1. Development of an Improved Thermal-Hydraulic Modeling of the Jules Horowitz Reactor
Sammanfattning : The newest European high performance material testing reactor, the Jules Horowitz Reactor, is under construction at CEA Cadarache research center in France. The reactor will support existing and future nuclear reactor technologies, with the first criticality expected at the end of this decade. LÄS MER
2. Investigation of a Biofilm Reactor Model with Suspended Biomass
Sammanfattning : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. LÄS MER
3. Upflow anaerobic sludge blanket reactor : modelling
Sammanfattning : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

4. Visionen om outtömlig energi : Bridreaktorn i svensk kärnkraftshistoria 1945–80
Sammanfattning : The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and 60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy, and thereby connected it to utopian ideas about an eternal supply of energy. LÄS MER
5. On measurement and monitoring of reactivity in subcritical reactor systems
Sammanfattning : Accelerator-driven systems have been proposed for incineration of transuranic elements from spent nuclear fuel. For safe operation of such facilities, a robust method for reactivity monitoring is required. Experience has shown that the performance of reactivity measurement methods in terms of accuracy and applicability is highly system dependent. LÄS MER
