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.

Thermohydraulic feedback effects in a boiling water reactor during pressure transients are analyzed. Transient calculations are carried out with the one-dimensional nonlinear plant model ALMOS. A reference case of the analysis is a turbine trip without bypass (loss of heat sink) and delayed scram action. Neutron flux and fuel temperatures are investigated with respect to such feedback parameters as the Doppler coefficient, moderator feedback, and heat generation in the coolant. The amount of heat generated in the coolant is recognized as an important parameter. The sensitivity of the system to this parameter is further analyzed qualitatively by frequency response methods.
