Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Dragonfly, a Pu-fueled drone heading to Titan, gets key NASA approval
Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.
On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

HANARO (High flux Advanced Neutron Application ReactOr) is an open-tank-in-pool-type, multipurpose research reactor. Since the commencement of HANARO operations in 1995, a significant number of experimental facilities have been developed and installed, and continued efforts to develop more facilities are in progress. Owing to a stable operation of the reactor and its rapid utilization, more experimental facilities are being continuously added to satisfy various fields of study and diverse applications. The equipment is classified into a capsule and a fuel test loop (FTL) for the irradiation tests of the nuclear fuels and materials in HANARO. Capsules for the irradiation tests of nuclear fuels in HANARO, under the conditions of its coolant and materials in dry conditions, have been developed. The FTL can conduct an irradiation test of a nuclear fuel under the operating conditions of commercial nuclear power plants. Three test fuel rods can be irradiated in HANARO by using the FTL. Some instrumentation such as thermocouples, linear variable differential transformers, small heaters, fluence monitors, and self-powered neutron detectors are used to perform the irradiation tests by using these irradiation devices. In this paper, the status of HANARO and its irradiation devices including the instrumentations and some results from these instrumentations during irradiation tests are described.
