Accelerator System

An automated CO2 gas handling and injection system was developed. It is designed to dilute CO2 samples with blank gas in a mixing volume. The system is intended to be used for the characterization and quantification of 14C content in reactor graphite with accelerator mass spectrometry. A 100 kV accelerator system was developed to measure samples with high 14C content, to test the gas injection system and to measure the 3H content from gaseous releases of reactor graphite. Additionally, the Tandetron model 4130 was purchased from the Max-Planck Institute for Biogeochemistry Jena (Germany) and a concept was developed for installation at the accelerator building of the University of Cologne. With the new 3 MV system, new isotopic ratio measurements and ion beam techniques for material analysis can be performed. The system will be used for nuclear waste management measurements of isotopes, e.g. 3H, 14C, 36Cl, 41Ca and 55Fe, which are difficult to measure with other techniques.

The aim of the paper is to provide updated information on local opinion regarding the siting of a spent nuclear fuel repository in Finland. The main question is how the residents of the municipality perceive the threats and benefits of the repository. In accordance with the Decision in Principle by the Council of State passed in 2000, the Olkiluoto area in Municipality of Eurajoki was chosen as the location for the repository to accommodate spent nuclear fuel produced in Finland. Updated information on local opinions is needed as the siting process is approaching the next phase, the application for a construction license by 2012. The nuclear waste management company Posiva, owned by the utilities Teollisuuden Voima and Fortum Power and Heat, has also applied for a new Decision in Principle (DiP) for expansion of the repository. The data provided in this paper is based on a survey carried out in June 2008. The respondents were selected from the residents of the municipality of Eurajoki and the neighbouring municipalities using stratified random sampling (N = 3000). The response rate of the survey was 20% (N = 606). The paper is part of a joint research project between the University of Jyva¨skyla¨ and the University of Tampere. The research project “Follow-up research regarding socio-economic effects and communication of final disposal facility of spent nuclear fuel in Eurajoki and its neighbouring municipalities” is funded by the Finnish Research Programme on Nuclear Waste Management (KYT2010).

Excellent Work

The symposium “Scientific Basis for Nuclear Waste Management XVII” was held in June 15 – 19, 2003, in Kalmar, Sweden. The symposium, which was officially opened by the County Govenor of Kalmar County, Sven Lindgren, attracted 222 participants from 21 countries. Nearly 200 papers were presented during the three days of scientific sessions.Organizing a symposium this size requires the assistance of a large number of people involved both in establishing the scientific program and in planning and executing the practical organizational arrangements. Our window to the world, the symposium's homepage, was continuously kept up to date through the excellent work of Jonny Rönnfjord.
