2002:08 Mammography – recent technical developments and their clinical potential
development. Material and methods The scientific literature has been reviewed, conferences covered and contacts with colleagues developed. Companies in the field have been inquired and invited for presentations ... stage. Equipment for digital mammography is commercially available both with small area and full field technique (FFDM). The development of FFDM systems is now intense, as well as the development of dedicated...

2011:19 Experimental evaluation of influence from residual stresses on crack initiation and ductile crack growth at high primary loads
weld-induced residual stresses in some materials, for instance stainless steel welds. The R6-method on the other hand tends to give overly conservative assessment results. The significance of the secondary ... materials within nuclear applications has been studied earlier using an analytical approach by a SSM-financed study (SSM Research Report 2009:27). In that study a deterministic safety evaluation procedure was proposed...

2023:14 Effect of gamma-irradiation on the redox states of the structural iron in bentonite clay
SSM perspective Background Bentonite clay is used as buffer and backfill material which form engineered barrier in the spent fuel repository. The buffer material surrounding the copper canister will be ... physicochemical properties of bentonite clay, such as swelling. In this study, the focus is on such radiation effect on compacted bentonite. Results Molecular dynamics simulations show that the water radiolysis...

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...

2017:20 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...

2019:10 Rapport från SSM:s vetenskapliga råd om ultraviolett strålning 2018
SSM:s perspektiv Bakgrund Statens strålskyddsinstitut, SSI, utsåg ett vetenskapligt råd för frågor om ultraviolett strålning 2002. I rådet ingår vetenskapliga experter inom områdena onkologi, dermatologi ... meteorologi. Efter en omorganisering av arbetet kring strålsäkerhet så bildades Strålsäkerhetsmyndigheten, SSM. Myndigheten tog över ansvar och uppgifter från Statens strålskyddsinstitut och Statens kärnkraftinspektion...
