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.
Fuel Cycle & Waste Management
Devoted to all aspects of the nuclear fuel cycle including waste management, worldwide. Division specific areas of interest and involvement include uranium conversion and enrichment; fuel fabrication, management (in-core and ex-core) and recycle; transportation; safeguards; high-level, low-level and mixed waste management and disposal; public policy and program management; decontamination and decommissioning environmental restoration; and excess weapons materials disposition.

NRC’s Inspector General issues report
Overall findings of a survey of Nuclear Regulatory Commission personnel indicate that while the NRC maintains a few strengths compared to external benchmarks, results have declined since 2015 in a number of areas, according to a recent report from the NRC’s Office of the Inspector General (OIG).
The survey was conducted in February 2020 by Willis Towers Watson, a global risk-management, insurance brokerage, and advisory firm that has partnered with the OIG for more than 20 years to assess the NRC’s safety culture and climate, as well as other aspects of employee experience.

A pilot rig for a preparative gas chromatograph is described. In order to increase the volume of the samples to be separated different separation columns were investigated. The pilot plant is designed as to operate also with two columns at the same time. To recover the separated H isotopes the pilot rig was equipped with three uranium getters which can be automatically switched to the separation columns by electropneumatic valves. These valves are actuated in response to a detector signal. The maximum sample volume achieved with one separation column is 600 ml (STP) of a three-component mixture (H2, HD and D2) with a purity of 98.5 - 98.7% and even 1000 ml (same mixture) with a 91% purity with respect to the components H2/HD.
