2690 2690-01 PURPOSE To establish the U.S. Nuclear Regulatory Commissions (NRC) inspection program for independent spent fuel storage installations (ISFSIs), dry storage systems (DSSs), and transportation packagings.

2690-02 OBJECTIVES 02.01 To establish the general policy and responsibilities for the inspection of ISFSIs, DSSs, and transportation packagings.

02.02 To define the program for inspections related to ISFSIs, the design, fabrication, and testing of DSSs, and the design, fabrication, testing, and maintenance of transportation packagings to ensure that these activities do not pose an undue risk to public health and safety.

02.03 To establish a consistent process of inspection to ensure the health and safety of workers and the public, protect the environment, and promote the common defense and security.

2690-03 DEFINITIONS ISFSI. An independent spent fuel storage installation (ISFSI) is a complex designed and constructed for the interim storage of spent nuclear fuel, solid reactor-related greater-than-Class C (GTCC) waste, and other radioactive materials associated with spent fuel and reactor-related GTCC waste storage. An ISFSI which is located on the site of another facility licensed under Title 10 of the Code of Federal Regulations (10 CFR) Part 72 or a facility licensed under 10 CFR Part 50, and which shares common utilities and services with that facility or is physically connected with that other facility may still be considered independent. Generally, GTCC casks are loaded under the guidance of Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program and IMC 2561, Decommissioning Power Reactor Inspection Program, however monitoring is performed under this IMC.

DSS. Dry storage system (DSS) is the term used to describe the physical system, either a cask or a canister in its shielding overpack, which holds the spent fuel and is a component of the ISFSI. An ISFSI may contain several different DSS designs.

For this inspection program, four different entities will be discussed.

a. Licensee. An organization that is operating an ISFSI for the storage of spent fuel and other radioactive materials associated with spent fuel under a 10 CFR Part 72 license.

Licensees are of two types, specific and general and are ultimately responsible for ensuring that the ISFSI is designed, fabricated, constructed, and operated in accordance with the requirements contained in 10 CFR Part 72 and the specific license or the general license Certificate of Compliance (CoC). The licensee may also fabricate DSS components or construct ISFSI structures, such as the storage pad.

b. Vendor. An organization, typically independent from the licensee, that is responsible for the design of a particular DSS and ensuring that design commitments contained in the safety analysis report (SAR) are met during the fabrication of the DSS. For a general license ISFSI, the vendor is also typically the CoC holder for the DSS. For a specific license ISFSI, there is no CoC, and the SAR contains the relevant information on the

Issue Date: 10/16/24 2

2690 design and fabrication of the DSS. Regardless of the type of license, the vendor is also responsible for ensuring that the DSS is designed and fabricated in accordance with applicable requirements.

c. CoC Holder. A vendor that has obtained NRC approval for a specific DSS under 10 CFR Part 72, Subpart L. The issuance of a CoC to the vendor authorizes the use of the DSS in an ISFSI under the general license.

d. Fabricator. An organization that is physically building the DSS components and receives design oversight from either the vendor, licensee, or both. The fabricator is responsible for manufacturing the DSS in accordance with the vendors requirements and drawings.

Away-From-Reactor (AFR). An AFR is a 1) specifically licensed ISFSI whose associated support programs are not conducted under a 10 CFR Part 50 license, or 2) any generally licensed ISFSI where decommissioning and final survey activities related to reactor operations are completed and the only remaining operation conducted under the 10 CFR Part 50 license is the operation of the general licensed ISFSI.

Integrated Inspection Plan (IIP). An integrated inspection plan (IIP) is a document developed and approved by a regional branch chief for each new ISFSI site and for any site switching dry cask storage systems (see Section 05.06). The IIP provides supplemental guidance for planning and scheduling the numerous inspections and any technical reviews that are required before initial loading of spent fuel into the ISFSI. The IIP is intended to ensure that adequate resources are applied to perform the necessary inspections before initial loading of spent fuel into the ISFSI.

Inspection Frequencies

a. When Required. The inspection effort should be performed when the activity or event occurs at the facility as specified in Appendix A or B.

b. Quarterly. The inspection effort will be performed once each calendar quarter.

c. Triennial. The inspection will be performed at least once during Reactor Oversight Process (ROP) cycles 1-3, ROP cycles 4-6, ROP cycles 7-9, etc. It is intended for this to be based on a rolling 3-year cycle. See IMC 2515 Attachment 1 for ROP cycles.

Period of Extended Operation (PEO). The period of extended operation is the period (e.g., 20 or 40 years) commencing immediately after the expiration of a licensees or CoC holders initial license or CoC, respectively. Examples of determining the PEO are provided in 76 Federal Register 8890, February 16, 2011.

Deviation Deviations are defined as not completing all inspection procedure requirements as defined in the individual inspection procedure or not completing the inspection procedure within the required frequency as defined in Appendix A or B of this IMC.

Very Low Safety Significance Issue Resolution Process (VLSSIR Process) A process used to discontinue inspection of an issue involving an unresolved licensing basis question in which (1) the resolution of the issue would require considerable staff effort; and (2) the agency has chosen to not expend further effort to resolve the question because the issue would be no greater than green under the ROP or severity level (SL) IV under the traditional enforcement process if it were determined to be a violation.

