Getter trap for removing hydrogen and oxygen from a liquid metal

A liquid metal cooled nuclear reactor system is described comprising: a primary coolant loop including a primary liquid metal coolant, a liquid metal nuclear reactor and a first heat exchanger; a secondary coolant loop including a secondary liquid metal coolant, and first heat exchanger and a second heat exchanger; a third coolant loop including a water coolant, the second heat exchanger and a steam driven device wherein heat from the secondary liquid metal coolant of the secondary liquid metal coolant loop is transferred to the water coolant through the second heat exchanger, and the water coolant flow through the second heat exchanger, the steam driven device and back to the second heat exchanger; a getter trap, disposed in at least one of the primary and the secondary coolant loops, being capable of removing hydrogen and oxygen from the liquid metal flowing in the loops and comprising: an elongated, closed housing having an inlet at one end thereof and an outlet at the other end; a getter material randomly disposed within the housing, the getter material comprising a zirconium-containing substrate of hollow, tubular sections having a coating thereon of a gettering alloy of zirconium, vanadium, and iron
