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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Improvements incorporated into MCNP variance reduction methodology and code releases since 2000 are discussed. Some of the improvements are modifications or generalizations of older techniques, and some are entirely new. In particular, pulse-height-tally variance reduction is now possible in MCNP, and the dxtran technique has been generalized to allow an arbitrary nesting of dxtran spheres. A new precollision, next-event estimator is discussed along with flux-at-a-point image tallies. Additionally, the event log analyzer is a tool designed to help the user understand what causes the variance in the user's particular MCNP calculation.
