International Classification:

A61F 2/28

US Classification:

623 1611, 606 62

Abstract:

Devices and associated methods are disclosed for treating bone, and particularly bone tissue at the joints. Disclosed are implantable devices that can be used either alone or in combination with this augmentation or hardening material for the repair of bone defects and which are particularly suited for use at the joints, and even more particularly, suited for use at the subchondral bone level.

Michael E. Hanson - Clifton Park NY, US

International Classification:

G21C 3/54

Abstract:

A salt composition for use as a fuel in a nuclear reactor is provided. The salt composition can include carrier salts having mixtures of one or more chloride salts or one or more chloride salts and one or more fluoride salts and fuel salts including one or more chloride salts. The carrier salts can include alkali and/or alkaline earth cations, while the fuel salts can include actinide cations. The salt composition has a lower melting temperature, less corrosive redox properties, and allows proliferation-safe retention of actinides and concurrent removal of some fission products, as compared to other salts employed in molten salt reactors. Optionally, the salt composition can include one or more metal halides for further decreasing the melting point and/or increasing the boiling point of the composition, thereby increasing the range of the liquid phase of the salt composition.

Abstract:

A molten salt reactor comprising a reactor vessel and a molten salt contained within the reactor vessel. There is a corrosion reduction unit configured to process the molten salt to maintain an oxidation reduction ratio, (E(o)/E(r)), in the molten salt at a substantially constant level, wherein E(o) is an element (E) at a higher oxidation state (o) and E(r) is the element (E) at a lower oxidation state (r).
