Development of joining procedure for pole pieces of the electromagnet of the diverse safety rod in a fast breeder reactor

0
In the prototype fast breeder reactor, the electromagnet for the diverse safety rod is welded using a non-magnetic filler to separate the magnetic poles. The pole pieces are made of soft iron, and the non-magnetic nickel base ERNiCr-3 was chosen as non-magnetic filler wire. The procedure followed for joining the pole pieces consisted of weld build-up of the inner and outer core pieces with ERNiCr-3 filler material and machining to the required dimensions. The final joining of the electromagnet was by a circular joint at the contact end. The joints were qualified by stringent inspection procedures, including leak testing.
