PFBR is a liquid sodium cooled pool type fast breeder reactor. Reheater, a part of the steam generating system, is a vertical shell and tube type heat exchanger. The main construction material is 9 Cr - 1 Mo steel 85 no. tubes of 31.8mm O.D. and 2mm thickness are butt welded to tube sheet spigots at both the ends. These joints call for the highest level of integrity and reliability because of the possibility of potential interaction between sodium and steam.
