CONNECTICUT YANKEE ATOMIC POWER COMPANY HADDAM NECK PLANT PLANT 362 INJUN HOLLOW ROAD s EAST HAMPTON, CT 06424-3099 August 3, 2022 CY-22-012 Re: 10 CFR 72.4 and 10 CFR 72.30 ATTN: Document Control Desk, U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Connecticut Yankee Atomic Power Company Haddam Neck Plant Independent Spent Fuel Storage Installation NRC License No. DPR-61 {NRC Docket No. 50-213)
Subject:
Supplemental Information for the Three-Year Update to the Independent Spent Fuel Storage Installation Decommissioning Funding Plan On December 10, 2021, pursuant to the requirements of 10 CFR 72.30(c) and 10 CFR 72.4, Connecticut Yankee Atomic Power Company (CYAPCO) provided the three-year update to the Independent Spent Fuel Storage Installation (ISFSI) Decommissioning Funding Plan (DFP)
(Reference 1). It included a modified assumption that significantly reduced the amount of material that would be shipped offsite as low-level radioactive waste. This letter provides supplemental infonnation to define the basis for the modified assumption.
CYAPCO utilized TLG Services, LLC as the independent contractor to perform the Decommissioning Cost Estimates (DCEs) provided on December 10, 2018 and December 10, 2021 (References 2 and 1, respectively). Attachment 1 provides TLG Services, LLC's bases for the reduction in the volume of radioactive waste from that assumed in the previous DCE.
In addition, the volume of low-level radioactive waste that is assumed to require remediation and shipment to an offsite facility is consistent with other licensees' DCEs that the NRC has previously reviewed. In References 3 and 4, South Carolina Electric & Gas and Santee Cooper submitted their initial decommissioning cost estimates for the Virgil C. Summer Nuclear Station Unit 1 ISFSI. These documents state:
"The dry storage vendor, Holtec International, does not expect the overpacks to have any interior or exterior radioactive surface contamination. Any neutron activation of the steel and concrete is expected to be extremely small. The decommissioning estimate is based on the premise that some of the inner steel liners and concrete overpacks will contain low levels of neutron-induced residual radioactivity that would necessitate remediation at the time of decornmissioning. As an allowance, 5 of the 75 Holtec overpacks are assumed to be affected, i.e., contain residual radioactivity. The allowance quantity is based upon the number of casks required for the final core off-load (i.e., 157 off-loaded assemblies, 37 assemblies per cask which results in 5 overpacks). It is assumed that these are the final casks offloaded;

Connecticut Yankee Atomic Power Company CY-22-012/August 3, 2022/Page 2 consequently they have the least time for radioactive decay of the neutron activation products."
In Reference 5, the NRC provided their analysis of the decommissioning cost estimates for the Virgil C. Summer Nuclear Station Unit 1 ISFSI. The NRC states:
"Based on its financial analysis of SCE&G' s and Authority's submittals, the NRC staff finds that the DCEs submitted for 2016: ( 1) are based on reasonable costs of a third patty contractor; (2) include an adequate contingency factor; (3) reflect the cost of meeting the 10 CFR 20.1402 criteria for unrestricted use; and (4) are based on reasonable and documented assumptions. Therefore, the NRC finds that the 2016 DCEs adequately estimate the cost, to cany out required ISFSI decommissioning activities prior to license tennination, and that the 2016 DCEs are acceptable."
In conclusion, the TLG Services, LLC bases provided in Attachment 1 and the precedent identified above justify the reduction in the volume of material that is assumed to be required to be remediated and shipped offsite in the DCE provided in December 2021 (Reference 1).
If you have any questions regarding this submittal, please do not hesitate to contact me at (508) 612-3322.
Respectfully,

