在原非能动安全壳冷却系统分析程序（ＰＣＣＳＡＣ）的基础上，研究开发了对安全壳内部空间进行一维瞬态分析的ＰＣＣＳＡＣ１Ｄ程序。该程序能够模拟安全壳内部空间和外部环形通道中存在的自然对流和明显的温度落差，从而得出了非能动安全壳冷却系统温度等重要物理参数的分布。通过与Ｊ、Ｇ、Ｓｕｎ等人用ＣＯＭＭＩＸ分析ＡＰ６００的结果以及原ＰＣＣＳＡＣ程序的计算结果的比较，证明了ＰＣＣＳＡＣ１Ｄ程序提出的一维分析模型是合理可信的。
Based on the former PCCSAC (Non-Active Containment Cooling System Analysis Program), a PCCSAC-1D program for one-dimensional transient analysis of the containment interior was developed. The program can simulate the natural convection and the obvious temperature drop in the inner space of the containment and the outer annular channel, so as to obtain the distribution of the important physical parameters such as the temperature of the passive containment cooling system. By comparing with J, G, Sun et al. COMMIX analysis AP600 results and the original PCCSAC program results, it proves that the one-dimensional analysis model proposed by PCCSAC-1D program is reasonable and credible.
