SUMMARY
Energy Harbor Nuclear Corp.
Beaver Valley Power Station (BVPS)
NRC Inspection Report Nos: 07201043/2020001 and 2020002 On October 22, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed a period of onsite and remote inspections of Beaver Valleys Independent Spent Fuel Storage Installation (ISFSI) activities. Onsite inspections were performed on June 16-18, 2020 at TNs training facility in Aiken, South Carolina to inspect BVPSs pre-operational ISFSI testing. On October 19-22, 2020, inspectors inspected the dry cask storage loading campaign (first of four Dry Storage Casks, DSCs) at the Beaver Valley Power Station (BVPS). Additional inspection activities (in office reviews via remote means) were conducted throughout the period as a consequence of the COVID-19 public health emergency (PHE). The inspectors examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations, and the conditions of your license and the Certificate of Compliance (COC). The inspection consisted of observations by the inspectors, interviews with site personnel, and a review of procedures and records. 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 Dry Storage of Spent Reactor Fuel at Independent Spent Fuel Storage Installations and For 10 CFR Part 71 Transportation Packagings.
No findings or violations were identified during this inspection.
1 1.0 Independent Spent Fuel Storage Installation (ISFSI)
1.1 Background
Owner/Operator Energy Harbor - Beaver Valley Power Station (BVPS), selected ORANO/TN Americas LLC (TN) NUHOMS EOS System technology to allow spent nuclear fuel assemblies currently stored in the BVPS Unit 1, Spent Fuel Pool (SFP) to be relocated and stored using an ISFSI. The TN NUHOMS EOS System is listed in 10 CFR 72.214, List of Approved Spent Fuel Storage Casks, under Certificate of Compliance (CoC) 1042, with an effective date of June 7, 2017 and a 20-year term. TN Updated Final Safety Analysis Report (UFSAR), Revision 3 applies to the four (4) NUHOMS EOS Systems that will be placed in service under CoC 1042, Amendment 1, at BVPSs ISFSI.
Amendment 1 of CoC 1042 became effective on June 17. 2020.
1.2 Pre-Operational Testing of ISFSI at Operating Plants at Operating Plants (IP 60854)
- a.
Inspection Scope On June 16-18, 2020, the U.S. Nuclear Regulatory Commission (NRC) initiated its inspection of Beaver Valley Power Stations (BVPS) ISFSI pre-operational demonstration.
Inspectors traveled to TN's training facility in Aiken, South Carolina to observe and evaluate BVPSs pre-operational testing and training exercise. These operations were evaluated using the TN NUHOMS EOS Certificate of Compliance No. 72-1042, Amendment 1, Condition 9. On October 14-15, 2020, the inspectors continued the preoperational inspection by reviewing, (via remote means), BVPS demonstrating their facility in moving and removing spent fuel into and out of the NUHOMS EOS cask, as well as down-ending the cask for transport.
Observations and Findings - Dry Run Activities During the inspection period, inspectors specifically observed the following demonstrations that were successfully completed by the licensee: DSC sealing, drying and backfilling operations including welding of the canister top cover plates, welding of the vent and drain ports, Nondestructive examinations (NDE) of the welds (e.g., visual, liquid penetrant, and helium leak), vacuum drying, pneumatic testing, helium backfill, cutting of the lid from the DSC shell, cutting of the vent/drain port openings, and flooding the DSC.
The inspectors reviewed various documents to support the demonstrations listed above, including welder and NDE personnel qualification programs, weld, helium leak test and NDE procedures. Additionally, the vacuum drying, backfill, pneumatic testing, weld cutting, and re-flood procedures were reviewed and evaluated.
- b.
Findings No findings of safety significance were identified.
2 1.3 Operation of an ISFSI at Operating Plants (IP 60855 and 60855.1)
- a.
