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.

Expressions are derived for the output, and time derivative of the output, of the simple diode pump circuit corresponding to an input pulse rate which is increasing exponentially with time. Solutions are obtained in numerical form for a series of values of the diode pump parameters. By a linear superposition of the outputs it is possible to predict the transient behavior of the multiple diode pump type of logarithmic rate meter and of the period signals derived from the output. The fluctuations or “noise” in the period meter output signal for random input pulses is also calculated for this type of rate meter. A comparison based on transient response and noise behavior shows the multiple diode pump circuit to be potentially superior to the simpler logarithmic diode type of rate meter.
