尽管没有探测到任何核泄漏，但官员们担心系统故障可能导致反应器的核心过热。
No radiation leaks were detected, but officials are concerned the reactor's core may overheat due to a system malfunction.
这样就避免了一般固定床反应器中过热部位使催化剂减活的现象。
Thus the hot spot which causes catalyst deactivation in conventional fixed bed reactor is avoided.
所采用技术方案是，反应器2采用大外径、薄催化剂层的直管状，蒸发过热器16为列管式结构。
The adopted technology scheme is: the reactor 2 adopts the straight tube with large external diameter and thin catalyst. The evaporating superheater 16 has the tubular structure.
