System for dissipating fuel egress in fuel supply conduit assemblies

Title: System for dissipating fuel egress in fuel supply conduit assemblies

Abstract

A system for dissipating fuel egress includes a fuel injector and a fuel supply assembly. The fuel supply assembly has a fuel supply line that provides fuel and a purge air conduit arranged co-axially around the fuel supply line, thereby defining an annular channel around the fuel supply line. The fuel injector includes a perimeter body, a fuel injection port associated with the perimeter body, and an internal mixing chamber downstream of the fuel injection port in a direction of fuel flow. The fuel supply line provides fuel to the fuel injection port. The perimeter body of the fuel injector defines a fuel egress passage therethrough, which has an inlet in fluid communication with the annular channel and an outlet in fluid communication with the mixing chamber. A gas turbine combustor having an axial fuel staging (AFS) system with the present fuel egress dissipation system is also provided.

Between-cycle laser system for depressurization and resealing of modified design nuclear fuel assemblies

Patent Bradley, John G [Richland, WA]

A laser beam is used to puncture fuel cladding for release of contained pressurized fission gas from plenum sections or irradiated fuel pins. Exhausted fission gases are collected and trapped for safe disposal. The laser beam, adjusted to welding mode, is subsequently used to reseal the puncture holes. The fuel assembly is returned to additional irradiation or, if at end of reactivity lifetime, is routed to reprocess. The fuel assembly design provides graded cladding lengths, by rows or arrays, such that the cladding of each component fuel element of the assembly is accessible to laser beam reception.

Automated closure system for nuclear reactor fuel assemblies

Patent Christiansen, David W [Kennewick, WA]; Brown, William F [West Richland, WA]

A welder for automated closure of fuel pins by a pulsed magnetic process in which the open end of a length of cladding is positioned within a complementary tube surrounded by a pulsed magnetic welder. Seals are provided at each end of the tube, which can be evacuated or can receive tag gas for direct introduction to the cladding interior. Loading of magnetic rings and end caps is accomplished automatically in conjunction with the welding steps carried out within the tube.

Multiple fuel supply system for an internal combustion engine

Patent Crothers, William T [Sunol, CA]

A multiple fuel supply or an internal combustion engine wherein phase separation of components is deliberately induced. The resulting separation permits the use of a single fuel tank to supply components of either or both phases to the engine. Specifically, phase separation of a gasoline/methanol blend is induced by the addition of a minor amount of water sufficient to guarantee separation into an upper gasoline phase and a lower methanol/water phase. A single fuel tank holds the two-phase liquid with separate fuel pickups and separate level indicators for each phase. Either gasoline or methanol, or both, can be supplied tomore »« less
