MPC vent access port.

During the dry-run activities, the inspectors observed cask processing activities (via use

of a mock MPC) to determine whether the Pilgrim staff and contractors had appropriately

developed, implemented, and evaluated preoperational testing activities to safely

process an MPC. This included observations of MPC blowdown, FHD, and helium

backfilling.

The inspectors also observed Pilgrim pre-job briefings to assess their ability to identify

critical steps of the evolution, potential failure scenarios, and the use of human

performance tools to prevent errors.

The remote inspection was augmented through in-office review of the licensees 10 CFR

72.212 report, records, and procedures provided for this portion of the inspection.

2

b. Observations and Findings

The inspectors noted that altering the direction of flow while drying the MPC contents did

not affect ability of FHD to reach the CoC required drying or backfill limits.

The inspectors noted the fuel basket of the MPC-68M (versus the previous MPC-68) is

fabricated entirely from sectional Metamic (neutron absorbing material). This, combined

with the use of fuel spacers, ensures that the active fuel region of fuel assemblies

remains within the neutron-poison region of the MPC basket with water in the MPC.

The MPC-68M fuel spacers have square flow holes that are one inch from the bottom of

the basket. The previously-used MPC-68 fuel baskets had arced flow holes cut out of

the bottom of the panels.

During the dry-run with the new MPC-68M, a fuel assembly seating verification fit-up test

was performed by inserting a test (i.e., non-fuel) bundle into five of the MPC fuel

channels. In one of the channels, Pilgrim encountered an interference at the bottom of

fuel channel F-5. Pilgrim temporarily ceased operation and entered the condition into

their corrective action program as PIL-01627. To understand the scope of the issue, all

channels were challenged with a test fuel bundle, and it was found that 30 spacers in the

fuel basket had failed to seat properly. The cause was determined to be a result of the

less ridged neutron-absorbing panels and different flow holes of the MPC-68M.

To complete the dry-run, all MPC-68M fuel channels were re-tested and all fuel spacer

fit-up issues were corrected. Pilgrim fabricated a testing-rod that is now used to verify

that the proper channel length is present prior to loading a fuel bundle into that channel.

c. Conclusions

No findings of significance were identified.

3.2 Operation of an ISFSI at Operating Plants (IP 60855)

a. Inspection Scope

On May 18-15, 2020, the inspectors performed a remote inspection (via teleconference

and video-feed) due to Covid-19 restrictions, to evaluate Pilgrims loading of their first of

eleven MPCs of the 2020 dry fuel storage loading campaign. On July 13-16, 2020, the

inspectors performed an onsite inspection to evaluate the loading of the ninth MPC.

The inspections encompassed fuel transfer operations from the spent fuel pool to dry

storage, using the HI-STORM 100 dry cask storage system.

The inspections included:

  • Cask No. 18 (MPC serial number 1021-685), HI-STORM Serial No. 1284, and
  • Cask No. 26 (MPC serial number 1021-678), HI-STORM Serial No. 1276

3

The inspectors reviewed several major updates to the dry fuel storage efforts, examined

the HI-STORM 100 certificate of compliance No. 72-1014 (Amendment 12), and final

safety analysis report (FSAR) Revision 17.

The inspectors reviewed Pilgrims program associated with fuel characterization and

selection for dry storage. The inspectors reviewed the first cask fuel selection package

to verify that the licensee was loading fuel in accordance with the CoC, TS, and

procedures. Inspectors reviewed a recording made of the fuel assemblies loaded into

the first MPC to ensure the loading was in accordance with Pilgrims loading plan. The

inspectors observed fuel assemblies being loaded into the MPC.

The inspectors observed transport and submerging of the HI-TRAC/MPC into the spent

fuel pool and onto the cask leveling platform. As part of this review the inspectors

observed radiation protection technicians as they performed surveys, decontamination

work and provided job coverage for the cask loading workers. This assessment included

review of survey data maps and radiological records from the first MPC loading.

The inspectors observed MPC processing activities, including helium backfill, hydrostatic

testing, and helium leak testing of the vent and drain port covers. The inspectors

observed the set-up of remote equipment (i.e., the robotic weld-head), hydrogen gas

purge and monitoring, and MPC lid fit-up and welding. The inspectors observed weld

surface pre-cleaning and drying, dye penetrant application, penetrant removal,

developer application, and final weld assessment.

The inspectors performed a walk-down of the heavy haul path and toured the ISFSI pad

to assess the material condition of the pad and the HI-STORM modules. As part of the

movement of the MPC and HITRAC, the inspectors observed HI-TRAC stack-up,

download of MPC into the overpack, and transport of overpack with the loaded MPC to

ISFSI Pad.

The inspectors also reviewed the licensees planned activities associated with long-term

operation and monitoring of the ISFSI.

The inspectors reviewed corrective action reports and the associated follow-up actions

that were generated during and after Pilgrims dry-run demonstrations to ensure that

issues were entered into the corrective action program, prioritized, and evaluated in a

manner that is commensurate with their safety significance.

b. Observations and Findings

Dry fuel storage campaign activities were determined to be in compliance with the MPC-

68M CoC, TS, regulatory requirements, and station procedures.

The inspectors noted that welding procedure specifications were qualified in accordance

with Holtec welding requirements, and that welders and personnel performing visual

examination/NDE of welds were trained and certified under PCI Energy Services (an

approved Holtec vendor).

