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.

Electrical conductivities of weakly ionized nuclear plasmas were computed by numerically solving an electron Boltzmann equation. A pure 3He gas and 3He-Na gaseous mixtures were analyzed. The gases are ionized by fast ions (0.19-MeV tritons and 0.59-MeV protons), which are generated from in situ neutron-3He nuclear reactions. The results show that the electrical conductivity of the 3He-Na gaseous mixtures is higher than that of the pure helium gas because of the enhanced ionization of seeded sodium atoms by subexcitation electrons. This effect is not included in a standard Maxwellian model. An analytical formula of W values for gaseous mixtures was suggested to incorporate the effect of subexcitation electrons. The formula can be applied to analyze chemically complex systems.
