GE VALLECITOS FACILITY DECOMMISSIONING AND CLOSURE COST ESTIMATES The estimated total cost for the decommissioning and closure of the Vallecitos facility is ____ million (2009) dollars. The cost breakdown is shown in the following table. This estimated total cost includes the cost of special-purpose equipment, materials, labor, site support services, waste packaging, transportation, burial, and other miscellaneous owner expenses.

The estimated total cost assumes an efficient decommissioning and closure activity but a 30% contingency is added to allow for unforeseen problems that might arise during the activity.

The estimated costs were developed using reasonable and documented estimates provided by knowledgeable personnel in the various GE Nuclear functions and off-site support groups.

PLANT-SPECIFIC DECOMMISSIONING AND CLOSURE ASSUMPTIONS The availability of site facilities and other assumptions that contribute to the decommissioning and closure activities are as follows:

  • The plant will have had normal operations in the interim prior to decommissioning and closure, i.e., no unplanned events have occurred to perturbate the condition of the facility at the time of decommissioning and closure.
  • All __________________________will have been removed from the site prior to the initiation of decommissioning and closure activities.
  • An off-site disposal facility will be available to accept low level and high-level wastes generated during decommissioning and closure.
  • Similar safety control practices in place for plant operations will be utilized for decommissioning and closure activities.
  • Non-contaminated equipment and facilities will be disposed of by standard corporate practices.
  • Dismantling will be programmed and time phased to maintain waste segregation, decontamination and monitoring capabilities for as long as required.
  • A11 hazardous waste will be removed to eliminate the need for long-term monitoring.

  • Decommission and closure activities will include reevaluating the latest technology for decontamination techniques and equipment in order to utilize those features that are the most cost effective and efficient.
  • Decommission and closure activities will allow NRC and EPA approval to terminate the site radioactive material license and use the site for unrestricted, non-nuclear purposes.

GE VALLECITOS FACILITY KEY DECOMMISSIONING COST ASSUMPTIONS Assumptions relative to the decommissioning cost estimates are as follows:

  • Major decommissioning tasks include decontamination or dismantling of radioactive facility components, waste packaging, restoration of contaminated areas as necessary, final radiation status surveys and if necessary, site stabilization and long term surveillance.
  • Labor costs include basic wages and benefits for professional salaried workers. Contract worker costs performing decommissioning related tasks include overhead costs and a sufficient contractor profit to allow an independent third party to perform the decommissioning project.
  • Planning and preparation costs include activities such as preparing a detailed decommissioning plan, obtaining other state or local authorizations, developing work plans, performing staff training, procuring special equipment, and performing a pre-characterization study.
  • Inspection consultation costs include industrial safety, environmental protection, material control, security, quality, and independent assessments.
  • Lab fee costs include sample transport, testing and analysis at an offsite third party laboratory.
  • Shared services include support functions such as finance, human resources, facilities engineering, and information technology.
  • Insurance for the facility is an estimate of the annual insurance premium for both nuclear and conventional insurance based on actual rate experience.
  • Radioactive waste disposal costs are estimated at an average disposal rate of $____ per cubic foot.
  • Transportation costs assume 90% of the total waste volume will qualify as low-level radioactive waste (LLRW) for disposal at Energy Solutions, Clive, Utah and 10% of the total waste volume will be high-level waste (HLW) for disposal at an approved waste disposal facility.

Transportation costs include waste containers, packing materials, Page 4 of 5

7/2/09 Attachment 2 (Non-Proprietary Version) permits and documentation. Shipping by truck is based on an estimated rate of $____ per mile.

  • Decon equipment costs include special purpose containment and filtration systems, volume reduction and cutting devices, cranes and lifting mechanisms, personal protective equipment, and miscellaneous supplies.
  • The cost for regulatory licensing and inspections includes reviews, approvals, ongoing inspections and final license termination and is estimated based on the current hourly rate of $257 established by the NRC.
