| 摘 要： | 基于自主研制的三维中子-光子耦合输运蒙特卡罗通用程序JMCT（J Monte Carlo Transport Code），采用连续点截面，对国际基准屏蔽VENUS-III模型开展精细建模和中子输运临界及屏蔽计算.临界计算得到系统keff、重要区域的通量及能谱.结果表明，JMCT和MCNP程序的重要区域体通量计数吻合较好，偏差均在1%以内.深穿透屏蔽计算采用外源模式，点探测器计数，JMCT计算值与实验测量值偏差在15%以内，满足屏蔽设计对误差的要求.初步验证了JMCT程序临界及屏蔽计算的可用性.

| Abstract: | VENUS-III benchmark was simulated based on 3-D general-purpose Monte Carlo coupled neutron and photon transport code JMCT (J Monte Carlo Transport Code). It includes detailed modeling, criticality calculation and shielding calculation. Firstly, criticality calculation is done, in which keff eigenvalue, fluxes in importance regions and energy spectrums are calculated. Almost same results are achieved by JMCT and MCNP. Warp of keff is about 0.24% the flux warp is less than 1%. Then, deep penetration shielding is simulated, in which fixed source is used. Tally includes fluxes of detectors in different locations. Calculated results agree well with experimental data. The most warps of JMCT and tests are within target accuracy of ±15%. It satisfies requirement of shielding calculation. It shows that JMCT code suits well for criticality and shielding simulation. |
