Abstract EN
The behaviour of a parallel-channel natural circulation boiling water reactor under a low-pressure low-power startup condition has been studied numerically (using RELAP5) and compared with its scaled model.
The parallel-channel RELAP5 model is an extension of a single-channel model developed and validated with experimental results.
Existence of in-phase and out-of-phase flashing instabilities in the parallel-channel systems is investigated through simulations under equal and unequal power boundary conditions in the channels.
The effect of flow resistance on Type-I oscillations is explored.
For nonidentical condition in the channels, the flow fluctuations in the parallel-channel systems are found to be out-of-phase.
