Miscellaneous information
Unit 2 had its reactor vessel closure head replaced in 2007.
== Fishing around the power plant == The water around the plant (see lower-right-center of photograph) is a very popular place for anglers. Unit 1&2 each takes in bay water (from the fenced-in area) to cool its steam driven turbine condensers plus other bay water cooled primary and secondary system heat exchangers. The bay water is pumped out at a nominal flow rate of 1.2 million gallons per minute (75,000 L/s) per unit (Unit 1 and 2) for each steam turbine condenser. The water is returned to the bay being no more than 12 °F (6.7 °C) warmer than the bay water. Unlike many other nuclear power plants, Calvert Cliffs did not have to utilize water cooling towers to return the hot water to its original temperature, structures which are often associated with nuclear power plants. The warmer water encourages faster growth (relative to the surrounding area) of the small [[shellfish]], [[plankton]], and others at the base of the food chain. These attract the larger fish which are in turn sought after by the anglers. However, as the water comes out very quickly and creates a sort of artificial [[rip current]], it can be a dangerous place to fish.
CCNPP 3 will only need about 10% of the bay cooling water volume needed for Unit 1 and 2 combined. The increase in fish and shellfish impingement and entrainment will be less than 3.5% over Unit 1 and 2 existing conditions.
