1 (2) Pressure transients in which sonic effects are not significant.
(3) Transients in which subcooled voids and thermal nonequilibrium are not impo rtant.
(4) Transients in which total flow reversal does not occur.
The code's thermal-hydraulic calculations can be performed for single-j phase liquid, two phase nucleate boiling, two phase film, boiling and single-phase vapor flow. In addition, the drift flux formulation used in the conservation equecions allows for both co-current upflow and countercurrent flow.
It is expected, however, that the code will be applied primarily to the single phase liquid and two phase nucleate boiling flow regimes in co-current upflow.
