Loading Technique for Nuclear Fuel Rod of UO₂ Pellets and Its Improvement Based on Automatic Vibrating Loading Bench

Vibration frequency parameters are determined.Automatic process is easy to cause the positioning error of cladding tube,the grinding marks on cladding tube end,and thus affect the surface quality of fuel rods.Fuel rods grinding problem have be solved through the improvement of the automatic vibrating loading bench and auxiliary equipment,especially for the grinding defects on cladding tube end.This improvement also increases the stability and reliability of the automatic vibrating loading bench.
