堆芯的一半都暴露在水面上，主回路中水的辐射水平达到正常标准的350倍。

Half of the core is now uncovered, and the radioactivity of the water in the primary loop is 350 times its normal level.

15小时50分钟随着主回路的水泵启动，循环水包围了堆芯。

15 hr 50 min the primary loop's pumps are turned on, which circulate water around the core.

在这起事故中，低劣的控制室指示器指引电站工作职员封闭了为反应堆芯堆降温的回路。

In that case, poor control room indicators led plant officials to switch off the circuit which would have cooled the reactor core.
