摘要： A small-sized, light weighted vacuum circuit interrupter is provided. The interrupter comprises a vacuum container confining a vacuum atmosphere of a pressure less than 10.sup.-5 mmHg and a pair of electrodes at least one of which is a movable electrode for making and breaking an electric circuit including either a transformer of a rated surge voltage strength of less than 45 kV or a motor of a rated surge voltage strength of less than 25 kV. At least one of the electrodes has a contact made of a porous body of a refractory conductive material and an impregnate selected from the group consisting of silver telluride, silver selenide and mixtures thereof impregnated in the porous body in an amount sufficient to give the interrupter a chopping current of not more than 1A and an arc extinguishing capability at 1MHz of not more than 27 A/.mu.s when measured in a circuit of 6 kV. The interrupter can be connected to the load without a surge absorber for protecting the breaker from a surge voltage generated at the time of interrupting the circuit.

摘要： A method of production of a composite billet for a nuclear fuel cladding tube wherein a hollow inner billet of zirconium is inserted in a hollow outer billet of a nuclear fuel cladding material. Following insertion of a resilient member in the hollow inner billet, pressure is applied to the resilient member axially of the billets to force the inner billet against the outer billet, to produce a pressure bonding between an inner surface of the outer billet and an outer surface of the inner billet.
