| Event Text COLORADO AGREEMENT STATE REPORT - LOST SOURCE FROM A TROXLER MOISTURE DENSITY GAUGE
Colorado Department of Public Health and Environment received a report from a licensee, Ground Engineering Consultants, that they had possibly lost a Model 3440 Troxler Moisture Density Gauge containing an 8 milliCurie Am: Be source and an 8 milliCurie Cs-137 source. The technician transporting the gauge failed to properly secure the gauge in the back of his vehicle.
When the technician discovered the gauge missing, he backtracked and found pieces of the gauge on Arapahoe Road in metropolitan Denver. At the time of discovery, the licensee determined that the sources were intact in the shielding base on radiation surveys. Upon further investigation, it was discovered that the Cs-137 source was missing.
The licensee and technicians from the State of Colorado are currently searching the area for the lost source. The State of Colorado will provide an update on the results of the search.
* * * UPDATE FROM STROUD TO CROUCH ON 12/10/04 @ 1744 HRS EST * * *
Colorado Department of Public Health and Environment (CDPHE) informed the Operations Center that attempts to locate the missing source have proven unsuccessful. CDPHE Public Affairs has issued a press release to inform the public of the missing source and how to proceed if the source was found. CDPHE will provide an update to this event as necessary.

On December 10, 2004, (Friday), the Licensee had dispatched operator [deleted], for a job with a Troxler 3440, Serial No. 33733, containing two sealed Special Form sources: 8.0 mCi (nominal) Cs-137, Serial No 750-9391, and 40.0 mCi (nominal) Am-241/Be, Serial No 47-22867. Upon completion of the job the operator was returning to the company office, he decided to stop by the Wal Mart store in Harris County, Texas. Upon returning to his company truck, Ford F150 fleetside, License Plate No. [deleted], he determined that the gauge was missing from the tiedown location. Looking into the bed of the truck he noted that the cable securing the gauge to the truck had been cut and was laying in the bottom of the truck bed near the tailgate, still locked into place. The operator reported the incident to his supervisor and was advised to report the incident to the Harris County Constable's Office - Precinct #4. While he was making the report, Case No 0412101909, the company R.S.O. reported the incident to the Texas Department of State Health Services (DSHS) on-call duty officer. Due to the R.S.O. being at home, he did not have the source Serial Numbers. The source serial numbers were reported to the Agency on Monday afternoon at 1:15 p.m.
Licensee is considering offering a reward and announcing the loss to local media.

On November 4, 2004, at 0917 hours EST, an inadvertent actuation of the left train of the safety injection system was initiated. The invalid actuation occurred during a system surveillance test, when a screwdriver that was being used to lift a lead slipped, causing a short circuit between the terminal being disconnected, and an energized terminal directly in front of it. As a result, all left train safety injection system equipment activated as expected for existing plant conditions.
The resident inspector was notified of this event. |

Issue:
By letter dated October 26, 2004, Electric Power Research Institute (EPRI) notified affected members in accordance with 10 CPR 21.21(b), of a non-conservatism in the [software product of] EPRI Motor Operated Valve Performance Prediction Methodology (PPM), Versions 1.0 through 3.2, to predict total required dynamic torque under compressible flow conditions for actuators for butterfly valves with single disc offset designs. As explained in the error notice, the non-conservatism could be as much as 45 percent. This non-conservatism could potentially jeopardize the design basis operation of associated safety related applications.
Southern Nuclear Company (SNC) subsequently performed an engineering evaluation based on the EPRI notification as it related to Vogtle Electric Generating Plant (VEGP). The assessment did not identify any instances where the PPM had actually been used for such purposes at VEGP.
Corrective Action:
This issue has been entered into the SNC Corrective Action Program. SNC will evaluate the restrictions, adjustments, and recommendations regarding use of the EPRI MOV PPM, Versions 1.0 through 3.2, that were communicated in EPRI PPM Software Error Notice 2004-2. |

"At 10:06 hours, Surry Power Station requested outside assistance from the Commonwealth of Virginia, State Police to remove an unknown device which was found floating in the water near the Surry Power Station Circulating Water Intake facility. The unknown device measures 2 inches in diameter and is approximately 14 inches long. It was marked with the following information: 'white phosphorus - contact military or law enforcement.' It is believed this is not an explosive device but a military flare.
"In addition, notification was made to the Surry County Sheriff department at 10:10 hours.
"The Virginia State Police in turn have notified the Navy EOD at Little Creek for assistance. This is being reported in accordance with 10 CFR50.72, (b) (2) (xi)."

"The oil plug on the HPCI booster pump bearing was discovered to be loose at approximately 2100 [CST] on 12/14/2004. Upon discovery, the plug was re-tightened. The plug may or may not have fallen out had the HPCI system initiated.
"HPCI is operable, but subsequent evaluation has determined this to be reportable because, at the time of discovery, HPCI operation could not be assured. Event investigation is on-going."
