Strålsäkerhetsmyndighetens svar på regeringens remisser
Regeringen fattade beslut om att godkänna ett slutförvar för använt kärnbränsle i januari 2022. Strålsäkerhetsmyndigheten svarade på regeringens remisser 2019–2021 inför beslutet. ...

Parallella tillståndsprocesser enligt kärntekniklagen och miljöbalken
Innan myndighetens stegvisa prövningsprocess för kärnteknisk verksamhet kan påbörjas krävs att verksamhetsutövaren beviljas tillstånd enligt kärntekniklagen. För att få tillstånd till kärnteknisk verksamhet krävs dock två separata tillstånd, ett enligt miljöbalken och ett enligt kärntekniklagen. Tillståndsprövningarna...

Extern granskning: Technical note och Internationell granskning
Som en del av Strålsäkerhetsmyndighetens granskning 2011–2018 tog myndigheten hjälp av externa granskare för avgränsade frågor. Det genomfördes även en internationell expertgranskning som samordnades av The Nuclear Energy Agency (NEA).

2014:57 Technical Note, Issues in the Corrosion of Copper in a Swedish High Level Nuclear Waste Repository: Phase III. Role of Sulphide Ion in Anodic and Cathodic Processes
The most important findings of this research project show that: In the case when the bentonite buffer between the copper canister and the granitic rock is not damaged, we can neglect the possibility of general corrosion damage being a threat to canister integrity over a 100,000 year storage period. However, if the bentonite buffer is damaged for any reason, and does not act as an engineered...

2014:48 Technical Note, Independent assessment of groundwater sulphide content in the long-te
Groundwater sulphide content is a key factor in the determination of canister lifetimes because of its role in corrosion of copper. SKB has based the canister lifetime analysis on a distribution of measured sulphide concentrations which are assumed to apply throughout the long-term analysis period. The distribution is based on expert judgement in the selection of samples that are regarded as...

2014:50 Technical Note, A Study of Availability of Fuel Data for Sweden’s Spent Nuclear Fuel
The study covers all types spent fuel planned to be placed in the final repository. It was carried out by selecting a sample of spent fuel and investigating the information available at the Nuclear Power Plants (NPP’s) in Sweden, the Central interim storage facility (Clab) and Studsvik. The results indicate that the required data is available and can be obtained for fuel unloaded after 1980.

2011:22 Infiltration of dilute groundwaters and resulting groundwater compositions at repository depth
The planned Swedish concept for final disposal of spent nuclear fuel includes copper canisters placed in deposition holes at about 500 m depth in granitic bedrock. The copper canisters will be surrounded by bentonite buffer with the objective of inhibiting groundwater flow adjacent to the canister. It has been discovered that dilute glacial melt-water may induce erosion of the buffer material.

2011:34 Evolution of hydrogen by copper in ultrapure water without dissolved oxygen
One result from this research was that the experimental difficulties of repeating Hultqvist and co-workers work are considerable and were initially underestimated. The main challenge was to obtain satisfactory tightness of all connectors involved in the experimental set-up. The problems with leakage resulted in that the research program originally planned for in this project had to be reduced...