05.03 Risk-Informed Safety Focus Areas Items that result in unintended radiological exposure, damage to the fuel, a confinement breach, or impact an operating plant are unacceptable and are considered risk significant. Fuel damage and canister breach could place the canister into an unanalyzed condition. Inspectors shall review items associated with the below five risk-informed safety focus areas to determine if licensee performance provides reasonable assurance of adequate protection.

a. Occupational exposure

b. Public exposure

c. Fuel management

d. Confinement/canister integrity

e. Impact to plant operation

Issue Date: 10/16/24 6

2690 These focus areas were chosen to address potential issues of greatest safety significance for a dry cask storage program. The occupational and public exposure focus areas encompass the direct impact of dry cask operations on workers and the public. The fuel management and confinement/canister integrity focus areas are those that encompass radiological barriers to workers and the public. The impact to plant operation focus area encompasses activities that may impact site operations and the core damage frequency and large early release frequency (LERF) risk metrics of the NRCs Safety Goal Policy for operating reactors.

Appendix D Guidance for Risk-Informed Inspection Prioritization, of this IMC provides detailed guidance for the prioritization of inspection activities at ISFSIs. Appendix E Guidance for Risk-Informed Review of 72.48 Evaluations, of this IMC provides detailed guidance for the prioritization of review of 10 CFR 72.48 evaluations at ISFSIs, vendors, and fabricators.

05.04 Planning, Scheduling, and Tracking of Inspection Activities Each region shall, at a minimum, use RRPS for planning, scheduling, and recording of completed inspections of ISFSI activities. The Regional Branch Chief should maintain a three-year rolling inspection schedule to aid in the determination of required Full Time Equivalent (FTE) resources needed to successfully implement inspection program requirements. To determine resource needs, inspectors should maintain frequent communication with their licensees. A Technical Assistance Request (TAR), for example, may take six months or more to resolve. If its known that a TAR or other significant assistance will be needed, the inspector should strive to identify these needs as early as possible through periodic communication with their licensees.

05.05 DFM Scheduling of Vendor and Fabricator Inspections The scheduling of vendor and fabricator inspections should consider vendor or fabricator performance and recent vendor or fabricator inspections performed for other ISFSI licensees. Additional inspections may be conducted as required. The DFM will inform any affected regions of the schedule for inspecting vendors or fabricators and any schedule changes as soon as the need for the change is identified. The DFM will inform the applicable region of any fabricator inspections at general or specific licensee sites.

05.06 Integrated Inspection Plan For a new specific or general license ISFSI site being constructed, or for any change in DSS type, the applicable Regional Branch Chief, with input and assistance from the DFM if desired, shall develop an IIP in accordance with the guidance listed below.

a. For new ISFSI sites, all IPs shall be performed as identified in the IIP. For sites switching dry cask storage systems, a gap analysis shall be performed to determine which IPs or portions of IPs should be performed.

b. The IIP should indicate licensee milestones, planned inspection dates, inspection procedures to be used, and inspection resources needed.

2690 05.07 Applicability of Very Low Safety Significance Issue Resolution Process (VLSSIR)

The VLSSIR process as described below is applicable to the Office of Nuclear Material Safety and Safeguards business lines.

NOTE: The VLSSIR process cannot be used to resolve known compliance issues, issues where there is a clear indication that a noncompliance occurred but certain details concerning the issue have not been finalized (e.g., specific date, time, location), nor should it be used to establish a staff position.

In some cases, an inspector may identify an issue that results in an unresolved licensing basis question which may take staff considerable effort to resolve. In the context of VLSSIR, the term licensing basis refers to all regulations, license conditions, and requirements applicable to a facility or licensee, including, but not limited to, the licensees written commitments for ensuring compliance. In determining how to proceed, the inspector should consider the significance of the facility or licensee, including, but not limited to, the licensees written commitments for ensuring compliance. In determining how to proceed, the inspector should consider the significance of the issue.1 The inspector should refer to the guidance available in IMC 0610, Appendix G, Screening and Documentation of Very Low Safety Significance Issue Resolution Process, to determine if the issue is no greater than severity level (SL) IV if determined to be a non-compliance.2 If the issue is no greater than SL IV, further evaluation of the issue can be discontinued using the VLSSIR process. If further inspection of the issue cannot be discontinued using the VLSSIR process, then resolution of the issue should be continued following existing processes, including the identification of an unresolved issue and/or use of the headquarters technical support for regional activities, e.g.,

Technical Assistance Request (TAR) process.

If inspection of an issue is discontinued using the VLSSIR process, no further staff effort to resolve the issue is necessary. Documentation of the issue, in accordance with IMC 0610, Appendix G, and IMC 0611, as appropriate, should provide an appropriate level of inspection closure, knowledge management, and transparency.

Issues identified associated with the 10 CFR Part 50 license and not the 10 CFR Part 72 license should utilize the guidance associated with the VLSSIR process identified in IMC 0612.

Once a VLSSIR is documented the staff should generally refrain from spending additional inspection resources on the issue.

05.08 Regional Inspection Reports Inspections conducted at operating reactor sites shall be documented in accordance with Section 13.02 of IMC 0611, Power Reactor Inspection Reports. Inspection reports at 1 Although the definition for VLSSIR refers to "safety significance," the VLSSIR process applies to a broad range of regulated areas related to safety, including security, emergency planning and preparedness, documentation control, and reporting.

2 IMC 0610, Appendix G, is being updated to incorporate guidance on the application of the VLSSIR process. In the meantime, staff may use the interim staff guidance provided in the NMSS OD memo on VLSSIR process application by materials business lines (ML22353A599), to determine if the issue is no greater than SL IV.

Issue Date: 10/16/24 8

2690 operating reactor sites normally should be integrated into the resident inspectors quarterly report. All other inspections will be documented similar in scope to operating reactor site reports in accordance with IMC 0610, Nuclear Material Safety and Safeguards Inspection Reports. Inspection reports shall contain the relevant 10 CFR Part 72 docket number and, for specific licensees, the license number. These reports shall be transmitted to licensees in accordance with regional requirements as appropriate.

