Attached is the GE Hitachi Energy, LLC (GEH) additional information regarding decommissioning cost estimates for the shutdown VBWR and EVESR facilities (Reference 1).

This information was discussed between the NRG and GEH staff on October 19, 2021 (Reference 2) and requested by the NRG on October 21, 2021 (Reference 3).

Please contact me if you have any questions or would like to discuss this matter further.

Sincerely, x~P.

USNRC M210148 11/17/21 Page 1 of 2 Attachment Decommissioning Cost Estimate Information for VBWR and EVESR Shutdown Reactor Facilities Vallecitos Boiling Water Reactor (VBWR} NRC License DPR-1 The VBWR facility decommissioning cost estimate was originally developed in 1991 based on the estimates performed by Battelle Pacific Northwest (PNL) published in NUREG/CR-1756, "Technology, Safety and Costs of Decommissioning Reference Nuclear Research and Test Reactors", March 1982. This approach to estimating the cost of decommissioning the VBWR is in accordance with Regulatory Guide 1.159 "Assuring the Availability of Funds for Decommissioning Nuclear Reactors, Revision 2 issued October 2011. Cost adjustments for labor, energy, waste disposal .and other site-specific factors have been made at regular intervals or when significant changes such as facility remediations occur.

The cost estimate was reviewed and updated in 2019 by an independent third-party engineering firm experienced in preparing cost estimates and completing decommissioning-related services for the nuclear industry. The independent review included site reconnaissance and measurements, scaling factors from building volumes and footprints, interviews with site personnel, and comparisons to previous other decommissioning projects. The estimates are based on existing facility conditions and consider interim decontamination and dismantrement activities that have been completed. As a result of this independent third-party review, the cost estimate was increased from approximately $11.99 million to approximately $15.0 million.

As of year-end 2020, the estimate of the cost to complete decommissioning is approximately

$15.58 million. The VBWR financial surety bond was updated on April 1, 2021. No VBWR decommissioning work was performed in 2020 and there were no changes to the GEH master standby trust agreement.

  • Experimental Superheat Reactor (EVESR} NRC License DR-1 O The EVESR facility decommissioning cost estimate was originally developed in 1991 based on the estimates performed by Battelle Pacific Northwest (PNL) published in NUREG/CR-1756, "Technology, Safety and Costs of Decommissioning Reference Nuclear Research and Test Reactors", March 1982. This approach to estimating the cost of decommissioning the EVESR is in accordance with Regulatory Guide 1.159 "Assuring the Availability of Funds for Decommissioning Nuclear Reactors, Revision 2 issued October 2011. Cost adjustments for labor, energy, waste disposal and other site-specific factors have been made at regular intervals or when significant changes such as facility remediations occur.

The cost estimate was reviewed and updated in 2019 by an independent third-party engineering firm experienced in preparing cost estimates and completing decommissioning-related services for the nuclear industry. The independent review included site reconnaissance and measurements, scaling factors from building volumes and footprints, interviews with site personnel, and comparisons to previous other decommissioning projects. The estimates are based on existing facility conditions and consider interim decontamination and dismantlement activities that have been c.ompleted. As a result of this independent third-party review, the cost estimate remained approximately the same at $15.65 million.

USNRC M210148 11/17/21 Page 2 of 2 As of year-end 2020, the estimate of the cost to complete decommissioning is approximately

$15.85 million. The EVESR financial surety bond was updated on April 1, 2021. No EVESR decommissioning work was performed in 2020 and there were no changes to the GEH master standby trust agreement.
