Cs retention/chemisorption mechanism onto Reactor Coolant Boundaries Materials especially Stainless Steel (SS) & Ni-based alloys on the various temperature are being identified. Besides the importance of Si solute element that is already known, Ti is also detected playing an important role, especially at temperatures below 1050 deg. C.
