Four identical 37.5 Liter UASB reactors R1, R2, R3 and R4 were used to study the effect of sulfate concentration on granule formation. Diluted molasses with COD range 1000–1300 mg/l were used as feed and acclimated cow manure was used as seed. Concentration of sulfate ions in the four reactors were 100, 500, 1000 and 1500mg/l. Granules were observed in R2 after 33 days from startup time, while ...

The Advanced Liquid Metal Reactor (ALMR) Actinide Recycle System is being developed in the United States for application early in the 21st century. The ALMR is a major part of this system and has missions beginning with near-term (10 years), medium term (15-20 years), and long-term (beyond 20 years) horizons. These missions use the same reactor design with modifications only to the reactor core...

Cold-startup and hot-standby reactivity accident tests conducted at the SPERT III E-core research reactor are analysed with coupled neutron-kinetic/thermal-hydraulic code system DYN3D-ATHLET. Homogenised 2-group cross sections for DYN3D thereby generated Monte Carlo neutron transport Serpent 2 in combination ENDF/B-VII.1 section library. Results terms of maximum power, energy release, compensat...

BACKGROUND Biogas is a renewable energy carrier which is used for heat and power production or, in the form of purified methane, as a vehicle fuel. The formation of methane from organic materials is carried out by a mixed microbial community under anaerobic conditions. However, details about the microbes involved and their function are limited. In this study we compare the metagenomes of four p...

Changes in methanogenic population levels were followed during startup of a full-scale, farm-based anaerobic sequencing batch reactor (ASBR) and these changes were linked to operational and performance data. The ASBR was inoculated with anaerobic digester sludge from a municipal wastewater treatment facility. During an acclimation period of approximately 3 months, the ASBR content was diluted t...

This paper describes the application of Virtual Environment for Reactor Applications, VERA, under development by Consortium Advanced Simulation LWRs (CASL) to core physics analysis AP1000 PWR. The PWR features an advanced first with radial and axial heterogeneities which provides significant enhancements compared traditional cores, allowing best fuel usage short transition equilibrium cycle sub...
