ENS 5143229 September 2015 14:56:00On 9/29/15 at 1020 EDT, the 'B' train of Standby Gas Treatment System was declared inoperable for planned testing. On 9/29/15 at 1030 EDT, during performance of a surveillance on Unit 1 Reactor Pressure Vessel water level instrumentation, one channel was found to not meet acceptance criteria. The failed level channel is part of the initiation logic for the 'A' train of Standby Gas Treatment. This resulted in a loss of safety function for the Standby Gas Treatment System. On 9/29/15 at 1145 EDT, the 'B' train of Standby Gas Treatment was restored to operable by restoring from the planned testing. This event is being reported under 10 CFR 50.72(b)(3)(v)(c) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. The NRC Resident Inspector has been informed.
ENS 5142525 September 2015 12:09:00On September 25, 2015 at roughly 0430 EDT, four employees were in the work area when high temperature water and steam released from a wash operation in the Final Assembly Area. The cause of the water/steam release is unknown at this time, and a comprehensive investigation is underway. The area is in a safe, shutdown state, and is roped off to preserve the scene. The event did not involve any special nuclear material or contamination and is classified as an industrial safety incident. Three of the four employees were affected by the high temperature water/steam and were transported by ambulance to the hospital for treatment. This concurrent report is being made under Paragraph c of 10 CFR 70, Appendix A because in-patient hospitalization requires a 24 hour report to the South Carolina Department of Labor. The licensee will notify NRC Region 2.
ENS 510578 May 2015 11:02:00On May 7, 2015, at 1515 hours, B&W NOG-L Security management determined alcohol had been inadvertently introduced into the Protected Area through the shipping and receiving process. 10 CFR 26.719(b)(1) requires that the licensee report to the Operations Center within 24 hours of discovery, the use, sale distribution, possession, or presence of illegal drugs, or the consumption or presence of alcohol within a protected area. The item in question was a six pack of bottled beer which was part of a box of promotional items personally delivered by a sales representative from Graybar Electric. The B&W employee addressee first became aware of the package through an email and voicemail left by the salesman advising of a package delivery and indicating the presence of alcohol in the package. The B&W employee immediately contacted Shipping and Receiving management at approximately 1300 hrs. in an effort to intercept the package before delivery; however the package had already been processed into the Protected Area. Shipping and Receiving Management contacted the delivery driver via radio and instructed the driver not to deliver the package. The delivery driver separated the package from the delivery items. The package was removed from the Protected Area and returned to the Shipping and Receiving Manager located in the Owner Controlled Area at approximately 1500 hrs. The package was returned unopened. B&W Security Management was notified of the incident at approximately 1515 hrs. All items processed through Shipping and Receiving undergo security x-ray inspection. Containers of liquid are commonly processed items and therefore did not create an elevated level of suspicion which would have led to the officers conducting a visual inspection. B&W NOG-L Management will conduct an evaluation of the incident to include root cause analysis and corrective actions to prevent recurrence. The NRC Resident Inspector has been informed.
ENS 510467 May 2015 07:11:00At 0700 on 5/7/15, Indian Point Unit 3 commenced a shutdown due to the inability to isolate a steam leak on a feedwater instrument line. Offsite power is available. Indian Point Unit 2 is unaffected and remains in Mode 1 at 100% power. The NRC Resident Inspector, the NYISO (New York Independent System Operator), and NY Public State Commission have been notified.
ENS 510425 May 2015 10:44:00Per 10 CFR 20.1906(d)(1), (the Veterans Health Administration (VHA) is) reporting receipt of a package of radioactive material with removable surface contamination on the outside of the package greater than NRC reporting limits. The package was received today (May 5, 2015) and surveyed for contamination around 0615 CDT by Captain James A. Lovell Federal Health Care Center, North Chicago, Illinois. The health care center holds permit number 12-10057-04 issued by VHA per the MML (Master Materials License). Wipe tests performed on the external surface of the package indicated a removable contamination level of 690 dpm/cm2 as compared to the regulatory reporting limit of 240 dpm/cm2 for beta-gamma emitters. The package contained five unit dosages of Technetium-99m (about 144 millicuries total) and was shipped and delivered by Triad Isotopes in Elk Grove, Illinois. The nuclear medicine technologist who surveyed the package immediately notified, by telephone, the Pharmacy Manager at Triad Isotopes about the contaminated package. The exterior of the package was able to be decontaminated by the nuclear medicine technologist to levels below reporting limits by performing successive wipes on the surface. The inner packaging materials and dosage containers were surveyed and no contamination was identified such that the dosages were not impacted. There was no spread of contamination at the health care center from the package. The contaminated materials have been isolated in a restricted area at the health care center and will be held for decay. Veterans Health Administration (T. Huston) has also notified NRC Region III (K. Null) by telephone of this event.
ENS 510487 May 2015 09:46:00A consolidated package was shipped to New York on April 7. When the shipment arrived it was missing one of the packages within the consolidated shipping container. At the time of shipment, the package contained 12.7 mCi of In-111 (half-life 2.8 days). The package was a UN 2915 Type A with a 0.1 TI (transportation index) and a weight of 3 lbs. An investigation was conducted with the common carrier. The package was not located. It was declared lost on April 21. 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.

