DoE Awards $60M for Advanced Nuclear Energy R&D

  • The U.S. Department of Energy (DOE) has selected 13 projects to receive approximately $60 million in federal funding for cost-shared research and development for advanced nuclear technologies.
  • These awards are the first under DOE’s Office of Nuclear Energy’s U.S. Industry Opportunities for Advanced Nuclear Technology Development funding opportunity announcement (FOA).
  • Subsequent quarterly application review and selection processes will be conducted over the next five years.
  • DOE intends to apply up to $40 million of additional FY 2018 funding to the next two quarterly award cycles for innovative proposals under this FOA.

The selected awards underscore the importance of the private-public partnerships engaged in by U.S. companies in order to share expertise needed to successfully develop innovative nuclear technologies.

U.S. and France ink plan for work on advanced fast neutron sodium-cooled reactors and artificial intelligence

US Energy Secretary Rick Perry and François Jacq, Chairman of France’s Alternative Energies and Atomic Energy Commission (CEA), this week signed two Statements of Intent (SOIs). The signing ushers in a new era of DOE-CEA research and development (R&D) cooperation with enhanced collaboration in the area of advanced fast neutron sodium-cooled nuclear reactor technologies and new collaboration in the area of artificial intelligence.

The new cooperation on the development of advanced fast neutron sodium-cooled reactors will explore areas of collaboration ranging from modeling, simulation, and validation to technology testing, access to supply chain, experimental facilities, and advanced materials.

Technology Notes

Fast reactor concepts are typically classified by their coolant—i.e., sodium-cooled fast reactor (SFR); lead- or lead-bismuth eutectic (LBE)-cooled fast reactor (LFT); and gas-cooled fast reactor (GFR). All fast reactor concepts are based on the same basic principles:

  • No (intentional) neutron moderators (water or graphite), resulting in a “fast”(or “hard”) neutron energy spectrum compared to thermal reactors (LWRs and HTGRs).
  • Improved neutron economy due to larger fission-to-capture cross section ratio and greater number of neutrons per fission at high-energies.
  • Fast neutron spectrum can also be used for breeding or transmutation of transuranic waste products.
  • Higher enrichment is required to achieve criticality (in comparison to thermal reactors).

High core outlet temperatures allow greater thermal efficiency (-40%) for energy conversion; the fast reactors also have a high core power density (~5x compared to a LWR) and the potential for a long core life.

The SFR uses liquid sodium as the reactor coolant, allowing high power density with low coolant volume fraction and operation at low pressure. While the oxygen-free environment prevents corrosion, sodium reacts chemically with air and water and requires a sealed coolant system.

Scope of Cooperation

DOE and CEA cooperate on a wide range of technology areas, including the fields of civil-nuclear energy, basic science, environmental management, renewable energy, and energy management systems. Such cooperation plays a key role in maintaining cost-competitiveness and reliability across the energy mix, benefiting both countries in the enhancement of transatlantic energy security.
