Turbines, economy extraction

The first reason was that this Government-funded project had cut comers to save money - power stations depend on everything working, so any normal power station would have two Condensate Extraction Pumps to pump water out of the turbine condenser, two Heater Drains Pumps to pump water through the feed heaters, and two Main Boiler Feed Pumps to drive water into the boilers. Each of the pumps could do the job by itself, but a redundant spare would normally be provided to ensure overall plant reliability. However, at PFR we only had one of each. This will have saved a lot of money during constmction, but it had been a false economy, since one failure meant the whole power station stopped making electricity.
