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.

The hardness distribution and the effect of post welding heat treatment (PWHT) at 600°C and 1000°C for 1 h and aging heat treatment at 600°C for 1000 h in the dissimilar-material electron beam weld (EBW) joint with pure-V and SUS316L austenitic stainless steel were investigated. The electron beam was positioned just on the butt joint (EB00), shifted by 0.2 mm (EB02) and 0.4 mm (EB04) on the pure-V side. The EBW joint was distinguished into the base metal of V (V-BM), weld metal (WM), interlayer at the edge of the WM of SUS316L side (IL) and base metal of SUS316L (SUS316L-BM). The IL was observed only in the EB02 and EB04 joints. The formation of macro-pore was observed in the EB04 joint. Much higher hardness was observed at the WM and IL of the as-welded EB00 and EB02 joints than the other regions of them. The hardness change in the WM was relatively small due to the PWHT at 600°C up to 1 h, whereas significant increment was observed due to the PWHT at 1000°C for 1 h regardless of the EB position. The hardness of the IL after the PWHT at 600°C was almost twice higher than that of the as-welded one, which showed slightly further increment at 1000°C. Rapid increment of the hardness due to the aging at 600°C for 1–10 h and slightly further increment of it due to the aging for 100–500 h occurred in the WM of the EB00 joint.
