20100020915 | METHOD OF RENDERING A RADIOACTIVE AND AQUEOUS HEAT TRANSFER LIQUID IN A NUCLEAR REACTOR TO A REDUCED RADWASTE QUANTITATIVE STATE AND RETURNING THE REMAINING WASTE WATER VOLUMES TO AN ENVIRONMENTAL RELEASE POINT FOR LIQUID EFFLUENTS - Environmentally protective Method of treating an aqueous radioactive fluid (AF) in a nuclear reactor cycle or radwaste system to selectively capture or remove radioactive isotopes in a reduced quantitative package to minimize radwaste generated and revitalize neutron absorption capacity of nuclear reactor coolant by separately carrying away boron constituents, when B | 01-28-2010 |
20100069700 | METHOD AND DEVICE FOR EVAPORATE/REVERSE OSMOSIS CONCENTRATE AND OTHER LIQUID SOLIDIFICATION - A Method and Device for solidification of waste liquids and fluids is disclosed, which is particularly well suited to processing radioactive waste fluids. Set forth is a receiving unit or subassembly for housing solidification agent, and one or more manifold units or subassemblies positioned within the receiving unit for providing waste fluid. The subassemblies operate in relation to each other to provide, position and mix solidification agent or polymer with waste fluid so that a dirt-like polymerized waste product is produced and positioned in the container for removal or later safe shipment or storage. Mathematical relationships, in preferred embodiments or aspects are utilized in determining number and sizing of manifold openings, and pressure of waste to be provided, to meet the requirements of waste fluids to be transported through these openings into the receiving unit. | 03-18-2010 |

20120305458 | HIGH RADIOACTIVITY FILTER - A high radioactivity filter system is disclosed. The invention utilizes within a container substructure a filter employing a combination of specially selected filtration and ion exchange media and a structural design of equipment for substantially or totally providing and/or rendering Class A waste forms and preventing the formation of Class B, C and GTCC waste forms. The invention also provides both ion exchange and filtration of liquid radioactive wastestreams. | 12-06-2012 |
20130153473 | CONCENTRATE TREATMENT SYSTEM - In one aspect the invention provides a system for treating a wastestream, particularly a radwaste, for safe disposal and, in final processing converting it into one or both forms including an aqueous form for safe discharge to the environment and a solidified form for safe disposal. In another aspect the invention provides the capacity to employ a step where a specific target element strategy can be set up synchronizing sorbent substance choices and multiple recycle options to remove target substances from wastestream as a part of its Sorption or Powder Sorbent Isotopic Reduction step (II). Other steps cooperate with Sorption step (II) including Oxidation (I), Solid-Liquid separation (III), and Selective Ion Exchange (IV) to deliver the wastestream to final processing. | 06-20-2013 |

20150221404 | CONCENTRATE TREATMENT SYSTEM - One aspect of the invention provides a system for treating wastestream, particularly a liquid or aqueous radwaste, for safe disposal and, in final processing, converting it into one or both forms including an aqueous form for safe discharge to the environment and a solidified form for safe disposal. Another aspect provides the capacity to employ a step where a specific target element strategy can be set up synchronizing sorbent substance choices and multiple recycle options to remove target substances from wastestream as a part of its Sorption or Powder Sorbent Isotopic Reduction step (II). Other steps cooperate with Sorption step (II) including Oxidation (I) to inactivate or destroy existing chelants, Solid-Liquid separation (III), and Selective Ion Exchange (IV) to deliver the wastestream to final processing. Still further aspects of the invention address the recovery and safe handling of substances such as C-14 ( | 08-06-2015 |
20150321936 | METHOD FOR RESIN, SOLIDS, AND SLUDGE SOLIDIFICATION, STABILIZATION, AND REDUCTION OF DISPOSAL VOLUME - A method for solidification of a waste material is provided. The method includes removing excess water from the waste material, mixing at least one polymer with the waste material to provide a polymer-waste mixture, and curing the polymer in the polymer-waste mixture to provide a solidified monolith waste form having a continuous polymer matrix encapsulating the waste material. | 11-12-2015 |
