CORROSION PRODUCT DEPOSITION ON TWO POSSIBLE FUEL GEOMETRIES IN THE CANADIAN-SCWR CONCEPT
The present conceptual designs for the Canadian-SCWR call for the fuel to be arranged in bundlesas in the currently operating CANDU? reactors. Two potential bundle designs possessing anacceptable linear element rating (LER) have been identified: the subdivided and the internallycooled-annular-fuel (ICAF) designs. Potential corrosion-product deposition within the bundles is aconcern as fuel deposits will lead to a reduction in flow area increasing core pressure drop, willcause reduced heat transfer that may lead to fuel failure and will cause deposits to become activatedwhich may then be transported to the turbine resulting in out-of-core radiation fields and workerdose. In this paper, the magnitude and location of crud deposits in a Canadian-SCWR fuel channelare estimated through a corrosion-product deposition and transport model for both potential fueldesigns. Results predict a significant deposition of corrosion products as the water becomes criticalwith the flow area potentially decreasing by approximately 6.5％ after one year of operation.
