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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

An exact solution is developed for a plane source of thermal neutrons embedded in an infinite array of absorbing plates. Using methods based on generating functions and the theory of complex variables, we can obtain explicit values for the flux at the plate surfaces and hence at any position within the lattice.The effect on the flux distribution of allowing the plate absorption parameter (Galanin's constant) to be a random variable, uniformly distributed between an upper and lower limit, is calculated. It is found that randomness leads to a reduced rate of decay with distance from the source, in agreement with other theories concerning this problem.
