| Event Text AGREEMENT STATE - LOST OR STOLEN TRITIUM ILLUMINATED SIGN
The following was received from the State of Nebraska via facsimile:
"Four signs with 8.5 curies of tritium were installed at Big Red Keno Lottery in 1991 during a remodeling project. The main entrance to the building was moved in about 1993. The original main entrance doorway was closed except for a small door which was not a fire exit. They believe the sign to the original entrance was removed at that time. No one knows where the sign went. After doing an inventory requested by this Agency, the facility discovered the sign missing and we were notified.
"The lost sign is a sealed source, manufactured by Safety Light Corporation, Model Number 880-12-5-12, Serial Number C17089. The probable disposition of the sign is the city landfill.

| Event Text AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE
A Troxler Model 3440 Moisture Density Gauge, S/N 34418 (8 millicurie Cs-137; 40 millicurie Am-241/Be) was stolen from the back of a pickup truck sometime between 2000 PST 11/02/03 and 1200 PST 11/03/03 at an employee's apartment complex in Tualatin, OR. The gauge was locked in its case and the case was chained to the truck at the time of the theft.
The licensee notified the Tualatin, OR police department. The State Dept. of Radiation Protection will be issuing a press release. |

"Inserted a Manual Reactor Scram due to high reactor coolant conductivity. Source of high reactor coolant conductivity is not certain at this time.
"In addition, this report is being made under 50.72(b)(3)(iv)(A), 'Any event or condition that results in valid actuation of any systems listed in paragraph (b)(3)(iv)(B) of this section' due to PCIS groups 2, 3, and 4 being received when reactor water level dropped below 170". All isolations went to completion. The reactor water level drop is normal following a scram from 45% power due to void collapse in the reactor vessel. Reactor water level was restored to normal and the PCIS group isolations were reset.
"The current plan is to cool down the plant and enter Mode 4, plant cool down is being achieved using the RCIC system until the source of the conductivity transient is identified and isolated."
The licensee indicated shortly prior to the scram a coolant chemistry transient was in progress. The limit for reactor coolant conductivity is 5 micro mhos per centimeter and the highest conductivity reading reached was 8 micro mhos per centimeter. The licensee speculates the most likely source of the high conductivity is related to an off service condensate demineralizer. There were no automatic ECCS initiations. No SRVs lifted. All control rods properly inserted.
The licensee notified the NRC Resident Inspector. | |