They were in the process of conducting an inspection and leak test of the device when it was discovered. The last time the shutter was cycled was last year. The RSO reports there is no over exposure of personnel, no leaks. The location of device prohibits access to personnel so there is no chance of accidental exposure. The area has been posted and a work order has been submitted to replace/repair the device. Florida Incident Number: FL15-035
ENS 5099620 April 2015 16:43:00

The following was received from the State of Louisiana via email: A radiography inspection was being performed on a Central Testing crew at the Tri-7 facility in Sulphur, LA. At a point during the inspection, the inspector requested that the crew demonstrate a misconnect/disconnect test on the camera and drive cables in use. The crew stated that the equipment had passed the test before the equipment was put into service for the day. However, during the demonstration, the 'control assembly' on the crankout set functioned in a test failure mode. The control assembly easily slipped into position without the drive cable being attached to the source assembly, 'pigtail.' With this failure, the RSO was contacted and an additional set of crankouts were brought to the jobsite. The crankout was evaluated and it was determined that the control assembly is what failed during the test. The control assembly was replaced on the crankout and it corrected the misconnect/disconnect test failure. This test is to be performed on the equipment daily with use. This is a requirement of LA Radioactive Material License LA-2393-L01A, Condition # 16.

The exposure device was a SPEC Model 150 camera, S/N 1057, loaded with a 63 Ci Ir-192 source, SPEC Model G-60. The associated equipment was manufactured by SPEC, crankout and control assembly, with unknown model and s/ns. When the equipment was replaced, the radiography crew was allowed to resume their work. LA Event Report ID: LA 15-0004

ENS 5087510 March 2015 12:28:00The air monitoring vacuum pumps were disabled for approximately 20 minutes. Due to an unplanned power outage, the soft water supply to the air monitoring vacuum pump seals on the 2nd floor of the Feed Materials Building (FMB) was lost. These pumps provide vacuum for the stack monitoring and personnel area monitoring systems in the FMB. The secondary and tertiary water supplies to the pumps were not available when needed. This caused the vacuum pumps to be shut down until a temporary water supply could be established. A temporary water supply was reestablished to the pump seals. The pumps were restored to service at approximately 1520 CDT on 03/09/2015. The licensee has contacted NRC Region II inspector David Hartland regarding this event.
ENS 508572 March 2015 18:31:00On March 2, 2015, Southern Nuclear Operating Company (SNC) had a non-licensed supervisory contractor employee confirmed positive result for alcohol during a fitness-for-duty test. The contractor employee's unescorted access to the plant has been terminated. The NRC Senior Resident Inspector has been informed.
ENS 5085227 February 2015 16:10:00At 1518 EST on Feb 27, 2015, the Perry Shift Manager received notice from the Radiation Protection group that an Exclusive Use closed transport vehicle arrived on site exceeding the 10 CFR 71.47 radiation levels on contact with a box on the vehicle. The truck that arrived had two boxes containing four rebuilt control rod drive mechanisms to be used during the Perry refueling outage. One of the boxes had a contact dose reading of 1290 MR/HR. This is above the 1000 MR/HR limit as noted in 10 CFR 71.47. No other limits were exceeded on the exterior of the vehicle. Specifically, the cab of the truck was reading 0.1 MR/HR which is less than the 2 MR/HR limit. Also at 2 meters around the truck, the highest level reading was 1.2 MR/HR which is below the 10 MR/HR (limit). Also on direct contact with the outside of the vehicle, the highest reading was 30 MR/HR, which is below the 200 MR/HR limit. The Site Radiation Protection Shipping Coordinator contacted the shipping organization of this finding at Perry. This was the Director of Operations of Energy Solutions in Memphis, Tennessee. The box was taken into the Perry Fuel Handling Building and is posted per the Perry Radiation Control Program. The vehicle is parked outside the Fuel Handling Building and is being controlled. The NRC Resident Inspector has been informed.

