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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Standard on fixed neutron absorbers in nuclear facilities outside reactors just issued (ANS-8.21)
ANSI/ANS-8.21-2023, Use of Fixed Neutron Absorbers in Nuclear Facilities Outside Reactors, has just been issued by the American Nuclear Society Standards Committee. The standard was approved by the American National Standards Institute (ANSI) on June 20, 2023, as a revision and consolidation of ANS-8.21-1995 (R2019) (withdrawn) (same title) and ANS-8.5-1996 (R2022) (withdrawn), Use of Borosilicate-Glass Raschig Rings as a Neutron Absorber in Solutions of Fissile Material. ANSI/ANS-8.21-2023 provides guidance for the use of neutron absorbers, including Raschig rings, as an integral part of nuclear facilities equipment, fissile material, or fuel components outside reactors, where such absorbers are credited to provide criticality safety control.

The industry many times makes it difficult for suppliers to meet our requirements in the most cost effective way for both the utility and the supplier. When different utilities (and sometimes different plants within that utility) request items, they have widely varying descriptions of what they desire. This goes beyond the technical requirements being imposed and includes our terms of conditions, invoicing instructions, and procurement levels. It also will include effective interfacing between the appropriate levels in each organization, minimizing late night call-outs, things utilities can do to reduce cost, and things utilities do that hurt the process. This session will be a workshop where various suppliers can brainstorm with their utility counterparts on ways in which changes can be made that will assist both sides in reducing costs and decreasing number of non-conformances. Goal will be recommendations for the industry in a number of areas that will help alleviate these impediments.
