SUBJECT:
LIMERICK GENERATING STATION - INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI) NRC INSPECTION REPORT NO.
07200065/2021001 AND EXERCISE OF ENFORCEMENT DISCRETION
Dear Mr. Rhoades:
On February 8, 2022, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection of the Limerick Generating Station (Limerick) Independent Spent Fuel Storage Installation (ISFSI) activities. On-site inspections were performed on August 16 - 20, 2021, September 9 - 15, 2021, September 21, 2021, and September 26 - October 2, 2021.
Additional inspection activities (in office reviews via remote means) were conducted throughout the period as a consequence of the COVID-19 public health emergency. The inspectors examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations, the conditions of your license and the Certificate of Compliance (CoC). The inspection consisted of observations by the inspectors, interviews with site personnel, a review of procedures and records, and plant walkdowns. The results of this inspection were discussed with Mr. Frank Sturniolo, Site Vice President, and other members of your staff on May 31, 2022, and are documented in the enclosed report.
The inspectors identified a violation of 10 CFR 72.48 associated with tornado hazard protection. Because this violation was identified during the discretion period covered by Enforcement Guidance Memorandum 22-001, Enforcement Discretion for Noncompliance of Tornado Hazard Protection requirements at Independent Spent Fuel Storage Installations, and because Constellation was implementing compensatory measures and has taken or plans to take the necessary actions to restore compliance, the NRC is exercising discretion by not issuing an enforcement action for the violation and is allowing continued ISFSI handling operations.

EXECUTIVE SUMMARY
Constellation Energy Generation, LLC
Limerick Generating Station NRC Inspection Report No. 07200065/2021001
On February 8, 2022, the U.S. Nuclear Regulatory Commission (NRC) competed an inspection of the Independent Spent Fuel Storage Installation (ISFSI) activities at Limerick Generating Station. On-site inspections were performed for the 10 CFR 72.212(b) evaluation on August 16
- 20, 2021. On-site inspections were performed for dry run operations for transportation on September 9 - 15, 2021, and for spent fuel pool operations on September 21, 2021. An on-site inspection of the initial Holtec dry cask loading at Limerick was performed on September 26 -
October 2, 2021. Additional inspection activities (in office reviews via remote means) were performed throughout this period as a consequence of the COVID-19 public health emergency, including the completion of the initial Holtec two cask loading campaign. The inspection consisted of observations by the inspectors, interviews with site personnel, a review of procedures and records, and plant walk-downs. The NRCs program for overseeing the safe operation of dry storage of spent fuel at an ISFSI is described in Inspection Manual Chapter 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.
The inspectors identified a violation of 10 CFR 72.48 associated with tornado hazard protection. Because this violation was identified during the discretion period covered by Enforcement Guidance Memorandum 22-001, Enforcement Discretion for Noncompliance of Tornado Hazard Protection requirements at Independent Spent Fuel Storage Installations, and because the licensee was implementing compensatory measures and has taken or plans to take the necessary actions to restore compliance, the NRC is exercising discretion by not issuing an enforcement action for the violation and is allowing continued ISFSI handling operations.
REPORT DETAILS
1.0 Independent Spent Fuel Storage Installation
1.1 Background
Owner/Operator Constellation - Limerick Generating Station (Limerick), selected Holtec HI-STORM FW Cask System technology to allow spent nuclear fuel assemblies currently stored at Limericks spent fuel pool (SFP) to be relocated and stored using an ISFSI. The Holtec system is listed in 10 CFR 72.214, List of Approved Spent Fuel Storage Casks, under Certificate of Compliance (CoC) No. 1032. Holtec Final Safety Analysis Report (FSAR), Revision 4 applies to the Holtec ISFSI system that was placed in service under CoC number 1032.
