“…The IAEA Research Reactor is a pool-type MTR, 10 MW. The core is cooled by light water in a forced circulation mode with an average coolant inlet velocity of 3.55 m/s, the operating pressure of 1.7 bar, inlet coolant temperature of 311 K and the core coolant flow direction is downwards [13]. Simulated flow blockage observations using the reactor data have been carried out for one sub-channel with an 80 % blockage ratio and several blockage positions including the inlet, middle, and outlet, in which no boiling occurs in all blockage cases [9].…”

“…This event is simulated by assuming that the reactor is in operation at nominal power of 50 MW, primary coolant flow rate of 900 kg/s, and coolant pressure of 8 kgf/cm 2 and power supply is suddenly lost. This event is simulated using a transient computation code, Table 1: Potential accidents on primary coolant system [8].…”

“…The fundamental laws of mass, momentum, and energy conservation for irregular shape with constant control volume V, and surface area S, are as follows (Liepmann, 1957;Delhaye, 1981) [8]: Simulation of loss of coolant flow is carried out using PARET-ANL code. Before transient calculation is performed, steady state condition should be identified first where it is assumed that the reactor has been in operation for 24 hours so that equilibrium condition is achieved.…”

“…Estas modelagens são capazes de apresentar características específicas dentro de um determinado domínio computacional, que muitas vezes só poderiam ser observadas com o uso de laboratórios e equipamentos específicos e muitas vezes inacessíveis a maioria dos centros de pesquisa.