Inspection Scope On October 19-22, 2020, the inspectors observed and evaluated BVPSs loading of DSC Serial No. BV-3-DSC-11 (first of four DSCs to be loaded during dry cask campaign),
Model No. EOS-37PTH, related to long-term operation and monitoring of the ISFSI. The inspectors verified compliance with TN NUHOMS EOS CoC No. 72-1042, Amendment 1, TNs UFSAR for the NUHOMS EOS Horizontal Storage Modular System for Irradiated Nuclear Fuel, Revision 3, CoC Appendix A, EOS System Generic Technical Specifications (TS), U.S. Nuclear Regulatory Commission (NRC) Final Safety Evaluation Report (SER), Title 10 of the Code of Federal Regulations (CFR) Part 72 requirements, and BVPS procedures.
The NUHOMS EOS System consists of a Dry Shielded Canister (DSC) stored in a Horizontal Storage Module (HSM). A Transfer Cask (TC) was used to handle the DSC during fuel loading, preparation for storage in the BVPS Unit 1 Fuel Building and the Decontamination Building and to facilitate transfer of the DSC into the HSM at the ISFSI.
The following specific hardware models were used at the BVPS ISFSI under NUHOMS EOS CoC 1042:
EOS-37PTH DSC, Basket Type B4H/B4L, Basket Length 187.15 inches EOS-HSM, FPS Medium EOS-TC125 Observations and Findings - Loading Operations The inspection was timed such that risk-significant activities were observed. Specifically, the inspectors observed and evaluated the critical tasks associated with the licensees spent fuel loading, processing, and down ending operations. The inspectors observed: a) heavy load movement of the transfer cask (TC), used for transfer operations within the spent fuel pool area and for transfer operations to/from the HSM and the loaded DSC from the spent fuel pool to the cask processing area; and b) numerous activities associated with DSC loading operations including installation of the DSC inner top cover, removal of the annulus seal, installation of the automated welding system, remote welding, NDE weld examinations, draining, vacuum drying, helium backfill, surveying, and decontamination. During performance of these activities, the inspectors verified that procedure use, communication, and coordination of ISFSI activities met BVPSs approved procedures and regulatory requirements.
The inspectors reviewed BVPSs program associated with fuel characterization and selection for storage. The inspectors reviewed BVPSs calculation package that depicted fuel selection for the 2020 BVPS Unit 1 dry cask storage campaign. In addition to the records review, the inspectors reviewed a video of each fuel rod loaded into DSC 11 for traceability and for compliance to BVPSs loading plan. Overall, a DSC 11 loading map was developed and implemented. Overall, fuel assemblies were verified to meet the requirements of the TSs of CoC 1042. With respect to DSC 11, the minimum boron concentration necessary for loading and the decay heat was 2300 ppm and 22.79 kW, respectively.
The inspectors observed radiation protection technicians as they provided job coverage for the cask loading workers. The inspectors reviewed survey data maps and radiological records from the DSC loading to confirm that radiation survey levels measured were within limits specified by the TS and consistent with values specified in the UFSAR. The
3 results of ISFSI pad Thermoluminecent Dosimeter (TLDs) and surveys were also reviewed.
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 HSMs. The inspectors also verified that transient combustibles were not being stored on the haul path, ISFSI pad or in the vicinity of the HSMs. The inspectors also confirmed that transient combustible material entry onto the ISFSI pad was controlled in accordance with approved procedures.
The inspectors reviewed corrective action reports and the associated follow-up actions that were generated since BVPSs last loading campaign to ensure appropriate implementation of BVPSs corrective action program commensurate with their safety significance. In addition, the inspectors noted BVPSs assessment of industry operational experiences at a licensees facility that recently deployed the same EOS dry cask system.
The inspectors concluded that BVPS continues to implement successful programs related to training, procedures, equipment maintenance, and oversight to ensure safe and compliant downloading operations. The inspectors observed that the status of the canisters during downloading operations were constantly monitored and properly handled to avoid possible loading issues.
- b.
Findings No findings of safety significance were identified.
1.4 Exit Meeting On November 4, 2020, the inspectors presented the inspection results to Mr. R. Penfield, Site Vice President, and other members of Energy Harbors staff who acknowledged the inspection results. No proprietary information was retained by the inspectors or documented in this report.