The inspectors noted that ISFSI staff maintained doses associated with dry cask

activities as low as reasonably achievable (ALARA). The ionizing radiation exposure for

the first MPC evolution was 1,465 mRem, and this was reduced to 803 mRem for the

4

eighth cask. This reduction was attributed to improvements in operations and

appropriate adjustments as the campaign progressed.

The inspectors also verified that transient combustibles were not being stored on the

ISFSI pad or the vicinity of the HI-STORMS. The inspectors also confirmed that

transient combustible materials entry onto the ISFSI pad was controlled in accordance

with procedures.

c. Conclusions

No findings of significance were identified.

3.3 Review of 10 CFR 72.212(b) Evaluations (IP 60856)

a. Inspection Scope

The inspectors reviewed a Pilgrim 10 CFR 72.212(b) evaluation (Revision 5). This

evaluation allowed the application of changes that were authorized by CoC 1014,

Amendment 12 to a storage module that was previously loaded under the initial CoC

1014, Amendment 7.

The inspectors reviewed Holtecs evaluation of Engineering Change (EC) No. 82162,

Dry Fuel Storage Licensing & Operations that addressed Phase 1 dry fuel storage

(DFS) operations.

b. Observations and Findings

The inspectors verified that Pilgrim was in compliance with CoC 1014, Appendix A,

Technical Specifications, and Appendix B, Approved Contents and Design Features"

are applicable to the PNPS ISFSI. The inspectors also determined that the storage

modules deployed at the PNPS ISFSI complied with all applicable terms, conditions, and

specifications in Amendment 7 and/or 12 of HI-STORM CoC.

The inspectors determined that an appropriate regulatory basis was used for loading and

transporting eleven HI-STORM 100S Version B storage modules, containing MPC-68M

canisters with spent fuel, to the lower ISFSI pad.

Specifically, EC No. 82162 included adequate justification for a number of departures

from prior DFS operations including; use of a new tracked vertical cask transporter,

placement of HI-TRAC with empty MPC directly on rails, and installation/removal of the

HI-STORM lid using a mobile crane. The EC also adequately addressed licensing

requirements.

c. Conclusions

No findings of significance were identified.

4.0 Decommissioning Performance and Status Review

a. Inspection Scope [Inspection Procedures 36801, 37801, 40801, 60801, 62801, 71801,

83750]

The inspectors reviewed a sample of licensee commitments and requirements.

The inspectors evaluated the contribution of the onsite safety review committee and the

10 CFR 50.59 safety review process. The inspectors reviewed plant modifications and

plans for any major decommissioning activities.

The inspectors assessed Holtecs ability to identify, resolve, and prevent problems and

deficiencies.

The inspectors also reviewed spent fuel pool instrumentation, alarms, and leakage

detection, and verified that Pilgrims wet spent fuel storage and handling controls were

consistent with regulatory requirements and the applicable safety requirements.

The inspectors evaluated the maintenance and surveillance programs to determine if

they supported the safe storage of spent fuel and the reliable operation of radiation

monitoring and effluent control equipment. The inspectors examined maintenance work

priorities and backlog. The inspectors also conducted conference calls to discuss a

historical issue with neutron absorbing materials in the spent fuel pool and how the

facility is controlling heavy loads onsite.

The inspectors attended a sampling of licensee meetings and verified that licensee

activities were in accordance with licensed requirements. The inspectors performed a

walkdown of the main control room and examined the controls and indicators that were

currently available to the operating staff. The inspectors performed plant tours and

observed the conduct of facility maintenance, repair, and operations. In addition, the

inspectors reviewed the organization, experience, and staffing levels of the radiation

protection (RP) organization.

The inspectors examined the planning and authorization of radiation work and observed

the conduct of radiological work and radiation protection technician work coverage. The

inspectors also attended a pre-job briefing for removal of control rod drive mechanisms

and observed the work inside the drywell. The inspectors observed the movement of an

intermodal container that was posted and controlled as a locked high radiation area and

also observed the cutting of local power range monitors on the refueling floor.

The inspectors reviewed the Pilgrim programs for external radiation exposure monitoring

and control, internal radiation exposure monitoring and control, radioactive

contamination monitoring and control, and radioactive material control. The inspectors

also reviewed Pilgrims programs for ionizing radiation exposure optimization.

b. Observations and Findings

The inspectors determined that the quality assurance organization conducted a program

of audits and surveillances that were critical and intrusive, and that the organization was

6

active in the follow-up of previous audit observations and findings (in an effort to ensure

effective resolution).

The inspectors noted an active involvement by the Pilgrim site industrial safety

representative in oversight of the site characterization efforts.

The inspectors noted that the site safety review process did not explicitly call for the

reviewer to screen any proposed program change for an impact on UFSAR accidents

and accident analysis. The inspectors did further note that the current procedure did

accomplish this by implication and that the process could be enhanced (and facilitate

review and audit) by calling this out explicitly. This was discussed with the licensee

during the inspection period.

The inspectors determined that the pre-planning for removal of the control rod drive

mechanisms, which can exhibit elevated radiation exposure levels, was extensive and

effective in controlling the work in a safe and efficient manner.

c. Conclusions

Based on the results of this inspection, no findings of safety significance were identified.

5.0 Exit Meeting Summary

On November 9, 2020, the lead inspector presented the inspection results to

Mr. John Moylan, Site Vice President, and other members of the HDI staff. No

proprietary information was retained by the inspectors or documented in this report.