1.2 Onsite Fabrication of Components and Construction of an ISFSI (IP 60853)
a. Inspection Scope
The ISFSI pads located at Limerick are composed of three independent pads. The Limerick ISFSI pad was designed to accommodate TN NUHOMS Horizontal Storage Modules (HSM). At the time of this inspection, 55 casks were stored in NUHOMS HSMs and placed on the Limerick ISFSI pads. Constellation plans to load up to 36 HI-STORM FW units alongside the existing HSMs. The inspectors reviewed the evaluations to ensure a demonstration of reasonable assurance that the ISFSI pad at Limerick complies with the requirements of 10 CFR 72.212(b)(5)(ii). The inspectors performed a review of the structural assessment of the ISFSI pad design review for static and dynamic loads associated with the new casks, as required by 10 CFR 72.212. In addition, the inspectors reviewed the site-specific tip over analysis of the HI-STORM FW storage cask and the soil structure interaction analysis performed for Limerick. The inspectors focused their review on completeness and accuracy of the information provided by Constellation and verified that the analysis and design methodology used for the additional HI-STORM casks on the Limerick ISFSI pad was consistent with the HI-STORM FW FSAR as well as applicable guidance in American Concrete Institute (ACI) 318-05, ACI 349-06, NUREG-1536 and NUREG-0800. The staff concluded that Constellations overall approach was reasonable, satisfied the requirements of 10 CFR 72.212(b)(5)(ii), and therefore provides a reasonable assurance of safety.
b. Findings
No violations of significance were identified.
1.3 Pre-operational Testing of an ISFSI (IP 60854)
a. Inspection Scope
The inspectors evaluated Constellations performance during NRC observed pre-operational dry run activities that were performed in order to fulfill requirements in the NRC-issued CoC No. 1032, Amendment 1, Revision 1 (CoC 1032-1R1). The inspectors observed Constellations dry run activities related to transportation operations and spent fuel pool operations at Limerick on September 9 - 15, 2021 and September 21, 2021, respectively.
During the dry run activities, the inspectors observed cask loading and cask movement activities to determine whether Constellation had developed the capability to properly load and move the multi-purpose canister (MPC) to be used in storage of spent fuel at Limerick. The inspectors observed:
- (a) movement of a dummy fuel assembly into the MPC,
- (b) movement of the MPC/HI-TRAC from the fuel pool to the cask processing area
- (c) stack-up and transfer of the MPC from the HI-TRAC to the HI-STORM
- (e) retrieval of the MPC from the HI-STORM back into the HI-TRAC,
- (f) installation of the HI-STORM lid,
- (g) lifting of the HI-STORM off the HI-PORT using the hydraulic lifting gantry (HLG),and
- (h) placement of the HI-STORM on the ISFSI pad using the Air Caster and Jacking system.
The inspectors attended select Constellation pre-job briefings to assess Constellations ability to identify critical steps of the evolution, potential failure scenarios, and human performance tools to prevent errors. The inspectors reviewed the training program and training records of personnel assigned to ISFSI activities. The inspectors reviewed MPC loading, unloading, and processing procedures to determine if they contained commitments and requirements specified in the CoC, technical specifications (TSs),
FSAR, and Title 10 of the CFR Part 72. The inspectors also reviewed Constellations fuel selection procedures to ensure they appropriately incorporated the requirements in the TSs.
The inspectors reviewed radiation protection procedures and radiation work permits associated with the proposed ISFSI loading campaign. The inspectors also reviewed the radiological controls which would be established during an MPC loading campaign and reviewed corrective action reports associated with preparations for the ISFSI loading campaign to ensure that issues were being properly identified, prioritized, and evaluated commensurate with their safety significance.
b. Findings
No violations of significance were identified.
1.4 Operation of an ISFSI at Operating Plants (IP 60855)
a. Inspection Scope
From September 26 - October 2, 2021, the inspectors observed and evaluated Constellations loading of the first MPC associated with its initial Holtec HI-STORM FW Cask System dry cask campaign on-site at Limerick. The inspectors also reviewed the licensees planned activities associated with long-term operation and monitoring of the ISFSI. The inspectors evaluated compliance with the CoC, TSs, and station procedures.
The inspectors observed fuel assemblies being loaded into the MPC. The inspectors also observed MPC processing operations including welding, non-destructive weld examinations, hydrostatic testing, vacuum drying, helium backfill, and survey activities.
The inspectors observed movement activities including stack-up, HLG operation, and placement of HI-STORM onto the Air Caster system. During performance of these activities, the inspectors verified that procedure use, communication, and coordination of ISFSI activities met established Constellation standards and requirements.
