Tubbrott i en tryckvattenreaktor
Svenska tryckvattenreaktorer har tre ånggeneratorer som innehåller tusentals tuber. Reaktorns kylvatten (primärkrets) leds genom tuberna i ånggeneratorerna som överför värme till turbinsidan (sekundärkrets). På så sätt produceras ångan som får turbinen att rotera. Tuberna är en säkerhetsbarriär mellan kärnkraftverkets...

Nödkylning av en tryckvattenreaktor
En tryckvattenreaktor har olika kretslopp med vatten som skiljs åt i ånggeneratorerna. Det gör att energin kan flyttas utan att vattnet blandas. Vattnet i reaktorhärden hör till primärkretsen.

2016:16 Technical Note, Possible influence from stray currents from high voltage DC power transmission on copper canisters
Main Review Phase Introduction As part of the Swedish Radiation Safety Authority’s (SSM) review of the Swedish Nuclear Fuel and Waste management company (SKB) license application for a final storage for spent nuclear fuel, SSM has asked for complementary information regarding the effect of stray currents from high voltage cables on copper corrosion (SSM 2012). SKB therefore has performed an...

2016:21 The effect of a glaciation on East Central Sweden: case studies on present glaciers and analyses of landform data
The Swedish Radiation Safety Authority reviews and assesses applications for geological repositories for nuclear waste. When assessing the long term safety of the repositories it is important to consider possible future developments of climate and climate-related processes. Especially the next glaciation is important for the review and assessment for the long term safety of the spent nuclear...

2016:12 SSM’s external experts’ reviews of SKB’s safety assessment SR-PSU – engineered barriers, engineering geology and chemical inventory
Background The Swedish 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 of the 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...

2016:30 Measurement of Parameter Values for Predicting Corrosion Phenomena on Copper in Swedish HLNW Repositories
Passivity breakdown and pitting on pure copper, the assumed material for the canisters for the isolation of high-level nuclear waste in Sweden, has been studied in simulated, sulphide- and chloride containing granitic rock groundwater and the data are interpreted in terms of the Point Defect Model (PDM). The results indicated that a sulphide barrier layer forms on the copper surface, and that...

2019:04 Dosimetry in environments surrounding a laser-plasma accelerator
SSM perspective Background Modern laser technology makes it possible to generate ultrashort pulses with a very high peak power. At the Lund Laser Centre, a high-power laser facility in Lund, Sweden, laser pulses having a duration of approximately 30 femtoseconds are generated with a maximum peak power of up to 40 terawatts. When these pulses are focused, extreme light intensity is achieved.