Inspection findings at operating reactor sites that are related to operating reactor equipment, or a ROP program or process shall be evaluated consistent with guidance in IMC 0612, Issue Screening and for cross cutting aspects as appropriate. Traditional enforcement is used for ISFSI-specific activities to ensure consistent NRC enforcement decisions whether the site is under an operating power reactor, decommissioning power reactor, or AFR inspection program.

When documenting the VLSSIR process application, inspectors may use the Reactor Program Systems (RPS) to save and manage inspection reports and supporting information. The RPS already has a search capability and a utility that the staff can use to track use and entries into the system, including any VLSSIR use/entries.

05.09 Headquarters Inspection Reports Inspections led by Headquarters shall be documented using a narrative report format in accordance with the guidance in IMC 0610 and IMC 0617, as applicable. Inspectors shall consider the guidance in IMC 0610 when evaluating inspection findings. Inspectors may also refer to the guidance in IMC 0617, Appendix E, as applicable, when evaluating inspection findings to determine if they have more than minor safety significance.

Inspection reports shall contain the relevant 10 CFR Part 72 and/or Part 71 docket number(s). These reports shall be transmitted to licensees in accordance with Headquarters requirements as appropriate.

When documenting the VLSSIR process application, inspectors may use the Reactor Program Systems (RPS) to save and manage inspection reports and supporting information. The RPS already has a search capability and a utility that the staff can use to track use and entries into the system, including any VLSSIR use/entries.

05.10 Enforcement Action Follow-up If a licensee has open items resulting from traditional enforcement including violations, deviations, Confirmatory Action Letters (CALs), Confirmatory Orders, and Confirmatory Orders associated with the Alternative Dispute Resolution (ADR) process; inspectors shall review and disposition the items in accordance with the NRC enforcement policy and manual. Any in-office or on-site inspection or follow-up review should be conducted in accordance with the appropriate inspection procedure including IP 92702, Follow-up on Traditional Enforcement Actions Including Violations, Deviations, Confirmatory Action Letters, Confirmatory Orders, and Alternative Dispute Resolution Confirmatory Orders, IP 92722, Follow Up Inspection for Any Severity Level I or II Traditional Enforcement Violation or for Two or More Severity Level III Traditional Enforcement Violations in a 12 Month Period, and IP 92723, Follow Up Inspection for Three or More Severity Level IV Traditional Enforcement Violations in the Same Area in a 12-Month Period.

Issue Date: 10/16/24 9

2690 05.11 Management Entrance and Exit Meetings Inspectors are required to meet with licensee management as part of every inspection.

Inspectors should hold an entrance and exit meeting with the senior licensee representative who has responsibility for the areas to be inspected. Each inspection conducted must include discussing inspection results with licensee management. At the conclusion of an inspection, inspectors must discuss their preliminary findings with the licensees management. Additional expectations and requirements on the conduct of entrance and exit meetings can be found in IMC 2515-12, Section 12.01, Management Entrance and Exit Meetings.

05.12 Review of Open Allegations Inspectors (DFM and region-based) shall review all open allegations pertaining to areas which they will be inspecting as part of their inspection preparation. The purpose of this review is to allow the inspectors to become aware of concerns in the areas which they may be inspecting. However, all qualified inspectors should be cognizant of the procedures to follow in the event any allegation (even if it is outside their area of expertise) is disclosed to them and shall follow the direction of the Allegation Review Board, and the requirements of Management Directive 8.8, Management of Allegations.

05.13 Witnessing Unsafe Conditions A goal of the NRC inspection program is to witness licensee activities in as close to a normal environment as possible. From the assessment of these observations, conclusions are drawn relative to the licensee's ability to properly conduct licensed activities. Notwithstanding this goal, under no circumstances will an NRC inspector knowingly allow an unsafe work practice or a violation which could lead to an unsafe situation to occur or continue in his/her presence to provide a basis for enforcement action. When NRC personnel identify unsafe work practices or violations which could lead to an unsafe situation, they shall make every reasonable attempt to prevent them from occurring or continuing in their presence. When such situations are identified, a licensee representative shall promptly be notified so that corrective or preventive measures can be taken. This action shall be taken without regard for any impact it may have on the ability of the NRC to take future enforcement action.

05.14 Inspector Qualification Safety inspection of activities associated with ISFSIs (e.g., DSS fabrication, support pad construction, loading and unloading procedures) shall be performed by qualified inspectors in accordance with IMC 1246, Appendix B3, Training Requirements and Qualification Journal for Independent Spent Fuel Storage Installation Inspector, or IMC 1246, Appendix B2, Training Requirements and Qualification Journal for Spent Fuel Storage and Transportation Inspector, as appropriate. Training requirements for inspectors qualified under IMC 1245, Appendix C1, Reactor Operations Inspector Technical Proficiency Training and Qualification Journal, IMC 1245, Appendix C2, Reactor Engineering Inspector Technical Proficiency Training and Qualification Journal, or IMC 1245 Appendix C3, Health Physics Inspector Technical Proficiency Training and Qualification Journal is provided in IMC 1246, Appendix B3. If expertise is needed from a non-ISFSI qualified individual, see Section 05.15 for additional guidance.

Issue Date: 10/16/24 10 2690 Safety inspection of activities associated with transportation packagings (e.g., package design, fabrication, and maintenance) shall be performed by qualified inspectors in accordance with IMC 1246, Appendix B2, Training Requirements and Qualification Journal for Spent Fuel Storage and Transportation Inspector.

Security inspection of activities associated with ISFSIs shall be performed by qualified inspectors in accordance with IMC 1245, Appendix C13, Independent Spent Fuel Storage Installation Security Inspector Technical Proficiency Training and Qualification Journal, or IMC 1246, Appendix B4, Independent Spent Fuel Storage Installation Security Inspector Technical Proficiency Training and Qualification Journal.

