Applicability of Microwave Heating to the Simulation of the LMFBR Meltdown Process

摘要

In the analysis of post accident heat removal (PAHR) following a hypothetical core-disruptive accident (HCDA) in an LMFBR one is faced with the problem of simulating a boiling pool of a fissile fuel, steel mixture. Previous work at Argonne National Laboratory has recommended that a small scale simulation study of melt-through by microwave heating would be useful on the basis of scoping studies which indicate that the internal heating is quite uniform. In the present work, the effects of droplet size, temperature, dielectric properties and wavelength on the absorption efficiency are investigated and the appropriate materials for obtaining near equal volume heating over a range of droplet sizes of 5.0 x 10 exp -4 cm to 10 cm in radius are suggested for a suitable wavelength.
