The analysis of the long-term station blackout accident of BWR has been performed using the TRAC-BF1 code. The actuation of RCIC was assumed, and the results were compared with the data observed at the Fukushima Daiichi power plant unit 2 reactor. BWR-5 of 1,100 MW was analyzed, while the unit 2 reactor was BWR-4 of 780 MW. The reactor pressure and the core liquid level were, however, in good agreement with the observed data. It was confirmed that the quasi-steady state continued for a long time with the RCIC actuation. The timing of recovery action, which was composed of depressurization and coolant injection, necessary for the maximum clad temperature being less than 1,500 K was studied and compared with that of the unit 2 reactor.

Taconis oscillation in a closed long tube is studied by the numerical simulation of two-dimensional compressible Navier-Stokes equations. Conditions are used where both end walls of the tube are hot (T = TH), and the central regions of the side walls are cold (T = TC). The oscillation can be spontaneously generated when the temperature ratio (TH/TC) is larger than 7.1, whereas it can be damped when the temperature ratio is smaller than 5.7. We obtained two different critical temperature ratios and observed the hysteresis phenomenon.
