8 Next-generation test reactor The costs associated with maintaining DOE test reactors and converting them to use low-enriched uranium may make it practical to consider building a single new research reactor. INL work to design a next-generation test reactor is helping lead such a discussion at the DOE. Designs below for MATRIX Multiple Application Test Reactor for Irradiation Experiments aim to accommodate the diverse research needs of the DOEs many current customers. To create a reactor that could also use low-enriched uranium the design team is working in tandem with the INL experts designing such fuels. LeadershipNuclear cont. Nuclear Hybrid Energy Systems August 2012 Capability Development Plan LIMITEDDISTRIBUTION DistributionofthisdocumentislimitedtotheU.S. DepartmentofEnergyandtheIdahoNationalLaboratory unlessauthorizedbytheNSTorEESTALDs. Nuclear Hybrid Energy Systems The potential for sustainable use of nuclear fossil and renewable resources could be expanded through hybrid energy systems. Linking nuclear fossil and renewable energy systems could make more efficient use of excess heat and electricity that go to waste when systems are operated in isolation. This year INL led the creation of a Nuclear Hybrid Energy Systems Capability Development Plan which was issued to the DOE in August 2012. The plan describes development of computational tools intelligent monitoring and controls and user interfaces necessary to advance deployment of these systems. It also outlines a five-year approach toward demonstration that would involve collaborations with sister national labs more hybrid energy on pp. 12 35.
