The primary goal will be to prioritize a list of radioisotopes based on availability, usability, demand, strategic interests, and production methods. In addition, we will begin to design and test new nuclear battery systems (radioisotopes coupled to a semi-conductor matrix). Results from durability or efficiency tests of nuclear battery prototypes using radiation from accelerated beams can be compared to simulations to inform future designs. We will explore different radioisotope production methods and the possibility of activating a stable nuclide within a nuclear battery system, creating the radioisotope after assembly. Additionally, we will develop and commission a state-of-the-art isomer-depletion experimental setup, incorporating bremsstrahlung x rays from our superconducting linacs, along with a decay monitoring station to study different isotopes and their potential to be used to store and utilize the energy in isomers.
Benefit: The benefits of compact energy sources powered by radioactive nuclei cannot be exaggerated. Their unique ability to run for extended periods of time independently of environmental forces and their extreme energy density makes them perfect for a wide range of commercial and military applications. Low-power devices for use by the warfighter or mounted onto vehicles could be made smaller to reduce their load. These radioisotope-powered energy sources would greatly reduce the necessary equipment needed to power remote, off-the-grid encampments or devices. A radioisotope-powered device would also not age as fast as batteries and could provide reliable energy to inaccessible locations, with minimal waste or environmental impact. There is an existing market for radioisotope powered energy systems, both as RTGs used in aerospace applications and nuclear batteries used in low-power devices. In this Phase I base and option Niowave will prioritize a list of isotopes for development in RTGs and nuclear batteries and explore isomer options for energy storage devices. For RTGs and batteries, Niowave will reach both a commercial market and a DoD Market. As energy density improves, the applications and the market for these technologies will expand. RI energy storage devices will create a new market as the technology makes new applications possible. Niowaves initial RI energy storage device goals will center on meeting the needs of the warfighter and components of the Department of Defense. The US Defense Science Board has already identified applications for improved nuclear batteries. Energy dense power supplies could help to power unmanned surveillance devices, forward bases and off the grid encampments, undersea vehicles, and space ships. In Phase II, Niowave will more heavily rely on the expertise of its partners to prototype and test these products for use by the warfighter and for commercial applications.
