Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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 procedure described in the U.S. Atomic Energy Commission Regulatory Guide 4.3, which is intended to keep 131I levels in milk “as low as practicable, ” does not properly account for all sources of analytical error that can occur in a low-level radiochemical procedure. Inaccurate chemical recovery factors due to large amounts of stable iodine in milk and incomplete evaluation of detector background fluctuations are the sources of largest error. Significant errors are also contributed in incorrect application of factors for protein-bound iodine and counting efficiency. Ambient levels of 131I contribute to difficulties in evaluating the local impact of any reactor. Use of a beta/gamma coincidence system for counting 131I, measurement of the stable iodine in milk samples and collection of control samples remote from any site are among the recommendations provided to ensure compliance with the Regulatory Guides.
