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
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.

General Kenneth Nichols and the Manhattan Project
Nichols
The Oak Ridger has published the latest in a series of articles about General Kenneth D. Nichols, the Manhattan Project, and the 1954 Atomic Energy Act. The series has been produced by Nichols’ grandniece Barbara Rogers Scollin and Oak Ridge (Tenn.) city historian David Ray Smith. Gen. Nichols (1907–2000) was the district engineer for the Manhattan Engineer District during the Manhattan Project.
As Smith and Scollin explain, Nichols “had supervision of the research and development connected with, and the design, construction, and operation of, all plants required to produce plutonium-239 and uranium-235, including the construction of the towns of Oak Ridge, Tennessee, and Richland, Washington. The responsibility of his position was massive as he oversaw a workforce of both military and civilian personnel of approximately 125,000; his Oak Ridge office became the center of the wartime atomic energy’s activities.”

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.
