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.
Meeting Spotlight

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

Thermocouples (TCs) spot welded on a surface, in two-phase flow, may rewet much sooner than the surrounding surface; they even may act as promoters for rewetting. In some loss-of-flow-test experiments, such spot-welded TCs are used to measure the cladding surface temperature of the fuel rods. Tests in the controlled blowdown simulation facility Karlsruhe (COSIMA) were performed using fuel rod simulators with and without such TCs. The cladding surface temperatures measured with the COSIMA pyrometers were compared, and it was concluded that the influence of the TCs cannot be neglected.
