In a typical steam power plant, the boiler feedwater (BFW) pump takes suction from the deaerator (DA) and discharges high-pressure water to the boiler through the feedwater heaters. During normal ...

Ten days later, it said cracks of a few centimetres had been identified in all four of the feedwater pumps. The feedwater pumps are Olkiluoto 3's largest pumps and are used to pump water from the ...

In the feedwater pumps, water from the feedwater tank is pumped into the steam generators. Operator Teollisuuden Voima Oyj (TVO) said the damage detected at the pumps has no impact on nuclear safety.

During a deaerator pressure transient, the actual pressure at pump suction decreases as the deaerator vapor pressure decays. However, due to hold-up of the hot-water slug in the pump suction line ...
