• The tenon of turbine blade of MAPS-2 LP rotor rear side third stage is made of AISI 414 material. During regular inspection it was observed that one of the tenons has eroded. It was decided to salvage by repair welding to reduce the reactor down time, accordingly a welding procedure Specification was prepared by MDTD, IGCAR. This novel technique developed by MDTD and CWD IGCAR was executed successfully at MAPS and completed the repair work in a single day which has reduced the reactor down time and resulted in considerable saving in cost.

• Dummy fuel subassemblies were fabricated for core mechanics experiments to validate PFBR core restraint system design and to check the mechanical interlock along with grid plate sleeve. An automatic GTAW system was designed and activated flux developed by the MDTD IGCAR was used for fabrication of Hexagonal sheath. To standardize the technique and meet the code requirement, welding procedure specification (WPS), procedure qualification record (PQR) and welder’s performance qualification (WPQ) were developed. Development of this technique has reduced total work content and increased the productivity considerably.

• Transfer Arm (TA) is the in-vessel handling machine of PFBR used to transfer fresh and spent core subassemblies (SA) within the main vessel. The rail and guide are designed to perform translation movement during operation. The relative motion between these components in the assembly at elevated temperature and sodium environment may lead to wear and self welding. To minimize such problems throughout the operating period of the reactor; these components are designed with hard facing deposit on its mating surfaces. The necessary hard facing technology was developed and executed at CWD.
