"During regular power operations at 100% power, DG#1 and DG#2 were declared inoperable due to a common issue associated with indicating lights and the associated sockets installed in various control and auxiliary circuits for both DG's.
"The indicating lights in question are incandescent 120V AC style 120MB bulbs in a socket with a 550 ohm resistor. Style 120MB light bulbs have a failure mechanism where the bulb can cause a short circuit rather than the more common open circuit that is expected when an incandescent bulb filament fails. Cooper originally believed that the socket's integral resistor was sufficient to protect the circuit. In testing performed by an outside laboratory and confirmed on-site using warehouse stock, it was determined that the integral resistor may not have the power dissipation capability to protect the circuit ln which the light and socket are installed if a bulb fails in short circuit.
"This condition resulted in both DG's being declared inoperable at 1340 [CST] due to a loss of reasonable expectation that they would meet their safety function required action to start, load and run to support loads required to mitigate the consequences of an accident. This is a loss of safety function under 10CFR 50.72(b)(3)(v)(D) subject to an 8 hour report.
"As a result of both DG's being inoperable, the Control Room Emergency Filtration System is also inoperable. This is also a loss of safety function subject to an 8 hour report for the same criterion.
"The Senior Resident has been notified."

"CNS is retracting the 8-hour non-emergency notification made on December 19, 2017 at 1340 CST (EN# 53128). Subsequent evaluation concluded a postulated lamp short circuit failure in any of the affected circuits would not impact the ability of the Diesel Generators to perform their safety function and therefore, were operable. With DG operability not affected, the Control Room Emergency Filtration System also remained operable.
"The NRC Resident Inspector has been notified."

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE
The following information was received from the State of California via email:
"On February 6, 2018, at approximately 0845 [PST] [the RSO] of Southwest Calibration & Training, Radioactive Materials License #7567-36, contacted RHB [CA Radiologic Health Branch] Brea concerning the moisture/density gauge, CPN, MC1-DRP, serial #MD40507411 (Cs-137 0.375 GBq, Am-241 1.8 GBq) that had been stolen from a transport vehicle [in] Indio, CA at approximately 0800 [PST]. At 0930 [PST], the RSO of Premier Testing & Inspection, Inc., telephoned RHB Brea to inform that the Authorized User had contacted local law enforcement in Indio, [CA] and was filling out a police report with them. A copy of the theft report will be forwarded to the RHB Brea office to be included as part of this report. [The RSO for Premier Testing & Inspection, Inc.] will contact local newspapers to attempt to retrieve the stolen radioactive gauge as well as notifying local servicing vendors of radioactive gauges to be alert for the serial number of the stolen gauge in case it turns up for service. The investigation will continue to determine if the radioactive gauge can be recovered in a reasonable time frame. This is being reported to the NRC Operations Center as a 24-hour report under 10CFR30.50(b)(2) since the radioactive gauge has been stolen and it cannot be determined what condition the sources are currently in."
5010 NUMBER: 020618
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.

The following was received from the State of Colorado via email:
"Red Rocks Radiation Oncology received a package of Ra-223 Xofigo that had removable contamination levels of approximately 23,000 cpm on the outside of the package. The Ra-223 package was delivered by a Cardinal courier from the Cardinal Health facility in Denver, CO which distributes all radiopharmaceuticals (license CO 392-03 is the Cardinal Health license for general radiopharmaceuticals, they share the same building as CO 1219-01). The inner packaging of the Ra-223 shipment did not evidence removable contamination, nor did the car used to transport the Ra-223 package. Cardinal Health has received the wipes and decontamination waste from Red Rocks Radiation Oncology to attempt to determine the isotope causing the removable contamination. The investigation is currently ongoing."
