"On March 13, 2015 at 0100 [CDT], it was identified that fuel assembly QAD224 was mis-oriented 180 degrees at core location 51-40. The intended orientation was [southeast]. However the assembly was identified as being [northwest]. This issue was identified during the core verification process. In the current core configuration, there is not a bounding analysis that assures adequate Shutdown Margin.
"This event is reportable under 50.72(b)(3)(ii) as an unanalyzed condition that significantly degraded plant safety.
"The NRC Resident Inspector has been notified."

"The purpose of this notification is to retract the ENS notification made on March 13, 2015 (ENS 50882). An evaluation has determined that Shutdown Margin was met with the mis-oriented fuel bundle. Therefore, the threshold for reporting the issue as a degraded or unanalyzed condition was not met (NUREG 1022 Revision 3 - Event Report Guidelines Section 3.2.7).
"The NRC Resident Inspector has been notified."

The following information was provided by the State of Arkansas via email:
"On March 30, 2015, at 0703 [CDT], McGeorge Contracting Company, Inc., Arkansas Radioactive Material License Number ARK-0785-03121, reported a stolen moisture density gauge. The gauge has been stolen from a temporary jobsite on Interstate 40, near North Little Rock, sometime between 1600 [CDT] on Friday, March 27, 2015 and 0625 [CDT] on Monday, March 30, 2015.
"The gauge is identified as a Troxler Electronic Laboratories, Model 3440, Serial Number 25959, with original source activities of 40 millicuries of Am-241:Be and 8 millicuries of Cesium-137.
"The gauge was stolen along with other engineering equipment utilized by the licensee.
"The Arkansas State Police has investigated and the Arkansas Department of Health has issued a press release.
"The Radioactive Materials Program is monitoring this event under Arkansas Event Number AR-2015-002."
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.

The following was received from the State of Texas via email:
"On March 4, 2015, the licensee [University of Texas MD Anderson Cancer Center] reported that a malfunction had occurred involving its JL Shepherd Mark I, Model 30, self-contained irradiator. Device source: 10,000 curies [Cs-137], June 25, 1986, Cs-137, JL Shepherd Type 6810, SN 85CS26; Device mounting: JL Shepard Mark I Model 30 Irradiator, SN 1039. The source would not fully raise nor would it lower into the fully shielded position. The interlock system functioned as designed and the irradiator door remained locked in the source shielded position. The manufacturer was contacted and a service representative will be servicing the irradiator. This is the second incident with this device within the past month (see EN 50862). Investigation ongoing, file open."

The following was received from the State of Texas via email:
"On March 31, 2015 the Agency [Texas Department of State Health Services] was notified by the radioactive materials reciprocity coordinator that it received a notice of an engineering company scheduled to complete work on a nuclear source stuck shutter. The licensee [Westlake Longview Corporation] was called without contact. A message was left on voicemail. The engineering company was contacted and stated that it was hired to complete work on a sealed source gauge for level measurements due to a stuck shutter. The item is a Ronan Model 4F6S, Cs-137, 40 mCi, Serial Number M7352. The investigation into this case is ongoing. Further updates will be provided in accordance with SA 300 guidelines."

"A loss of Main Generator Load which caused a Reactor Trip on Unit's 1 & 2. A switchyard voltage transient from a highline occurred which caused an undervoltage condition on both units' safety related 4KV buses.
"Unit 1 is on normal heat removal to the condenser.
"Unit 2 is on auxiliary feedwater and normal condenser bypass valves for temperature control. An Auxiliary Feedwater Actuation System (AFAS) actuation occurred on Unit 2.
"The [Unit 2] 2B emergency diesel generator did not start and load on it's respective 24-4 KV bus. The 24-4KV Bus was re-powered from the alternate feeder breaker. Cause of the emergency diesel failure to start is under investigation.
"All safety functions are met for both units."
All control rods fully inserted. The site is in a normal shutdown electrical configuration powered from offsite. The site plans to stay in Mode 3, pending restart.
The licensee notified the NRC Resident Inspector, State and local authorities. A press release is planned. |

"This is a non-emergency report.
"On April 7, 2015, while the Harris Nuclear Plant was shut down for a scheduled refueling outage, the reactor vessel head penetrations were being examined in accordance with Inservice Inspection Program. Ultrasonic examinations identified a flaw in a head penetration nozzle. The unit is in a safe and stable condition. The flaw will be repaired prior to startup from the refueling outage.
"The flaw and repair have no impact to the health or safety of the public.
"The NRC Resident Inspector has been informed."
An extent of condition investigation is on-going. |

"Luminant Generation Company LLC (Luminant Power) has completed a review of seismic monitor performance at the Comanche Peak Nuclear Power Plant (CPNPP) over the last three years. The CPNPP emergency preparedness plan requires seismic monitoring instruments to diagnose an earthquake for emergency action levels (EAL) HA1.1 (seismic event greater than OBE (operating basis earthquake) and HU1.1 (identified seismic event that is less than the OBE). The seismic monitor performance review identified one unplanned instance of monitor unavailability and three instances when planned monitor outage durations exceeded 24 hours. Any loss of seismic monitoring capability results in a major loss of assessment capability for the Alert (HA1.1) and a degraded assessment capability for the Unusual Event (HU1.1) emergency classification. The seismic monitor is currently functional, however it was determined to be non-functional on the following dates:
Unplanned out-of-service:
12/4/2013 through 12/1 0/2013
Planned out-of-service lasting greater than 24 hours:
5/16/2012 through 5/24/2012
3/20/2013 through 3/27/2013
9/29/2014 through 10/1/2014
"The loss of assessment capability is reportable to the NRC within 8 hours of discovery in accordance with 10 CFR50.72(b)(3)(xiii). This report is required per 10 CFR50.72(a)(1)(ii) as an event that occurred within 3 years of the date of discovery. The seismic monitor issues and the missed reporting of the loss of assessment capability have been documented in the CPNPP corrective action program."
This review was prompted by the licensee's evaluation of industry's operating experience. A similar report was received from Limerick Generating Station - EN # 50951.
The licensee informed the NRC Resident Inspector. |

"At approximately 1833 CDT on April 07, 2015, the licensee was notified by the siren vendor (NELCOM) that Dakota County Dispatch reported an inadvertent activation of an emergency siren (D-1), in Dakota County, MN. The cause of the siren activation is unknown. The siren was deactivated at 1810 CDT after sounding for approximately 25 minutes. The siren vendor (NELCOM) has been contacted to repair the siren. The siren remains out of service. This is the only siren out of service within the 10 mile Emergency Planning Zone (EPZ).
"There are 123 Emergency Notification sirens. Of the seven (7) credited sirens in Dakota County, six (6) remain in service. Thus, emergency notification capabilities remain in effect.
