10MW高温气冷堆屏蔽计算分析

Shielding Calculation and Analysis of 10 MW High-Temperature Gas-Cooled Reactor

高温气冷堆是第4代核能系统的重要堆型之一,由于其堆芯体积庞大、几何结构复杂,屏蔽计算难度较大。本工作使用三维SN程序TORT对10 MW高温气冷堆进行屏蔽计算,并用ANISN、MCNP程序进行校核。结果表明,TORT程序计算结果与ANISN、MCNP程序计算结果符合很好。

The high-temperature gas-cooled reactor is the important one in the generation nuclear system. Because of its large volume and complex structure, its shielding calculation is difficult. In this paper, shielding calculation of 10 MW High-Temperature Gas-Cooled Reactor was carried out by using TORT code, and the result was compared with those from ANISN and MCNP code. The comparison results show that they meet well.
