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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

An explanation is given for the anomalous branching ratio in solids based on Boson-cooperative removal of the 4He* energy prior to decay by two-body fission. Facilitated by isospin restrictions that limit conventional pathways, the excess heat is driven by the reconfiguration to the more tightly bound 4He ground state. A temperature rise occurs as well-mixed acoustical and optical phonons are unable to carry off all the local momentum and excess energy of the reactions. Four-vector analysis indicates conservation of energy, which suggests the use of a fusion quantum of energy delivered to the lattice's phonon cloud: a phuson. Special relativistic considerations indicate that the phonon cloud subtends ∼450 to 800 unit cells and can couple with de-excitation times >0.1 fs. Thus, commensurate levels of neutrons and gammas are not required because of unique isospin and energy restrictions that facilitate the alternate Bose-cooperative pathway leading from the excited state.