ATTACHMENT 1 TO CY-22-012 TLG Services, LLC Bases for Low-Level Radioactive Waste Volume Assumption in December 2021 Decommissioning Cost Estimate Prior to 2021, the Connecticut Yankee Atomic Power Company (CYAPCO) ISFSI decommissioning cost estimate was based on the general assumption that all of the overpacks and storage pads would be contaminated and require disposal as low-level waste. For the 2021 estimate, it was discussed that this assumption was overly conservative. CYAPCO engaged TLG to change this assumption to the standard that TLG assumes for the maj01ity of their clients.
Specifically, the number of storage canisters is based upon the number of canisters required for the final core off-load. It is assumed that these are the final casks offloaded; consequently, they have the least time for radioactive decay of the neutron activation products. The remaining overpacks and storage pad are assumed to be surveyed and free released.
While there is no generic guideline available for the quantity of activated material present in different designs for Dry Cask Storage Systems, the Final Safety Analysis Report (FSAR) for several storage systems references activation as a characteristic that must be assessed during decommissioning; however, the amount of neutron activation is expected to be small. For reference several documents are listed below:
Holtec Hi-Storm FSAR 3/31/16 ADAMS Accession Number: ML16138A100 Section 2.4, Decommissioning Considerations. This document states that the overpack would have no interior or exterior surface contamination and that any neutron activation is expected to be extremely small. It is also stated that the overpack could be decontaminated to allow recycle or reuse options. In addition, no residual contamination is expected to be found on the storage pad.
NUHOLMS HD Horizontal Modular Storage System for lirndiated Nuclear Fuel, Safety Analysis Report, Rev. 0, April, 2004 ADAMS Accession Number: ML041540170 Section 2.4 Decommissioning Considerations. This document states that because of minimal contamination of the outer surface of the Dry Shielded Canister (DSC), no contamination is expected inside the Horizontal Storage Module (HSM). It is further stated that the HSMs can be dismantled and disposed of using commercial techniques.
NAC-MPC Final Safety Analysis Report, Revision 12, April 2019 ADAMS Accession Number: ML19113A211 Section 2.4 Decommissioning Considerations. This document states that activation of the carbon steel liner, concrete, support plates, and reinforcing bar could occur due to neutron flux from the stored fuel. Since the neutron flux rate is low, only minimal activation of carbon steel in the Page 1 of 3
ATTACHMENT 1 TO CY-22-012 TLG Services, LLC Bases for Low-Level Radioactive Waste Volume Assumption in December 2021 Decommissioning Cost Estimate concrete cask is expected to occur. It is expected that the concrete will be broken up, and steel components segmented, to reduce volume. Any contaminated or activated items are expected to qualify for near-surface disposal as low specific activity material. In addition, the storage pad, fence, and supporting utility fixtures are not expected to require decontamination as a result of use of the Universal Storage System.
NUREG-2215. Standard Review Plan for Spent Fuel D1y Cask Storage Systems and Facilities, April 2020 ADAMS Accession Number: ML20121A190 Section 14 Decommissioning Evaluation. This document describes the NRC's objective to ensure that the applicant's provisions for eventual decontamination and decommissioning of the ISFSI provide reasonable assurance that:
(1) the proposed provisions for eventual decontamination and decommissioning of the ISFSI will provide adequate protection of public health and safety (2) funds will be available to decommission the ISFSI (3) the design and operational features of the ISFSI facilitate eventual decontamination and decommissioning.
IAEA Technical Document -1081 Spent fuel storage and transport cask decontamination and modification. April 1999 URL: https://www-pub.iaea.org/MTCD/publications/PDF/te_ I 081 __pm.pdf Section 2.3 Neutron Activation of Cask Strncture: While this publication states that in 8 to 10 years after fuel removal, the activated casks and concrete should decay to acceptable levels, currently there is no Below Regulat01y Concern (BRC) for US licensees.
Discussion and Conclusions A MARS SIM-type survey on the over-pack steel and concrete using the most sensitive and appropriate detection instrnment available (per MARSSIM) would determine if the subject containers are free releasable. Note that with evolving technologies it is expected that the level of detection for key radionuclides will improve over time.
In terms of the TLG "Class A" thumb rule: Using the volume of the cask systems for the last full core off-load is reasonable as these are likely to have the highest neutron flux/residual activation products with the least amount of decay time. Ultimately, a MARS SIM-type survey and characterization should be petfonned on the remaining site components post-DOE pickup to determine if contamination/activation products are present. In the case of a SAFSTOR scenario where the DOE removes the stored spent fuel IO+ years prior to site demolition (assumes that Page 2 of 3

Making the above-described change to the CYAPCO Haddam Neck Plant ISFSI decommissioning cost estimates results in a significant reduction in waste volume and disposal costs. TLG believes this change is reasonable and is consistent with the DCEs developed by TLG for other utilities.
