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.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Every few years, maintenance will be required to replace the plasma facing components of any fusion power plant. To come up with a realistic maintenance scheme, an accurate method of evaluating the biological dose rate is needed. In some studies, the simple and quick approach of the contact dose rate for a specific component was used to estimate the biological dose rate. This method doesn't take radiation from nearby components into account and the accuracy of its methodology is questionable. The more accurate multi-step method, which involves transporting the delayed gammas from induced activation in the forward or adjoint mode, is able to take radiation from all surrounding components into account. In this report, the biological dose rate was evaluated with the adjoint method at selected radial locations of ARIES-CS, and then compared to the contact dose rate of the nearest component to determine the accuracy of the contact dose method. Our results indicate that the approximate contact dose rate could be off by an order of magnitude.
