Department of Energy

  • Washington, DC 20585 APR 21 2017 U'v-Y"1-0QOSO-D08 Mr. Jay Laughlin Chief N1iclear Officer and Head of Operations Louisiana Energy Services P.O. Box 1789 . .

Eunice, New Mexico 88231 D.er:1r Mr. Laughlin:

Thank you for your February 24, 2017, letter requesting a revised conversion and disposal cost estimate-for Depleted Uranium Hexafluoride (DUF6) generated by the URENCO Louisiana Energy Services (LES) centrifuge enrichment facility. The revision updates the previously provided estimate to LES ~ated May 19,. 2016.

The Department has incorporated the LES revised production estimates and included that volume of additional DUFG ip this updated cost estimate. We have also determined that the total cost of conversion contained in the w1certainty estimates/cost estimate range previously provided is still valid. Since the last estimate provided in*the May 19, 2016,.lettedCb)(4)  !(2016 dollars)], the ranJte has increased to (b)(4l (2016 dollars). Considering inflation, the updated estima~e range is (b)( 4l * (2017 dollars). This represents the best ayailable cost-estimate of the cost range to accept; process and dispose of LES DUF6 tails.

However, as the factors associated with this estimate are dynamic, they are subject to future adjustment.

If you have any questions or require additional infonnation, please contact Mr. Doug Tonkay, Director, Office of Waste Disposal, ?t (301) 903-7212"or.me at (301) 903-7514.

LES-17-00079-NRC P1op1iat~1y h1fu11natiu11 IO'ilARIIIII WRll&r 18 QFR 2.986 Enclosure 2 Updated Decomrnissioning Funding Cost Estimate

P1opiiato1; hafe1W1aliaR

'Nitk~eld IIRder 19 QFR i!.998 OVERVIEW This document presents the cost basis for calculating the estimated sum total for decommissioning funding required for the Centrifuge Assembly Building (CAB), other non-Separations Building Module structures; Separations Building Module (SBM) 1001 (including extension), SBM 1003, 16 cascades of SBM 1005 and depleted uranium tails produced through June, 2018 at the URENCO USA Facility in 2017 dolla~.

When License Amendment Request Number 07-004 was approved by the NRC on March 14, 2008, LES received authorization .to sequentially fund'decommlssioning for facility structures as they are placed Into service, rather than at the receipt of licensed material as originally considered in the LES License Application. In order to sequentially fund decommissioning for the facilities as they* are placed into service, a review of the estimated costs and underlying assumptions*was performed in order to determine how to allocate any* necessary costs for decommissioning of the respective facilities. *Table 12 below (as supported by Tables 1 through 11) and its associated notes reflect Total Decommission~ng Costs to account for the decommissioning funds for the CAB, Other Buildings, SBM 1001 (including extension), SBM 1003, 16 cascades of SBM 1005 and depleted uranium tails estimated to be produced through June, 2018.

It has been determined since the previous submittals (Refs. 1 and 3) that the CAB will sufficiently house the decommissioning efforts and, therefore, the costs for a separate building that were included in the earlier sµbmittals have been removed. The decontamination equipment can be retrofitted to; use for (?oth centrifuge types (i.e., TC-12 and TC-21) in SBM 1001, 'SBM 1003 and S.BM 1005. Incremental capital costs to

.accommodate both centrifuge types have been included. Earlier submissions assumed costs for removal and disposal of liners and ~arthen covers of the Treated Effluent Evaporative Basin (TEEB). Current project plans do not include the construction of a TEEB. All radioactive liquid effluents will b~ treated through the Liquid Effluent Collection and Treatment System (LECTS). Baseline costs have been inflated 13.98%

by using the change in the CPI-U index from th~ 2009 average to the 2017 April ending value. This funding estimate.submission includes the decommissioning funding required as of June, 2017 to include the CAB, other non-~eparation~ Building Module structures, SBM 1001, SBM 1003, 16 cascades. of SBM 1OQ5 and depleted uranium tails produced through June, 2018. Note that the submission *provides the decommissioning funding

  • estimate to include all cascades of Assay 10051and four cascades in Assay 1006 that will be placed in service before December 31, 2018. License Amendment Request Number 15-10was approved June 8, 2016 to ajlow LES to provision decommissioning funding on a cascade basis. The requirement t<>; submit for NRC review; 6 months_ prior to feed inlet is not applicable as current funding covers all planned centrifuges to be taken operational in SBM' .1005. Decommissioning I fundin including the first four cascades of Assay 1006 ls estimated at a value tjf (b)(4) *.
