| Popis: | International audience; This study presents the lead alloy system chemistry analysis for use as nuclear coolant orspallation target in ADS related systems in order to set down the needs for purificationprocesses and monitoring. The study is limited here to the 2 main impurities, oxygen and iron.The analysis of the various potential pollution sources that may occur during the variousoperating modes is given, as well as a first pollution rate assessment. In order to limit theconsequences in term of contamination (clogging) and corrosion, it is necessary to definespecifications for operation as regards oxygen and iron content in the fluid. As iron cannot bemeasured and controlled up to now, the best specification is to set the oxygen as high aspossible, defined by the cold leg interface temperature to ensure tolerable contamination, inorder to maximize the oxidation area to ensure corrosion protection by self-healing oxidelayer for the entire system. |
