PRIMARY-SECONDARY CONTAINMENT PRESSURE DIFFERENTIAL EXCEEDED DUE TO CCP EXHAUST FAN TRIP
"At 1308 CST on January 20, 2016, the main control room received an alarm that the containment building (VR) ventilation system continuous containment purge (CCP) exhaust fan (1VR07CB) tripped. At 1311 CST, primary-to-secondary containment differential pressure was reported to be +0.411 psid. Technical Specification (TS) Limiting Condition for Operation (LCO) 3.6.1.4, Primary Containment Pressure, Action A.1, was entered due to the differential pressure outside the ñ 0.25 psid requirement. At 1327 CST, the CCP B subsystem was restarted and at 1339 CST, primary-to-secondary differential pressure was restored to within the limits of TS 3.6.1.4. The cause of the trip of the 1VR07CB is under investigation.
"This event is reportable under 10 CFR 50.72(b)(3)(ii)(B) as an unanalyzed condition that could have prevented the fulfillment of the primary containment function due to the differential pressure being outside the primary containment initial conditions to ensure that containment pressures remain within design values during a loss of coolant accident. This event is reportable under 10 CFR 50.72(b)(3)(v)(D) as an event or condition that could have prevented the fulfillment of the primary containment function for the same reason.
"The NRC Resident has been notified."

TECHNICAL SUPPORT CENTER OUT OF SERVICE FOR PLANNED PREVENTATIVE MAINTENANCE
"At 0400 CST on Wednesday, January 20, 2016, the Dresden Nuclear Power Station (DNPS) Technical Support Center (TSC) emergency ventilation system will be removed from service for planned maintenance activities. During the maintenance, the TSC Ventilation will be shut down. The TSC air filtration fan and dampers will be non-functional, rendering the TSC HVAC accident mode non-functional. This maintenance is scheduled to minimize out of service time. The planned TSC ventilation outage is scheduled to be completed in approximately 43 hours.
"Contingency plans are in place so that if an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing Emergency Planning (EP) procedures and checklists. If radiological or environmental conditions require TSC facility evacuation during ventilation system restoration; the Station Emergency Director will relocate the TSC staff in accordance with station procedures.
"The NRC Resident Inspector has been notified."
* * * UPDATE AT 0049 EST ON 1/22/16 FROM STEVEN MELL TO JEFF HERRERA * * *
"At 2223 CDT on 1/21/16, Dresden TSC Ventilation was restored. The Dresden TSC Ventilation is functional at this time.

EN Revision Text: AGREEMENT STATE REPORT - LOSS OF PROCESS AUTOMATION BETA GAUGE
The following information was received from the State of Illinois via email:
"The Plant Manager for WINPAK, Inc., in South Chicago Heights, IL, called to report the loss of an ABB Process Automation Model O-2 beta gauge (SN S-1379-T) containing 70 milliCuries of Sr-90. The recent annual general license self inspection revealed some discrepancies in serial numbers and the licensee could not locate this particular device. They believe it to have likely been removed by a local scrap vendor that was on-site. Another possibility is an equipment vendor that was doing some work on site. Both vendors are being contacted as part of the investigation. lEMA [Illinois Emergency Management Agency] staff are at the scrap yard today investigating as well.
"The licensee is continuing to pursue possible leads on the location of the source. lEMA has contacted the manufacturer and they have no records of return but have contacted NDC [does service work under contract to ABB] to see if they retrieved it under contract work. This item will remain open for the required time until the source is recovered or declared lost."
Illinois Item Number: IL15022
* * * UPDATE ON 9/15/23 AT 1406 EDT FROM GARY FORSEE TO ADAM KOZIOL * * *
"On 9/15/23, the device was located at Gaby Iron and Metal in Chicago Heights, IL. The device was heavily damaged with the source exposed. IEMA-OHS responders fabricated shielding and packaged the device for return to the registrant. The registrant will be responsible for proper disposal through an approved vendor. The Agency verified safe and secure storage and will track this matter until disposal verification paperwork is provided."
Notified R3DO (Szwarc) and NMSS (email)
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.
