| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - LICENSED MATERIAL RECOVERED AT A LANDFILL
NOTIFICATIONS:
"On December 6, 2013 the PA Department of Environmental Protection (PA DEP) was notified of a radiation alarm at Modern Landfill in York, PA. A health physics consultant for the landfill had responded and determined that two bare molybdenum-99 (Mo-99) generator cores were the cause of the alarm. The Mo-99 generators had their labels intact and noted an activity of 18 curies (Ci) on 10/29/2013 and 11/06/2013. Expiration dates were 11/12/2013 and 11/19/2013 respectively. Per 10 CFR 20.2201, decay correcting the activity would prompt a 30-day report per 10 CFR 22.2201(a)(ii); however, after further investigation and discussion with the licensee, a conservative (immediate) report per 10CFR 20.2201(a)(i) may be required.
EVENT DESCRIPTION:
"The December 6th initial notification to the PA DEP/BRP was due to a load of solid waste possibly containing Mo-99, versus Tc-99m which is often found to set off landfill radiation alarms. Upon off-loading the waste and discovery of two bare Mo-99 generator cores and investigation the following week, the serial number on each of the Mo-99 generator labels revealed they were from a Pennsylvania nuclear pharmacy licensee, Cardinal Health (C. H.), PA-0385. A reactive inspection was initiated. The RSO for C.H. concluded that the generators may have been stolen after their expiration date, and thus would involve a decayed activity of 510 mCi. This is greater than 1,000 times the quantity specified in 10 CFR 20 Appendix C for Mo-99 (that is, greater than 100 mCi). PA DEP/BRP is expecting the licensee to assess the range of whole body and extremity doses to the individual(s) that disassembled these Mo-99 generators using conservative bounding assumptions. No one has admitted to the removal of the Mo-99 from the C.H. facility.
CAUSE OF THE EVENT:
"Possible theft as a crime of opportunity for scrap lead shielding.
ACTIONS:
"A reactive inspection by the PA DEP Regional Office has already occurred and further evaluation of the potential individual radiation exposure and needed corrective actions are ongoing."
PA Event Report ID No: PA130029
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.

"At 1050 EST on Tuesday, December 31, the Cook Nuclear Plant (CNP) Technical Support Center (TSC) air conditioning and charcoal filtration systems will be removed from service for scheduled maintenance.
"Under certain accidents conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary.
"TSC ventilation system maintenance and post maintenance testing is scheduled to be completed by 1600 EST on December 31, 2013.
"The licensee has notified the NRC Resident Inspector.
"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to the loss of an emergency response facility."

"Prairie Island Unit 2 is currently in Mode 3 with RCS [Reactor Coolant System] at Tave 547 degrees and 2235 psig and preparing for reactor startup following steam generator replacement outage 2R28.
"At 0933 December 31, 2013 it was discovered that multiple upper lateral support shims and bumpers were removed from both 21 and 22 steam generators. This resulted in both loops being declared inoperable and entry into Tech. Spec. [Technical Specification] LCO [Limiting Condition of Operation] 3.4.5 Condition D. It also placed the Unit 2 Reactor Coolant System in an unanalyzed condition for Seismic and LOCA analyses and required this 8 hour report under 10 CFR 50.72(b)(3)(ii)(B).
"During this condition both reactor coolant loops were in operation, adequately removing decay heat and keeping Prairie Island in a safe condition.
"Tech Spec [LCO] 3.4.5 Condition D requires 3 immediate actions: 1. Place the rod control system in a condition incapable of rod withdrawal; action is completed. 2. Suspend operations that would cause introduction into the RCS, coolant with boron concentration less than required to meet shutdown margin; action is completed. 3. Initiate action to restore one RCS loop to operable status and operation; action was immediately initiated.
"Actions have been initiated to reinstall all shims and bumpers in both steam generators. Once these actions are completed and verified the unanalyzed condition will be corrected and Technical Specification [LCO] 3.4.5 Condition D will be exited. These actions are expected to be completed by 1600 on December 31, 2013."

"At 11:00 EST on Wednesday, January 1, 2014, during a scheduled functional test of the Cook Nuclear Plant (CNP) Technical Support Center (TSC) ventilation system, the following two dampers failed to properly open when the system was placed in emergency mode (ventilation flow directed through the emergency filtration unit):
12-HV-TSC-SD-5, TSC Ventilation Emergency Flow To & From Air Conditioner 12-HV-TSC-AC-1 Volume Damper
12-HV-TSC-SD-7, TSC Ventilation Emergency Filtration Unit 12-HV-TSC-FIL Inlet Volume Damper
"The TSC ventilation system is therefore non-functional. This notification is being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to an emergency response facility being non-functional. Repair activities are in progress for repair of the two dampers.
"Under certain accident conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary.
"The licensee has notified the NRC Resident Inspector."

After repairs were completed, the TSC was restored to service at 0130 EST on 1/2/14.