05.15 Coordination of Technical Support for Inspection Activities Inspectors are technically qualified in the areas in which they inspect, though there are instances where inspectors may seek different levels of technical guidance or assistance in inspection activities. This may include seeking support from Headquarter (HQ) technical staff or regional inspectors with specific areas of expertise. Inspectors should consider reaching out to their peers in the other Regions as a resource to discuss inspection related questions and concerns. Its possible, similar questions or concerns have been previously raised or addressed in another Region. Collaborating with inspectors across the Regions assists with effective and efficient oversight. Additionally, each Region possesses inspectors with expertise in a breadth of topics. Although HQ or regional experts might not be qualified ISFSI inspectors, they can be used as a resource for specific topics related to health physics, structures, security, fire protection, emergency preparedness, quality assurance, etc. If these experts are used to assist on an ISFSI inspection, they must be supervised by a fully qualified ISFSI inspector and are subject to Regional Branch Chief approval.

It is important that the inspectors and the technical support staff clearly communicate the context for the questions along with the questions themselves, and the level of support the inspectors are seeking. Whatever the level of support, the inspectors must make it clear what the expectations are for the support they are seeking. The time spent supporting an inspection needs to be captured to the appropriate Cost Activity Code CAC/EPID and the requesting and supporting organization(s) should align on where the time will be charged (inspection or an inspection support CAC). The following guidelines are for requests to HQ which are seeking to understand and to inform documents developed, finalized, and approved by the inspecting organization.

a. Minimal Effort Needed (< 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />): Inspectors have a question in a technical area they are inspecting (or preparing to inspect) and contact a technical point of contact in the region (could be an ISFSI inspector in another region or other regional inspector as described above) or HQ with specific questions. These occur frequently and typically take minutes to a couple of hours to respond. The time and level of support efforts are self-managed between the inspector and HQ staff. A response from HQ staff to the inspectors is typically verbal or via email. When a technical staff member is directly contacted by an inspector, its reasonable and acceptable for that staff member to respond that they are unable to support given their current workloads. If thats the case, the inspector should continue to elevate the request for help through the following steps, as necessary.

b. Slightly More Effort Needed (4 - 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />): Inspectors have a complex question or set of questions that may take more than a few hours for the technical staff to respond to.

Issue Date: 10/16/24 11 2690 The inspectors and HQ technical staff should discuss the level of effort needed for a response. The time and level of support efforts are managed by the inspection and HQ staff with HQ branch chief permission (as indicated above, inspectors must respect the technical staffs time and work priorities). As an initial step, the IOB Branch Chief serves as the DFM point of contact with the regions in assessing technical support needs of the region. A response from HQ staff to the inspector is verbal or via email.

c. Request for Direct Support Throughout an Inspection (> 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> up to the duration of the inspection): Occasionally, an inspection team leader determines the need for HQ technical experts to support their inspection, either remotely or directly onsite throughout the inspection. When this occurs, the inspectors must request the technical staff participation through their branch chief to the IOB Branch Chief, due to the significant amount of time needed. The IOB Branch Chief will determine whether IOB has the resources and expertise to assist in resolving the concern or will coordinate with the other Chiefs in DFM if appropriate. To assist with planning, inspectors should strive to identify and communicate these needs approximately 12 months prior to needing assistance.

Occasionally, when routine channels are exhausted for resolving an issue, or the issue has become protracted or progress has stalled, or for requests that may take more than a reasonable amount of time (as agreed between the inspector/technical staff and their supervisors), then the inspectors must use a formal process such as a TAR or a formal request memorandum, since this is expected to be a significant resource commitment.

Examples include providing a basis to dispute a licensee position, or a technical determination stemming from the inspection efforts to make a final inspection determination, or requires other expertise (e.g., civil engineering for pad design reviews, structural for stack-up reviews, legal interpretations, etc.). Given the amount of time it takes to resolve TARs, it is preferred to identify and notify the IOB Branch Chief as early as practicable regarding the possibility of a TAR.

Issue Date: 10/16/24 14 2690 Appendix A: Inspection Program Guidance for ISFSIs 2690A-01 SCOPE This appendix describes the inspection program for CoC Holders and Fabricators of DSS SSCs.

This appendix also describes the inspection program for ISFSI activities authorized under the provisions of a general or specific license including those associated with a 10 CFR Part 50 reactor site and whose support programs are being conducted under the reactor sites 10 CFR Part 50 license.

The NRC staff should evaluate whether additional IPs not specified in Appendix A should be performed in coordination with DFM when generating an IIP for specific license ISFSIs not associated with a 10 CFR Part 50 license to ensure adequate oversight.

Guidance is provided on the scheduling and conduct of inspections during various phases of ISFSI activities: design, fabrication, and construction; preoperational testing; loading and unloading; and storage monitoring including the period of extended operation.

Most inspections are conducted on-site using direct observations and performing on-site reviews of documentation and interviews with personnel. Where appropriate, supplementing on-site with remote inspection techniques may be used when warranted, e.g., document reviews, interviews. Direct observation shall be regarded as the preferred method of inspection. Remote inspection of activities that are normally directly observed should be considered only in rare or unusual circumstances and headquarters or regional management approval must be received, as applicable. Partial remote inspections may be approved by branch chiefs, but full remote inspections shall be approved by division management. For the purposes of this Appendix, ISFSI activities are viewed as occurring in the following four phases: (Phase activities may occur concurrently)

a. Phase 1: Design, fabrication, and DSS construction

b. Phase 2: Pad construction and preoperational testing

c. Phase 3: Spent fuel loading, unloading and routine storage operations

d. Phase 4: Storage monitoring at an AFR.

