However, some tanks and other compartments which are hydrostatically tested with seawater and painting has been provided already, to be washed down with freshwater after testing and to be totally dried and cleaned to the satisfaction of Owner's representative and paint maker's supervisors.

但是，如果一些舱和其他的舱室已经用海水进行了静水力试验并且已经提供了油漆，在实验后应该用淡水洗掉，完全干燥和清洗，使船东监理和制造商监理满意。

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.
