LVN-2000 Eliminates Chronic Maintenance, Performance & Safety Concerns At Exelon Nuclear Power Plant

The Exelon Nuclear, Limerick Generating Station in Limerick, PA injects sodium hypochlorite into the lower basins of two cooling towers to treat the circulating water and protect the condenser from biological fouling. For many years, the oxidizing biocide had been delivered to the cooling water systems via positive displacement chemical metering pumps, with each cooling tower served by two 4 GPM pumps.

The previous sodium hypochlorite feed system had been plagued from the onset by leaks, metering pump maintenance concerns, and poor chemical performance. “The pump and system PVC piping suffered severe fatigue and failed at mechanical joints, due primarily to the pressure/velocity pulses generated by the pumps,” says Eric George, chlorination system manager for the station.
