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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The radiochemical reactions between methane and tritium were vicariously chosen for the evaluation of an omegatron type mass spectrometer and a laser Raman spectrometer in view of their analytical application in tritium systems. Assessment of the omegatron was extended beyond previous work on the quantitative analysis of all hydrogen isotopes and stable helium isotopes to include the determination of tritiated hydrocarbons. As opposed to mass spectrometry, laser Raman spectroscopy is an absolute method, which in principle is applicable to all polyatomic gases. For the employment in tritium systems an uhv-tight stainless steel gas cell using windows mounted in CF flanges with a flatness better than 1 lambda was constructed and tested. The Raman spectra of H2, HD and D2 were measured and the pure rotation and rotation vibration branches assigned. The fundamental vibrations of methane and deuterated methanes have also been identified. First kinetic data on the β-radiation induced exchange reaction between tritium and methane have been obtained with an omegatron.
