2017:16 Stress intensity factor solutions for circumferential cracks in cylindrical bars under axisymmetric loading and global bending
Background The case of a circumferential crack in a cylindrical bar has not been available in the ProSACC code. The need for such a geometry, especially considering nonlinear axisymmetric loading and global bending, has motivated the development of new stress intensity factor solutions, also known as K-solutions. These new K-solutions will be available in ISAAC, the successor to ProSACC.

Nuclear power
Nuclear power currently represents approximately 30 per cent of Sweden’s national power supply. There are three nuclear power plants in the country, with a total of six reactors in operation. These NPPs are the Forsmark, Oskarshamn and Ringhals plants. The Forsmark NPP has three reactors in operation. The Oskarshamn NPP shut down two of its three reactors in 2017. The Ringhals NPP shut down...

Decommissioning
When the operator of a nuclear facility (i.e. the licence holder) is to decommission the facility, this must be done in a way that protects people and the environment from radioactivity in the facility. The Swedish Radiation Safety Authority issues regulations governing the planning and undertaking of dismantling activities; what’s more, the Authority performs checks to ensure that the...

Physical protection
The Swedish Radiation Safety Authority imposes requirements for the physical protection of nuclear facilities and transports, for example protection against attacks and thefts of nuclear material. We monitor and check that the nuclear power industry complies with these requirements. We also help to ensure interaction between man, technology and organisation in a way so that physical...

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.
