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.

Reboot: Nuclear needs a success . . . anywhere
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

For pressurized water reactor fuel, to correlate clad failure characterization and localization methods with primary cooling water gamma measurements, it was necessary to define the set of equations describing fission product (FP) generation and transport. Such a technique has been developed by the French Commissariat à l’Energie Atomique (CEA) and Framatome. It required working out the computer code PROFIP.3. The main features of the code are calculations of the FP source term and release mechanisms from the fuel into the coolant through the gap and failed cladding, with mass balance in the coolant. Framatome and CEA experience over past years provided a large data base from which the main characteristics—gaseous FP ratio and release coefficients—have been determined. Localization at the defective elements is based mainly on the 134Cs-to-137Cs ratio during transient periods correlated to burnup. Measurements taken by a sipping test during the refueling periods and comparison with the last three cycles at the Tihange reactor have shown good confirmation of this approach. A large-scale study of FP activity is an on-going joint effort by Framatome and CEA.
