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.

The equilibrium phase diagram of the condensed system NaF/BeF2/ThF4 is presented. Liquid/solid phase transitions were found in the temperature range from ∼300 to 1100 C. The phase diagram of the system is based on data obtained from thermal analysis and thermal-gradient-quenching experiments; phase identifications were made employing the polarizing light microscope and the x-ray diffractometer. Thirteen crystalline phases are precipitated as primary phases from molten NaF/BeF2/ThF4 solutions: 4NaF-ThF4, 7NaF·2ThF4, 2NaF·ThF4, 3NaF·2ThF4, α- and β -NaF·ThF4, NaF-2ThF4, 2NaF·BeF2, NaF·BeF2, NaF·BeF2, ·3ThF4, NaF, BeF2, and ThF4 solid solution. The character, location, and temperature of the fourteen invariant and singular points in the system were established. The ternary system is comprised of two subsystems, NaF/2NaF·ThF4/2NaF·BeF2 and 2NaF·ThF4/ThF4/BeF2/2NaF·BeF2, separated by the quasibinary section, 2NaF·BeF2/2NaF·ThF4. The lowest liquidus temperatures in the respective subsystems were found at the eutectics, 72NaF/22BeF2/6ThF4 (mole %), m.p. 509 C, and at 55NaF/43BeF2/2ThF4 (mole %), m.p. 320 C.
