Particularities of Steel Structural Elements of Reactor Facilities with Heavy Liquid Metal Coolant

Abstract

The experimental investigations performed at NGTU of the characteristics of the near-wall layer in the flow of a heavy liquid metal coolant as well as the influence of the regime parameters of the loop (velocity of liquid metal coolant over contact surfaces, thermodynamic activity of oxygen, coolant temperature, and circulation time) on the change of its operating characteristics – surface roughness of the structural material during prolonged contact with high-temperature coolant flow (lead, lead–bismuth) – are analyzed.
