YANKEE ATOMIC ELECTRIC COMPANY 49 Yankee Road, Rowe, Massachusetts 01367 December 10, 2018 BYR 2018-025 Re: 10 CFR 72.4 and 10 CFR 72.30 ATTN: Document Control Desk U.S. Nuclear Regulatory Commission Washington, DC 20555 - 0001 :12-Ci~ I Yankee Atomic Electric Company Yankee Nuclear Power Station fudependent Spent Fuel Storage fustallation NRC License No. DPR-3 (NRC Docket No.50-029)
Subject:
Three-Year Update to the fudependent Spent fuel Storage fustallation Decommissioning Funding Plan Pursuant to the requirements of 10 CFR 72.30(c) and 10 CFR 70.4, Yankee Atomic Electric Company (YAEC) is providing the three"..year update to the Independent Spent Fuel Storage
, Installation (ISFSI) Decommissioning Funding Plan (DFP). Enclosure 1 updates the Yankee Nuclear Power Station (YNPS) ISFSI decomniissioning cost estimate and the cost estimate for the management of irradiated fuel and Greater than Class C Waste submitted with the previous YNPS ISFSI DFP on December 14, 2015 (Reference 1). 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 YNPS ISFSI remains unchanged.
10 CFR 72.30(c) defines specific events that must be considered in the subsequent updates.
Since the submittal of the updated Decommissioning Funding Plan for the ISFSI in December 2015:
- 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.
In addition, Y AEC complies with the requirements of 10 CFR 72.30(b)( 1) through (b)(6), as follows.
Yankee Atomi c Electric Comp any BYR2 018-0 25/De cembe r 10, 2018/Page 2 10 CFR 72.30(b)(1) requires the licensee to provide "information on how reasonable assurance will be provid ed that funds will be available to decommission the ISFSI.
" YAEC has established an account within its Nucle ar Decommissioning Trust (NDT) entitle d, "ISFS I Radiological Decom ," that segregates the funds for decommissioning of the ISFSI from the larger balance of funds for ongoin g manag ement of irradiated fuel and GTCC waste held in the NDT. Currently, the trust has sufficient funds to meet the revised DCE for the YNPS ISFSI.
10 CFR 72.30(b)(2) requires the licensee to provide a detailed cost estima te for decommissioning. Enclo sure 1 provides a revised DCE for the YNPS ISFSI that: 1) Utilizes. an independent contractor to perform the decommissioning activities in accord ance with 10 CFR 72.30(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 YNPS 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 YNPS ISFSI DCE estima tes the total cost to decommission the YNPS ISFSI to be $9.76 million and$ 10.00 millio n (in 2018 and 2019 dollars, respectively), inclusive of both radiological and non-radiolog ical 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 YNPS ISFSI, including the key assumptions and the justifi cation for their use.
10 CFR 72.30(b)(4) requires the licensee to provid e a description of the metho d 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
. YAEC will periodically reassess the decommissioning cost estimate in accordance with 10 CFR 72.30(c). On a periodic basis, Y AEC will submi t rate cases to Federal Energ y Regulatory Comm ission (FERC) that will include revise d cost estimates for decommissioning and the manag ement of irradiated fuel and GTCC waste. If necessary, additional funds may be recovered from the purchasers.
Y AEC has successfully litigated several breaches of contract damag es claims against the Depar tment of Energ y (DOE) for failure to begin the removal of spent nuclea r fuel (SNF) and GTCC waste from the site in 1998. An additional breach of contract damages claim for the period 2013 - 2016 is with tlte federal court for decision and additio nal damages claims against the DOE relating to the govern ment's breach of contract are expected to continue as long as the irradiated fuel and GTC:::C waste remain on site.
Annually, YAEC submi ts the reports required by 10 CFR 50.75(t)(2),
10 CFR 50.82(a)(8)(v) and 10 CFR 50.82(a)(8)(vii) to establish how it satisfies the obligations define d in those regulations regarding the assurance of decommissioning funding and the status of funding for the manag ement of irradiated fuel.
10 CFR 72.30(b)(5) requires the licensee to define the volum e 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 regard ing radionuclides.
. This is justifi ed because: 1) the ISFSI area was confirmed to be clean of radiological
Yankee Atom ic Electric Company BYR 2018-025/December 10, 2018/Page 3 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 Vertic al 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 durin g decommissioning activities, the contamination is expected to remain below the decommissio ning criteria of 25 millirem per year Total Effective Dose Equivalent. In addition, the site will meet the remediation standards established by the Commonwealth of Massachusetts.
IO CFR 72.30(b)(6) requires a certification that financial assura nce for decommissioning has been provided in the amount of the cost estimate for decommissio ning. Enclosure 2 provides the certification of financial assurance.
In addition, Enclosure 3 provides an estimate of the total costs associated with the YNPS ISFSI for the mana geme nt of irradiated fuel and GTCC waste at the YNPS ISFSI through 2036. A revised budge t is planned to be submitted to FERC upon receip t of proceeds from the DOE assod ated with the Comp any's Phase N litigation scheduled for trial in January of 2019. This revised budge t is expected to address a lengthier period of storag e and result in an increase in the overall costs of the management of irradiated fuel and GTCC waste.
A summ ary of the revised DCE and the cost estimate for the mana gement of irradiated fuel and GTCC waste at the YNPS ISFSI will be incorporated into the Post-Shutdown Decommissioning Activities Repo rt (PSDAR) and the License Termination Plan (LTP) following the FERC approval of a revised budget some time in calendar year 2019.

