Fortum Power and Heat Ltd. has revised the decommissioning plan for the Loviisa Nuclear Power Plant (Loviisa1 and Loviisa 2) at the end of the year 1998 [4-1]. The plan is based on immediate dismantlement after shutdownof the power plant. Experienced plant personnel will still be available to lead the decommissioning work. Onlythe radioactive plant systems, components and structures...

Data available in the literature of lattice parameter changes Ni, Cu and MgO single crystals irradiated neutron reactors are tentatively reproduced using ad hoc ion irradiation experiments. The nature energy ions were selected so that their weighted average recoil spectrum matches at best flux inside reactor. fluence was calculated to obtain similar, displacements per atom (dpa) levels. paramet...

A microbial fuel cell (MFC) is a device that converts organic matter to electricity using microorganisms as the biocatalyst. Most MFCs contain two electrodes separated into one or two chambers that are operated as a completely mixed reactor. In this study, a flat plate MFC (FPMFC) was designed to operate as a plug flow reactor (no mixing) using a combined electrode/proton exchange membrane (PEM...

At present, the commercial production of hydrogen is essentially carried out by catalytic steam reforming of hydrocarbons: natural gas and naphtha. However, the instability of the prices of natural gas makes the use of other raw materials increasingly attractive. This research focuses on the development of a technology for producing hydrogen from alternative resources, specifically from two typ...

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 ...
