Energy deposition in NSRR silicide fuels

The energy deposition in NSRR U3Si2-Al fuel plates has been evaluated in this report. It was assumed that one test plate was irradiated transiently in NSRR experiment hole. The uranium density in the fuel meet ranged between 2.15 gU/cm3 and 5.01 gU/cm3. The length of fuel plate ranged between 10.0 cm and 20.0 cm. The average energy deposition in the fuel plate which uranium density is 5.01 gU/cm3 and fuel length is 15.0 cm, is 548.6 cal/g/100 MW/sec. The melting point of U3Si2 is 1938 K. The test plate is melt at the energy deposition which is 225.4 cal/g (density 12.2 g), so the test plate will be melt by NSRR experiment. According to increase in uranium density, the average energy deposition in unit volume increase, but that in unit mass dicrease. The energy deposition distribution is rose up at the top and bottom of the test plate, and it is flat at the center of it. (author)
