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 method for the analysis of hydrogen in uranium metal by mass spectrometry is described. The samples are introduced into a tube containing helium at atmospheric pressure. Hydrogen gas evolved from the heated sample is mixed with a helium gas stream flowing through the tube and over the sample at a constant rate. The effluent gas mixture is monitored at M/e 2. The resulting rate-of-evolution curve is integrated with respect to time by an electronic integrator. The empirical number so obtained is directly proportional to the hydrogen content of the metal. The method has been adapted to the Bendix Time-of-Flight and the Consolidated Electrodynamics Model 21-611 Mass Spectrometers. A description of the associated instrumentation is presented. The determination requires from 3 to 10 min. on the mass spectrometer, depending on the size of sample and the hydrogen content of the metal. Precision comparable to that of the classical vacuum technique is obtained. The technique described is also adaptable to the study of hydrogen diffusion through uranium metal.
