New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Advances in high-current linear accelerator technology since the design of the Fusion Materials Irradiation Test facility have increased the attractiveness of a deuterium-lithium neutron source for fusion materials and technology testing. The conceptual design of such a source, which is aimed at meeting the near-term requirements of the high-flux high-energy International Fusion Materials Irradiation Facility, is discussed. The concept employs multiple accelerator modules providing deu-teron beams to two liquid-lithium jet targets oriented at right angles. This beam/target geometry provides much larger test volumes than can be attained with a single beam and target and produces significant regions of low neutron flux gradient. A preliminary beam dynamics design has been obtained for a 250-mA reference accelerator module. Neutron flux levels and irradiation volumes were calculated for a neutron source incorporating two such modules, and interaction of the beam with the lithium jet was studied using a thermal-hydraulic computer simulation. Approximate cost estimates are provided for a range of beam currents, and a possible facility staging sequence is suggested.
