Developing and testing of the refuelling system mechanisms on the BN 350 reactor

A description is given of the stages of development in the construction of the BN 350 reactor refuelling system^mechanisms on the control assembly rig 'cold1 and fhotf tests of the overall

refuelling mechanisms prior to reactor startup.

Investigations in the choice of friction pair materials, testing of mechanisms on test rigs for development of the individual elements, fhotf tests of mechanisms in the coolant at working parameters for determining their range and the development of designs, testing of mechanisms in conjunction with control systems in the control assembly rig, adjustment and testing of mechanisms on the nuclear power sta tion indicate their adequate range and reliabi lity under normal operating conditions.
