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.

A model is developed to investigate the response of a coupled two-core reactor to a neutron pulse. Various coupled cores with symmetrical and asymmetrical configurations and compositions are studied. The fundamental spatial mode splits into two distinct decaying submodes. The reactivity of a coupled-core system is defined, and two methods are given for its measurement. The model is compared with results of pulsed-neutron experiments performed on a light-water-moderated, coupled, compact two-core reactor fueled with uranium of 90% 235U content and reflected by both light water and graphite in either symmetrical or asymmetrical configurations
