Scaling Factor Formation of FiR1 decommissioning waste

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


Characterisation of FiR1 decommissioning waste prior to dismantling has focused on formation of material specific scaling factors. In total, 15 scaling factors have been developed based on characterisation of original chemical compositions, activation calculations, and measurement of both easy-to-measure (ETM) and difficult-to-measure (DTM) radionuclides. Characterization work in the FiR1 project has improved VTT’s capabilities e.g. activity calculation software, sampling activated materials and measuring long-lived DTM nuclides. Characterization will continue during the reactor dismantling together with Fortum by collecting samples from areas which have been earlier inaccessible.
