The Criticality Safety Analysis of the Spent Fuel Storage Pool Area I in Small Modular Reactor

Abstract:

Based on the Monte Carlo calculation method, geometric model of spent fuel storage pool Area I of small modular reactor is established, assuming infinite 6×6 type storage racks. Calculation results show that the reactivity is maximal when the water density is 1.0g/cm3. The value of k_eff is 0.8729 in normal storage condition. The spacing of storage racks in spent fuel pool would change in an earthquake accident condition. The values of reactivity of spent fuel pool in the assumed earthquake accident condition are also calculated. The values of k_eff are between 0.872 and 0.876. Both in normal condition and assumed earthquake accident condition, the values of k_eff are less than 0.95, to meet nuclear safety regulatory requirements.
