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.

This paper considers a system that involves the attack of water vapor on a graphite cylinder such as occurs in gas-cooled nuclear reactors. Its purpose is to describe such a system, develop a mathematical model for it, and provide a means of solving the model. This is accomplished by first discussing the transport and rate mechanisms of the system: convective transport of reactants by an inert flowing stream, solid-state diffusion into a porous conduit, and chemical reaction with the conduit material. Based on these mechanisms, mass balance equations are written which give a mathematical description of the system. This mathematical model is then solved by two essentially different numerical techniques.
