AGREEMENT STATE REPORT - LOST/MISSING LICENSED MATERIAL

The following information was received from the State of Tennessee via email:

"On June 11, 2013, RbM Services, LLC contacted the [Tennessee] Division of Radiological Health to report that on May 29, 2013, 6 Bracco Diagnostics Inc. Rubidium Generators (Sr-82/Sr-85 Solid Strontium Mixture) were shipped to Los Alamos National Labs in Los Alamos, NM via Common Carrier.

"On May 31, 2013, it was discovered that two of the shipments of generators (78.78 mCi of Sr-85 and 49.37 mCi of Sr-85) had not arrived in Los Alamos. The tracking numbers showed the 2 shipments were still in Memphis, TN. On June 3, 2013, [the] Common Carrier's tracking update via phone stated the 2 shipments were enroute to Los Alamo's zip code.

"On June 4th, after learning the shipment had not been delivered, RbM contacted [the] Common Carrier and Bracco, the manufacturer of the generators. As of June 5th, [the] Common Carrier informed RbM that an extensive search for the packages was being made and a trace had been placed on the shipment.

"On June 6th, RbM contacted [the] Common Carrier and instructed them to contact Los Alamos National Labs to see if the shipment was delivered; Los Alamos confirmed those 2 shipments had not arrived.

"On June 10th, [the] Common Carrier did not have any additional information and advised RbM to contact their regulatory authority [Tennessee Division of Radiological Health]."

Event Report ID No. TN-13-104

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.

AGREEMENT STATE REPORT - FAILURE OF GAUGE SHUTTERS TO OPERATE

"On June 13, 2013, the licensee notified the Agency [State of Texas] that after completing maintenance on cables on Hoppers that one of the retest was to operate shutters on all nuclear gauges. The failures were identified on June 12, 2013. Eight gauge shutters failed to operate. The shutters are on Thermo Fisher Model #5197 gauges each containing 100 mCi of Cesium-137. The licensee stated that open is the normal operating position for the shutter and the gauge does not pose an exposure risk to any individual. The sources are not accessible to the general public or workers in the area. The licensee stated that a service provider will most likely remove and possible replace the gauges. The gauges have been in operation for approximately 30 years. Additional information will be provided as it is received in accordance with SA 300."

LOSS OF RADWASTE / REACTOR BUILDING VENT GASEOUS EFFLUENT RADIATION MONITORING CAPABILITY

"At 1227 EDT on June 17, 2013, Nine Mile Point Unit 2 determined that the Radwaste / Reactor Building vent gaseous effluent radiation monitor had failed its source check and was, therefore, non-functional.

"This radiation monitor is necessary for accident assessment and is credited for Emergency Action Level (EAL) classification. The inability to classify an EAL due to the out-of-service Radwaste / Reactor Building vent gaseous effluent monitor is considered a loss of emergency assessment capability and is reportable per 10CFR50.72(b)(3)(xiii).

"Troubleshooting is currently in progress. The expected out-of-service time is unknown at this time. Compensatory actions are in place to take and analyze periodic grab samples in accordance with the Offsite Dose Calculation Manual.

"The NRC Resident Inspector has been notified."

* * * UPDATE FROM DANIEL CIFONELLI TO JOHN SHOEMAKER ON 06/20/13 AT 1300 EDT * * *

"The Radwaste/Reactor Building vent gaseous effluent radiation monitor has been repaired and was returned to service at 0330 [EDT] on June 20, 2013, thereby restoring emergency assessment capability.

"The NRC Resident Inspector has been notified"

The licensee will notify the state.

SULFURIC ACID SPILL REQUIRING OFFSITE NOTIFICATION

"In the owner controlled area, the plant has a tank of sulfuric acid (93% concentration, UN # 1830) for chemical control of the Circulating Water system used in the non-safety related electrical power production portion of the plant.

"At 0600 [CDT], a routine inspection of the tank found acid within the berm surrounding the tank. A leak was discovered in the berm and sulfuric acid leaked onto the surrounding area and nearby drainage ditch. The quantity of leaked acid has been estimated to be 120 gallons. The source of the leak has been determined to be a pipe on the tank and it has been isolated with a closed valve. The tank level has been stable for 4 hours. The leaked acid is contained within approximately 70 linear feet of the [limestone] ditch and has not left the site. On-site operations and chemistry personnel are neutralizing the acid with soda ash and a tanker truck was contracted to arrive on site this morning to empty the acid tank contents until a repair can be accomplished."

The leak was discovered at 0600 and isolated about 0630 CDT.

The licensee notified the NRC Resident Inspector.

TECHNICAL SUPPORT CENTER VENTILATION REMOVED FROM SERVICE FOR MAINTENANCE

"On June 20, 2013 at 1118 CDT, Byron Station removed part of the Technical Support Center (TSC) ventilation (i.e., 0VV23C) system from service to facilitate necessary maintenance on the supply fan. This work is expected to last approximately 2 hours. This maintenance affects the ability of the TSC ventilation to maintain adequate habitability during the duration of an emergency. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures. If the TSC becomes uninhabitable, the Station Emergency Director will relocate the TSC staff to an alternate TSC location in accordance with applicable procedures.

"This notification is being made in accordance with 10CFR50.72(b)(3)(xiii) due to the potential loss of an emergency response facility because of the unavailability of the ventilation system. An update will be provided once the TSC ventilation has been restored to normal operation.

"The NRC Resident Inspector has been notified [by the Licensee]."

* * * UPDATE FROM NICK CRAWFORD TO JOHN SHOEMAKER ON 6/20/13 AT 1635 EDT * * *

Maintenance has been completed and the TSC ventilation system has be restored to service.

The licensee will notify the NRC Resident Inspector.
