Subject:

Three-Year Update to the Independent Spent Fuel Storage Installation Decommissioning Funding Plan Pursuant to the requirements of 10 CFR 72.3 0(c) and 10 CFR 70.4, Maine Yankee Atomic Power Company (Maine Yankee) is providing the three-year update to the Independent Spent Fuel Storage Installation (ISFSI) Decommissioning Funding Plan (DFP). Enclosure 1 updates the Maine Yankee ISFSI decommissioning cost estimate and the cost estimate for the management of irradiated fuel and Greater than Class C Waste submitted with the original Maine Yankee ISFSI DFP on December 17, 2012 (Reference 1), as revised on January 8, 2013 (Reference 2). It includes adjustments to account for changes in costs. The update does not include any adjustments for additional radiological contamination, because the extent of radioactive contamination at the Maine Yankee ISFSI remains unchanged.

10 CFR 72.3 0(c) defines specific events that must be considered in the subsequent updates.Since the submittal of the original Decommissioning Funding Plan for the ISFSI in December 2012: 1. No spills of radioactive material producing additional residual radioactivity in onsite subsurface material have occurred.2. Facility modifications that affected the ISF SI, including those that were implemented within the licensed area, were assessed for impact.3. There were no changes in authorized possession limits.4. No active decommissioning has occurred, thus, there have not been any actual remediation costs that exceed the previous cost estimate.In addition, Maine Yankee complies with the requirements of 10 CFR 72.30(b)(1) through (b)(6), as follows.

Maine Yankee Atomic Power Company OMY-15-053/December 16, 2015/Page 2 10 CFR 72.30(b)(1) requires the licensee to provide "information on how reasonable assurance will be provided that funds will be available to decommission the ISFSI." Maine Yankee has established an account within its Nuclear Decommissioning Trust (NDT) entitled, "ISFSI Radiological Decom," that segregates the funds for decommissioning of the ISFSI from the larger balance of funds for ongoing management of irradiated fuel and GTCC waste held in the NDT. Currently, the trust has sufficient funds to meet the revised DCE for the Maine Yankee ISFSI.10 CER 72.30(b)(2) requires the licensee to provide a detailed cost estimate for decommissioning.

Enclosure 1 provides a revised DCE for the Maine Yankee ISFSI that: 1) Utilizes an independent contractor to perform the decommissioning activities in accordance with 10 CFR 72.30O(b)(2)(i);

2) Includes an adequate contingency factor in accordance with 10 CFR 72.30(b)(2)(ii);

and 3) Includes the cost of meeting the criteria for unrestricted release in accordance with 10 CFR 72.30(b)(2)(iii).

In addition, the revised Maine Yankee ISFSI DCE specifically considered the effects of the events described in 10 CFR 72.30(c) on the costs of decommissioning and the extent of contamination.

The revised Maine Yankee ISFSI DCE estimates the total cost to decommission the Maine Yankee ISFSI to be $27.4 million and $28.1 million (in 2015 and 2016 dollars, respectively), inclusive of radiological and non-radiological removal.10 CFR 72.30(b)(3) requires the licensee to identify and justify the key assumptions contained in the DCE. Enclosure 1 provides the revised DCE for the Maine Yankee ISFSI, including the key assumptions and the justification for their use.10 CFR 72.30(b)(4) requires the licensee to provide a description of the method of assuring funds for decommissioning from 10 CFR 72.30(e), including means for adjusting cost estimates and associated funding levels periodically over the life of the facility.

Maine Yankee will periodically reassess the decommissioning cost estimate in accordance with 10 CFR 72.30(c).On a periodic basis, Maine Yankee will submit rate cases to Federal Energy Regulatory Commission (FERC) that will include revised cost estimates for decommissioning and the management of irradiated fuel and GTCC waste. If necessary, additional funds may be recovered from the purchasers.

