<p class="Default">Calvert Cliffs has plans to reduce the level of zinc in the Reactor Coolant System from a target level of 8 to 12 ppb to a new target of 4 to 6 ppb. This change is due to a study showing that Calvert Cliffs has a fully formed zinc film on
the RCS piping. Reducing the RCS zinc level is designed to save the cost of additional zinc without having any impact on source term.<o:p></o:p></p>
