Corrosion product transport in a water‐cooled nuclear reactor causes gamma‐radiation fields to grow around the heat transport circuit. An hypothesis is given which identifies some of the mechanisms causing radiation field growth in a CANDU direct‐cycle, boiling water reactor. Overall, predictions from a mathematical model of the hypothesis agree well with data. Comparisons are made for deposit weights of iron on fuel sheaths and for radionuclide specific activities in deposits on the fuel sheaths of the CANDU prototype direct‐cycle, boiling water reactor at Gentilly, Quebec. As well, radionuclide specific activities measured in particles in the water, and in deposits in the steam drums are compared with the model. Filtration of corrosion products from the reactor feedwater is suggested as one way to control radiation field growth.
