   Författare :Patrik Dahlström; [2022]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. LÄS MER

3. 2. Kartläggning av ventiler innehållande Stellite i reaktornära vattensystem på Forsmark 2

   Sammanfattning : In the process of a boiling water reactor, high-levels of waste and radiation occur, where almost all the dose per person of the radiation in Forsmark are due to the radioactive iso-tope cobalt-60. The reason is that the stable isotope cobalt-59 is converted to the radioac-tive isotope cobalt-60 due to neutron irradiation in the reactor. LÄS MER
