"At 0107 CDT on October 23rd, 2014, both doors in one of the Secondary Containment airlocks were momentarily open concurrently. This occurred during vessel drain down following refueling activities, an Operation with the Potential to Drain the Reactor Vessel (OPDRV), which required Secondary Containment to be operable. The doors being open at the same time resulted in the momentary inoperability of Secondary Containment. One of the doors was immediately closed, and Secondary Containment was restored to an operable status.
"The station [Duane Arnold] has now completed the OPDRV associated with vessel drain down, and Secondary Containment is no longer required to be operable.
"The Resident Inspector has been notified."
* * * RETRACTION FROM BOB MURRELL TO JOHN SHOEMAKER AT 1232 EST ON 12/17/14 * * *
"The purpose of this notification is to retract a previous report made on 10/23/2014, at 0948 [EDT] (EN 50560). Notification of the event to the NRC was initially made as a result of an event where both doors in one of the Secondary Containment airlocks were momentarily open concurrently. This occurred during vessel drain down following refueling activities, an Operation with the Potential to Drain the Reactor Vessel (OPDRV), which required Secondary Containment to be operable. The doors being open at the same time resulted in the momentary inoperability of Secondary Containment. One of the doors was immediately closed, and Secondary Containment was restored to an operable status.
"Subsequent to the initial report, NextEra Energy Duane Arnold (NextEra) has determined that the doors in question were not mechanically degraded such that they were incapable of being closed. A momentary condition of having both secondary containment airlock doors open for a matter of seconds is not an event or condition that could have prevented the fulfillment of a safety. Furthermore, the conduct of OPDRVs during a momentary opening of both secondary containment doors that is immediately rectified does not constitute a condition prohibited by TS.
Therefore, this event is not considered a Safety System Functional Failure or a Condition Prohibited by TS and is not reportable to the NRC as a Licensee Event Report (LER) per 10 CFR 50.73.
The NRC Senior Resident Inspector has been notified.

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text LOST DEVICE WITH CADMIUM-109 SOURCE
The licensee reports the loss of General License Niton XRF (X-Ray Fluorescence) Device, serial # 8622, containing a (Cadmium) Cd-109 source, Serial # NR-7169. The original device source strength was 40 milliCurie however, the current source strength is assayed at .26 milliCurie. The licensee believes the device was accidently disposed of as waste for recycling from the Detroit, MI facility. Efforts to locate and recover the device have been unsuccessful. More information will be provided as it becomes available.
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.

| Event Text AGREEMENT STATE REPORT - LEAKING NI-63 SEALED SOURCES
The following information was provided by the Commonwealth of Massachusetts via email:
"Morpho Detection is in the process of moving its facility, and as part of this process wipe-tests were conducted on older Ni-63 sealed sources (approx. 8 - 10 millicuries per source), that were in storage prior to transfer to a contractor for disposal. The leak tests showed that four groups of sealed sources had results that were above the threshold limit of 5 nanocuries. Thus one or more of the sealed sources within each group showed signs of leakage or contamination. Licensee reports that additional wipe tests were not conducted to determine the specific sources that were leaking.
"The Ni-63 sealed sources were identified by the licensee as Model Number NER-004 and GE Homeland Protection detector heads containing those sources.
"Overall, the leak tests revealed that Ni-63 contamination ranged from 0.030 to 0.98 microcuries for the four groups of sealed sources that were analyzed.
"Wipes were taken by the licensee by swabbing the exterior of a group of sealed sources of similar type (R&D dual-source detector heads were differentiated from R&D single source detector heads, etc.), thus the multiple sources within a group were swabbed with a single swab which was ultimately analyzed by a licensed contractor (Radiation Safety Control Services, Stratham NH).
"Subsequent to finding contamination, the sources were placed in containers, sealed, and wipe-tests (using swabs) were carried out on the exterior of the storage containers along with the interior and exterior of the cabinet in which they were being stored The wipe tests of the containers and cabinet showed no levels that indicated Ni-63 contamination.
"The licensee disposed of the sealed sources by contracting the services of Viola Environmental Services (12/09/14).
"The Agency [Commonwealth of Massachusetts] considers this event open.
"Equipment problems:
R&D Dual-source detector heads (9 dual sources), 1 swab, resulted in a finding of 0.98 microcuries
EntryScan detector heads (6 sources), 1 swab, resulted in a finding of 0.069 microcuries
R&D Single-source detector heads (9 single sources), 1 swab, resulted in a finding of 0.155 microcuries
Ni-63 bare sources (9 sources), 1 swab, resulted in a finding of 0.0301 microcuries" |

| Event Text INTERIM REPORT - POTENTIAL PART 21 NOTIFICATION
The following report was received via fax:
ASCO reviewed a Part 21 notification, received from Steris Isomedix Services, to see if the reported non conformance would impact qualification levels. Based on this review, ASCO determined that even if the radiation levels, applied to components, were lower than reported on the original certifications, the additional radiation dose added to meet the 10% margin suggested by IEEE 323 would envelope this variation. Therefore, the qualification levels listed in ASCO qualification reports would not be impacted. Based on this review, ASCO determined that it was not necessary to implement 10 CFR part 21 notifications since the reported qualification levels remain unchanged.
If you have any questions, you can contact Michael Adase at Michael.adase@emerson.com or 803-641-9345.
Note: The NRC has received reports from four (4) other Steris Isomedix customers concerning this issue; EN #50253, #50285, #50359, and #50434. |

"On 12/13/14 at 1700 [EST] hours, during a planned Unit 1 maintenance outage the licensee identified leakage from a weld on the [.75 inch] lower seal vent piping connected to the 1B reactor recirculation pump lower seal area. The location is within the reactor recirculation loop isolation valves, therefore isolable from the reactor vessel. The piping is ASME Class 2 and is a reactor coolant pressure boundary. The reactor was in mode 3 at the time of discovery. Control Room notified at 1345 [EST] on 12/16/14, that requirements for 10CFR50.72(b)(3)(ii)(A) were not met.
"This event is being reported as a degraded condition pursuant to 10CFR50.72(b)(3)(ii)(A)."
The unit was taken to Mode 4 and the seal vent piping repair was completed.
The NRC Resident Inspector has been notified. |
