2022:04 Warm Pre-Stressing mechanisms
SSM perspective Background Swedish nuclear power plants (NPP) were originally designed and analyzed with an assumed operating period of approximately 40 years. As Swedish NPPs reach their original technical design life the safety of the additional operating time has to be verified. With increased operating time, the shift in the fracture toughness curve of the reactor pressure vessel (RPV)...

Magnetic fields
Magnetic fields are a part of our everyday lives and constantly surround us. Magnetic fields are generated by electrical devices such as refrigerators, coffee makers, hair driers, television sets and cordless phones. The strength of magnetic fields from household appliances and devices is normally very local and much lower than the Authority’s reference values, so they are not assessed as...
