AGREEMENT STATE REPORT - MISDELIVERY OF A RADIOACTIVE SOURCE

The following information was received from the State of Nevada by email:

[A Common Carrier] misdelivered an Ir-192 source for 645 North Arlington Avenue, Suite 120, Reno, NV 89503. The address was correct, but the source was inadvertently delivered to the Main Hospital receiving at 235 West Sixth Street, Reno, NV 89503. The source bucket was then delivered to the Radiation Safety Officer (RSO) - at the correct address. Once received by the RSO, the delivering employee was contacted and questioned
about length of contact and it was estimated that 2 mrem of dose was received for 10 minutes of contact. The employee as well as the Director for the receiving department were contacted and told to refuse shipment of anything with a radioactive label and to call the RSO immediately. The shipper (Varian) was contacted and they filed a formal complaint with [the Common Carrier].

Nevada Event: NV140011

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL

Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

AGREEMENT STATE REPORT - RECOVERY OF TWO MOISTURE DENSITY GAUGES BY AN ARIZONA LICENSEE

The following information was provided by the State of Arizona via email:

"Date: May 19, 2014
"Time: 2:30 PM (MST)

"First Notice: 14-012

"Arizona Licensee: N/A
"License No.: N/A

"On May 15, 2014, the [Arizona Radiation Regulatory] Agency was contacted by a licensee who stated that he was called about the disposal of a nuclear density gauge. The caller stated that they were not licensed and did not want to go to the regulatory agency but needed to get rid of the gauge. The caller also stated that if [the licensee] did not take the gauge, he would take it to a dumpster or leave it out in the desert. [The licensee] contacted the Agency on the afternoon of the 15th to discuss the situation. [The licensee] was contacted on the 16th and subsequently met the unknown caller and picked up the gauge. The gauge was brought to the Agency, where it was leak tested and secured.

"The depth moisture gauge came in two different wood boxes. The first box contained a Troxler depth moisture probe, model number 1255, with a 100 millicurie Americium-241:Be source and an origin date of 05/03/1975. The second box contained a Troxler depth density gauge, model number 1351, with a 7.7 millicurie Cesium-137 source and an origin date of 07/13/1982

"The Agency continues to investigate the event."

The State of Arizona will notify the Governor's Office and the FBI.

* * * UPDATE AT 1553 EDT ON 05/20/14 FROM BRIAN GORETZKI TO S. SANDIN VIA EMAIL * * *

The State of Arizona identified the Arizona licensee who picked up and dropped off the sources at the Agency.

"The Am-241:Be probe/gauge has 3 labels on it with all different model and serial numbers. They are as follows:

Model: 104a Serial #: J-3475

Model: 1255 Serial #: 810

Serial #: Am-239 Date: 5/30/75

"The Cs-137 gauge has the same thing. They are as follows:

Model: 504 Serial #: 212

Model: 1351 Serial #: 212

Model: 40-6475 Date: 7/13/82

"[The Agency] crossed referenced the model/serial numbers in the NMED database and did not get any hits."

Notified R4DO (Gepford) and FSME (via email).

60-DAY OPTIONAL TELEPHONIC NOTIFICATION FOR INADVERTENT FAST START OF DIESEL GENERATOR DURING TESTING

"In accordance with 10 CFR 50.73(a)(2)(iv)(A), this 60-day telephone notification addresses an unplanned, invalid actuation of the 2B-B Diesel Generator (DG). The event occurred on 04/16/2014 at approximately 0148 EDT while Watts Bar (WBN) Unit 1 was in Mode 6 for a refueling outage. At this time, an 18 month performance of 0-SI-82-6, '18 Month Loss of Offsite Power DG 2B-B,' was in process which required that 2-HS-82-113 (Maint-Auto Hand Switch Generator 2B-B) be placed in the Auto position. When this action was taken, the 2B-B DG experienced a fast start. At 0314 EDT on 04/16/2014, while in the process of stopping the DG, the DG experienced a second fast start. For both starts of the 2B-B DG, the DG successfully functioned and achieved its rated speed of 900 RPM. Following the second start of the 2B-B DG, an emergency stop was performed on the DG in accordance with SOI 82.04, 'Diesel Generator (DG) 2B-B.' The cause of the invalid starts was determined to be an intermittent open between a relay pin on the R3 relay (DG start relay) and the relay base due to oxidation. This event was documented in TVA's corrective action program as Problem Evaluation Report (PER) 872575.

