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.

The Super-FRS is designed as a versatile partially superconducting fragment separator for the planned international Facility for Antiprotons and Ion Research. It will be able to separate all kinds of nuclear projectile fragments of primary heavy-ion beams including uranium with energies of up to 1.5 GeV/u and intensities of up to 1012 particles/s. The primary beam power of up to 50 kW has to be dumped in six shaped beam catchers in accordance with the ion optical setting of the separator in order not to enter the main separator, which will have accordingly weaker shielding. A key issue for such a high-power facility is the activation of several components and thus their access by maintenance personnel. Both the prompt and the residual dose due to activation are calculated by means of the Monte Carlo particle transport code FLUKA.The biological shielding in the target area will be realized by massive iron blocks (thickness [approximate] 2 m) around the beam tube and the magnets. This will be surrounded by up to 6 m of concrete in order to reduce the dose rates below the design value of 0.5 Sv/h, which is in agreement with the German radiation protection ordinance for public access. A dedicated maintenance channel is foreseen in which the residual dose rates are tolerable for short time access after a certain cooling time.
