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.

Exponential and critical approach experiments have been performed to determine material buddings and extrapolation distances for several hexagonal lattice arrays of 2.1 wt% 235U enriched uranium tubes in light water. Tubes of two sizes were measured—2.33-in. o.d., 1.77-in. i.d.; and 1.38-in. o.d., 0.63-in. i.d. The arrays included clean lattices of uranium tubes; uranium tubes containing lithium aluminate target rods; uranium tubes with adjacent neutron absorbing columns; and two mixed lattices of 0.95 and 2.1 wt% enriched tubes—one with the 0.95 and 2.1 wt% tubes evenly distributed in the lattice, and the other with the 0.95 and 2.1 wt% tubes arranged in alternate rings. These experiments supplement data obtained in 1965 for 1.002, 1.25, and 1.95 wt% enriched uranium tubes. Critical parameters for these lattices, calculated with the HAMMER code, agree reasonably well with the measured results.
