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.

The fabrication and experimental research of a GaN-Positive-Intrinsic-Negative (GaN-PIN) betavoltaic nuclear battery driven by an 63Ni radioisotope source and an SiC-Schottky betavoltaic nuclear battery driven by an 147Pm radioisotope source are introduced. The self-absorption effects of radioisotope sources (63Ni, 147Pm) are explored and analyzed by Monte Carlo simulation. The SiC-Schottky and GaN-PIN betavoltaic cells were fabricated, where the GaN-PIN devices include different areas, absorption layer thicknesses, and electrode structures. And the measured I–V results show that the power density of the GaN-PIN nuclear battery can exceed 4.3 nW/cm2, the open-circuit voltage can reach 1.25 V, and the energy conversion efficiency can reach 2.3%. And for the SiC-Schottky betavoltaic battery, the maximum output power and energy conversion efficiency are 0.67 pW/cm2 and 0.024%, respectively.
