Thermal Hydraulic Analysis of Vitrified Waste Product Storage Vault
摘要
Numerical analysis has been carried out for the vitrified waste product storage vault. Four canister numbers are stored one above the other at a single storage location. The centreline temperature of vitrified waste product is the controlling parameter. The maximum centreline temperature should not exceed 500 °C (Mishra et al. in Int J Therm Sci 173:107429, 2022 [1]). The temperature profile is obtained at different power levels by varying the velocity in the annular region. The maximum centreline temperature is obtained to be 326 °C for an annulus velocity of 0.5 m/s at the maximum expected heat generation rate of 1.8 kW. The blockage of one of the two vault outlets can cause a drop-in flow rate by 20% to 22%.
