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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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 compatibility of tungsten, W-0.9wt%Cb, W-10wt%Re, W-25wt%Re, TZM (Mo-0.5wt%Ti-0.08 wt%Zr), Mo-50wt%Re, and rhenium in static lithium was determined. Exposures were at 2500, 2800, and 3000°F for periods of 100 and 1000 h. Exposures were conducted in TZM containers for all alloys tested. The results obtained must be viewed in light of the dissimilar capsule employed. The tungsten-base materials were not attacked by lithium after 100- or 1000-h exposure at 2500°F. At 2800°F, all of the tungsten-base materials exhibited varying degrees of surface dissolution and grain-boundary penetration. TZM and Mo-50wt%Re alloys were resistant to attack by lithium at up to 3000°F for 100- and 1000-h exposure. Unalloyed rhenium underwent dissimilar metal interaction while immersed in lithium in TZM test capsules for 1000 h at 2500°F and 100 h at 3000°F. Molybdenum was transferred from the TZM corrosion capsule to the rhenium where alloying occurred.
