| Abstract | ||||
| In this study, it is intended to analyze early phases of a protected loss of coolant accident (LOCA) for MTR reactor. And to show the applicability of the presented model to the other similar types of research reactors. The transient situation since the time when coolant is beginning to be lost throughout one or more of the main coolant pipes which were supposed to be broken guillotine-like to the time when the core is totally uncovered is investigated. The modeling of the problem was separated into two phases; in the first phase when the water level of the pool is being decreased in a pre-estimated time-dependent way calculated by using modified Bernoulli Equation, the conservation equation are solved by using shooting method. The later phase, when water level reaches the top level of fuel plates and begins to decrease until the bottom of the core, and the fuel plates are being cooled by air. | ||||
