The Critical Heat Flux / Departure from Nucleate Boiling test loop provides a means of evaluating the DNB performance of test geometries representative of commercial pressurized water reactor (PWR) nuclear fuel. The test facility has operated at the Product Engineering Development Laboratory, which is part of the Westinghouse Columbia Fuel Fabrication Facility (Columbia, SC). The facility has been moved to our laboratory.
With a total power installed of 0.5 MW, 500 psia (3.5 MPa), independent cooling loop, dedicated cooling tower, the facility is able to host different fuel designs to generate new experimental data for current and advanced fuel designs.
Upgrades with state-of-the-art instrumentation for temperature and void fraction measurements, in conjunction with existing instrumentation installed is the key to success for this facility.
