"An auxiliary power source of 250 kW will be needed to start up the plant, bringing the resistive heaters up to temperature."That's a lot of juice, boys and girls.
it can produce up to one megawatt of power in the form of hot water, or low temperature steam
It cannot "melt down" like conventional nuclear reactors. This is because if the temperature inside the reactor cores rise beyond a certain level, the nickel powder will melt, destroying the reaction sites at which the nuclear reactions take place. With the reaction sites destroyed, the reactor cores will no longer function, and all nuclear processes will cease.
Hmm. I wonder what the licensing requirements are for a fusion/nuclear reactor.
Not for a 1 MW plant. It's like getting a 4.5 kW water heater at home (a very typical setup) that requires 1 kW of power whenever you start it up. My tea kettle takes more than 1 kW.