2690A-02 INSPECTION FREQUENCIES The following sections indicate initial no-later-than (NLT) dates for each IP. These dates indicate the first instance each inspection shall be completed for each new ISFSI, CoC holder or fabricator. Once the initial inspection has been performed for each new ISFSI, CoC holder or fabricator, inspections shall continue in accordance with the indicated frequency until licensed activities cease.

CONDUCT OF PHASE 1 - DESIGN, FABRICATION AND DSS CONSTRUCTION Phase 1 inspections are performed by DFM/IOB of CoC holders and their DSS fabricator(s).

Additional inspection guidance for the conduct of Phase 1 inspections is in NUREG/CR-6314, Quality Assurance Inspections for Shipping and Storage Containers.

Issue Date: 10/16/24 15 2690 Table A-1 IP SUBJECT INITIAL NLT FREQUENCY 60851 Design control of ISFSI components Beginning of initial DSS fabrication Every three years3 60852 ISFSI component fabrication by outside fabricators Completion of initial DSS fabrication1 Every three years while fabrication activities are ongoing3 60853 On-Site fabrication of components and construction of an ISFSI Completion of initial DSS onsite construction2 Every three years while construction activities are.

ongoing3 60857 Review of 10 CFR 72.48 evaluations As needed to support above IPs As needed to support above IPs 1 Note: If several casks are being fabricated at one time, then the milestone associated with IP 60852 should be completed before the fabricator finishes manufacturing the last of that series of casks. These inspection requirements apply to each fabricator and/or fabrication facility.

Consideration should be given to inspect fabrication of new DSS designs being fabricated if outside of the routine inspection frequency, dependent on the scope and significance of the design changes from previous designs.

2 Note: Only Inspection Requirements of IP 60853 Sections 02.01, 02.02, and 02.03 are performed during Phase 1 inspections. This applies only to the DSS vendors performing construction activities onsite at general or specific licensee facilities.

3 Note: The inspection frequency may be extended to the end of the corresponding fiscal year.

CONDUCT OF PHASE 2 - PAD CONSTRUCTION AND PREOPERATIONAL TESTING Phase 2 inspections are performed by the Regional Offices on general or specific ISFSI licensees. For ISFSIs associated with a 10 CFR Part 50 reactor site, if the licensee credits the 10 CFR Part 50 programs (e.g., quality assurance, safety evaluations, radiation protection, emergency preparedness, or security) that support operation of the ISFSI, the programs are reviewed under the IMC 2515 inspection program. Consequently, for an ISFSI associated with a 10 CFR Part 50 reactor site, the IMC 2690 inspection program is primarily directed at verifying that activities related to the ISFSI have been properly incorporated into the existing licensee programs such that a full reinspection of the licensees or applicants programs is not required.

These inspections set the baseline for future safe loading and monitoring operations.

Selected IPs should be re-performed if a licensee intends to use a new model DSS, when a separate DSS is already in use at the same ISFSI. Additionally, selected IPs should be re-

Issue Date: 10/16/24 16 2690 performed if a licensee intends to construct a new ISFSI pad when an existing ISFSI pad is already in use at the same ISFSI. A gap assessment should be performed to determine the level of inspection and timeliness for the new activity. If assistance is needed in performing the gap assessment, the Regional Office should contact DFM for assistance.

Table A-3 IP SUBJECT INITIAL NLT FREQUENCY 60855 Operation of an ISFSI Initial Cask Loading Triennial (Quarterly During Continuous Offload, All DSS Unloading Activities)1,2 60857 Review of 10 CFR 72.48 evaluations As needed to support above IP As needed to support IPs 60859 Independent Spent Fuel Storage Installation (ISFSI) License Renewal Inspection Once when a licensee enters the period of extended operation at the first available opportunity not to exceed the end of the next triennial inspection period Once for each storage system located at an ISFSI site3 81311 Physical security requirements for ISFSIs Within 3 years of initial cask loading4 Once every 3 years4 1Note: Continuous Offload. When a site, typically after permanent cessation of operations, performs a continuous loading campaign with the intent of offloading the spent fuel pool.

2Note: All unloading activities shall be inspected or as determined by DFM.

3Note: For awareness, some ISFSI sites may have more than one aging management program (AMP) based on the type of storage systems and the type of licenses used at the facility. For example, if a site has a specific license and a general license with different types of storage systems, than there could be as many as four AMPs. However, the inspection staff will only need to conduct one baseline inspection for that ISFSI site.

4Note: Not required for ISFSIs within an operating reactors protected area. These ISFSIs are inspected in accordance with IMC 2201, Security Inspection Program for Operating Commercial Nuclear Power Reactors.

Issue Date: 10/16/24 17 2690 CONDUCT OF PHASE 4 - STORAGE MONITORING AT AN AFR Phase 4 inspections are performed by the Regional Offices on General or Specific ISFSI licensees.

An AFR ISFSI is defined in Section 03.04 and the facility does not, or no longer receives oversight from another NRC inspection program (e.g., IMC 2500 series IPs associated with operating or decommissioning reactor facilities).

Issue Date: 10/16/24 18 2690 Table A-4 IP SUBJECT INITIAL NLT FREQUENCY 60858 Away from Reactor ISFSI Inspection Guidance Initial operation of an AFR ISFSI1 Triennial 60857 Review of 10 CFR 72.48 evaluations As needed to support above IP As needed to support IPs 60859 Independent Spent Fuel Storage Installation (ISFSI) License Renewal Inspection Once when a licensee enters the period of extended operation at the first available opportunity not to exceed the end of the next triennial inspection period.

For specific licensees co-located with power reactors, initial operation begins with the termination of the Part 50 reactor license associated with the ISFSI.

