Modernizing I&C for operations and maintenance, one phase at a time
The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.

The compatibility of structural materials with lead and lead-bismuth eutectic is a significant challenge in the development of fast neutron reactors with heavy-liquid-metal coolants. Liquid-metal corrosion negatively affects ferritic-martensitic steel EP823-Sh. The mechanism of liquid-metal corrosion of steels corresponds to physicochemical dissolution when the oxygen content in lead is less than the equilibrium value. The selective dissolution of steel components from the surface of the claddings is observed. When the oxygen concentration exceeds the equilibrium value, the corrosion products are the outer oxide layer of magnetite and the chromium spinel of nonstoichiometric composition such as Fe(Fe1-x,Crx)2O4, as well as the development of an internal oxidation zone along the grain boundaries, which also can be observed. The pure-lead heat transfer sublayer between the fuel and the cladding causes the dissolution and deposition of steel components on the inner surface of the cladding. To increase corrosion resistance, it is proposed to modify the surface using plasma and laser processing, as well as by applying protective coatings.
