Transmutation of burnup products for a typical VVER-1000 reactor in fusion-fission hybrid has been investigated using MCNPX 2.6.0 calculation code. Burnup fission was performed 1000 MW practical power VVER core UO2 fuel and light water as its coolant moderator, well. The have classified separated according to their half-lives usages, the remaining wastes were used fuels reactor. also implemente...

The bioremediation of 2,4,6-trinitrotoluene (TNT) contaminated soil was performed on a laboratory scale. To compare bioremediation methods, a soil slurry reactor and a soil column reactor were operated and the effects of supplemental sources were investigated. Optimal conditions for the two bioremediation systems for the removal of TNT were obtained. In the soil slurry reactor, about 60% of the...

The design and the construction of an actual 8.7-m3 pilot/full-scale biotrickling filter for waste air treatment is described and compared with a previous conceptual scale-up of a laboratory reactor. The reactor construction costs are detailed and show that about one-half of the total reactor costs ($97,000 out of $178,000) was for personnel and engineering time, whereas approximately 20% was f...

A shaft-type activated sludge reactor has been developed in order to study the feasibility of high-rate wastewater treatment. The reactor having volume of about 14.5 L was operated with the acclimated mixed activated sludge under batch and continuous mode using a synthetic wastewater as feed. The batch study was performed with varying chemical oxygen demand (COD) concentrations of 1000–3500 mg·...

Syn sulfoxide elimination was carried out under continuous-flow conditions in a mesofluidic thermolysis reactor. The design of the reactor enabled accurate control of reaction time and conditions, affording a convenient scale-independent procedure for the production of N,C-protected vinylglycine derivatives. Thermolysis at 270 °C under 1000 psi of pressure in superheated toluene enabled typical...

The growth of green energy technologies within the frame 7th Sustainable Development Goal (SDG) along with concern about climatic changes make nuclear an attractive choice for many countries to ensure security and sustainable development as well actively address environmental issues. Unlike equipment (immovable goods), which are often well-catalogued analyzed, design manufacturing codes their s...

In this paper, neutronic calculations and the core analysis of VVER-1000 reactor were performed using MCNP6 code together with both ENDF/B-VII.1 ENDF/B-VIII libraries. The effect thorium introduction on parameters was discussed. reference initially filled enriched uranium oxide fuel then fueled uranium-thorium fuel. determine delayed neutron fraction βeff, temperature reactivity coefficients, c...
