“…It has several atypical properties when compared to standard metals [1,2]. Plutonium has a very low melt temperature (913 K) and contracts while melting, a property shared with water and some semimetals, has poor electrical and thermal conduction characteristics, but has good elastic compressibility.…”

We have calculated the viscosity and self-diffusion coefficients of plutonium in the liquid phase using quantum molecular dynamics (QMD) and in the dense-plasma phase using orbital-free molecular dynamics (OFMD), as well as in the intermediate warm dense matter regime with both methods. Our liquid metal results for viscosity are about 40% lower than measured experimentally, whereas a previous calculation using an empirical interatomic potential (modified embedded atom [LANL publication number: LA-UR-10-07728]

“…While most noted in its role in nuclear explosions, plutonium has many applications, e.g. supplying the heating element in radioisotope thermoelectric generators used in remote sensing stations and deep-space craft such as Cassini and forming a principal component in closed fuel cycles for fast nuclear reactors as part of advanced energy initiatives [1].…”

“…The items to be studied are as follows: (1) particle size, (2) sample thickness, (3) presence of contaminated materials, (4) sample temperature, and (5) the response of the TOF spectrometer [3,17]. Some experiments has been performed at GELINA [18][19][20][21]. A resonance shape analysis code, REFIT [22], has been adopted for the data analysis.…”

“…The reason for adopting the TRU-Zr alloy fuel is to use a simpler fuel fabrication method, that is, injection casting, in contrast to a TRU-Zr particle fuel in a zirconium metal matrix. Then, the zirconium content in TRU-Zr alloy was assumed to be limited below 35 wt% to keep the melting point of the TRU-Zr alloy below 1,200 C to prevent Am vaporization during injection casting [19]. The fuel pins and the BeO pins were separately located in the fuel subassemblies ( Fig.…”

“…A variety of Pu-based alloys have been tested as fuels for fast reactors in the United States and Europe with various degrees of success [2]. The phase diagrams are important for understanding the complex processes that may take place in a nuclear energy plant and helping us guide the selection and development of new metallic fuels.…”
