The desulphurisation process for the Oxyfuel pilot plant was developed on the basis of the long-term proven flue gas limestone scrubbing process for SOx removal and other pollutants. Current operating results show that SO2 removal degrees > 99.5 % could be achieved. The tray has also been retrofitted successfully to three existing absorber systems (twincycle absorber). The operating modes and removal degrees were considerably improved.

By international comparison, the demolition of nuclear facilities in Germany began early, i.e. in the early 1980s. Those projects constituted virgin territory in the field of nuclear technology. There was no experience in applying existing codes, rules and regulations to the dismantling of activated and contaminated structures so as to protect personnel, the environment, and the public. Based on experience accumulated in the demolition of commercially used plants, Babcock Noell GmbH (BNG) handled some first projects in German research installations. This experience then allowed the company to solicit other demolition projects in research installa- tions in other European countries. One of the advantages which turned out to be useful was BNG's experience in the Russian WER nuclear power plant line (water-water reactor, Russian research reactor line) plus the fact that several research reactors of that design were to be decommissioned and demolished in countries in Eastern Europe. The objectives, organization and implementation of demolition projects of nuclear research installations are outlined for these facilities: Rossendorf research reactor (RFR), Dresden-Rossendorf, Germany; Joint Research Centre (JRC), Ispra, Italy, with 3 research reactors, various laboratories and waste stores; research reactor of the Salaspils, Latvia, Research Center; the FMRB reactor of the Federal Institute of Physics and Metrology (PTB), Brunswick, Germany; the FRF research reactor, Frankfurt, Germany and demolition of the Magurele, Romania, research reactor.

A three-element einzel lens is a standard ion optics used to focus a low energy ion beam. In certain applications like injection of a low energy ion beam into a strong magnetic field of a Penning trap, it is necessary to combine a lens with a small angle beam steerer. The middle electrode is often slit in parallel or diagonal in order to combine the steering field with the focusing field. Here we study and analyze the performances of these two designs of same dimension and show that the diagonal-slit configuration is the better choice to achieve comparatively larger steering and focusing within acceptable aberration. © 2011 IOP Publishing Ltd and SISSA.

A cobalt coincidence radioactivity detector is used to separate radioactive concrete dust from uncontaminated dust resulting from dismantling a nuclear power plant. A suction air stream carries the dust through a vacuum line to a cyclone segregator. The dust falls into a smaller first container from the segregator, and the detector detects radioactivity in the filled first container. The dust is transferred from the first container to a second container if the detected radioactivity exceeds a predetermined threshold. The dust is transferred from the first container to a third container if the detected radioactivity does not exceed the predetermined threshold. A filter collects the dust carried past the segregator by the suction air stream. If the radioactivity detected in the dust that collects on the filter exceeds the predetermined threshold, the dust in the first container is transferred to the second container before the first container is allowed to fill.
