2014:30 Modelling Approaches to C-14 in Soil-Plant Systems and in Aquatic Environments
Substantial expertise on carbon biogeochemistry already exists in the fields of plant physiology and aquatic ecology and therefore is it beneficial to draw on this to identify the important issues. A paper ... programme was published in Radiocarbon Journal. Further studies on C-14 (including modelling, model inter-comparisons, and experimental work) have been on-going by individual BIOPROTA member organisations and continued...

2012:61 Geochemical Constraints on Buffer Pore Water Evolution and Implications for Erosion
PCO2, SiO2(aq) and Na/Ca in groundwaters (and any future intruding glacial meltwaters) in the near-field at the site. This conclusion would not be evident from modelling approaches using mixing only. Modelling ... suggesting that the buffer may be partially altered prior to glacial meltwater intrusion. David Savage SSM English Mineralogical data from the Forsmark Site show that smectite and calcite occur at all depths...

2024:17 Atomistic studies on the adsorption and desorption of radionuclides on fuel crud and system surfaces in Light Water Reactors
SSM perspective Background Radiation safety is of particular concern during power plant maintenance. Radionuclides produced by the neutron bombardment in the core during operation may accumulate on system ... filter system or piping and contribute to the radiation field. Some ions that are prone to neutron capture often become trapped in the deposits on the fuel cladding surfaces, also called CRUD. It is important...

2017:22 Effect of weld repairs on residual stresses in nickel base dissimilar metal welds
affect the residual stresses through e.g. increased tensile stresses and increased plastic straining on the surfaces of the piping in contact with the light water reactor environment. This may in turn reduce ... by numerical simulation with two dimensional axi-symmetric assumptions. Conclusions are drawn based on comparison of the weld residual stresses before and after weld repair. The results show that the inside...

2016:23 Technical Note, Modelling of the thermal evolution of the KBS-3 repository at Forsmark and associated induced seismic activity
Phase Introduction The Swedish Radiation Safety Authority (SSM) reviews the Swedish Nuclear Fuel Company’s (SKB) applications under the Act on Nuclear Activities (SFS 1984:3) for the construction and operation ... encapsulation facility. As part of the review, SSM commissions consultants to carry out work in order to obtain information and provide expert opinions on specific scientific and technical issues. The results from...

sustainable and long term credibility of the Swedish financing system for nuclear waste liabilities. SSM conducts systematic examinations and reviews of the estimates submitted by the Swedish nuclear industry ... study for “bench-marking” purposes, in such cases when there is a need to supplement and correct field data from the industry. In the present study, data has been retrieved and organized such that the...

2014:22 Technical Note, Workshop on seismic hazard at Forsmark
This report describes the outcome of the workshop organized by SSM on seismic hazard at Forsmark that was held in Stockholm on the 4 and 5 of June, 2013. The report summarizes the issues discussed and ... and individual statements made by workshop participants should be regarded as opinions rather than SSM’s point of view. The participants had been asked to provide qualified, independent judgments for each...

2009:16 Influence of Hardening Model on Weld Residual Stress Distribution
Weld residual stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important ... present report is the result of an effort to acquire and to develop the latest research results in the field of WRS and especially the influence of hardening model. The choice of hardening model has been the...