ENS 5085126 February 2015 16:39:00On February 26, 2015, at 1511 EST, with Unit 1 operating at 95% power in an end of cycle coastdown, the 'B' Main Feedwater Reg Valve failed closed which resulted in a Unit 1 automatic reactor trip due to 'B' Steam Generator low/low level. The operations crew entered the reactor trip procedure and stabilized Unit 1 in Mode 3 at normal operating pressure and temperature. All control rods fully inserted into the core following the reactor trip. This reactor protection system actuation is reportable per 10CFR50.72(b)(2)(iv)(B). The Auxiliary Feedwater pumps actuated as designed as a result of the reactor trip and provided makeup flow to the steam generators. The automatic start of the Auxiliary Feedwater system is reportable per 10CFR50.72(b)(3)(iv)(A) for the valid actuation of an ESF system. The Auxiliary Feedwater pumps were subsequently secured and returned to automatic. Decay heat is being removed by the condenser steam dump system. Unit 1 is in a normal shutdown electrical lineup. The NRC Resident Inspectors have been notified and are in the Control Room. The Louisa County Administrator will be notified.
ENS 5090219 March 2015 10:39:00A Mo-Tc Generator was sent to Baptist Hospital in Miami, Florida. The generator was used for approximately 2 weeks before being shipped back on 1/18/14. It was picked up by the common carrier on 1/19/14. The Mo-Tc generator did not make it back to the Mallinckrodt facility. A search was initiated at the Mallinckrodt facility and Baptist Hospital. When the Mo-Tc generator could not be located, it was declared missing on 2/26/15. The generator is approximately 65 lbs. total and contains 8.1 mCi of depleted uranium-238. The shield was stamped with the number 2116. 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.

