In pressurized water reactors (PWRs), water in the reactor coolant system (RCS) is pressurized to prevent it from boiling. This high-pressure water is circulated through heat exchanger tubes in steam generators where heat is transferred to the lower pressure secondary coolant system (SCS), producing steam that is used to generate electrical power. The tubes represent a large fraction of the RCS pressure boundary and rupture of these tubes [a steam generator tube rupture (SGTR)] can result in a direct release of radioactivity to the environment. The principal radiological concern during an SGTR results from the presence of radioactive iodine in the RCS coolant. This study assesses the overall effects of the results of analytical and experimental investigations on the calculated iodine dose to the environment during an SGTR.
