The US Department of Energy (DOE) has selected nine domestic projects to receive nearly $20 million in funding for cost-shared research and development for advanced nuclear technologies.
These awards are through the Office of Nuclear Energy’s (NE) funding opportunity announcement (FOA) U.S. Industry Opportunities for Advanced Nuclear Technology Development and are the second group selected under this solicitation. The first group was announced on 27 April 2018. (Earlier post.)s
Subsequent quarterly application review and selection processes will be conducted over the next five years. The Department intends to apply approximately $30 million of additional FY 2018 funding to the next quarterly award cycle for innovative proposals under this FOA.
The solicitation is broken into three funding pathways:
First-of-a-Kind (FOAK) Nuclear Demonstration Readiness Project pathway, intended to address major advanced reactor design development projects or complex technology advancements for existing plants which have significant technical and licensing risk and have the potential to be deployed by the mid-to-late 2020s.
Advanced Reactor Development Projects pathway, which allows a broad scope of proposed concepts and ideas that are best suited to improving the capabilities and commercialization potential of advanced reactor designs and technologies.
Regulatory Assistance Grants pathway, which provide direct support for resolving design regulatory issues, regulatory review of licensing topical reports or papers, and other efforts focused on obtaining certification and licensing approvals for advanced reactor designs and capabilities.
DOE also announced voucher awards selected under the Gateway for Accelerated Innovation in Nuclear (GAIN) initiative. All awards selected under this FOA and the GAIN Voucher Request for Assistance (RFA) will be funded under existing NE programs.
The following project was selected under the FOAK Nuclear Demonstration Readiness Project pathway:
Calendar Year 2018 Activities for Phase 2 of NuScale Small Modular Reactor project. NuScale Power will build on Phase 1 project activities to advance the licensing and design maturity to meet a commercial operation date of 2026 for the first NuScale plant. The specific project scope being funded represents calendar year 2018 activities associated with the next phase (Phase 2) of the US product realization effort required to bring the NuScale design to market.
Specific project activities include completion of the independent verification and validation licensing report; completion of the reactor building design optimization; and conduct of level sensor prototypic testing. There is potential for extension of this award to complete calendar year 2019 activities associated with Phase II of the NuScale project if the 2018 activities are completed successfully.
DOE Funding: $7,000,000; Non-DOE: $7,100,000; Total Value: $14,100,000
The following five projects were selected under the Advanced Reactor Development Projects pathway:
Conceptual Engineering for a Small Modular Reactor Power Plant Based on Lead-Bismuth Fast Reactor (LBFR) Technology. This work proposed by Columbia Basin Consulting Group aims to develop a pre-conceptual design and preliminary cost estimate for a lead-bismuth small modular reactor.
DOE Funding: $400,000; Non-DOE: $100,000; Total: $500,000
Reactor Plant Cost Reduction to Compete with Natural Gas Fired Electrical Generation. Under this proposal, GE-Hitachi Nuclear Energy will examine ways to reduce reactor plant construction and maintenance costs on their BWRX-300 small light water reactor concept through (a) elimination of Loss of Coolant Accidents (LOCAs), (b) the use of an embedded (below grade) design and construction and (c) the use of pooled off-site resources that can be applied simultaneously at multiple sites.
DOE Funding: $1,925,038; Non-DOE: $481,260; Total Value: $2,406,298
Experimental Verification of Post-Accident Integrated Pressurized Water Reactor (iPWR) Aerosol Behavior, Phase 3. – The Electric Power Research Institute will further improve the models used to estimate the post-accident radionuclide releases from integral pressurized water reactors (iPWRs) with a goal of reducing regulatory requirements for emergency planning zones.
DOE Funding: $1,119,699; Non-DOE: $279,923; Total Value: $1,399,622
Fluorination of Lithium Fluoride-Beryllium Fluoride (FLiBe) Molten Salt Processing. Flibe Energy has teamed with Pacific Northwest National Laboratory to examine the use of nitrogen trifluoride as an agent to remove uranium from a molten-salt fuel mixture as a preliminary step for the removal of fission products.
DOE Funding: $2,101,982; Non-DOE: $525,500; Total Value: $2,627,482
Advancing and Commercializing Hybrid Laser Arc Welding (HLAW) for Nuclear Vessel Fabrication, Including Small Modular Reactors. Holtec International will advance hybrid laser arc welding for use in fabrication of small modular reactors and other nuclear components to achieve improvements in the reliability, quality and cost associated with traditional multi-pass welding.
DOE Funding: $6,314,612; Non-DOE: $6,314,612; Total Value: $12,629,224
The following project was selected under the Regulatory Assistance Grant pathway:
Regulatory Support for Advanced Light Water Reactor Deployment: Advanced Boiling Water Reactor Source Term Reduction. Pittsburgh Technical Institute will develop a technical basis to reduce source terms associated with Level II and Level III probabilistic risk assessment for advanced boiling water reactor designs.
DOE Funding: $498,000; Non-DOE: $124,500; Total Value: $622,500
DOE selected two companies to receive GAIN technology development vouchers in this second review cycle. The companies selected are Yellowstone Energy (Knoxville, TN) in the amount of $160,000, and ThorCon US (Stevenson, WA) in the amount of $400,000.