ENS 5100322 April 2015 14:18:00On February 24, 2015, at approximately 1702 CDT, while the plant was in cold shutdown, power was lost on the Division 1 reactor protection system (RPS) bus. This event resulted in the automatic closure of the Division 1 primary containment isolation valves in the residual heat removal (RHR) and reactor water cleanup systems. Additionally, the primary containment atmospheric monitoring system automatically actuated, and ventilation systems in the fuel building, auxiliary building, and control building shifted to emergency mode. The closure of the isolation valves in the residual heat removal system caused an automatic trip of the 'A' RHR pump, which had been in the shutdown cooling alignment. The equipment response to the isolation signal was as expected. This event is being reported in accordance with 10 CFR 50.73(a)(1) as an invalid actuation of the Division 1 primary containment isolation system. The isolation was promptly diagnosed as having resulted from a trip of the output breaker of the RPS motor generator (MG) set 'A,' and not from a valid signal. Operators implemented the appropriate response procedures to align power to the bus via the alternate source, and began restoring the affected systems. The 'A' RHR pump was re-started within twelve minutes, during which time coolant temperature increased approximately seven degrees to a maximum of approximately 100F. Other affected systems were restored over the next few hours. The causal analysis concluded that the MG set output breaker tripped due to an overly conservative setpoint on the overvoltage trip relay. The low trip setpoint was a latent condition that had existed since the output voltage was raised in 1988 at the recommendation of the vendor, but at which time the trip setpoint was not changed. To correct this condition, the MG overvoltage trip setpoint was raised to restore adequate operating margin to the normal MG output voltage. At the time of the event, the plant was in MODE 5 with the reactor cavity flooded to greater than 23 feet above the vessel flange. The shutdown cooling system was promptly restored to service. This event was of minimal safety significance to the health and safety of employees and the public. The licensee has notified the NRC Resident Inspector.
ENS 507999 February 2015 17:17:00(The licensee) has discovered a possible assembly error that may result in compromising the capability to isolate the solenoid housing internals from a LOCA environment on some of our solenoid valve models that use grafoil packing for sealing the NEMA 4 enclosure. We are in the process of identifying the valve models affected and will notify all customers affected. Description of Defect/Non-Compliance: As noted on MRR997W the packing ring which seals the solenoid on valve model V526-5631-36 used in Qualification and Production were not matched to the procedure invoked on valve drawing.
ENS 507822 February 2015 16:54:00At 2/2/15, at approximately 0919 EST, a non-licensed employee supervisor had a confirmed positive for alcohol during a random fitness-for-duty test. Due to the confirmed positive test, the employee's access to the plant has been revoked. The NRC Resident Inspector has been informed.
ENS 5078131 January 2015 18:00:00At 1431 EST on 1/31/15, Oconee Unit 3 was manually tripped due to oscillations in the feedwater system in anticipation of an automatic trip. At 1427 EST, Unit 3 began experiencing small feedwater oscillations. Specifically, 3FDW-32, the 3A main feedwater control valve, appeared to be oscillating with corresponding feedwater flow oscillation. Feedwater oscillations continued to grow in magnitude and at 1431 EST a manual trip was directed by the Unit 3 control room supervisor. The shutdown was orderly and the unit is currently stable and in Mode 3 (Hot Standby). Units 1 and 2 were unaffected by the trip and are currently 100% power (Mode 1). Due to the RPS actuation while critical, this event is being reported as a 4-hour non-emergency per 10CFR50.72(b)(2)(iv)(B). Following the reactor trip, a main steam relief valve (MSRV) failed to reseat as expected. Emergency Operating procedure guidance was utilized to reduce main steam system pressure by approximately 80 psig to reseat the valve (valve reseated at 1506 EST). All of the main steam relief valves are now seated. In addition, the 3B condensate booster pump experienced a mechanical seal leak (approximately 4-5 gpm). The pump was subsequently secured at 1447 EST. All other post trip conditions were normal and all other systems performed as expected. Unit 3 is currently in Mode 3 and stable. All rods fully inserted. Main Feedwater is feeding the steam generators and decay heat is being removed to the Main Condenser. The cause of the trip is under investigation. There is no known primary to secondary leakage. The NRC Resident Inspector has been informed.
ENS 5077930 January 2015 15:42:00The following was received from the State of California via email: On January 30, 2015, a telephone report was made to the (California Department of Public Health) CDPH Director's office that a gauge had been stolen. The person making the report was difficult to understand, but the Director's office was able to ascertain the contact telephone number. Upon receiving notice of the call, a representative from (Radiologic Health Branch) (RHB) immediately called that telephone number (at approximately 1100 PST on January 30, 2015), and spoke with the RSO of Giles Engineering Associates, RML #4592-30. (The RSO) stated that a moisture/density gauge (CPN, MC-1DRP, serial #MD20506575 containing 0.370 GBq of Cs-137 and 1.85 GBq of Am-241) had been stolen from a transport vehicle in front of a Comfort Inn at 1185 Admiral Callahan Lane, Vallejo, CA. The authorized gauge user had left the radioactive gauge chained and locked in the back of his vehicle at approximately 0600 PST and went back inside the Comfort Inn to complete some paper work. When he returned to his vehicle at approximately 0625 PST to go to the worksite, (the authorized gauge user) noticed that the chains had been cut through and that the radioactive gauge had been removed from his vehicle. (The authorized gauge user) contacted the RSO of Giles Engineering Associates, who stated he had attempted to notify Local Law Enforcement officials in Vallejo to report the theft. (The RSO) was directed to fill out a report online as that was the policy of the Vallejo Police Department in regards to all theft cases not involving immediate threats to persons. When (the RSO) receives (the authorized user's) written report and the police report, he will forward them to RHB Brea. (The RSO) will utilize local papers in the Vallejo area to attempt to retrieve the stolen gauge. Additionally he will notify local vendors who service radioactive gauges to be alert for the serial number of the stolen gauge in case it turns up at any of their facilities.

ENS 5045513 September 2014 09:53:00A fire penetration on the Unit 1 reactor building 158 foot elevation was discovered to be degraded such that the associated wall would not meet Appendix R requirements as a 3-hour barrier. In the event of a postulated fire in either of the affected fire areas, separated by the affected penetration, both Unit 1 safe shutdown paths could be compromised. Given this information, the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B). Compensatory measures were established in accordance with the plant's Fire Hazard Analysis (FHA). The presence of the compensatory measures in addition to automatic fire detection in these fire areas ensure that the safe shutdown paths are preserved until the degraded condition can be corrected. Condition Report: 865615 The NRC Resident Inspector has been informed.

