"At 2003 on 6/10/07, the division 3 Nuclear System Protection System (NSPS) inverter power supply failed for unknown reasons. As a result of this failure, the High Pressure Core Spray (HPCS) system has been declared inoperable. This is a failure of a single train safety system and is reportable under 10 CFR 50.72(b)(3)(v)(D). Troubleshooting has been initiated to determine the cause of this failure."
The licensee notified the NRC Resident Inspector.

"This event is being retracted. An evaluation was performed and it was determined that no loss of safety function occurred following the failure of the Division 3 NSPS Inverter. The investigation determined that a circuit board failed on the inverter causing a blown fuse. The inverter was found in the reverse transfer position and AC power was automatically transferred to its alternate source, supplying its Division 3 loads. The High Pressure Core Spray system remained fully capable of performing its safety function to start and inject under both LOOP and LOCA conditions."
The licensee will notify the NRC Resident Inspector.

"Christus St. Francis Cabrini hospital called and reported an over exposure on a treatment using an HDR [High Dose Rate system]. The HDR system delivered a dose 40% more than what the treatment plan called for to the patient. The overexposure for the treatment was reported as 1400 cGy. This is all of the information we have at this time. An investigation has started for this incident."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text NEBRASKA AGREEMENT STATE REPORT - MISSING TRITIUM EXIT SIGN
The State provided the following information via email:
"The licensee purchased the facility in December of 2006 from Hartland Warehouse. Upon receiving the State of Nebraska's annual inventory of Generally Licensed Devices in April of 2007, they did an inventory and found the following sign missing: Isolite Exit Sign model 2040-01-02 containing 10 curies of H-3 in January of 1992 and serial #1135.
"The current licensee believes that the missing sign was located on the second floor of the office at one time. A door that led to a landing on the second floor and stair steps that led down to the first floor at sometime previously were torn down and the door blocked off. The licensee believes that the sign was removed and disposed of in the landfill."
Nebraska Event Number: NE070003
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

"At 11:03 hours EST, on July 7, 2007, the Plant Information Computer System (PICS) was removed from service to perform a planned modification to install and test a Standard Digital I&C System Platform (DICSP) infrastructure and to update the network configuration of PICS. The expected duration of PICS inoperability is approximately 24 to 36 hours. PICS provides monitoring and communications capability for plant data systems including the Emergency Response Data System (ERDS), Safety Parameter Display System (SPDS), Plant Process Computer System (PPCS), Emergency Response Computer Logger (ERCO-1), Meteorological Data link system and the Inadequate Core Cooling Monitor (ICCM). The loss of PICS requires alternate methods, as described in plant procedures, to be used for the above described functions. Therefore, appropriate assessment of plant conditions, notifications and communications can still be made, if required, during the time that PICS is inoperable. This report is being made in accordance with 10 CFR 50.72(b)(3)(xiii) which is any event that results in a major loss of emergency assessment capability, offsite response capability or offsite communications capability. As previously stated, alternate means remain available to assess plant conditions, make notifications and accomplish required communications, as necessary. An additional notification will be provided when PICS operability is restored.
"The NRC Resident Inspector has been notified."
* * * UPDATE FROM RICHARD SWEENEY TO JOE O'HARA AT 1653 ON 7/8/07 * * *
"Engineering change (EC) of PICS continues. Testing of the installed modifications is now in progress. As stated above, alternate means remain available to assess plant conditions, make notifications, and accomplish required communications, as necessary. Testing of the EC and EC turnover is expected to be completed on 07/09/2007. The plant computers, including SPDS, are presently running providing plant data thus are available but not operable."
The licensee notified the NRC Resident Inspector.
