Targetry coupled separation refers to enhancing the production of a predetermined radiation product through the selection of a target (including selection of the target material and the material's physical structure) and separation chemistry in order to optimize the recovery of the predetermined radiation product. This disclosure describes systems and methods for creating (through irradiation) and removing one or more desired radioisotopes from a target and further describes systems and methods that allow the same target to undergo multiple irradiations and separation operations without damage to the target. In contrast with the prior art that requires complete dissolution or destruction of a target before recovery of any irradiation products, the repeated reuse of the same physical target allowed by targetry coupled separation represents a significant increase in efficiency and decrease in cost over the prior art.

A moveable sludge lance (76) said moveable sludge lance having duel lance heads (77, 79) passed through handholes (62) in the side of a nuclear steam generator and into a central tube lane (60) having a central stay rod (61) which cleans with high pressure fluid through the row 1 tubes (85) in the tube lane, where the distance (200) between the dual lance heads (77, 79) is wide enough to allow the dual lance heads to extend beyond the central stay rod (61).

A method of using transuranic elements to create nanofuel, including: receiving, converting, and mixing the transuranic elements with a moderator to obtain nanofuel. A method of operating a nanofuel engine loaded with nanofuel in spark or compression ignition mode. A method of cycling a nanofuel engine, including compressing nanofuel; igniting nanofuel; capturing energy released in nanofuel, which is also the working fluid; and using the working fluid to perform mechanical work or generate heat.

A nanofuel engine including an inventive nanofuel internal engine, whereby nuclear energy is released in the working fluid and directly converted into useful work, with the qualities of an economical advanced small modular gaseous pulsed thermal reactor. Scientific feasibility is established by studying the behavior of nuclear fuels in configurations designed to support a fission chain reaction. Nanofuel is defined as nuclear fuel suitable for use in an internal engine, comprised of six essential ingredients, and can be created from clean fuel or from the transuranic elements found in light-water reactor spent nuclear fuel in a proliferation resistant manner. Three essential ingredients ensure the nanofuel is inherently stable, due to a negative temperature coefficient of reactivity. Reciprocating and Wankel (rotary) internal engine configurations, which operate in an Otto cycle, are adapted to support a fission chain reaction. Dynamic engine cores experience a decrease in criticality as the engine piston or rotor moves away from the top dead center position. In this inherent safety feature, the increase in engine core volume decreases the nanofuel density and increases the neutron leakage. Technological feasibility is demonstrated by examining potential engineering limitations. The nanofuel internal engine can be operated in two modes: spark-ignition with an external neutron source such as a fusion neutron generator; and compression-ignition with an internal neutron source. The structural integrity can be maintained using standard internal combustion engine design and operation practices. The fuel system can be operated in a closed thermodynamic cycle, which allows for complete fuel utilization, continuous refueling, and easy fission product extraction. Nanofuel engine power plant configurations offer favorable economic, safety, and waste management attributes when compared to existing power generation technology. The initial (first-of-a-kind) overnight capital cost is approximately $400 per kilowatt-electric. Obvious safety features include an underground installation, autonomous operation, and an ultra-low nuclear material inventory.
