てこ＼に縦形の海水ポンプを設備している。As a general rule, vertical pumps are used as seawater pumps for seawater intake equipment in nuclear couplants. In the case of horizontal pumps, seawater intake piping must be installed so that the impeller is always submerged in seawater to prevent idling during startup. In contrast to horizontal pumps, vertical pumps can be installed above the sea level and the impeller and water pipes can be immersed directly into the sea water. A vertical seawater pump is installed in the building.