Maine Yankee has successfully litigated a couple of breach of contract damages claims against the Department of Energy (DOE) for failure to begin the removal of spent nuclear fuel (SNF)and GTCC waste from the site in 1998. A third breach of contract damages claim for the period 2008-20 12 is with the federal court for decision and additional damages claims against the DOE relating to the government's breach of contract are expected to continue as long as the irradiated fuel and GTCC waste remain on site.Annually, Maine Yankee submits the reports required by 10 CFR 50.75(f)(2), 10 CFR 50.82(a)(8)(v) and 10 CFR 50.82(a)(8)(vii) to establish how it satisfies the obligations defined in those regulations regarding the assurance of decommissioning funding and the status of funding for the management of irradiated fuel.

Maine Yankee Atomic Power Company OMY- 15-053/December 16, 2015/Page 3 10 CFR 72.3 0(b)(5) requires the licensee to define the volume of onsite subsurface material containing residual radioactivity that will require remediation to meet the criteria for license termination.

No subsurface material is assumed to require remediation regarding radionuclides.

This is justified because: 1) the ISFSI area was confirmed to be clean of radiological contaminants prior to the construction of the ISFSI; 2) the ISFSI area will be maintained clean of loose radiological contaminants during the storage period; 3) the irradiated fuel and GTCC waste are stored in sealed canisters;

4) nuclear activation of the Vertical Concrete Casks (VCCs), VCCs liners, and ISFSI are anticipated; the activation products will remain fixed during the storage period; and 5) if contamination of subsurface occurs during decommissioning activities, the contamination is expected to remain below the decommissioning criteria of 25 millirem per year Total Effective Dose Equivalent.

10 CFR 72.30(b)(6) requires a certification that financial assurance for decommissioning has been provided in the amount of the cost estimate for decommissioning.

Enclosure 2 provides the certification of financial assurance.

In addition, Enclosure 3 provides an estimate of the total costs associated with the Maine Yankee ISFSI for the management of irradiated fuel and GTCC waste at the Maine Yankee ISFSI through 2033.A summary of the revised DCE and the cost estimate for the management of irradiated fuel and GTCC waste at the Maine Yankee ISFSI will be incorporated into the Post-Shutdown Decommissioning Activities Report (PSDAR) and the License Termination Plan (LTP).If you have any questions, please do not hesitate to contact me at (860) 267-6426 x304.Respectfully, Carla M. Pizzella Vice President, Chief Financial Officer, and Treasurer

O 1.0 INTRODhUCTION The purpose of this study is to identify the costs associated with the decommissioning of the Maine Yankee (MY) Independent Spent Fuel Storage Installation (ISFSI). This estimate includes only the structures, systems and land within the NRC licensed area. The MY ISFSI is located within the site boundary of the former Maine Yankee nuclear power plant in the Town of Wiscasset, Maine. The site is approximately 1200 feet north of the former plant site in an area used as a vehicle parking lot. The NAC-UMS fuel storage and transport canister system chosen by MY is licensed by the NRC for both storage and transportation.

The ISF SI consists of the storage system and concrete storage pads, a Protected Area (PA) for spent fuel storage and a Security/Operations Building for equipment and staff. The PA contains 16, 3 foot thick concrete pads, each 31 feet by 31 feet. There are 64 dry storage casks on the 16 pads, 60 for spent fuel and four for sections of the reactor vessel internals that are classified as Greater Than Class C (GTCC) waste. Each vertical concrete cask has a two and a half-inch steel liner surrounded by 28.3 inches of reinforced concrete.Page 3 of 15 Knight Cost Engineering Services, LLCKCS21 20-30Rv0 KCES 2015 -2015-300 Rev. O 2.0

SUMMARY

Decommissioning is the safe removal of a facility or site from service and the reduction of radioactivity to a level that permits either the release of the property for unrestricted use and NRC license termination; or a restricted release of the property and NRC license termination.

This estimate includes all costs incurred to release the property for unrestricted use.On June 17, 2011, the NRC published a final rule amending its regulations to improve decommissioning planning.

The rule became effective on December 17, 2012. This rule requires licensees to report additional details in their decommissioning cost estimate.

To assist in the implementation of the new rule, the NRC issued NUIREG-1757, "Consolidated Decommissioning Guidance, Financial Assurance, Recordkeeping and Timeliness." NUREG-1757 does not apply to licensees under i0CFR Part 50 nor does it eliminate the need to follow Regulatory Guide 1.202 or NUJREG-1713.

