2018:08 Calculated radiological consequences of applying European clearance levels to scrap metal from the decommissioning of Swedish nuclear facilities
Background Many practices involving radioactive substances generate materials with potential or known radioactive contamination. Clearance of materials means a decision that such materials can ... the Studsvik melting facility are based on recommendations from the European Commission (RP 122 part 1 and RP 89, respectively). The clearance levels in the regulations will soon be changed to the values...

2022:13 Long-time variations of radionuclides and metals in the marine environment of the Swedish west-coast studied using brown algae
environmental samples. Results This project has resulted in the completion of a unique half-century[1]long time series of concentrations of radionuclides and metals in brown sea weed on the Swedish west ... concentrations of gadolinium, which most likely is a consequence of the increased use of gadolinium[1]based contrast agents for MR imaging in our hospitals. The metal analyses contributes to assessment...

2017:18 FEM analysis of the mechanical integrity for the canister intended for storage of spent nuclear fuel with regard to copper creep ductility
Background For final storage of spent nuclear fuel it is suggested by the Swedish nuclear fuel and waste management company (SKB) to emplace the nuclear fuel into copper canisters which are surrounded ... 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 phosph ...

2023:03 A novel method for retrospective analysis regarding appropriateness of radiological examinations
SSM perspective Background The use of X-ray diagnostic examinations, especially computed tomography, has increased in recent decades and it is essential that this increase is justified and ... evaluation of a larger number of examinations. The system provides a ranking and results in a score from 1 to 9 for a medical indication. Scores 1-3 are said to indicate usually not appropriate, scores 4-6 may...

2020:07 Fibre Clogging in Nuclear Power Plants
SSM perspective Background Emergency core cooling systems in boiling- and pressurized water reactors use strainers. Their purpose is to out foreign material suspended in the cooling water ... which result in regime I retention on the screen. For low approach velocity un, an addition of ca. 1% of the longer fibres which bridged the holes, was enough to retain the smaller fibres on the screen...
