1993:11 Methods for determination of strontium -90 in food and environmental samples by Cerenkov counting
dryness and ashed. Environmental and food samples are oven dried and ashed. The ash is dissolved in 1 molar hydrochloric acid and, at pH 1.0-1.2 the yttrium-90 is extracted from the solution with 10% HDEHP ... into 3 molar nitric acid and precipitated as hydroxide. The hydroxide precipitation is dissolved in 1 ml conc nitric acid, transferred to a liquid scintillation vial and the Cerenkov radiation from yttrium-90...

2017:18 FEM analysis of the mechanical integrity for the canister intended for storage of spent nuclear fuel with regard to copper creep ductility
vital importance. It has been shown that creep ductility for oxygen free copper can be very low (< 1 %). SKB has for this reason proposed to use oxygen free copper alloyed with small amounts of phosphorous ... criteria and postulated material behavior. Results show a required creep ductility in the range of 1% to 10%. It is concluded that the method used for this analysis is quite sensitive to several parameters...

2006:36 Mechanical Integrity of Canisters Using a Fracture Mechanics Approach
combined boundary element (BEM) and finite element (FEM) methods. The objectives of the project are: 1) to investigate the possibility of initiation and growth of fractures in the cast-iron canisters under ... new fractures or growth of existing fractures (defects) are very small, due to the reasons that: 1) the canisters are under mainly compressive stresses; 2) the induced tensile stress regions are too...
