AGREEMENT STATE REPORT OF TROXLER GAUGE RUN OVER BY A TRUCK
The Maryland Department of Environment Radiological Health Program reported that a Troxler moisture density gauge (Model 3430) was run over by a dump truck at a construction site in Prince Georges county (near the intersection of highway 410 and 295). The gauge contained an 8 milliCurie Cs-137 and 40 milliCurie Am-241/Be source. A representative of the Maryland Radiological Health Program responded to the scene and conducted a test for leakage and contamination. The gauge source was determined to be undamaged and in the shielded position. The gauge was packaged for transport and will be sent to the Troxler repair facility.

REACTOR SCRAM AND ECCS INJECTION FOLLOWING OPENING OF TURBINE BYPASS VALVES
"At approximately 04:55 on December 22, 2004, Unit 2 experienced a malfunction of Electro-Hydraulic Control (EHC) system resulting in opening of main turbine bypass valves and resultant loss of reactor pressure. The reactor automatically shutdown on RPS with the completion of a Group I isolation signal (Reactor pressure 850 prig and Reactor mode switch in RUN) resulting in a closure of the Main Steam Isolation Valves (MSIVs). Reactor level lowered to (ECCS) initiation set-point of -48 inches and High Pressure Coolant Injection (HPCI) system and Reactor Core Isolation Coolant (RCIC) system automatically initiated and restored level. When reactor level lowered below the 1 inch set-point, Group II and III Primary Containment Isolation System (PCIS) signals initiated. All Unit parameters are stable and RPS/PCIS/ECCS systems performed as designed. MSIVs remain closed. Reactor level and pressure are stable with HPCI and RCIC systems in control. Group I, II, and III isolations have been reset. The EHC malfunction is presently under investigation by Station Management."
All systems functioned as required. The reactor water level is now at 23 inches and stable and the licensee is conducting a slow depressurization to Mode 4 to investigate the EHC system malfunction. The level transients experience during the scram would be expected with the closure of the MSIVs.
The licensee has notified the NRC Resident Inspector.

DAMAGED HUMBOLDT MOISTURE DENSITY GAUGE.
Representative of SCI Engineering located in St. Charles, MO reported the following incident:
At approximately 1030 CST at a commercial job site in Warrenton, MO., a caterpillar truck ran over a Humboldt Model # 5100C moisture density gauge. The Humboldt case was cracked. The area around the damaged gauge has been roped off (50 feet from the gauge). The licensee did not know if the source rod had been broken off. R. M. Wester & Assoc. should be arriving shortly to take surveys and then take appropriate action based on their survey results. The gauge contains 11 millicuries of Cesium-137 and 40 millicuries of Am-241/Be. As far as the licensee knows there is no release. Warrenton is located about 30 miles West of St. Louis off of Interstate Highway 70.
* * * Update at 1447 EST on 12/22/04 by William Guerdan to MacKinnon * * *
R. M. Wester completed surveys and the results of the surveys are: no leaks and no contamination of the gauge. Both sources are intact and the area around the gauge is clean. The vehicle that ran over the gauge is also clean. R. M. Wester & Assoc. have taken possession of the gauge and they will take back to their St. Peter, Mo. office and perform a leak test of the gauge. Leak test of the gauge should be completed by the close of business today, 12/22/04.
R3DO (L.Kozak) and NMSS (S. Wastler) notified.

AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE DENSITY GAUGE
The following information was received via Email:
"Licensee called to report one of their Troxler 3430 gauges (serial number 23691- 8 mCi Cs-137 / 40 mCi Am 241/Be) had been stolen along with the vehicle it was in. The gauge was reported to be locked in the enclosed SUV which was parked outside of the Riverside office this morning [12/22/04]. The gauge user came out to his vehicle at about 0445, shortly after transferring the gauge from the storage facility to his vehicle, and discovered the vehicle had been stolen. A report was filed with the Riverside Police Department (P304357039)."
* * * UPDATE FROM R GREGER TO W GOTT AT 1419 ON 12/23/04 * * *
"This gauge was recovered approximately noon yesterday [12/22/04], the same day it was stolen, when the stolen truck was recovered. The gauge was still in its transportation case in the truck and apparently had not been accessed."
Notified NMSS (T Essig), R4DO (Spitzberg), TAS (J Foster) (email), and faxed to Mexico.

RPS ACTUATION DUE TO STEAM GENERATOR LOW LEVEL SIGNAL
"Unit 2 reactor trip due to 2C steam generator LO-2 reactor protection signal. Auxiliary Feed Water actuated as expected. No additional malfunctions or unexpected plant response. Cause of LO-2 steam generator reactor protection signal under investigation.
"This is a 4 hour notification of an RPS actuation per 10 CFR 50.72(b)(2)(iv)(B). The 8 hour notification of Auxiliary Feed Water system actuation per 10 CFR 50.72 (b)(3)(iv)(B) is being made under this same telephone call."
The licensee notified the NRC Resident Inspector. All control rods fully inserted. Decay heat is being removed to the main condenser via the turbine by-pass valves. The electrical grid is stable.
* * * UPDATE FROM F. EHRHARDT TO M. RIPLEY 15:55 ET 12/22/04 * * *
The licensee has determined that the RPS and Auxiliary Feed Water actuations were the result of an actual low level in the 2C steam generator. The cause of the low level is under investigation. The NRC Resident Inspector was informed. Notified R3 DO (L. Kozak).