"The NRC Resident Inspector has been informed of this notification."

AUTOMATIC REACTOR TRIP DUE TO TURBINE TRIP ON LOSS OF CONDENSER VACUUM

"This is an non-emergency event notification to the NRC Operations Center in accordance with 10 CFR 50.72(b)(2)(iv)(B) for a valid actuation of the reactor protection system (RPS) (four hour notification).

"On 05/25/2014 at 0536 EDT, as part of a planned maintenance outage to repair a leaking check valve inside the containment building, Unit 4 power level had been lowered to 19% reactor power for the planned opening of the reactor trip breakers. Unit 4 experienced a loss of condenser vacuum. An automatic turbine trip signal was generated which initiated a reactor trip signal. The reactor tripped as required on the automatic trip signal. Unit 4 is currently in Mode 3 and stable. The loss of vacuum is under investigation at this time. All other plant systems are working as designed."

The reactor trip was uncomplicated with no other safety system actuations. Decay heat is being removed via steam dumps to atmosphere. There is no known primary to secondary leakage. The grid is stable and Unit 4 is in its normal shutdown electrical lineup. Unit 3 was not affected and continues to operate at 100% power.

The licensee has notified the NRC Resident Inspector.

UNUSUAL EVENT DUE TO LOSS OF OFFSITE POWER

At 0702 EDT on 5/25/14, Millstone Units 2 and 3 experienced a loss of offsite power and subsequent trip of both units. An Unusual Event was declared by Millstone Units 2 and 3 at 0715 EDT.

Power is currently being supplied to all emergency busses by the emergency diesel generators. Offsite power is not available.

At this time, it appears that the loss of offsite power is due to a localized issue in the Millstone switchyard. The surrounding areas were not affected.

A decision was made to take the NRC to monitoring mode at 0749 EDT with Region 1 in the lead.

Notified DHS SWO, FEMA Ops Center, NICC Watch Officer, DOE Ops Center, USDA Ops Center, HHS Ops Center, and Nuclear SSA via email.

* * * UPDATE FROM MICHAEL CICCONE TO DANIEL MILLS AT 1330 EDT * * *

"The loss of offsite power was due to one main line coming into the plant shorting to ground. Emergency plan procedures have been implemented, natural circulation has been established, and the plant is stable. Offsite electrical power has been restored to both Unit 2 and Unit 3. Emergency diesel generators have been secured, and plant equipment has been restored to a normal line up.

"Extended loss of instrument air following the loss of offsite power complicated the recovery actions. The normal reactor coolant system letdown flow path was not able to be established. This resulted in the rupture of the pressurizer relief tank rupture disk inside containment. The relief valve on the volume control tank lifted when restoring normal letdown. This caused the primary drains transfer tank to overflow into the auxiliary building. This overflow path has been isolated. Supplementary leakage collection system radiation monitor HVR-RE19B, and auxiliary building normal ventilation radiation monitor HVR-RE10B, are indicating normal levels."

During the entire period, backup assessment capability was functional, dependent upon redundant assets as described in existing station documentation and/or functionality of the control room alarm typer. Additionally, the station computer alarms and Safety Parameter Display System remained functional during the entire time period.

"The licensee will continue to investigate the annunciator system.

"The licensee notified the NRC Resident Inspector."

The licensee will also notify State and local government agencies.
