Abstract
Calculation of the primary circuit's coolant activation due to fission products (FPs) has been investigated for the eastern-type pressurized water reactor (VVER1000-V446). The reactor has been considered under normal full power operational condition for the first fuel cycle. Determination of the reactor coolant activity is based on time-dependent fission product core inventories. ORIGEN2.1 code has been used to determine the time-dependent fission product core inventories. The fission products activity in the primary coolant is calculated using a set of ordinary differential equations (ODEs) which governs the FPs concentration in the primary coolant. Results for 87 FPs have been calculated. The results of these calculations have been found to agree well with the corresponding available values found in the Final Safety Analysis Report (FSAR) of the Bushehr Nuclear Power Plant (BNPP).
