Abstract: Composition, manufactures, and processes of making and using them, consisting essentially of a neutron absorbent, having a neutron absorption cross section greater than or equal to Boron comprising at least 19.7% of Boron-10 isotope, and a thermal conductor having a thermal conductivity of at least 10% of water thermal conductivity at 100 degrees C. at sea level, combined such that the particles have a density of at least 0.9982 g/mL and not more than 2.0 g/ml. The composition can be located for release responsive to a loss of normal heat sink event and/or a loss of normal coolant event in a quantity sufficient, to palliate the loss of the normal heat sink event and/or the loss of normal coolant event.

Abstract: Composition, manufactures, and methods of making and using them, illustratively a process including the steps of: changing density of a composition including a neutron absorbent, the absorbent having a neutron absorption cross section greater than or equal to Boron comprising at least 19.7% of Boron-10 isotope, and a thermal conductor having a thermal conductivity of at least 10% of coolant thermal conductivity at 100 degrees C. at sea level, combined into the particles that have a density of at least 0.9982 g/mL and not more than 2.

Abstract: A method and system for balancing a rotary member. The system preferably comprises balancer stand, a stator element including and a levitation element. The rotary member is coupled with the levitation element. The rotary member and the levitation element are positioned above the stator element which preferably comprises a superconductor element. The rotary member and levitation element are suspended above the stator element when the superconductor element is activated through field cooling. The rotary member is titled with respect to a direction of gravity such that an imbalanced portion of the rotary member rests at the lowest point of the rotary member. The imbalanced portion is thereby identified and can be corrected.

Abstract: A magnetic bearing apparatus and a method for providing at least one stabilizing force in a magnetic bearing structure with a superconducting magnetic assembly and a magnetic assembly, by providing a superconducting magnetic member in the superconducting magnetic assembly with a plurality of domains and arranging said superconducting magnetic member such that at least one domain has a domain C-axis vector alignment angularly disposed relative to a reference axis of the magnetic member in the magnetic assembly.