- 1. Backg round and Introd uction The Nuclea r Regula tory Commission (NRC) issued its final rule on Decom mission ing Plannin g on June 17, 2011,[1] with the rule becoming effective on Decem ber 17, 2012. Subpar t 72.30, "Financ ial assuran ce and recordk eeping for decommissioning," requir~ s that each holder of, or applica nt for, a license under this part must submit for NRC review and approv al a decomm issionin g funding plan that contain s inform ation on how reasona ble assuran ce will be provide d that funds will be availab le to decommission the Indepe ndent Spent Fuel Storage Installa tion (ISFSI).
In accorda nce with the rule, this letter provide s a detaile d cost estimat e for d_ecommissioning the Yankee
- Rowe (YR) Indepe ndent Spent Fuel Storage Installa tion (ISFSI) in an amoun t reflecting:
- 1. The work is perform ed by an indepe ndent contractor;.
- 2. An adequa te contingency factor; and
- 3. Release of the facility and dry storage system s for unrestr icted use, as specified in 10 CFR Part 20.1402 This letter also provides:
- 1. Identifi cation of the key assump tions contain ed in the cost estimat e; and.

ISFSI Decom missio ning Strate gy At the condu sion of the DOE spent fuel transf er proces s the ISFSI will be promp tly decommissioned (simila r to the power reacto r DECO N alterna tive) by remov ing and disposing of residu al radioa ctivity and verifying 'that remain ing materi als satisfy .NRC and the Comm onwea lth of Massa chuset ts releas e criteri a. *
The ISFSI consis ts of 15 dry storag e casks contai ning 533 spent nuclea r fuel assem blies used during operat ions. The NAC-MPC fuel storag e and transp ort canist er system was chosen by YR and is license d by the NRC for both storag e
and transp ortatio n. The NAC-MPC system consis ts of a multi- purpos e spent fuel storag e canist er and a vertica l concrete and steel overpack. Each vertica l
concre te cask has a three-a nd-a-h alf-inc h steel liner surrou nded by 21 inches of reinfor ced concrete. Constr uction of the concre te storag e pad and vertica l
-concr ete and steel* storag e was completed during decommissio ning.
Transf erring the spent fuel from the spent fuel pool to the storag e casks was compl eted in March of 2003.
In additio n to the 15 spent fuel storag e casks there is one cask contai ning segme nted section s of the reacto r intern als classif ied as Greate r than Class C
waste. The multi- purpos e canist ers will be transf erred directl y to the DOE.
After remov al of the MPC caniste rs, the remain ing overpa cks are assum ed to have residu al radioa ctivity due to some minor level of neutro n-indu ced activa tion as a result of the-lon g-term storag e of the spent fuel.

