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?

An inertial electrostatic confinement (IEC) fusion device is possibly used for portable neutron sources. R. L. Hirsh reported that D-D the neutrons of 1.8 × 108 n/s were produced. Recently, the similar amounts of fusion reactions are observed to occur in IEC devices In the most of IEC devices, since gas pressure is so high that the ions lose their energy by the frequent collisions with the neutral gas. The conditions of the high voltage and the low pressure are preferable because the energy of beam ions is kept very high and used for the fusion reaction more efficiently. It, however, is difficult to produce enough amounts of ions through a glow discharge at the low pressure. One of the solutions is to equip the ion source such as a magnetron near the anode. We have made three-dimensional orbit following code to evaluate the life of the ions produced near the anode surface. The code includes atomic collisions with background neutral gas and indicates the optimal positions to equip ion source which gives longer life of accelerated ions.
