IGNITER, FUEL AND REACTOR

摘要

The invention discloses an igniter, a fuel, and a reactor in which the former two can be used in order to achieve a fuel reaction. The igniter arrangement comprises an electromagnetic holder means (101) to hold, in a non-contacting manner, a reactant (104) in the reaction volume of the igniter, a temperature regulating means (102) for controlling the temperature of the reactant (104), and a radiation means (103) for radiating the reactant in order to initiate a reaction in the said reaction volume. The reactor includes an igniter arrangement for initiating a nuclear reaction in a reactant in a reaction volume of the reactor, a feeding means (201) for feeding a nuclear fuel into the said reaction volume, and a heat exchanger arrangement (202) for transmitting heat out of the reaction volume. The invention also discloses an arrangement for controlling a reaction.