It does provide additional information to support the development of the cost estimate.

This cost estimate was prepared in accordance with the guidelines provided in RG 1.202 and NUREG-1713.

In addition, it does take into account the guidelines identified in NUJREG-1757.

NUJREG- 1757 specifies that a contingency of 25% is to be included in the estimate.

This estimate takes exception to this contingency level for two reasons. First, the estimate is conservative in that the entire storage pad, concrete overpacks and overpack liners are assumed to be disposed of as potentially contaminated.

Second, the MY site has recently been successfully decommissioned, and the land released from the operating license, with the exception of land associated with the ISFSI and laydown area. The lessons learned from that project will be incorporated in the MY ISFSI decommissioning.

For this reason it is felt that a 10% contingency is adequate to cover unknown and unplanned occurrences.

The original Decommissioning Funding Plan for the Maine Yankee Independent Spent Fuel Storage Installation (ISFSI) to comply with 10 CFR 72.30(b) was submitted on December 17, 2012, with a revision submitted on January 8, 2013. 10 CFR 72.30(c) defines specific events that must be considered in the subsequent updates. Since the submittal of the original Decommissioning Funding Plan for the Maine Yankee ISFSI in December 2012: 1. No spills of radioactive material producing additional residual radioactivity in onsite subsurface material have occurred.2. Facility modifications that affected the ISFSI, including those that were implemented within the licensed area, were assessed for impact.3. There were no changes in authorized possession limits.4. No active decommissioning has occurred, thus, there have not been any actual remediation costs that exceed the previous cost estimate.Page 4 of 15 Knight Cost Engineering Services, LLC KCES 2015- 2015-300 Rev. 0 The total cost including contingency is $27.4 million, $21.6 million for radiological removal and$5.9 million for non-radiological removal.

activity costs and level of effort costs. The activity costs were developed utilizing a unit cost factor approach.

Site material quantities for concrete, steel and equipment where developed from site specific drawings.

Productivity factors were applied to these quantities to determine activity durations.

Labor crews were developed and applied to the material quantities to determine labor costs and person-hours.

The activity durations were used to develop a project schedule.The level of effort costs such as equipmenit rental and the General Contractor (GC) staff were developed based on the project schedule duration.

A rental equipment file was developed for the construction effort. The GC staff is assumed to be on-site for the duration of the project. The Oversight staff cost is another level of effort cost that. is included in the cost estimate.Bulk removal of the storage pad and concrete storage casks is assumed to be performed using an excavator with a hydraulic hammer attachment.

The steel liner will be segmented utilizing torch cutters. All of this waste will be trucked off-site for processing.

This leads to a large disposal volume; however, at a lower rate for bulk processing than for direct burial. In addition, there will be far less characterization and iterative decontamination.

Clean structures will be demolished using mechanical means and disposed of at a local landfill.In addition to the removal labor there is a dedicated waste packaging crew included in this estimate.This crew will consolidate, package and prepare containers for transportation.

The waste packaging crew is estimauted to remain on site for the duration of the project. This crew consists of 2 laborers; 1 Health Physics Technician; 1 Equipment Operator and 1 Foreman.Page 7 of 15 Knight Cost Engineering Services, LLCKES21-20530Rv0 KCES 2015 -2015-300 Rev. O 4.0 ASSUMPTIONS Following is a list of assumptions developed by KCES in completing this study. These assumptions are based on the most current decommissioning methodologies and site-specific considerations.

1. Component quantities were developed from actual plant listings.2. Concrete volumnes were developed from plant drawings.3. The oversight staff is assumed to be similar in size and configuration as it is currently.

4. The oversight staff positions and costs were supplied by the Company and represent September, 2015 salary and benefit data.5. Subcontractor base labor rates and fringe benefits were taken directly from the 2015 R. S. Means Heavy Construction Cost Data and adjusted to Maine based on the City Cost Indexes for Bath, ME.6. Activity labor costs do not include any allowance for delays between activities, nor is there any cost allowance for craft labor retained on-site while waiting for work to become available.

