ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

Transmission measurements on natural iron samples were carried out at the Nevis Synchrocyclotron to determine the minima in the total cross section occurring between 10 and 500 keV. We used the NVS 200-m time-of-flight system and obtained an effective fwhm resolution of ≈0.6 nsec/m for these measurements. Values of the total cross section at the minima points were determined by the transmission-of-the-difference method for four thick samples ranging in inverse thickness (1/n) = 1.53 to 0.38 b/atom. Our value of the cross section at the important minimum at 24.4 keV is (0.51 ± 0.02) b. This value is close to the one appearing in the KEDAK data file (0.557 b), but considerably higher than the values in ENDF/B-I (0.15 b) and ENDF/B-II (0.285 b) files. Our value is in agreement with recent integral spectral measurements at RPI which show a preference for a value close to the KEDAK evaluation.
