INADVERTENT OFFSITE NOTIFICATION DURING SIMULATOR TRAINING
"At 0749 PDT on March 21, 2012, during a training scenario in the plant simulator, plant personnel inadvertently issued an Alert notification for Diablo Canyon Power Plant (DCPP), Unit 1. This Alert should be disregarded. The Alert was issued as a loss of the Unit 1 fuel cladding barrier with no radioactive release. There is no Alert declaration at DCPP Units 1 or 2, and both units are operating normally. DCPP contacted notified parties to clarify that the Alert notification was inadvertent.
"DCPP is making this 4-hr, non-emergency notification under 10 CFR 50.72(b)(2)(xi) as a situation for which an (inadvertent) notification to other government agencies has been made."
The licensee is investigating this inadvertent notification but believes that the notification system was still set up from the emergency plan drill which was conducted last week.
The licensee notified the NRC Resident Inspector, San Luis Obispo County, and the State.

AGREEMENT STATE - PROCESS GAUGE SHUTTER STUCK IN OPEN POSITION
The State of Illinois reported the following information via email:
"The Wood River Refinery reported that a shutter mechanism on a fixed gauge (Ohmart Model SH-F1B, S.N. 2508CN) was found stuck in the open position during a routine survey and maintenance check. The gauge contained a 3.7 GBq (100 mCi) Cs-137 source. Staff were unable to return it to the shielded position. The gauge is in an unoccupied area.
"The device/area has been posted. Surveys indicate normal radiation levels in the vicinity of the device compared to the SSD registry. There is product in the vessel and 2 other gauges are in the vicinity.
"Personnel and shift managers have been informed of the situation. A service vendor has been on scene and so far has been unable to close the shutter after lubrication. Additional service measures are being pursed by the vendor."
IL Item No. IL12005
