Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.”

A digital computer approach for predicting the dynamic response of surge tanks is presented. The applications of different models are presented for analyzing the primary pressure transients of CANDU reactors. Conservation equations for deformable control volume have been employed to describe the flow inside both of the closed distinct regions (phases). In this model, the upper region can be either in the superheated state or two-phase saturated state. The lower region can be in the subcooled state or two-phase saturated state. Energy and mass transfer processes occurring inside the surge tanks have been investigated and determined under various operating conditions. These processes are spray condensation, wall condensation, vapor flashing, heat transfer at interface, and heat transfer from heaters. Numerical results showed that this model favorably predicted the pressurizer pressure when compared with those calculated by adiabatic and equilibrium models employed in the SOPHT code and with data obtained from the Gentilly-2 site and Bruce NGS-A.
