2017:33 SSM’s external experts’ review of SKB’s safety assessment SR-PSU – dose assessment, Kd-values, and safety analysis methodology
Radiation Safety Authority (SSM) received an application for the expansion of SKB’s final repository for low and intermediate level waste at Forsmark (SFR) on the 19 December 2014. SSM is tasked with the review ... application and will issue a statement to the government who will decide on the matter. An important part of the application is SKB’s assessment of the long-term safety of the repository, which is documented...

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...

2017:15 Radionuclide release rates associated with bounding cases featuring relatively early canister failures in a spent fuel repository
Swedish Radiation Safety Authority (SSM) for five years. During the review SSM commissioned the Southwest Research Institute (SwRI) to develop a model independent of SKB’s model to simulate the canister failure ... to isostatic load. SwRI built up the model based on their understanding of SKB’s model description. From SwRI’s modelling it could be confirmed that SKB’s modelling results were relatively consistent with...

2017:12 Computational assessment of LOCA simulation tests on high burnup fuel rods in Halden and Studsvik
in a Light Water Reactor (LWR). The lack of cooling and the drop in pressure impose large stresses on the nuclear fuel which would increase the risk of fuel rod damage and the subsequent release of active ... 5 (see SSM report 2015:37). Objective This report describes the validation of the models against tests performed in Halden and in Studsvik, the latter commissioned by NRC. The objective for SSM in this...

2017:36 Topical Peer Review 2017 Ageing Management Swedish National Assessment Report
Executive summary The European Union’s Nuclear Safety Directive 2014/87/EURATOM (NSD) requires the member states to undertake topical peer reviews (TPR) every 6 years with the first starting in 2017. The ... topic for the first topical peer review is ageing management. The Swedish Radiation Safety Authority (SSM) by the provision of the act of nuclear activities (1984:3) can decide by injunction that licensees...

2017:20 Assessment of inertia effects on transient clad-to-coolant heat transfer and coolant flow under reactivity initiated accidents
In this report, simple hydrodynamic models are used for studying the effects of coolant inertia on fuel-to-coolant heat transfer and coolant flow under reactivity initiated accidents in light water reactors ... SCANAIR fuel rod analysis program. The results of our study suggest that inertia has a negligible impact on the growth kinetics of the continuous vapour film that forms between the fuel rod cladding tube and...
