The new testing method of RH inconcrete was proposed firstly in the domestic, and it was applied to measure the water changes inconcrete induced by moisture diffusion and self-desiccation. The internal RH change rules of cementpaste and concrete with different water-cement ratios and cementitious material systems due tomoisture diffusion and self-desiccation were studied systematically.

In this thesis, firstly, some main models have been checked on their accuracy, and the reliability of MACORS code has been verified by the RELAP5/MOD2 code on five transient conditions for QSNP: loss of flow; loss of offsite power; incontrollable control rod withdrawal; the feed-water temperature increasing and the feed-water lost. The results obtained are very satisfactory. Secondly, MACORS is used to calculate the operating and accident transients for QSNP, and the analysis results are significant to real engineering. And finally for MNRS, MACORS is used to simulate the steady-state natural circulation heat-removed capacity and the transient behaviors from forced circulation to natural circulation. Some important conclusions are obtained by the analysis results.

本论文首先从各方面对核动力系统中最主要的、热工水力特性最复杂的反应堆和蒸汽发生器进行单独验证和理论分析，其次分别利用RELAP5/MOD2程序和MACORS程序对秦山核电站的双环路失流、全厂断电、反应性事故引入、主给水参数变化及丧失主给水五种瞬态工况进行了计算，结果符合很好，从而证明了本程序模型的准确合理性，选择数值方法的有效性和编制程序的正确性；尔后，利用MACORS程序对秦山核电站的多种运行及事故瞬态进行了分析，得出了具有工程价值的结论；对船用核动力装置的稳态自然循环载热能力以及相应参数的特性、强迫循环与自然循环的过渡工况等进行了仿真分析，所得结论对我国核动力船舶的设计，运行以及安全审评具有重要的意义。

Observation under optical and transmission electron microscopes showed that the Cu-contaminated leaves were thickened, with the expansion of leaf cell and the incrassation of palisade tissues.
