Joining of D9 steel fuel-clad to SS316LN with end plug by magnetic pulse welding

摘要: [en] Generation and utilization of high frequency, high intensity pulsed magnetic fields to produce fuel pin end-plug enclosures on claddings of interest to the Prototype Fast Breeder Reactor (PFBR) program of the Department, is demonstrated. Accelerator and Pulse Power Division (APPD), Bhabha Atomic Research Centre has developed strong reinforced coils and 70kJ, 25kV Electromagnetic Manufacturing Machine (EMM), for forming and welding applications. The paper thus highlights the steps in design and qualification tests conducted on the MPW samples pertaining to D9 and SS316LN axis-symmetric geometries employed in PFBR fuel core assemblies. Attempts are on to accomplish the in-core joint testing
