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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

The Z-pinch driven fusion reactor will require extremely high current pulses to generate sufficient x-ray flux for the fusion target implosion. The fusion target is coupled to the pulsed power system through a recyclable transmission line (RTL) that is presently envisioned made of carbon steel. The energy released by the fusion pulse is absorbed by liquid flibe (Li2BeF4) coolant and by the RTL material which is partially vaporized and ionized. The objective of this paper is to characterize the recombination of vaporized metal halides in the presence of ferritic steel in a plasma with parameters similar to those expected in the Z-IFE chamber (plasma density < 2 × 1018 cm-3, Te < 40000 K). Using a substitute eutectic salt (Na2MgCl4) instead of flibe, we find experimentally that the three-body recombination rate of iron with chlorine is larger than that of sodium with chlorine. The measured recombination rates are compared to equilibrium recombination rates calculated at lower temperature (5000 K). The results suggest that an effective scheme for the removal of ferritic fluorite from the liquid flibe coolant may be needed in a Z-IFE reactor in addition to the mechanical separation of carbon steel RTL material required for recycling.
