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.

Zachry Nuclear is a full service engineering firm that has been providing engineering, design, software development, and operations & maintenance (O&M) support services for electric utilities, advanced reactor designers, research organizations, regulators, Architect/Engineers, fuel vendors, and government energy agencies worldwide for over 45 years. Zachry Nuclear, and predecessors, Proto-Power Corporation (PPC), Numerical Applications, Inc. (NAI) and Computer Simulation & Analysis, Inc. (CSA), are internationally recognized for our expertise in thermal hydraulics analysis, radiological analysis, safety analysis and software development. We develop several industry standard analysis codes such as GOTHIC (coarse grid CFD), RETRAN-3D (system thermal-hydraulic and 3D neutron kinetics), VIPRE (subchannel), PROTO-FLO (piping analysis and design), PROTO-HX (heat exchanger performance), RADTRAD-NAI (dose and radiological consequences) and also develop custom software solutions. We specialize in applying these and other tools to provide significant cost savings for our clients through efficiency improvements, margin recapture, operations flexibility, and effective designs by developing innovative engineering solutions through automation, optimization, advanced modeling and simulation and machine learning methods. Our clients include existing plants and advanced reactor vendors supporting many of the SMR, non-LWR and microreactors currently being designed and developed both in the US and internationally.
