Daily Note, 4/1.7/09 On April 16, Exelon issued a press relase informing that, in the course of a c¢$$'
acement activity, it found about 3000 gallons of tritiated water in a concrete cable vault, having a tritium concentration of about 102,000 pCI/l. Exelon had previously informed New Jersey Department of Environmental Protection (NJDEP) and the

NRC of this matter. As part of its investigation to determine the source, Exelon sampled several on-site monitoring wells. A monitoring well in the vicinity of the cable vault and the Condensate Storage Tank (CST) indicated a tritium concentration of about 4,500,000 pCi/I. When last sample about a month ago, the monitoring well Indicated less than 200 pCi/I. Accordingly, Exelon is explarinn tha ntential that the lea source is the CST or associated piping, and has so informed the NJDEPi 2
