六边形套管型燃料堆芯核设计专用程序试验验证

采用六边形套管型燃料堆芯（HCTFR）7个零功率物理试验方案的试验数据对核设计程序（CELL+CPLEV2）的计算精度进行工程验证。验证结果表明，7个临界试验方案的临界棒位有效增殖因子（k_eff）计算偏差均在±0.8%以内，与试验结果符合较好，控制棒价值和停堆深度计算偏差也都在可接受范围内，表明CELL+CPLEV2程序具有较高的计算精度和可靠性，可用于HCTFR的核设计。 

Experimental Verification of Special Nuclear Design Code for Hexagonal Casing Type Fuel Reactor

Based on the experimental data of seven Zero Power physical test schemes of Hexagonal Casing Type Fuel Reactor (HCTFR), the calculation accuracy of the nuclear design codes CELL and CPLEV2 was engineering verified. According to the verification calculation results, the calculation deviations of the critical rod position effective multiplication factor (k_eff) of the seven critical test schemes are all within ±0.8%, which is in good agreement with the experimental results. The value of control rods and the calculation deviation of shutdown depth are also in the acceptable range, indicating that CELL+CPLEV2 has high calculation accuracy and reliability and can be used in HCTFR core design.
