| 英文摘要 | Source term analysis not only can provide the fundamental data for radiation shielding design, but also has a guiding significance for in-service inspection of the reactor. A numerical analysis model (MAST1.0) for activated products in the secondary loop system of the molten salt reactor (MSR) was developed. The deviation of the simulation results between MAST1.0 and ORIGEN-S are less than 7%, which indicates that they are in good agreements. The amounts of the activated products (N-16, F-20 and O-19) and the corrosion activated products (Co-60, Fe-55, Mn-54, Cr-51, Ni-59, etc.) in the second loop were also obtained by MAST1.0, which show that the total activity of N-16, F-20 and O-19 is two orders of magnitude higher than that of the corrosion activated products in normal operating conditions. Flow rate has a significant effect on the distribution of N-16, F-20 and O-19 in the secondary loop. The total activity of N-16, F-20 and O-19 outside of the core increases monotonically with the increase of the flow rate. The concentration of N-16, F-20 and O-19 outside of the core tends to be stable, when the flow rate is greater than 1 x 10(6) cm(3) s(-1). Corrosion activated products show slowly increasing and decreasing trends in reactor startup and shutdown conditions, so they are the key radioactive sources for radiation protection after long-term shutdown of the reactor. |
