BACKGROUND: This experiment is envisioned to support space reactor applications as well as terrestrial microreactor applications. Reactor designs for power levels up to 100 kWe have the potential to be vehicle-mounted to make them truly mobile, leading to a fast-response provision of power and heating for remote operations at a cost-competitive form. Compact reactor designs of this kind currently do not have a validated nuclear benchmark which is limiting their commercial adoption. This experiment is specifically planned to fill existing performance validation gaps by producing a nuclear experimental dataset for use by government agencies and private industry. The intent is to perform technology maturation and improve technology readiness levels of the components integrated in the system design. While the experiment is targeting government use cases for the intended core design, the protoboard configuration and experimental results can allow for interested industry organizations to revise individual component designs and to cost-effectively mature their own product use cases. DESCRIPTION: This small fission reactor experiment (culminating in a TRL 4/5 protoboard) is designed to validate neutronic behavior of hydride moderated compact nuclear reactors. Los Alamos National Laboratory Directed Research Development (LDRD) “Multi-Scale Kinetics of Self-Regulating Compact Reactors” first developed a hydride moderated reactor design and fabricated key core components including yttrium hydride (YH) moderator and high-density particle fuel compacts. Recent technology maturation efforts sponsored under DOE’s Microreactor Program and NASA’s Fission Surface Power projects have extended development of zirconium-hydride (ZrH) and yttrium-hydride (YH) for operating temperatures up to 1100 K with a lifetime of 10 years. NASA Fission Surface Power (FSP) studies have shown moderator and fuel advancements can produce compact fission power designs that are sufficiently lightweight for space exploration and mobile terrestrial applications. The reactor experiment is envisioned to accommodate testing with variable fuel systems to enable gathering of physics data across a range of design options. This experiment will demonstrate fission reactor materials that enable a low-mass design using a high assay low enriched uranium (HALEU) fuel form which has potential application as a lunar surface and terrestrial power source. The baseline design currently targets a power output between 100 kWth and 200 kWth utilizing the Advanced Gas Reactor TRISO fuel form, a metal-hydride moderator (ZrH or YH), a beryllium reflector, a graphite core block, and heat pipes for thermal transfer. A power conversion system is not part of the baseline design and is one example of an opportunity for in-kind participation. The system is versatile enough to be able to accommodate either Brayton or Stirling power conversion systems. Alternative fuel types and other key baseline design elements can be interchangeable depending on the level of industry interest and participation. Once the experiment is operational, multiple parameters will be monitored to include neutron flux, temperature, and pressure within the core along with power output and occupational radiation levels. This data set will be collected and distributed to all stakeholders and contributors for further analysis.
