Corrosion and SCC resistant materials and chemistry for SCWR design
FY 2013-14
Summary
The present proposal addresses Development Priorities for 2012-16, in which it was stated that ""research isrequired to identify and test classes of candidate materials that can be used for in-core and out-of-corecomponents, including a fuel channel design for a core outlet temperature of up to 625°C and a suitable fuelcladding material (up to 850°C during normal operation and higher temperatures during short upsetconditions)"", and ""material performance will need to be demonstrated in the key areas of corrosion and stresscorrosion cracking (SCC), as well as mechanical properties such as creep."" Based on our previous success onassessing existing materials in terms of their performance under the conditions expected in the Canadiansupercritical water reactor (SCWR) concept and in determining the mechanisms governing the occurrence ofcorrosion and SCC under SCWR conditions, the current proposal focuses on important unresolved issues: 1)identify the role of SCW properties in the dissolution of elements from candidate alloys; (2) development ofreliable methods of surface modification for enhanced corrosion protection; (3) understand the effects ofmaterials composition on corrosion and SCC susceptibilities; and (4) expand the SCWR database by generatingrequired information on material susceptibility to corrosion and SCC under SCWR conditions. The researchwill generate new knowledge/technology with a strong potential to strengthen Canada's nuclear industry and tofulfill Canada's obligations under the GEN IV International Forum (GIF) agreement. The research will beconducted in collaboration with AECL and NRCan. These two leading organizations in Generation IV researchand development will contribute directly to the research work defined in the proposal, will provide guidance onthe direction of research, and will assist through coordination with other researchers in the field. The researchprogram also will provide training for a number of highly qualified personnel in the areas of nuclear materialand chemistry control for SCWR.
