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 control system is described which will shut down a reactor in close to the minimum time that will allow subsequent restart on demand, despite fission product buildup. Errors in the reactor model, restrictions on operating conditions, and plant perturbations are taken into account. The system uses an on-line computer, requires no extra reactor instrumentation, and provides the operator at all times with an estimate of the minimum time to transfer the reactor from its current state to a suitable shutdown condition. During normal operating conditions, the operator may use the system to evaluate strategies satisfying various restart conditions. The results of simulation tests on the system are included.
