ith the arrival of the 115th U.S. Congress, the House of Representatives began hearings on the Nuclear Waste Policy Amendments Act of 2017. The legislation restarts Yucca Mountain as a repository for highly radioactive waste. In 1987, Congress amended the Nuclear Waste Policy Act of 1982, selecting Yucca Mountain, Nevada, as the only site to be studied, expecting the repository to open in 1998....

Semi-static dissolution tests using pressurized water reactor spent fuel rod segments and NNWSI reference J-13 well water 1n sealed stainless steel vessels at 85*C are being conducted In support of the Waste Package Task of the NNWSI Project. Test specimens include: bare fuel plus the empty cladding hulls, fuel rod segments with artificially induced cladding defects and water-tight end caps, an...

Woody biomass waste is generated throughout California from forest management, hazardous fuel reduction, and agricultural operations. Open pile burning in the vicinity of generation is frequently the only economic disposal option. A framework is developed to quantify air emissions reductions for projects that alternatively utilize biomass waste as fuel for energy production. A demonstration pro...

Impact of waste fuels (virgin/waste wood, mixed biofuel (peat, bark, wood chips) industrial, household, mixed waste fuel) and incineration technologies on partitioning and leaching behavior of trace elements has been investigated. Study included 4 grate fired and 9 fluidized boilers. Results showed that mixed waste incineration mostly caused increased transfer of trace elements to fly ash; part...

biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...

STUDY OBJECTIVE To determine whether there was a higher incidence of respiratory ill health in children living near to a cement works than in those from a different area, and if so whether the higher incidence was due to the use of a hazardous waste-derived fuel at the works. STUDY DESIGN A sample of the population of children living near the cement works (the study area) was compared with a ...

The magnitude of humanity’s energy needs requires that we embrace a multitude of various energy sources and applications. For a variety of reasons, nuclear energy must be a major portion of the distribution, at least one-third. The often-cited strategic hurdle to this approach is nuclear waste disposal. Present strategies concerning disposal of nuclear waste need to be changed if the world is t...

In the Advanced Fuel Cycle Research & Development (AFC R&D) activities, the uranium extraction (UREX+1) process is proposed as one of the most promising technique to separate transuranic elements (TRU) from light water reactor spent nuclear fuel in the years to come. The isotope Tc will be separated together with U within the first process steps. After the separation of U, Tc must be immobilize...

waste low density polyethylenes (ldpe) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. the effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. the effect of catalyst o...
