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.

A detector using a gas-flow technique to measure the in-core fast neutron flux was designed, developed, and experimentally tested. Based on the 9Be(n,α)6He reaction of neutrons with beryllium, the method uses a flowing gas (helium) to bring the 6He beta emitter to an ex-vessel beta detector to achieve measurements independent of the gamma irradiation of the in-vessel neutron detector. In tests at the TRIGA reactor of Washington State University, the system demonstrated a fast neutron sensitivity of 3.7 × 10−10 counts/sec per n/(cm2 sec). Thus, using appropriate counting techniques, the technique could have an operational range of 109 to 1016n/(cm2 sec).
