AI summary The pump in location 3A failed in 2010 and requires urgent refurbishment to prevent unit de-rating or outages. Each unit relies on two Circulating Water (CW) pumps for condenser cooling, critical for maintaining efficiency and vacuum levels. During warmer months, both pumps are necessary; failure of one could restrict load generation, while losing both would cause outages. The pumps, aged 18–23 years, suffer from wear and corrosion.

Why do this project now? The risk of a unit de-rating or outage is increased if the second pump is not available. Having this pump refurbished and re- nstalled as soon as possible will also mitigate the risk of future emergency repairs and...

AI summary Refurbishing the second pump is critical to avoid unit de-rating or outages, mitigate emergency repairs, and prevent extended forced outages if the remaining pump fails. Repair facilities are unavailable locally, necessitating refurbishment at an ISO 9002-certified facility.
