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.

Bipartisan nuclear waste bill introduced in U.S. House
U.S. representatives Mike Levin (D., Calif.) and August Pfluger (R., Texas) have introduced the bipartisan Nuclear Waste Administration Act of 2024, which would establish an independent agency to manage the country’s nuclear waste.
In addition to establishing a new, single-purpose administration to manage the back end of the nuclear fuel cycle, the bill would direct a consent-based siting process for nuclear waste facilities and ensure reliable funding for managing nuclear waste by providing access to the Nuclear Waste Fund. According to Pfluger and Levin, the bill’s provisions are in line with recommendations from the Blue Ribbon Commission on America’s Nuclear Future.

The development of the Oyster Creek RETRAN licensing model is presented. A three-step program was followed, namely:Step 1. Model benchmark against start-up tests: The objective here was to assure model stability and to qualify different segments of the model against plant data. A best-estimate model was thus established at this stage. Nine start-up tests were used.Step 2. Assurance that the model has built-in conservatism with respect to the reload transients it is designed to analyze. Here, a sensitivity study was carried out on a number of parameters for the limiting reload transient for Oyster Creek [turbine trip without bypass (TTWOB)]. The impact on the critical power ratio was used as the primary measure. Results from this study were used in establishing a conservative set of parameters, an uncertainty margin, and a proper choice of code options. The implementation of these results established the licensing model.Step 3. Testing the licensing model response against vendor’s analyses for typical reload transients, namely, TTWOB, main steam isolation valve closure without scram, and feedwater controller failure in maximum demand. This methodology has been submitted for U.S. Nuclear Regulatory Commission approval.
