AGREEMENT STATE REPORT - PROCESS GAUGE STUCK SHUTTER
The following was received via fax from the State of Texas:
"On July 20, 2010, the Agency [Texas Department of Health] was notified by the licensee's Radiation Safety Officer (RSO) that while performing a routine test of the shutter on a Ronan Engineering nuclear gauge, the shutter failed to close. The gauge is a model SA-1 serial number 9724 GG containing 10 milliCuries (original activity) of Cesium (Cs) 137 and is used for level detection. The RSO stated that while they were trying to close the shutter, they applied too much pressure to the operating arm, and the operating pin which attaches the arm to the shutter sheared off. The shutter is stuck in the open position, which is the normal operating position for this gauge. The RSO stated that the current radiation level at one foot from the gauge is 0.015 millirem per hour, and presents no additional risk of radiation exposure to any individual. The gauge is located approximately 10 to12 feet off of the ground in an area that is not routinely occupied by individuals. This gauge, along with three additional gauges, are currently only used as a back up system. The RSO believes the gauge was installed in the late 1990s. The RSO stated that they will contact a service provider and either repair the gauge, or dispose of it."

OFFSITE NOTIFICATION TO THE COMMONWEALTH OF PENNSYLVANIA DUE TO TRITIUM DISCOVERED IN PROCESSED WATER
"PPL Susquehanna LLC personnel notified the PA DEP Bureau of Water Quality Management that Susquehanna Unit 1 experienced a large leak of river water in the turbine building on 7/16/2010 (reported under EN#46103). Efforts are currently underway to process that water prior to its return to the river. The NRC Resident Inspectors have also been notified.
"This notification is in accordance with 10CFR50.72(b)(2)(xi), in that an offsite notification has been completed regarding an event related to the protection of the environment."
The licensee reported to the PA DEP since the water that is being processed for return to the river contains less than EPA reportable quantities of tritium.
