    Abstract

    Changes in operational conditions may induce changes in the oxide films and rate of activity incorporation. To predict these changes and find means to affect activity build-up, experimental correlations between water chemistry, oxide film properties and activity incorporation are sought for. Flow-through cells have been installed in the sampling line of Loviisa unit 1 in order to collect the data needed when looking for such correlations. The main sources of activity in the samples are 110mAg and 124Sb. The 124Sb in-corporation was highest during the shutdown to refuelling outage and it seems to be a surface related phenomenon. Because of its long half life, 60Co is also an important isotope. The rate of 60Co content increase is highest during the start-up.