Inspections previously performed at the facility under IP 60855 and IP 81311 can be credited as the initial Phase 4 inspection.

2690A-03 CONDUCT OF SUPPLEMENTAL OR REACTIVE INSPECTIONS The frequencies discussed in this Appendix and their associated level of effort defined within the inspection procedure represent the minimum amount of oversight. Division management may increase the inspection frequency and/or level of effort of the inspections based on licensees performance. A significant increase in the level of effort, defined as more than 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br />, or an increase in inspection frequency should be discussed and coordinated with DFM. Examples of licensee performance where more inspection may be performed include repetitive violations, or a Severity Level I, II, or III violation from the most recent inspection. Additional inspection effort should be targeted within the five safety focus areas most affected by the above examples to aid the NRC in their determination for the reasons of degraded performance.

Division management may also increase the inspection frequency and/or inspection hours of the inspections if an event occurs that warrants a reactive inspection. Events should be evaluated for significance to determine if any additional inspection effort is warranted and if so, whether an in-office review or in-field review is appropriate. Management Directive 8.3 NRC Incident Investigation Program and IMC 0309, Reactive Inspection Decision Basis for Reactors may be used to document the decision and approval for conducting a reactive inspection.

Issue Date: 10/16/24 19 2690 Additionally, the decision and the basis of the decision to not pursue a reactive inspection should also be documented. Reactive inspections of abnormal situations and events may use the IPs in this Appendix, as applicable. However, this inspection guidance may be supplemented by other IPs from the IMC 2515 and IMC 2561 inspection programs, as appropriate.

The DFM/PM and the Regional Branch Chief should coordinate with the cognizant NRR/PM, as necessary, regarding any planned Special Inspection Team (SIT), Augmented Inspection Team (AIT), or Incident Investigation Team (IIT) inspections at ISFSIs located at Part 50 licensees.

During the conduct of inspection activities, if additional inspection effort is needed outside of the circumstances described above, the inspectors shall consult with the regional branch chief for approval.

2690A-04 INSPECTION PROGRAM COMPLETION Inspection program completion is defined as the completion of all inspection procedures in accordance with Section 2690A-02 or 2690B-02, including both initial and recurring frequency inspections. Licensee and vendor schedules are beyond the control of NRC staff. Therefore, an unforeseen delay in a licensee or vendor schedule that results in not meeting an inspection requirement does not reflect non-completion of the inspection program, however notification shall be provided to the DFM/Branch Chief IOB. In such cases, the inspection should be completed as soon as possible.

If there is a deviation in the inspection program, the responsible office shall notify the DFM/Branch Chief IOB, as soon as practical but no later than 30 days after the inspection procedure due date. The notification should include a narrative discussion explaining the circumstances of the deviation and documenting what if any additional actions were taken to continue to provide reasonable assurance of adequate protection

Issue Date: 10/16/24 20 2690 Appendix B: Inspection Program Guidance for Transportation Packagings 2690B-01 SCOPE This appendix provides guidance related to the inspection program for activities related to the design, modification, fabrication, assembly, testing, procurement, repair, and maintenance of transportation packagings.

Inspections are performed by DFM/IOB to establish that radioactive material transportation packaging activities are performed in accordance with commitments and requirements specified in the CoC, SAR, NRC-approved Quality Assurance Program for Transportation of Radioactive Materials, and 10 CFR Part 71, and to determine that the transportation packaging is safe to use based on observation of activities, and an examination of permanent quality records and other supporting documentation. The SAR describes design, fabrication, test, and maintenance commitments and functions for a given transportation packaging.

2690B-02 INSPECTION FREQUENCY Inspection guidance for transportation packagings is provided by IP 86001, Design, Fabrication, Testing, and Maintenance of Transportation Packagings. Additional inspection guidance is in NUREG/CR-6314, Quality Assurance Inspections for Shipping and Storage Containers and Regulatory Guide 7.10, Establishing Quality Assurance Programs for Packaging Used in the Transport of Radioactive Material.

After the initial transportation packaging fabrication inspection, inspections should be performed during future fabrication activities based on one or more of the following: 1) length of time between fabrication of the packagings, 2) CoC holder and fabricator performance, or 3) operating experience for packaging use.

Issue Date: 10/16/24 21 2690 These inspection requirements apply to each fabricator and/or fabrication facility and each new package design being fabricated.

2Note: This inspection milestone also applies to completion of the initial fabrication of a packaging at a new fabricator if the packaging has previously been fabricated elsewhere.

3Note: The inspection frequency may be extended to the end of the corresponding fiscal year.

4Note: If several packagings are being fabricated at one time, then the milestone should be completed before the fabricator finishes manufacturing the last of that series of packagings.

Issue Date: 10/16/24 22 2690 Appendix D: Guidance for Risk Informed Inspection Prioritization 2690D-01 SCOPE As described in IMC 2691, Technical Basis for the Independent Spent Fuel Storage Installation Inspection Program, five safety focus areas were established to monitor licensee performance to have reasonable assurance of adequate protection.

a. Occupational Exposure

b. Public Exposure

c. Fuel Management

d. Confinement/Canister Integrity

e. Impact to Plant Operation Available spent fuel risk analyses, nuclear byproduct material radiological safety significance factors described in IMC 2691, as well as subject matter expertise gained from dry cask storage inspections since the beginning of the program were evaluated to inform this guidance.

Standard inspection activities were evaluated and prioritized in accordance with their relative risk. Priority level 1 activities were determined to have the highest amount of risk, necessitating the greatest level of inspection effort while priority level 3 activities were determined to have the lowest amount of risk, necessitating the lowest level of inspection effort. The inspection resources section in each procedure dictates the overall level of effort estimated to be spent to complete the inspection procedure. Inspectors should use the guidance in the table below to prioritize activities for the applicable inspection procedure, however, site-specific conditions should be evaluated to determine if any reprioritization is necessary following branch chief approval.

