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.

The use of thermoluminescent dosimeters (TLDs) to determine gamma-ray heating in a zero-power fast-reactor environment is considered. Generalized cavity-ionization theory is used to determine the relationship between the gamma-ray heating in the medium and the energy deposited in a TLD placed within the medium. The relationship is a function of the composition of the TLD and the surrounding medium, the size of the TLD, and the gamma-ray spectrum in the medium. Calculations are presented for several combinations of these variables. Data on the response of TLD materials to fast neutrons are reviewed. The fast-neutron-induced contribution to the thermoluminescent output relative to the gamma-ray-induced contribution is investigated. The relationship between the thermoluminescent response and the energy deposited in the dosimeter is also discussed.
