Patent number: 11923098Abstract: A customizable thin plate fuel form and reactor core therefor are disclosed. The thin plate fuel will comprise a fuel material embedded within a matrix material, with the entire unit having a coating. The thin plate fuel may be flat or curved and will have flow channels formed within at least the top surface of the fuel plate. The structure of the thin plate fuel will make it easier for coating with Tungsten or any other suitable material that will help contain any byproducts, prevent reactions with the working fluid, and potentially provide structural support to the thin plate fuel.Type: GrantFiled: September 10, 2021Date of Patent: March 5, 2024Assignee: HOWE INDUSTRIES, LLCInventors: Troy M. Howe, Steven D. Howe

Publication number: 20130114775Abstract: A process for producing isotopes by continuously flowing a liquid stream, carrying capsules of target nuclei (NP-237) in solution, through a nuclear reactor (a TRIGA style nuclear reactor). Upon removal from the core of the nuclear reactor and after allowing for the decay of Np-238 to Pu-238, the capsules are emptied and the mixture of elements and isotopes are chemically separated using solvent extraction or ion exchange.Type: ApplicationFiled: August 29, 2012Publication date: May 9, 2013Applicant: UNIVERSITIES SPACE RESEARCH ASSOCIATIONInventors: Steven D. HOWE, Jorge NAVARRO, Douglas CRAWFORD, Terry RING

Publication number: 20030183783Abstract: The invention provides a container for transporting antiprotons including a dewar having an evacuated cavity and a cryogenically cold wall. A plurality of thermally conductive supports are disposed in thermal connection with the cold wall and extend into the cavity. An antiproton trap is mounted on the extending supports within the cavity. A sealable cavity access port selectively provides access to the cavity for selective introduction into and removal from the cavity of the antiprotons. The container is capable of confining and storing antiprotons while they are transported via conventional terrestrial or airborne methods to a location distant from their creation.Type: ApplicationFiled: April 1, 2003Publication date: October 2, 2003Inventors: Gerald A. Smith, Raymond A. Lewis, Steven D. Howe

Patent number: 5236755Abstract: An optical recording element has a recording layer (18) protected by an overcoat layer (20) which is transmissive to laser radiation used for writing pits in the recording layer (18). The thickness of the overcoat layer (20) is selected to be less that the conventional 1/2 wavelength thickness and the recording layer thickness is selected, in conjunction with the overcoat layer thickness in such a way that the minimum value of reflectivity on the reflectivity-v-thickness curve is depressed.Type: GrantFiled: July 26, 1991Date of Patent: August 17, 1993Assignee: Imperial Chemical Industries PLCInventors: Steven D. Howe, Lynn Y. Dorey
