But I kind of took that into account when I plugged the power density of 200 W/g for Pd into the spreadsheet. For bulk Pd, ~50 W/g may be close to the limit. I plugged in 200 W, admittedly arbitrarily, because I figure the Pd could be in small spots that are quickly cooled by the surrounding material. I met a fellow who was trying to put Pd spots on synthetic diamond. Diamond is the best heat sink, he claimed. For a uranium oxide fuel pellet, 25 W/g is the limit, I think. The zirconium tubes in pressurized water cannot stand up to much higher temperatures. - Jed
