Dynamic simulation of the Fast Flux Test Facility primary system
Description
Using the lumped parameter methodology, a computer model simulating the primary heat transport system (PHTS) of the Fast Flux Test Facility (FFTF) is developed. The three primary loops are simulated by two loops; a single and a double loop. The conservation of mass, energy and momentum are the physical foundations of the model FATFAD (FAst Flux Test FAcility Dynamics). To test FATFAD, three transients are initiated, (1) a ten cent step input of reactivity, (2) a ten cent step reactivity input plus a 50 degrees K rise in the secondary sodium temperature entering the IHX, and (3) a 25% reduction in Loop One's primary pump speed. The results show that FATFAD inexpensively and accurately simulates the PHTS of the FFTF
