the control rod drive mechanism(CRDM) has been improved in the design
with some material substitutions and simplification of the manufacturing technology.The new design solved the problem of Ω-type weld leakage in upper part of the CRDM
and mechanical movement delay problem caused probably by friction between the spring and movable components.Step loss occurred during a function test of the prototype CRDM under atmospheric pressure and ambient temperature.This was analyzed and a further solution was employed.
