Reactivity booster-quencher, automatic power modules separator, and related methods thereof

A nuclear power reactor comprising:

• a support frame;
• a plurality of power modules movably connected to the support frame through a plurality of movement controllers, each of the plurality of power modules comprising a nuclear fuel and a power conversion system configured to convert heat generated from the nuclear fuel to electricity, the nuclear fuels of the plurality of power modules collectively forming a reactor core;
• a sleeve disposed between the plurality of power modules, the sleeve being structurally connected to the support frame;
• a reactivity booster movably disposed in the sleeve and movable along the sleeve between an end portion and a central portion of the sleeve, the reactivity booster being adapted to provide a positive nuclear reactivity to the reactor core;
• and
• a plurality of module separators each connected to the sleeve and one of the plurality of power modules and extendable to move the one of the plurality of power modules away from the sleeve.
