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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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 neutron multiplicities P(n) in the spontaneous fission of 246Cm, 248Cm, and 252Cf have been measured in a 3He neutron counter assembly. The efficiency ∈ for detection of a single neutron was measured to be 0.360, based on (average number of neutrons per fission) = 3.73 for 252Cf spontaneous fission. Using this value of ∈ and assuming a Gaussian distribution p(v) for the emitted neutrons, we fitted our observed P(n), corrected for small background and pile-up effects, to the model by the method of least squares in which the Gaussian width σv and were the parameters of fit. Values of p(v) were then calculated from the resulting Gaussian function. In the case of 252Cf, our values of p(v) agree well with literature values; the p(v) values for the curium isotopes have not been measured previously as far as we know. The values of for both 246 Cm and 248Cm fall on a straight line through existing experimental values for the nuclides 242Cm, 244Cm, and 250Cm in a plot of versus mass number; our values were 2.86 ± 0.06 and 3.14 ± 0.06 for 246Cm and 248Cm, respectively.
