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.

An improved data processing method is developed for pulsed-neutron measurements in a multiplying medium. The characteristic feature of the method is to determine the value of the prompt-neutron decay constant a as accurately as possible by removing the delayed-neutron decay component from the raw experimental data. The delay ed-neutron decay component is estimated to be the deviation of the response of a one-point reactor from a single exponential decay for repeated pulsed-neutron bursts. It is obtained by taking account of the first and second post-neutron bursts. From the application of the method to some test data provided by calculation and to experimental data from pulsedneutron experiments in the Semi-Homogeneous Ex-periment it is found that the usual data processing method, disregarding the slowly decaying delayedneutron mode, should underestimate the value of a by ∼4% in a near-critical multiplying medium having a neutron lifetime of ∼1 msec.