The graded-approach tables rate storage system components from priority 1 to 3 based on potential impact on safety. Priority 1 items are components that are important to safety and changes that could increase risk. Priority 2 items are components and changes that could potentially cause a low increase in risk. Priority 3 items are components and changes that could have very low or no impact on risk.

Issue Date: 10/16/24 31 2690 Appendix F: Inspection Program Modifications During Pandemics, Epidemics, or Other Widespread Illnesses or Diseases 2690F-01 PURPOSE Pandemics, epidemics, or other widespread illnesses or diseases primarily affect people and develop more gradually, spread more widely, and could persist longer than other natural phenomena. During these times, the U.S. Nuclear Regulatory Commissions (NRCs)

Inspection implementing strategy should be agile and allow for flexibility in the completion of the ISFSI and transportation packaging inspection program at affected facilities. The inspection program provides reasonable assurance that licensees and Certificate of Compliance (CoC) holders are in compliance with their licenses, certificates, and the applicable regulations.

Licensees and CoC holders have the ultimate responsibility to safely operate their facilities and/or perform their authorized activities in accordance with their licenses and certificates.

During the time of a pandemic, epidemic, or other widespread illness or disease, the NRC will use a graded approach to meet the objectives of the oversight program. A graded approach allows for deferring/rescheduling planned inspections, changing the inspection periodicity, adjusting inspection levels (number of completed inspection activities), conducting inspections leveraging remote means, or a combination of these actions, while seeking to maintain as much of the normal inspection program as possible. This is based on the conditions being experienced and information and guidance from Federal, State, and local government agencies, keeping in full view the health and safety of the personnel involved.

On June 1, 2020, the Office of Nuclear Materials Safety and Safeguards (NMSS) issued a memorandum entitled Inspection Guidance During Transition from COVID-19 Mandatory Telework for the Nuclear Materials and Waste Safety Programs (Accession No. ML20143A2810). This appendix formalizes the guidance provided by the memorandum and provides specific guidance as it relates to inspection programs for independent spent fuel storage installations (ISFSIs), dry storage systems (DSSs), and transportation packagings.

2690F-02 OBJECTIVES To provide direction for modifying the ISFSI and transportation packaging inspection program in the event of a pandemic, epidemic, or other widespread illness or disease.

2690F-03 APPLICABILITY IMC 2690, Inspection Program for Storage of Spent Reactor Fuel and Reactor-Related Greater-Than-Class C Waste at Independent Spent Fuel Storage Installations and for 10 CFR Part 71 Transportation Packagings.

NMSS or the regional offices may supplement, alter, or suspend the provisions of this guidance by memorandum as the situation warrants. The Director of the Division of Fuel Management (DFM) (and the Branch Chief of the Inspections and Oversight Branch (IOB)) should be consulted when conditions requiring additional guidance are warranted.

Issue Date: 10/16/24 32 2690 2690F-04 DEFINITIONS Headquarters Based Inspections: Inspection performed by inspectors in the DFM, including Inspection Procedure (IP) 60851, IP 60852, IP 60853, and IP 60857.

Region Based Inspections: Inspection performed by regional inspectors, including IP 60853, IP 60854, IP 60855, IP 60856, IP 60857, and IP 60858.

2690F-05 RESPONSIBILITIES AND AUTHORITIES See IMC 2690 2690F-06 REQUIREMENTS See IMC 2690 2690F-07 GUIDANCE In the event of a pandemic, epidemic, or other widespread illness or disease, the following considerations are in effect:

a. The regions and headquarters are expected to make a reasonable effort to complete the inspection program. However, the Regional Administrator or Director of DFM, with concurrence from the Director of NMSS can suspend implementation of the inspection program should conditions warrant. If this should occur, the primary function of inspectors and the implementing office would be to maintain situational awareness and the ability to respond to emergency situations.

b. Regions should continue to adequately evaluate and respond to events at a facility during a pandemic, epidemic, or other widespread illness or disease. If onsite response by NRC personnel is not possible, then the regions should collect information on the event remotely.

c. Inspectors should coordinate oversight activities of independent spent fuel storage installations (ISFSIs) at operating reactors as needed with resident inspector staff.

Regional inspectors shall follow guidance provided in IMC 2515 Appendix E, Inspection Program Modifications During Pandemics, Epidemics, or Other Widespread Illnesses or Diseases. Regional inspectors should support the resident inspectors as needed to ensure the safety of ISFSIs at operating reactors.

d. For ISFSIs without a resident inspector, at the onset (declaration) of the pandemic, epidemic, or other widespread illness or disease and periodically thereafter, the inspectors should verify that the licensees have sufficient staffing levels in key positions (e.g., operations, emergency response organization, security) to ensure that the facilities are operated safely and that licensee activities do not pose an undue risk to public health and safety. Additionally, the inspectors should evaluate deferred maintenance and other activities, use of overtime, and the need for licensing or other regional support.

The licensees operational status may be an additional consideration when determining modifications to the inspection program and any necessary site coverage.

Issue Date: 10/16/24 33 2690

e. For ISFSIs without a resident inspector and for CoC holders, the inspectors should discuss with their licensees and CoC holders the need to maintain situational awareness of the licensees or CoC holders ability to cope with the challenges associated with a pandemic. They should use Regulatory Issue Summary 2010-04, Monitoring the Status of Regulated Activities during a Pandemic, dated May 25, 2010, and other appropriate guidance as a resource.

