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.

The International Criticality Safety Benchmark Evaluation Project (ICSBEP) provides a handbook of descriptions, evaluations, and models of experiments with fissionable material. The "International Handbook of Evaluated Criticality Safety Benchmark Experiments" (ICSBEP Handbook) is useful for criticality safety analysts and nuclear-data evaluators for validation of neutron transport codes and nuclear cross-section sets. Each of the four main parts of the ICSBEP document provides valuable information. The four parts are as follows: Part 1, detailed description of the experiment; Part 2, evaluation of experimental data to obtain parameter values that define the model and their uncertainties; Part 3, derivation and concise description of the benchmark model; and Part 4, sample calculation results. The ICSBEP Handbook provides a practical, standardized format for documenting nuclear experiments.Valuable, previously unknown data are often discovered during the evaluation process. Besides these discoveries, many other things have been learned during this first decade of evaluating and providing benchmark models of experiments. The current method is described in order to improve understanding of what is required to evaluate benchmark experiments for validation purposes.
