The Canadian National Program on Generation IV Energy Technologies: Effects of radiolysis on materials degradation under sub- and supercritical water conditions
FY 2012-13
Summary
The viability of a supercritical Water Reactor (SCWR) will depend on the selection of appropriate reactor
system materials and their ability to withstand an extremely demanding environment. Sufficient knowledge to
defend predictions of long-term materials performance to owners and regulators requires a well-founded
understanding of radiation-induced supercritical water chemistry. The study of supercritical water chemistry
under continuous irradiation is an area of research that is exceedingly sparsely explored. It is, however,
important because continuous radiation leads to steady-state chemistry that controls water redox conditions.
Experiments will be performed on the steady-state radiolysis of supercritical water. The goal is to obtain data
that will validate radiolysis models for reactor coolant chemistry and thereby provide a basis for coolant
chemistry control specifications and reactor material selection.