7. All skilled laborers will be supplied locally and hired by the Decommissioning General Contractor (DGC).8. The cost for Utility personnel assisting the DGC to develop decommissioning activity specifications is included in the Utility Staff costs.9. The separate DGC staff salaries, including overhead and profit, were determined by KCES.10. Transportation costs for LLW are included in the bulk disposal rate.11. The ISFSI Concrete Pad, VCC exterior concrete and VCC liner steel are assumed to be low-level radioactive wastes that will be disposed of at the Waste Control Specialists facility in Texas (a licensed facility) at $0.25 per pound.12. The following buildings are disposed of as Clean waste in local landfill.

A disposal rate of $91.80 per ton has been used in this estimate and is based on information provided in the 2015 R. S. Means Building Construction Cost Data.Compacted gravel around pads Security Fence Light Towers Security/Operations Building Paved area inside nuisance fence Page 8 of 15 Knight Cost Engineering Services, LIC ES01-21530Rv0 KCES 20!5 -2015-300 Rev. O Nuisance fence Miscellaneous Pads Miscellaneous structures Buried utilities SOB electrical service Road inside licensed area Vehicle barriers 13. All costs used in these calculations were current on September, 2015.14. The costs of all required safety analyses and safety measures for the protection of the general public, the environment, and decommissioning workers are included in the cost estimates.

15. It is assumed that all UMS canisters containing both spent fuel and GTCC will have been removed from site prior to the start of decommissioning.

16. Property taxes are included in the estimate at the current cost of $869,397 per year.17. Fees are included in the estimate at the current cost of $719,678 per year.18. Insurance costs are included in the estimate at the current cost of $582,818 per year.19. Legal costs are included in the estimate at the current cost of $200,000 per year.20. The decommissioning will be performed under the current regulations.

21. Removal of the pad and concrete overpacks will be performed in Tyvek coveralls.

Productivity rates have been adjusted to account for this.22. The removal of the berm is not included in the estimate.23. No subsurface material is assumed to require remediation regarding radionuclides.

This assumption is justified because: 1) the ISFSI area was confirmed to be clean of radiological contaminants prior to the construction of the 1SF SI; 2) the ISFSI area will be maintained clean of loose radiological contaminants during the storage period; 3) the irradiated fuel and GTCC waste are stored in sealed canisters;

4) nuclear activation of the VCCs, VCCs liners, and ISFSI pad are anticipated; the activation products will remain fixed during the storage period; and 5) if contamination of subsurface material occurs during decommissioning activities, the contamination is expected to remain below the decommissioning criteria of 25 millirem per year Total Effective Dose Equivalent Page 9 of 15 IKnight Cost Engineering Services, LLC KE 05 0530Rv KCES 2015-2015-300 Rev. O 5.0 SCHEDULE A scenario-specific schedule has been developed for estimate.Activity durations were determined based on the unit cost factor approach.

Plant material inventory quantities were developed from site specific material.

Unit rates for cost, man hours and schedule hours were applied to the material quantities.

From this calculation the removal or decontamination cost, total man hours and total schedule hours were detei'mined for an activity.The schedule hours are then entered into the schedule to determine project duration.

Two work crews are assumed for the concrete pad and concrete overpacks.

All other work was assumed to be performed by one crew. Work outside of the security fence will be performed in parallel with the work inside the fence. The total project duration is 17.97 months.Figure 5-1 provides the detailed decommissioning schedule.Page 10 of 15 Knight Cost Eri[ineering Services, LLC KCES 2015- 2015-300 Rev. 0 Figure 5-1 Project Schedule 2-i- a5*8 Eus0'am ay 6 r a m day 1$. 1114 We.* 1Wa4.3 INgig, S Devesaaaladbvew-Otedays Thu' 1/11114 Wed

$33,976 1.00 14.00 6.3 SECURITY Once spent fuel and G3TCC waste are removed from the site the security force will be significantly reduced. This estimate assumes a force of 13 guards, four supervisors and one manager. This will allow a security person level of 5 guards during work time and two guards all other times. .While this staff level may be high for industrial standards, we have decided to maintain the security staff at conservatively high level. The guard force was assumed to consist of various levels of guards and the rate used has been adjusted accordingly.
