Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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 energy release rates of fission products have been calculated by summation of the contributions of respective fission product nuclides. An attempt is made to refine the existing values of beta- and gamma-ray energy release rates at short times after fission by including information on more fission products, mainly short-lived ones. In the calculation, 443 radioactive and 125 stable nuclides are considered. The unknown nuclear data for short-lived nuclides are estimated theoretically or statistically. The Q values are obtained by using the semiempirical mass formula of Myers and Swiatecki. The beta-decay constant, λ, of a nucleus is derived from its Q value by using the empirical correlation between λ and Q., Feasibility of the method is evaluated through comparison of the calculated results with experiment. The results are in good agreement with the experimental results for the gamma-ray energy release rates at short times after the fission; usefulness of the estimated nuclear data is thus indicated. The calculated decay powers are in good agreement with the calorimetric measurements of Day and Cannon. The present results of decay power also agree well with the compilations by Shure and by Stehn and Clancy for the respective cooling times.