The regulatory issue summary includes several questions that inspectors should consider during routine business contacts with licensees and CoC holders. The information obtained will enable the NRC to effectively respond to licensees and CoC holders with potential challenges. Inspectors should recognize that during a pandemic, epidemic, other widespread illness or disease, licensees and CoC holders resources may be strained. Therefore, inspectors should work with licensees and CoC holders to obtain the best information possible given the circumstances.

f.

Inspectors should be cautious when accessing licensee and CoC holder facilities during a pandemic, epidemic, or other widespread illness or disease using conservative good judgment so as not to unnecessarily risk the health of licensee and CoC holder employees. A graded approach based on the current licensee, or CoC holder response posture should be considered for determining inspector site access.

To minimize the spread of infections, NRC staff members at or visiting sites should strive to follow any licensee or CoC holder plans in place. Additionally, inspectors should follow any applicable Federal, State, or local health screening guidance in effect to determine if it is appropriate to enter a site and interact with licensee or CoC holder personnel.

If licensees or CoC holders are conducting health screenings to permit site access, inspectors should generally comply with those requests similar to their adherence to Occupational Safety and Health Administration or other industrial safety requirements.

Inspectors should contact their management if the licensee or CoC holder implements changes to normal access to the site and coordinate with management if unfettered site access in accordance with10 CFR 72.82(c)(3) and 10 CFR 50.70(b)(3) is denied or restricted.

g. During the pandemic, epidemic, or other widespread illness or disease, the regions and headquarters should consider modifications to the inspections as follows:

1. Local implementation of limited social distancing (e.g., canceling after-school activities, limiting public gatherings, or advising nonessential workers to remain home)

(a) Region-based inspections: Assess the potential to postpone or reschedule onsite inspections.

Evaluate whether IP 60855 and IP 60858 frequency-based inspection activities may be postponed and still meet IMC 2690 requirements.

Evaluate whether IP 60853, IP 60854, and IP 60856 inspection may be performed remotely.

Issue Date: 10/16/24 34 2690 Assess the potential to perform inspection activities through remote/virtual means.

Identify opportunities to leverage technology to inspect remotely. Potential candidates include, but are not limited to, ISFSI monitoring inspections, review of Title 10 of the Code of Federal Regulations (10 CFR) 72.212 evaluations, review of 10 CFR 72.48 evaluations, etc.

(b) Headquarters-based inspections: Assess the potential to postpone or reschedule onsite inspections.

Evaluate whether IP 60851, IP 60852, and IP60853 frequency based inspection activities may be postponed and still meet IMC 2690 requirements.

Evaluate whether IP 60851 and IP 60852 initial inspection activities may be postponed and still meet IMC 2690 requirements.

Assess the potential to perform inspection activities through remote/virtual means.

Identify opportunities to leverage technology to inspect remotely. Potential candidates include, but are not limited to, review of the programmatic aspects of quality assurance program (QAP) implementation including associated documentation and evaluations if not the initial inspection, review of 10 CFR 72.212 evaluations to support regional inspections, review of 10 CFR 72.48 evaluations, etc.

2. Local or national state of emergency or widespread implementation of aggressive social distancing (e.g., closure of schools, public parks, and nonessential businesses; requiring nonessential workers to remain home)

(a) Region-based inspections: Consider deferring/postponing all onsite inspection activities.

Assess inspection procedure objectives and licensee personnel support to determine whether procedures can be performed remotely.

(b) Headquarters-based inspections: Consider deferring/postponing all onsite inspection activities.

Assess inspection procedure objectives and licensee and CoC holder personnel support to determine whether procedures can be performed remotely.

3. Implementation of the NRC Continuity of Operations Plan (a) Implement site coverage, facility status monitoring, and emergency response in accordance with the NRC Continuity of Operations Plan.

h. Open communications and coordination between DFM and Regional Offices is important during a declared pandemic, epidemic, or other widespread illness or disease.

Alignment should be reached on a case-by-case basis on the capability to perform

Issue Date: 10/16/24 35 2690 remote inspections to fulfill IMC 2690 requirements, need to perform onsite inspections, and deferral of inspections.

1. The DFM/Branch Chief IOB should coordinate communications with the responsible regional branch chief for oversight activities to ensure a consistent approach to inspections.

2. The responsible branch chief should document the adequacy of methods for performing remote inspections on a case-by-case basis in a memorandum to file.

These methods should be discussed between the DFM/Branch Chief IOB and the responsible regional branch chief, as applicable, to ensure they meet the applicable inspection procedure requirements.

3. Onsite inspections should be discussed between the DFM/Branch Chief IOB and the responsible regional branch chief, as applicable, to ensure the applicable inspection procedure requirements, licensee performance, available remote inspection methods, and site conditions warrant an onsite inspection presence.

(a) Onsite inspections should be communicated by the Regional Administrator or Director, DFM for region or headquarters-based inspections accordingly to the Office of the Executive Director for Operations.

4. Planned deviations in the inspection frequency from the requirements of IMC 2690 due to an inspection deferral should be communicated quarterly in a memorandum to the DFM/Branch Chief IOB.

5. An inspection deferral that will still be completed within the frequency from the requirements of IMC 2690 does not require coordination with the DFM/Branch Chief IOB if the inspection requirements can still be met once deferred.

i.

The NRC should consider the threshold at which onsite response is needed for an event.

For example, the NRC may be able to perform some level of remote monitoring depending on the accessibility of the licensee's network. If direct onsite response is appropriate, the regions could consider limiting the response, such as having a single inspector respond to the emergency response facility or technical support center only.

j.

The NRC should reduce, as appropriate, management site visits required in accordance IMC 0102, Oversight and Objectivity of Inspectors and Examiners at Reactor Facilities.
