In a combustion motor the high temperature is generated inside the combustion
gases and the distributed into a rather large metal surface. A lot of heat is
blowed out as combustion product.
In the ecat, however the source of temperature is inside the metal -inside the
nicke core and lead shielding- and then it is distributed into the water. As
soon as the water boils, the thermal resistance will increase dramatically and
this should generate a very high temperature gradient @ 100kW that leads to
metal melting and steam explosion. This could also lead to hydrogen explosions
like in Fukushima, because glowing hot metal + steam gives free hydrogen and
metaloxide.
