Dominion Energy is an energy company headquartered in Richmond, Virginia. Dominion Energy operates the Millstone Power Station in Waterford, Connecticut. The Millstone Power Station produces enough electricity to power an estimated two million homes. Feedwater pumps are the pumps in the water-steam cycle of a nuclear reactor system that control the amount of water being sent to the steam generators. The first operating unit at the Millstone Power Station, Unit 2, implements a control algorithm for its feedwater pumps that optimizes the amount of water flow to the steam generators. Dominion Energy has expressed a need to implement a similar control algorithm for the feedwater pumps in the second operating unit, Unit 3. Dominion Energy wants to develop a control algorithm for the feedwater pumps in Unit 3 through the use of a software model. The software model must accurately model the physical system.
