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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

An extremely simple iterative procedure is described for performing group-diffusion calculations in two and three dimensions No proofs have been found to guarantee its convergence, but successful experience with a wide variety of problems, some realistic, others with specially introduced difficulties, shows the method to be rapid and reliable. Three large computer programs have been devised embodying the principle: EQUIPOISE-3, TWENTY GRAND, and WHIRLAWAY. The first two are two-dimensional programs, while the third is three-dimensional. If desired, the programs can be used to compute adjoint fluxes and those integrals necessary for perturbation calculations automatically. Possible further applications of the method are suggested.
