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.

U.S. nuclear capacity factors: Ideal for data centers?
Baseload nuclear generation doesn’t get the respect it deserves, if you ask nuclear operators. But the hyperscale data centers that process our digital lives—like the one right next to the Susquehanna plant in northeastern Pennsylvania—are pushing electricity demand up. Clean, reliable capacity now looks a lot more valuable.

The pool-type experimental facility CIRColazione Eutettico (CIRCE) has been built by ENEA in support to the development of liquid-metal fast reactors. A computational fluid dynamics (CFD) model of the new test section, called the Thermal-hydraulic HElical Tubes Innovative System or THETIS, is being built, and is described along with the pretest numerical results. The pretest study analysis supports the dimensioning of the experimental setup and provides a sound but still not complete basis for the experimental transients. Appropriate thermal boundary conditions for the steady state are implemented. These conditions are found to be not suitable for thermal transients, hence the necessary compliance is analyzed and defined, requiring additional preliminary experimental tests. The main novelty in the refurbishment of the CIRCE is the installation of an innovative helical coil steam generator (HCSG). The realization of its numerical counterpart is challenging; therefore, a specific CFD model of the HCSG has been developed separately from the global model. Its preliminary results are described and discussed.
