Design basis and materials requirements for sodium heated steam generators for fast reactors

An attempt has been made to categorise the various materials, which have been considered for a sodium heated steam generator. Choice of steam generator, selection of material, problems of sodium heated generators, R&D efforts for indigenous materials for steam generators etc. have been discussed. It is concluded that stabilised ferritic steel will be a good selection as a sodium heated steam generator material under Indian Conditions. (Sarvashri S.C. Chetal & M.C.
