This thesis was conducted at Uppsala University during the spring semester 2016. The
thesis describes the development of a test equipment in purpose of analyzing how
stainless steel is affected by irradiation assisted stress corrosion cracking.
The purpose was to develop and design a test equipment in the software SolidWorks
and then perform simulations and calculations to make sure that the design fullfills
the specification of requirements. These simulations have been performed in the
software COMSOL Multiphysics.
In the beginning of the paper the theory about irradiation assisted stress corrosion
cracking is described, and how this can be associated with the lifetime of a nuclear
power plant. Pre-studies were done which included solid mechanics, material
knowledge and hydrochemistry. After the preparatory work the concept
development started. This was divided into five different concepts with continiuos
improvements. During this process, progress meetings were planned to evaluate the
concepts. Prior to every meeting with the supervisor and the subject reader one
concept was compiled. The design was in the end optimized by a simplified design to
make it easier to assemble and to minimize the consumption of material.
The result shows that the final design fulfills the technical requirements. The
simulations performed show that the design has a good safety margin which is
required to make sure that the design can withstand transients and small defects in
