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.
Mathematics & Computation
Division members promote the advancement of mathematical and computational methods for solving problems arising in all disciplines encompassed by the Society. They place particular emphasis on numerical techniques for efficient computer applications to aid in the dissemination, integration, and proper use of computer codes, including preparation of computational benchmark and development of standards for computing practices, and to encourage the development on new computer codes and broaden their use.

A day in the life of the nuclear community
The November issue of Nuclear News is focused on the individuals who make up our nuclear community.
We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.
In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.
The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

In facilities containing tritium, all process equipment is contained in inerted gloveboxes operating at slightly negative pressure relative to the process rooms. The gloveboxes have recirculation systems which include a stripper system. The glovebox stripper systems capture tritium from the glovebox atmosphere to minimize facility emissions with the possibility of recovering the tritium.
Hydrogen isotopes released into the gloveboxes are converted to oxide form and removed from the glovebox atmosphere by the glovebox stripper systems – the intended function of these systems. Protiated water (and oxygen) enters the glovebox system in various ways. All water in the gloveboxes is ultimately removed by the stripper system molecular sieve beds which are then processed or disposed of as waste. The water and oxygen enter the glovebox in locations both internal and external to the gloveboxes. The majority of oxygen and water originates external to the gloveboxes in current facility operations.
This study evaluated approaches for water source reduction i.e. reducing the amount of water entering the gloveboxes. The second approach explored options to segregate or prevent the mixing of protiated water in the glovebox with the tritiated water formed as part of the tritium oxidation and capture process used to reduce facility emissions.
