ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

A fusion reactor blanket having a large tritium breeding ratio (TBR) is proposed. The blanket has a front breeder zone on the plasma side near its multiplier. A suitable zone thickness is 1 cm when 6Li enrichment is 50%. Combined with a multiplier composed of only ∼18-cm-thick beryllium, the TBR is maximized at a value over 20% larger than that of a blanket without a front breeder zone. Since the beryllium multiplier is supposed to include 5% of SUS as structural material in addition to cooling channels, a 12-cm-thick multiplier gives the maximum TBR as >1.4 for the blanket with the front breeder zone.
