| Event Text 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."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - ILLEGAL TRANSFER OF A DEVICE CONTAINING AMERICIUM-241
The following information was receive from the State of Arizona via e-mail:
"On May 16th, 2013, the Agency [Arizona Radiation Regulatory] received notification from the State of Texas that an illegal transfer of a device containing 30 millicuries of Americium-241 occurred on November 19, 2012. The device is a Thermo Niton XLP818 and the device serial number is 6380. The device was shipped from Longview Scrap & Metal, Inc. in Texas to an individual. The address that was given was to a mailbox company where the device was picked up. The company was not able to look up the reference number, due to it being 6+ months since the shipping date.
"The Agency continues to investigate the location of the device."
AZ First Notice: 13-010
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.

"This 60-day telephone notification is being made per the reporting requirements specified in 10CFR50.73(a)(2)(iv)(A) and 10CFR50.73(a)(1) to report an event involving an invalid actuation signal affecting the Auxiliary Feedwater (AFW) and Essential Service Water (ESW) systems.
"Initial conditions on 04/24/2013: refueling outage was in progress, there was no fuel in the reactor vessel (No MODE), a B safety-related train outage was in progress, and the A ESW train was in operation to support cooling of the A train safety-related equipment. Some separation group 2 bistables were in a tripped condition because instrument power bus NN02 was de-energized.
"At approximately 0400 [CDT] on 04/24/2013, Separation Group 4 DC bus NK04 experienced a ground condition. Plant personnel were using a plant procedure to search for the ground. When breaker NK5409 was opened, some unexpected Engineered Safety Features Actuation System (ESFAS) signals occurred. Opening the breaker removed power to the B ESFAS cabinet. With power removed to the B ESFAS cabinet, the circuit cards that generate cross-train trips failed to a tripped condition (thus generating cross-train trip signals) which resulted in some A train ESFAS actuations, in particular, auxiliary feedwater actuations for the A motor-driven and the turbine-driven AFW pumps. Additionally, an AFW Low Suction Pressure (LSP) circuit card tripped, and when combined with the bi-stable that was in a tripped state because bus NN02 was de-energized, the 2-out-of-3 logic was made up, resulting in an auxiliary feedwater LSP actuation. The LSP actuation resulted in the A Train ESW pump receiving a start signal, and the A motor-driven and the turbine-driven AFW pump suction supply valves receiving an actuation signal to transfer the suction supply from the normal source to the ESW system.
"Neither the motor-driven nor the turbine-driven auxiliary feedwater pumps started because they had been properly removed from service earlier in the outage. The A ESW pump was already running. No water was transferred from the ESW system to the AFW system since system tagging had been previously placed to isolate the two systems.
"The actuations were considered invalid because they were caused by opening breaker NK5409 which resulted in loss of power to the B ESFAS cabinet.
"The Senior Resident Inspector was notified." |

"On June 24, 2013, at 0000 EDT, the Technical Support Center (TSC) will be unavailable due to a pre-planned facility upgrade project. The TSC is expected to be restored to operational status on July 1, 2013.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures, and the TSC staff will be located at a preplanned alternate location in accordance with applicable site procedures.
"This notification is being made in accordance with 10CFR 50.72 (b)(3)(xiii) due to the loss of an emergency response facility (ERF). An update will be provided once the TSC has been restored to operational status. The NRC Resident Inspector has been notified."
The upgrades will require structural changes to the TSC. |

"At 2120 PDT, Diablo Canyon Power Plant experienced a loss of the offsite 230 kV startup power source due to an offsite transmission system relay actuation, resulting in valid anticipatory starts of Units 1 and 2 three emergency diesel generators on each unit. All diesels successfully started but were not loaded. All systems operated as designed with no problems observed.
"The 230 kV startup power source is the only offsite power system designed to be immediately available following an accident. However, the safety related onsite emergency diesel system would have provided power to mitigate the consequences of an accident while the 230 kV was unavailable.
"Restoration of the 230 kV offsite power system is in progress."
The licensee will notify the NRC Resident Inspector. |
