• Initial coatings improve the microstructure of surrogate fuel elements. coating thickness is crucial in tuning microstructure. Potential for elements with greater than 60 vol.% fissile exists. Higher fractions would result improved efficiency and decreased weight. Nuclear thermal propulsion (NTP), which may utilize cermet fuels, shows promise improving feasibility long-distance space travel. ...

The feasibility of using various uranium-free fuels for plutonium incineration in present light water reactors is investigated. Two major categories of inert matrix fuels are studied: composite ceramic fuel particles dispersed in another ceramic matrix (CERCER) and ceramic fuel particles dispersed into a metallic matrix (CERMET). In the category of CERCER, the current world wide research effort...

Reproduced by the permission of ECS – The Electrochemical Society leakages to fuel system will retain the anode in oxidized state. Moreover, some performance loss was measured when the stack was heated to 400 C before fuel supply was started. Therefore, it is recommended that the supply of hydrogen-rich reducing gas is started already below 350 C, or as low temperature as possible, to prevent o...
