In at least one embodiment, the liquid circulation system comprises a rotor located within a tank, a stator having a plurality of coils outside the tank, and an exterior tank wall that is non-magnetic and that is located next to the rotor and between the rotor and the stator,
wherein an axis (R) of rotation of the rotor is in parallel with the exterior tank wall, the coils of the stator are arranged along the axis (R) of rotation of the rotor so that the rotor is configured to be rotated by the stator in a touchless manner through the exterior tank wall by means of a varying electromagnetic field driven by the stator to circulate a liquid within the tank.

An electromagnetic pump (EMP) for a liquid metal-cooled nuclear reactor includes a pump casing, concentric inner and outer flow ducts collectively defining a flow annulus extending coaxially with a longitudinal axis of the EMP, and induction coils configured to control the flow of liquid metal coolant through the flow annulus based on electrical power received from the power supply. At least one of the inner flow duct or the outer flow duct includes a gamma shielding material configured to block gamma rays from entering an interior of the EMP from the flow annulus. The pump casing may include a neutron absorber material configured to absorb neutrons entering the pump casing from an exterior of the EMP. The EMP may include a neutron moderator material on an outer surface of the pump casing and configured to moderate neutrons entering the pump casing to be absorbed by the neutron absorber material.

A nuclear reactor is designed to couple the load path of control elements with the reactor core, thus reducing opportunity for differential movement between the control elements and the reactor core. A core barrel can be fabricated in a manufacturing facility to include the reactor core, control element supports, and control element drive system. The core barrel can be mounted to a reactor vessel head. Movement, such as through seismic forces, transmits an equal direction and magnitude to the control elements and the reactor core, thus inhibiting the opportunity for differential movement.
