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.

A high-intensity, high-energy neutron source for fusion materials testing is proposed. Utilizing the 1H(t,n)3He neutron source reaction and bombarding a thick (totally absorbing) hydrogen-rich target with an intense beam of 21-MeV tritons provides a powerful continuous-energy-spectrum neutron source. The global spectrum of such a source is almost flat over the energy range from ∼1 to 14 MeV and exhibits a sharp energy cutoff level at 14.6 MeV. To meet near-term needs for fusion materials testing, a source concept is considered that involves multiple linear accelerator modules providing two 250-mA triton beams to bombard two water jet targets that face each other and irradiate the same test volume. Calculations of the source properties from well-established neutron production cross-section data for the 1H(t,n)3He reaction predict a test volume of 4.2 dm3 in which an average flux of ≥1 × 1014 n·cm-2·s-1 is achieved. The relevant properties of this source and the possibility of its realization, well within the limits of present technology, are discussed.
