- The corrosion products are among the leading sources of radiation in primary coolant circuits of pressurized water reactors leading to prolongation of reactor down-time for routine maintenance entailing substantial loss of revenues. These deposits affect adversely coolant flow rates resulting in elevation of fuel and cladding temperature and become activated by high neutron flux in reactor core consequently creating high radiation field by accumulating in the out-of-core reactor components. In the case of light water reactors (LWRs), prevailing corrosion products include 59Fe, 99Mo, 56Mn, 58Co, and 60Co. The 56Mn is the leading corrosion product activity source during operation while cobalt isotopes dominate the activity after reactor shutdown. This paper presents a detailed discussion on some computer codes developed for prediction and transport of corrosion product activity in LWRs.
