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.

Take steps on SNF and HLW disposal
Matt Bowen
With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.
In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

This paper presents considerations on basic requirements of fuelling, plasma exhaust and wall conditioning in ITER-EDA. In ITER-EDA, typical machine parameters are 1.5 GW of a fusion power and 1000 sec of a DT burn duration. Fuelling system consists of gas- and pellet injection systems. Maximum DT fuelling rate is 100 Pam3/s (pellet) to 500 Pam3/s (gas). Impurity gas(e.g. Ne, Ar) will be also injected to control divertor radiation loss. In plasma exhaust, designed value of total neutral pressure at inlet of pumping duct is 0.1 Pa to 10 Pa. Total net pumping speed of cryogenic primary pumps is about 300 m3/sec. In maximum, 90% of the regenerated fuel gases (H, D, T) from the primary cryopump will be directly back into the plasma. In wall conditioning, glow discharge cleaning (GDC) and electron cyclotron resonance discharge cleaning (ECRDC) are considered.
