Question:
11) A nuclear power plant is operating at full power when a 200 gpm reactor coolant leak occurs, which results in a reactor scram and initiation of emergency coolant injection. Reactor vessel pressure stabilizes at 900 psia. All centrifugal injection pumps are operating with all pump miniflow paths isolated. The shutoff heads for the pumps are as follows:
High pressure coolant injection (HPCI) pumps = 1,200 psia Low pressure coolant injection (LPCI) pumps = 200 psia
If the injection pumps continue operating under these conditions, which pumps are more likely to fail, and why?
Can please provide an answer why the answer is A in graph form and math format.
