Slip-bearing operation in dense liquid-metal coolants at nuclear power plants

It is presented the results of experimental and numerical investigations in respect to wearing processes occurring in different steel and iron sliding bearing supports of vertical shafts (of pumps and engagements) operating in lead medium, and in the mediums of lead-bismuth and lead-lithium eutectic alloys, if the temperature is less than 510°C, the admixture of thermodynamically active oxygen in molten metal is from 10 up to 10, and there is the solid phase of coolant oxides.
