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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

The National Spherical Torus Experiment Upgrade (NSTX-U) is currently under construction at Princeton Plasma Physics Laboratory (PPPL) It is scheduled to start operations early in 2015. Upgrade designs were analyzed and qualified prior to the beginning of construction, but many issues arose during manufacture and assembly that required adjustments in design and analysis of components. Some designs relied on testing that occurred after final design when the actual material and processes were selected by vendors or in-house shops. Design of some components, like the bus bars, was deferred until field run interferences could be identified. Some components used materials that did not meet original specifications. New materials or processes had to be found and components sometimes needed requalification. PPPL responsible or “Cognizant Engineers” (COG’s) and analysts worked closely to work out resolution of issues and perform redesign and reanalysis. Revisions to calculations were prepared and filed. Some significant items addressed during the construction period (or Title III in DOE parlance) are selected for more detailed discussion.