The inspectors reviewed Limericks program associated with fuel characterization and selection for storage and reviewed the first cask fuel selection package to determine if the licensee was loading fuel in accordance with the CoC, TSs, and procedures.
Inspectors reviewed a recording made of the fuel assemblies loaded into the first MPC to ensure the loading was in accordance with Limericks loading plan.
The inspectors observed radiation protection surveys and job coverage for the cask loading workers, and reviewed survey data maps and radiological records from the first MPC loading to determine if radiation survey levels measured were within limits specified by the TSs and consistent with values specified in the FSAR.
The inspectors reviewed corrective action reports and the associated follow-up actions that were generated since Limericks dry run demonstrations, to ensure that issues were entered into the corrective action program (CAP), prioritized, and evaluated commensurate with their safety significance.
b. Findings
No violations of significance were identified.
1.5 Review of 10 CFR 72.212
- (b) Evaluations (IP 60856)
a. Inspection Scope
Limerick is utilizing the Holtec International HI-STORM FW Cask System for the storage of spent fuel at the onsite ISFSI. The HI-STORM FW casks augment the Standardized NUHOMS casks already in service at the current ISFSI, which began operation in 2008.
The review of the HI-STORM FW Cask System was based on NRC-issued CoC 1032-1R1 and its associated Safety Evaluation Report (SER), and HI-STORM FW FSAR Revision 4. The review of the Part 50 facility site-specific parameters utilized the Updated Final Safety Analysis Report (UFSAR) and other applicable plant-specific design and licensing basis information.
The inspectors evaluated the licensees compliance with the requirements of 10 CFR 72.212. The inspectors examined Constellations written evaluations to determine if they were in accordance with 10 CFR 72.212(b)(5) and evaluated the conditions set forth in the CoC to determine if conditions had been met prior to use and if the radiological requirements of 72.104 were met. The inspectors examined applicable reactor site parameters, such as hypothetical fire and explosions, tornadoes, wind-generated missile impacts, seismic qualifications, lightning, flooding and temperature, to determine if they had been evaluated for acceptability with bounding values specified in the FSAR and the NRC SER. The inspectors also examined 50.59 evaluations associated with the construction and operation of the ISFSI and plant interfaces to determine if they were performed and to determine if changes to certain facility design bases and UFSAR commitments required NRC approval. The reactor emergency plan, quality assurance program, training program, and radiation protection program were reviewed to determine if there was a decrease in effectiveness and if changes made required prior NRC approval.
b. Findings
Description
The inspectors identified a violation of 10 CFR 72.48 associated with tornado hazard protection. 10 CFR 72.48(c)(2)(ii) requires, in part, that a general licensee shall request that the certificate holder obtain a CoC amendment pursuant to 10 CFR 72.244, prior to implementing a proposed change, if the change would result in more than a minimal increase in the likelihood of occurrence of a malfunction of a system, structure, or component (SSC) important to safety (ITS) previously evaluated in the FSAR. This requirement includes the configuration where the HI-STORM FW overpack is lifted by the hydraulic lifting gantry (HLG) as part of ISFSI operations. The HLG is an ITS component used in cask handling operations and is not designed to be operated in wind speeds exceeding 35 mph. The introduction of the ITS HLG met the criterion that resulted in more than minimal increase in the likelihood of occurrence of a malfunction of an SSC ITS previously evaluated in the FSAR. The general design criteria require ITS structures used in ISFSI operations to be designed to withstand the effects of tornado missiles and winds.
Enforcement
Because this violation was identified during the discretion period covered by Enforcement Guidance Memorandum 22-001, Enforcement Discretion for Noncompliance of Tornado Hazard Protection requirements at Independent Spent Fuel Storage Installations, and because the licensee was implementing compensatory measures and has taken or plans to take the necessary actions to restore compliance, the NRC is exercising discretion by not issuing an enforcement action for the violation and is allowing continued ISFSI handling operations.
2.0 Exit Meeting
On May 31, 2022, the inspectors presented the inspection results to Mr. Frank Sturniolo, Site Vice President, and other members of the Constellation staff who acknowledged the inspection results. No proprietary information was retained by the inspectors or documented in this report.
