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 Sandia National Laboratories Particle Beam Fusion Accelerator PBFA II is expected to produce significant bremsstrahlung on every shot during 30 MV operation. Shielding specific electronic components from the intense bremsstrahlung environment is an important consideration. We describe new 3-D Monte Carlo electron-photon transport simulations of the PBFA-II facility that include a more efficient version of the next-event-estimator calculation and final design information for accelerator components within the vacuum chamber. The improved bremsstrahlung shielding analysis is compared with pin diode and thermoluminescent dosimetry measurements obtained during the first four months of accelerator testing.
