针对田湾核电站VVER堆型六角形乏燃料组件干法贮存容器开展采用燃耗信任制技术的密集贮存临界安全分析研究,燃耗计算使用APA-H程序包中组件参数计算程序PHOENIX-H,临界计算使用MCNP5程序。计算分析对象为国外VVER型核电站乏燃料干法贮存容器VSCVVER。利用MCNP程序建立VSC-VVER粒子输运模型,进行新燃料假设下的临界安全分析。计算中出于保守性考虑,假设整个干法贮存容器MSB及VCC空气流动通道内充满0℃纯水,计算采用
Aiming at the dry storage container of VVER reactor-type hexagonal spent fuel assembly in Tianwan nuclear power plant, the critical safety analysis of intensive storage using fuel-burn-trust system is carried out. The fuel consumption calculation is based on the calculation program PHOENIX-H of component parameters in APA-H package, Calculate using MCNP5 program. The calculation and analysis target is the spent fuel dry storage container VSCVVER of foreign VVER nuclear power plant. The MCNP program was used to establish the VSC-VVER particle transport model to carry out the critical safety analysis under the new fuel assumption. For conservation purposes, it is assumed that the entire dry storage container MSB and VCC air flow channels are filled with 0 ° C pure water, calculated using
