Abstract
The results of the solution of tribological problems emerging when friction units operate in heavy liquid metals as heat carriers in nuclear power plants are presented. An installation has been developed to simulate the vibrational wear of friction units in heat exchanging tubes of interfaced units with spacing gratings in order to simulate resistance to the vibration of the steam generator of a fast neutron reactor with lead heat carriers. A method of study has been developed, samples of tubes and spacing gratings have been tested for vibrational wear, and metallographic and profilometric exploration has been performed. The wear mechanism is described and the tentative life of the steam generator pipes is assessed.
