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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

The laser driver for the National Ignition Facility will be a departure from previous inertial confinement fusion laser architecture of a master-oscillator single-pass power-amplifier (MOPA) design. The laser will use multi-segment Nd: Glass amplifiers in a multipass cavity arrangement, which can be assembled into compact and cost-effective arrays to deliver the required multi-megajoule energy to target. A single beam physics prototype, the Beamlet, has been in operation for over two years and has demonstrated the feasibility of this architecture. We present a short review of Beamlet's performance and limitations based on beam quality both at its fundamental and frequency converted wavelengths of 1.053 and 0.351 μm.
