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.

Many nuclear reactors are constructed of arrays of parallel channels. In order to carry out heat-transfer and flow-redistribution calculations for such arrays, proper boundary conditions must be assigned. These boundary conditions are not always obvious. In this paper, a method of formulating boundary conditions is discussed in which the stagnation streamline is used to define fictitious channel extensions upstream and downstream of the original parallel-channel configuration. This procedure is equivalent to defining a new parallel-channel configuration for which the boundary conditions are more clearly defined. A comparison of the calculated hydraulic parameters with the associated experimental results shows that the method is essentially correct.
