The licensee was performing maintenance on "D" Steam Generator Low Level bistables when 4 (four) out of 8 (eight) trip control breakers opened possibly due to a 24 V DC power supply transient to 2 (two) of 4 (four) logic matrix relays. The reactor trip logic was verified to be functional and capable of processing valid reactor trip signals. The actuation was invalid as no plant transient occurred and no process variable was exceeded which would otherwise have required a reactor trip.
The licensee notified the State and the NRC Resident Inspector.
* * * RETRACTION ON 08/14/06 AT 0947 ET BY M. EWER TO MACKINNON * * *
"Upon further review, the initial notification of this event is determined to have been conservative. A review of NUREG 1022, Rev. 2, 'Event Reporting Guidelines, 10 CFR 50.72 and 50.73,' as well as the supporting comments in the notice of final rulemaking for changes to 10 CFR Parts 50 and 72 contained in the Federal Register on October 25, 2000, indicates that these documents stress the need for reporting of system actuations. As stated in NUREG 1022, 'actuation of multichannel actuation systems is defined as actuation of enough channels to complete the minimum actuation logic. Therefore, single channel actuation logic,' Per the final rulemaking, 'the principal reason for reporting an actuation of one of these systems is that it is indicative of an unplanned plant transient that the NRC needs to evaluate to determine if action is necessary to address a safety problem.'
"In the event described in CR-06-06880, a portion of the RPS actuation sufficiently to cause four of the eight TCBs to open (i.e, a half trip), but not enough channels actuated to complete the minimum actuation logic for RPS (i.e, insufficient channels to fulfill the safety function of the RPS to deenergized the control rod drive mechanisms to shutdown the reactor). There was no unplanned plant transient as a result of the half trip.
"Determination
"Based on the above assessment, this condition in NOT reportable per 10 CFR 50.73(a)(2)(iv)(A) as an actuation of any of the systems listed in paragraph 10 CFR 50.73(a)(2)(iv)(B).
"Accordingly, the report of a 4 hour non-emergency event under 10 CFR 50.72(b)(2)(iv)(b) for a half RPS trip actuation should be withdrawn."
R1DO (Lorson) notified.

The State provided the following information via e-mail:
"At about 8:45 am, [DELETED] with California OES notified RHB that he had received a call regarding a damaged moisture-density gauge. [DELETED], Alternate RSO for Southland Geotechnical (also dba Landmark Consultants), called to report that a Troxler, Model 3430 moisture-density gauge (S/N 29144), with a nominal 8 mCi Cs-137 and a nominal 40 mCi Am-241 source was run over by a loader at a temporary job-site in Heber, CA. The guide bar was broken, but the source rod was not. They were able to fully retract the source, but could not lock it in the shielded position. They took a leak test of the source, which is being analyzed, and they used duct tape to maintain the source in the shielded position. The source is currently secured in its case at the authorized, permanent storage location. After the results of the leak test are returned, if it is negative, the gauge will be returned to Troxler for repair." |

"The truck was found by police at 4 pm [PDT], August 9. It had been abandoned in a strip-mall parking lot near Everett. DOH staff were at the scene, making measurements and assured radiation safety for police and fire personnel during the recovery effort. It appears the dark room had not been entered. The radiography device was still in its stowed position. After the police had finished conducting their criminal investigation at the scene, the truck and device were returned to WeldSonix IR personnel.
DOH staff are continuing to investigate the incident. Corrective actions are to be determined."

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy. |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT INVOLVING A STOLEN TROXLER MOISTURE DENSITY GAUGE
The State provided the following information via email:
"A Moister density gauge ( Troxler 3440 - Ser # 19048) was stolen on 8/9/06 at about 1600 in El Paso Texas. The gauge was stolen from the storage area at the facility. There appears to be no signs of forced entry to the area. A Police report was filed. The EPPD was to coordinate with the jurisdictional police department to visit the prime suspect (former PSI employee) yesterday evening (8/9/06). Locks at the facility are being changed. The local scrap yards and the Texas Association of Pawnbrokers have been notified. The source information is 1 Cs-137 source serial # 50-8685 8 mCi, and AmBe serial # 4714512 40 mCi. The licensee will provide a written report as soon as all the information is gathered."
Texas incident # I - 8354
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. |

"On Monday, August 14, 2006, Southern California Edison (SCE) made a voluntary communication to California State and Local government agencies regarding water samples taken during on-going Unit 1 decommissioning activities. During the week of August 7, 2006, water samples were found to have tritium levels ranging from 50,000 -- 330,000 picoCuries/liter. No permits were violated.
"It was thought that the contamination may be attributed to historical events during Unit 1 operation (Unit 1 ceased commercial operation in 1992). SCE is investigating the source of the tritium and, as part of decommissioning, will remediate the contamination. The groundwater beneath SONGS is not a source of drinking water.
"The NRC Resident Inspectors have been notified of this occurrence and will be provided with a copy of this report." | |
