A plasma interaction simulator is presented. The simulator magnetically induces multiple distinct flows of plasma within a physical plasma vessel. The plasma flows collide with each other at flow interaction boundaries where discontinuities arising due to differences between the flows give rise to interactions. Sensors can be incorporated into the plasma simulator to observe and collect data about the plasma flow interactions.

A nuclear reactor is configured with an intermediate coolant loop for transferring thermal energy from the reactor core for a useful purpose. The intermediate coolant loop includes a bypass flowpath with an air heat exchanger for dumping reactor heat during startup and/or shutdown. A fluidic diode along the bypass flowpath asymmetrically restricts flow across the bypass flowpath, inhibiting flow in a first flow direction during a full power operating condition and allowing a relatively uninhibited flow in a second direction during a startup and/or shut down low power operating condition.

A molten metal transfer pump in which a spiral flow channel is formed by a cylindrical body and a spiral body received in the cylindrical body while being fixed and which allows molten metal to swirl in the spiral flow channel by using Lorentz force generated by a current that flows in a longitudinal direction in molten metal in the cylindrical body and a lateral magnetic field that is generated by a permanent magnet provided on the outer periphery of the cylindrical body.
