2017:13 Monte Carlo patient-specific pre-treatment QA system for volumetric modulated arc therapy
increased. Current practices in Sweden normally compare the delivered dose with the planned dose based on measurements with different methods, for instance: portal dosimetry, point dose verification and/or ... and the performing of retrospective calculations and analysis. The Swedish Radiation Safety Authority's intention with the project is to contribute to a safer radiotherapy. Furthermore, the authority would...

2010:12 An Evaluation of Models of Bentonite Pore Water Evolution
implication of such bentonite chemical reaction is that radionuclide solubility and sorption depend on the buffer chemical conditions. Moreover, pore-fluid composition at the interface between the buffer ... bentonite buffer. In the more traditional buffer geochemical modelling approach, the focus has been on more reactive trace constituents such as calcite, gypsum and pyrite, but the potential bulk-transformation...

2017:02 Slow strain rate testing of copper in sulfide rich chloride containing deoxygenated water at 90 °C
conducted to a certain level of strain where after presence of cracking on the specimen surface were evaluated. Results Based on the results in this study, SCC in oxygen free copper material intended for ... threshold value of approximately 160 MPa. At lower sulfide concentration (~1·10−4 M), no SCC was observed on specimens. To some degree these results are consistent with other results found in the literature,...

2020:16 Estimates ofJ-integral and COD for circumferential through wall cracks under global bending including the effect of pipe end restraint
SSM perspective Background Leak-before-break (LBB) piping assessments have shown that piping systems can withstand long through-wall cracks before pipe rupture is expected. This is somewhat because pipe ... investigate what impacts the assumption degree of restraint at the ends of an analysed piping segment have on leak-before-break assessments and leakage rate calculations. Results The study conclude that crack...
