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.

DOE opens pilot program to authorize test reactors outside national labs
Details of the plan to test new reactor concepts under the Department of Energy’s authority but outside national laboratory boundaries—first outlined in one of the four executive orders on nuclear energy released on May 23—were just released in a request for applications issued by the DOE.

The initial tritium supply for starting up FDS-II was done by using the Tritium Analysis Software (TAS) developed by FDS Team. The results showed that the initial tritium supply for startup was strongly dependent on the tritium burn-up fraction in plasma and mean residence time of tritium in the plasma exhaust processing system. Considering the sensitive analysis and other advanced designs, the tritium burn-up fraction in plasma was selected to be 0.1 for FDS-II. The minimum initial tritium supply for startup was ~4.2kg. Considering the potential malfunction in the fuel cycle system and assuming the reactor ran continuously before solving the malfunction, it was reasonable to keep the initial tritium supply for FDS-II as ~8.9kg.
