Long term post-test simulation of the FFTF natural circulation tests using SSC
As part of the validation of the Super System Code (SSC), the Fast Flux Test Facility (FFTF) scram to natural circulation tests were simulated using SSC. A previous assessment of these simulations, was limited to short time scales (0 to 6 minutes) and concentrated on in-vessel parameters, in particular, the coolant temperatures in the fueled open test assemblies (FOTA's). In the short term, SSC predictions were found to be in good agreement with the experimental data. This report summarizes the results of the comparisons over the long term (60 minutes) and concentrates on the various loop parameters, hot leg temperatures, cold leg temperatures, and loop flow rates. For all tests, SSC predictions were in excellent agreement with the test results.
