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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

The plutonium concentrations in mixed-oxide fuel rods containing distinct sizes of particulate plutonium oxide have been determined using high resolution gamma-ray spectrometry. The fuel rod enrichments were in the range 2 to 2.5 wt% in natural UO2. Individual rod enrichments were determined to within ±0.1 wt% by comparison with a known standard. Differences in plutonium iso-topic composition were discemable also, in addition to the differences in plutonium enrichment. The technique provides an inexpensive nondestructive method of determining in situ plutonium composition and content of assembled fuel rods, for purposes of quality assurance and accountability control.
