2003:14 Exchange processes at geosphere-biosphere interfaceCurrent SKB approach and example of coupled hydrological- ecological approach
The design of the repository for final disposal of spent nuclear fuel proposed by SKB is based on a multi barrier system, in which the geosphere and biosphere are the utmost barrier surrounding the engineer barriers. This report briefly reviews the current approach taken by SKB to account for hydrological and ecological processes at the geosphere-biosphere interface (GBI) and their future...

2003:12 Analysis of Critical Issues in Biosphere Assessment Modelling and Site Investigation
The aim of this document is to present a critical review of issues concerned with the treatment of the biosphere and geosphere-biosphere interface in longterm performance assessment studies for nuclear waste disposal in Sweden. The review covers three main areas of investigation: a review of SKB’s plans for undertaking site investigations at candidate locations for the development of a deep...

2002:14 Review of C-14 inventory for the SFR facility
The Swedish Radiation Protection Authority (SSI) is currently reviewing SKB’s continuing assessment for disposal of radioactive waste to the SFR facility at Forsmark. Among the wastes disposed are reactor operating wastes. Among the relevant radionuclides is C-14, which is relatively difficult to measure and to control because of its mobility. This report documents a review of the C-14...

2002:11 National plan for achieving the objectives of the OSPAR strategy with regard to radioactive substances
This report describes the Swedish plans for implementation of the OSPAR strategy with regard to radioactive substances. Revised release regulations for nuclear facilities are the primary tool in the work for achieving the objectives of the OSPAR strategy. The limitation of releases of radioactive substances shall be based on optimisation of radiation protection (ALARA) and the use of best...

1999:13 Determination of the Neutron and Photon Dose Equivalent at Work Places in Nuclear Facilities of Sweden
Various mixed neutron-photon fields at workplaccs in the containment of pressurised water reactors and in the vicinity of transport containers with spent fuel elements were investigated with spectrometers and dosimeters.The spectral neutron fluences evaluated from measurements with multisphere systems were recommended to be used for the calculation of dosimetric reference values for...

1993:11 Methods for determination of strontium -90 in food and environmental samples by Cerenkov counting
The procedure for determination of strontuim-90 (=yttrium-90) by HDEHPextraction of yttrium-90 and counting the Cerenkov radiation in a liquid scintillation counter, is applicable for all kind of samples. Prior to analyses liquid samples are evaporated to dryness and ashed. Environmental and food samples are oven dried and ashed. The ash is dissolved in 1 molar hydrochloric acid and, at pH...

2020:12 Assessment of the QT-COOL coolant channel module against the PBF RIA 1-2 experiment
SSM perspective Background The fuel rod analysis program SCANAIR has been developed by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) for analysis of reactivity initiated accidents (RIA) in light water reactors. The Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. This ensures a possibility...