Table 1 provides the signi fican t quan tities and physical dime nsion s used as the basis in developing the ISFS I decommissioning estim ate.
- 5. Key Assu mpti ons/ Estim ating Appr oach The decommissioning estim ate is based on the confi gurat ion of the ISFS I expected after all spen t fuel and GTCC mate rial has been removed from the site. The confi gurat ion of the ISFS I is based on the assum ption s assoc iated with DOE 's spen t fuel acceptance, as previ ously described.
The decommissioning estim ate is based on the prem ise that the inner steel-liner s of the concr ete overpacks will conta in low levels of neutr on-in duced resid ual radio activ ity that would neces sitate reme diatio n at the time of decommissioning. At the reque st of Yank ee Atomic Electric Comp any (YAEC) all 15 overp acks .and liner s which conta ined spen t fuel canis ters are assum ed to be affected, i.e., conta in resid ual radio activ ity. The rema ining GTCC overp ack is conse rvativ ely assum ed to be treat ed in the same mann er.
It is assum ed for this analy sis that the ISFS I pad will be conta mina ted. As such, the pad will be remo ved and disposed of as low-level waste The subsu rface mate rial of the ISFS I site is not expected to conta in any signi fican t resid ual radio activ ity that will requi re reme diatio n to meet the criter ia for license termi natio n.
Decommissioning is assum ed to be perfo rmed by an indep ende nt contractor.
As such, essen tially all labor, equip ment , and mate rial costs are based on natio nal avera ges, i.e_., costs from natio nal publi catio ns such as RSM eans Build ing Cons tructi on Cost Data (adju sted for regio nal varia tions ), and labor atory service costs are based on vend or price lists.
Those craft labor posit ions are expec ted to be provided locally. YR, as licensee, will oversee the site activ ities.
The Utili ty overs ight staff is assum ed to be simil ar in size and configuration as it is curre ntly.
The following build ings are disposed of as clean wast e in a local landfill.

NUREG-1757.[31 specifies that a conting ency of 25% is to be included in the estimat e. This estimat e takes exception to this conting ency level, at the reques t of YAEC, for two reasons . First, the estimat e is conserv ative in that the entire storage pad, concret e overpac ks and overpac k liners are assume d to be dispose d of as potenti ally contam inated. Second, the YR site has recentl y
. been successfully decommissioned, and the land release d from the operati ng license, with the exception of land associa ted with the ISFSI and a laydown area. The lessons learned from that project will be incorpo rated in the YR ISFSI decommissioning. For these reasons , it is felt that a 10% contingency is adequa te to cover unknow n and unplan ned occurrences.
The estima te is limited to costs necessa ry to termin ate the ISFSI's NRC license and meet the §20.1402 criteria for unrestr icted use. Disposi tion of rel~ase d materia l and structu res is outside the scope of the estimat e.
The effects, if any, since the last submit tal of the ISFSI decommissioning funding plan of the following events listed in 10 CFR 72.30(c)(l)-(4) have been specifically conside red in the decommissioning cost estimat e:
(1) Spills of radioac tive materia l produc ing additio nal residua l radioac tivity in onsite subsurf ace materia l: There have been no spills at the ISFSI.
(2) Facility modifications: There have been no facility modifications in the past three years that affect the decommissioning cost estimat e.
(3) Change s in authori zed possess ion limits: There are no change s in authori zed possess ion limits that affect the decommissioning cost estimat e.

Yankee Atomic Electr ic Compa ny Attach ment 1 Yankee Rowe ISFSI Page 5of 10 (4) Actual remedi ation costs that exceed the previou s cost estimat e: No actual remedi ation costs have been incurre d, so no actual remedi ation costs exceed the previou s cost estimat e.
- 6. Cost Estima te The estima ted cost to decommission the ISFSI and release the facility for unrestr icted use is provide d in Table 2. The cost has been organiz ed into four phases, including:
- An initial plannin g phase - empty overpac ks are charact erized and the specifications and work procedu res for the deconta minatio n (liner removal) developed. *
- The remedi ation phase - residua l radioac tivity is remove d, packag ed in certifie d waste contain ers, transpo rted to the low-level waste site, and dispose d of at low-level waste.
- The license termina tion phase - license termina tion surveys , indepe ndent 1
surveys are completed, and an applica tion for license termina tion submit ted.
- Site restora tion - While not require d by the NRC this estimat e include s the cost to remove and dispose of all non-co ntamin ated structu res. A list of all structu res include d in this estimat e is provide d in Table 3.
In additio n to the direct costs associa ted with a contrac tor providi ng the decomm issionin g services, the estimat e also contain s costs for the NRC (and NRC contrac tor), YR's oversig ht staff, site securit y (indust rial), and other site operati ng costs.
For estima ting purpose s, it should be 'conser vativel y assume d that all expend itures will be incurre d in the year following all spent fuel removal.
