1. A passive nuclear reactor control device, comprising:
a sealed chamber comprising:
a reservoir;
a tube in fluid communication with the reservoir,
a molten salt within the sealed chamber, the molten salt being a eutectic mixture of:
a monovalent metal halide, and
a fluoride or chloride of:
one or more lanthanides and/or
hafnium;
a gas within the sealed chamber which does not react with the molten salt.
