"Control Room Emergency Filtration System (CREFS) was declared inoperable at 1812 on 12/8/06 because the W-14A, F-16 Control Room Charcoal Filter Fan tripped during performance of the monthly technical specification surveillance test, TS-9.
"This fan is required to be operable for operability of the CREFS System. This condition is covered by TS 3.7.9, Control Room Emergency Filtration System and both units have entered action condition A, 'CREFS Inoperable' with a required action to 'Restore CREFS to OPERABLE Status' with a completion time of 7 days.
"CREFS is a single train system. Based on the guidance in NUREG-1022 for single train systems that perform safety functions, this condition was determined to be reportable under 10CFR50.72(b)(3)(v), 'Event or Condition That Could Have Prevented Fulfillment of a Safety Function'."
* * * RETRACTION PROVIDED BY VANDERWARF TO KOZAL ON 12/28/06 AT 0952 * * *
"On December 8, 2006, at 22.42 EST, EN 43040 was made by the Point Beach Nuclear Plant in accordance with 10 CFR 50.72(b)(3)(v)(D) as a condition at the time of discovery could have prevented the fulfillment of a system function that is needed to mitigate the consequences of an accident. Control Room Emergency Filtration System (CREFS) fan W-1 4A, F-16 Control Room Charcoal Filter Fan tripped during performance of the monthly Technical Specification surveillance test. CREFS was declared inoperable.
"After further evaluation, it was determined that the safety function of CREFS was not lost. Redundant fan W-14B was operable for the duration of the time fan W-14A was out of service. Single train portions of the system were not affected by the W-1 4A fan trip. Accordingly, this event is not reportable. EN 43040 is, therefore, retracted."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE
"Portable moisture density gauge was stolen along with vehicle (Jeep Cherokee) on night of December 23 or 24 in Las Vegas, Nevada. Gauge loss may have been incidental to theft of vehicle, however company policy was to return gauge to office.
"Troxler model 3411 portable moisture density gauge, s/n 12367"

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 material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - STOLEN AND FOUND TROXLER GAUGE
The State provided the following information via email:
On Sunday Dec 24 the State of Colorado received notification from the licensee of a missing Troxler Model 3430 portable moisture density gauge SN 21961 (Activity: 8 millicuries Cs-137/ 40 millicuries Am-241/Be). The gauge was being used at a job site at Denver International Airport (DIA). The gauge is presumed to have been stolen from the truck outside the field technician's residence in Douglas County and not at DIA. However, this has not been verified.
The time of theft was not determined but is most likely between 8:00 p.m. Fri Dec 22 and 10:00 a.m. Sat Dec 23. The theft was discovered on Saturday Dec 23. The gauge had been properly chained in the back of a pickup truck and both chains had been cut.
The gauge was subsequently discovered intact in an alley in Parker, CO on 12/26/06. The address where the gauge was recovered has not yet been reported by local police.

| Event Text FAILURE OF RADIOGRAPHY CAMERA SOURCE TO FULLY RETRACT
On December 28, 2006, at about 2:30 am local time, while performing a radiography at the pumping facility in Kuparuk, Alaska, the radiography camera source failed to fully retract into the shielded position. The radiographer contacted the Radiation Safety Officer who guided the radiographer in unscrewing the drive cables so that the source was able to be fully retracted. No over-exposures or unplanned exposures occurred.
The camera is a INC Model IR-100. The original source strength of the radiography camera Ir-192 source was 100 curies. Kakivik Asset Management plans to contact the manufacturer of the camera about this occurrence. | |
