SHIELDED ELECTROMAGNETIC PUMPS FOR NUCLEAR REACTORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240047089 titled 'SHIELDED ELECTROMAGNETIC PUMPS FOR NUCLEAR REACTORS
Simplified Explanation
The abstract describes an electromagnetic pump (EMP) for a liquid metal-cooled nuclear reactor. The EMP consists of a pump casing, inner and outer flow ducts, and induction coils. The flow annulus is defined by the concentric inner and outer flow ducts, extending coaxially with the longitudinal axis of the EMP. The induction coils control the flow of liquid metal coolant through the flow annulus based on electrical power received from the power supply. The inner or outer flow duct includes a gamma shielding material to block gamma rays from entering the interior of the EMP. The pump casing includes a neutron absorber material to absorb neutrons entering from the exterior of the EMP. Additionally, a neutron moderator material on the outer surface of the pump casing moderates neutrons to be absorbed by the neutron absorber material.

Original Abstract Submitted
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.