This monitor provides indication of release of gaseous radioactivity to the environment. There is not a compensatory measure that will allow timely classification of two Emergency Action Levels when out of service: General Emergency Event RG1.1 and Site Area Emergency Event RS1.1. This results in a loss of emergency assessment Capability while 1R-50 is out of service. This is a reportable condition in accordance with 10 CFR 50.72(b)(3)(xiii). Unit 1 Shield Building ventilation stack is also monitored by radiation monitor 1R-22 that is used for the same purpose in Alert or Unusual Event Emergency classifications. 1R-22 is being monitored and is indicating normal values. There are no radioactive leaks that will impact the Shield Building as evidenced by normal readings on 1R-50 prior to its removal from service. The maintenance is scheduled for ten hours or will continue until the monitor is returned to service. Maintenance will not result in the unplanned release of radioactivity to the environment and will not affect the safe operation of the plant or health and safety of the public.

ENS 5037415 August 2014 17:04:00The following was received from the State of Oklahoma via email: Phillips 66 Co. (OK-07402-12) has reported the failure of the shutter mechanism on one of their fixed gauges. Earlier today the shutter was closed while the licensee collected a leak test sample. The RSO noted that the shutter was difficult to operate. When they returned the shutter handle to the 'open' position, the control room which monitors the gauge readings reported that the readout briefly returned to its normal level, then dropped back to zero when the shutter was supposed to be fully open. Repeated attempts showed that the gauge only operated when the shutter was approximately 75% of the fully 'open' position. The licensee has contacted the gauge manufacturer but they won't be able to supply a replacement for approximately 6 weeks. The licensee has requested permission to leave the gauge in service until a replacement is available. The gauge is installed on a stand pipe 18 feet above ground level in an oil refinery in Ponca City, OK. It is only accessible by catwalk which the RSO is going to cordon off. Material in the gauge is Cs-137, 25 mCi when new in 1993. We(State of OK) have told the RSO they may leave the gauge in operation pending the results of the leak test. If these show the source to be leaking they must immediately remove the gauge from service.

ENS 5028014 July 2014 15:47:00The following was received from the Commonwealth of Kentucky via email: KY RHB (Kentucky Radiation Health Branch) was notified by telephone on 7/11/14 by Todd Ramkey, Corporate RSO at Schnabel Engineering Inc. in Glenn Allen, VA, of the fact that a CPN model MC-1 portable moisture/density gauge had been run over and crushed at a coal slurry impoundment belonging to Long Fork Coal Company in Hatfield, KY. The CPN gauge contained 10 mCi of Cs-137 and 50 mCi of Am-241/Be. Initial surveys performed by the licensee with a RadAlert GM survey instrument indicated the sources were not breached and that there was no contamination on the ground where the incident occurred or on the bulldozer involved. The shattered pieces of the device, including the two sources, were packaged on-site by the licensee into a 55 gallon drum in accordance with guidance provided by the radiation safety staff at Instro-Tek in Raleigh, NC, labeled appropriately and shipped back to the offices of Geo/Environmental Associates, Inc. in Knoxville, TN in a company owned vehicle. The shipment was met by a representative of the TN Division of Radiological Health where follow-on surveys and contamination smears were taken. They also instructed the licensee to send leak test wipes to Instro-Tek for expedited analysis and instructed the licensee to send personal monitoring for those involved in for analysis. A telephone call to RHB from the CRSO at Schnabel on 7/14/14 at approximately 1500 said indicated leak test results from Instro-Tek were less than the 185 Bq limit and that no breach of the sources had occurred. RHB gave the CRSO permission to release the control of the site and the equipment at Long Fork Coal based on these negative leak test results. The CRSO at Schnabel indicated that hardcopies of the leak test results would be provided to both RHB and TN Div. Rad Health as well as the results of personal monitoring for those involved in the incident including transportation of the gauge back to Knoxville. Reporting criteria defined in 902 KAR 100:040, Section 15(2)(b) (10 CFR 30.50(b)(2)).
ENS 5036914 August 2014 17:17:00A patient undergoing High Dose Rate Brachytherapy using Ir-192 was prescribed 700 cGy per fraction and only received 700 cGy to 60% of the planned volume. The patient was scheduled for two treatments. The first treatment was successfully administered to the patient on 6/26/14. When the patient returned for the second treatment on 7/10/14 the HDR afterloader was loaded with the treatment plan for the original treatment instead of the second treatment. This resulted in the patient not receiving the full prescribed treatment. The licensee discovered the problem during an audit when the number of catheters did not match. There are no adverse health effects expected as a result of this treatment. The licensee has contacted the vender to determine a way to remove old treatment plans from the machine to ensure this does not happen in the future. A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
