Calculated and Sensitivity Analysis of Thermohydraulics Parameters of Bushehr Nuclear Power Plant (BNPP) Containment at LOCA Accident

Pressure investigation of air reactor containment at LOCA accident and sensitivity to inside and outside temperature of the reactor containment, include significant issues in the design of safety systems. In this study, the governing equations of different phenomena inside the reactor containment after accident has been modeled using visual basic. Following the results of modeling and sensitivity of temperature and pressure inside the BNPP containment is discussed, that represents insignificant effects of air changes in inside and outside temperature reactor containment on the pressure and temperature of the mixture of air and liquid is circuits caused by the accident.
