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.

A spatial-averaged model of boiling flow in an electrically heated vertical pipe is used to investigate and explain experimental data of various labroatories. The agreement with data is good over a variety of conditions ranging in pressure from atmospheric to 1000 psia, and in heated length from 2 to 16 ft. Two slip-ratio correlations are compared in testing the model against the stability data; the correlation of Bankoff being less successful at low subcooling than the modified Bankoff correlation due to Jones. A value of Bankoff's K recommended by Kholodovski is also compared for Spigt's experiment. The crucial boiling length, where the system is least stable, is used to demonstrate the dependence of stability on heating rate, flow rate, and degree of subcooling. In particular, it is shown that with the Bankoff-Jones slip ratio, an increase in the ratio of heating rate to flow rate invariably leads to less stable conditions. On the other hand, an increase in subcooling leads to less stable conditions only when the degree of subcooling is less than that at the crucial boiling length.
