TRITIUM DETECTED IN GROUNDWATER BENEATH PLANT BUILDINGSDESCRIPTION:On August 9, 2006, the plant staff detected measurable tritium (hydrogen-3) in small amountsof ground water found at several locations beneath the auxiliary and turbine buildings. Thegroundwater had infiltrated into narrow shafts beneath the two buildings which are used tomeasure possible settling of the structures.Tritium measurements, detected in four shafts, ranged from 282 picoCuries per liter (near thelower level of detectability) to 103,000 picoCuries per liter. The shafts are not interconnected. The levels measured do not meet the threshold for reporting to the NRC, but the licensee hasinformed local and state agencies of the situation. The licensee reported that no detectablelevels of tritium have been found in environmental monitoring wells both on and off the plantsite.The licensee is investigating possible sources of the tritium and plans to evaluate the situationfurther. The onsite NRC resident inspectors and an NRC radiation specialist have reviewed thelicensee's analytical results and continue to monitor the licensee's activities.The information in this preliminary notification has been reviewed with licensee management. The licensee issued a news release on August 11, 2006.The licensee notified the NRC Operations Center of this situation at 3:40 p.m. CDT onAugust 10, 2006. This information is current as of 9 a.m. CDT on August 14, 2006.CONTACTS:Stephen BurtonPatrick Louden920-388-3156630-829-9627}}
