POTENTIAL ISSUE REGARDING INCORRECT INDUSTRIAL IRRADIATION DOSE

The following information was received via facsimile:

Nutherm International, Inc. was notified by Steris Isomedix Services that the applied radiation dose reported on their Component Irradiation Certificates did not account for all uncertainties involved (i.e. density of unrelated products in carriers, off-carrier location within the irradiator and Cobalt-60 source decay). This issue was originally identified as part of NRC Inspection Report No. 99901445/2014-201.

"Nutherm International, Inc. is conducting an evaluation to determine whether a defect as defined by 10 CFR Part 21 exists. The impact of this failure to account for all uncertainties will be evaluated for all projects that required data from any sample irradiated by this supplier.

"At the conclusion of the evaluation, any customer impacted by this issue will be notified and the U.S. Nuclear Regulatory Commission will be notified in accordance with the requirements of 10 CFR Part 21.21.

"If you have any questions regarding this issue please do not hesitate to contact Adrienne Smith, Quality Assurance Manager at 618-244-6000, adrienne.smith@nutherm.com."

The supplier will update this report when the evaluation is complete. This event report was originally received by the NRC Operations Center on 08/01/2014

* * * UPDATE AT 1727 ON 8/31/2015 FROM THOMAS STERBIS TO MARK ABRAMOVITZ * * *

The following information was received via fax:

"Nutherm has identified one customer where there is a potential impact to the conclusions of the equipment qualification that Nutherm does not have the capability to perform further evaluations to determine if a defect exists.

"Nutherm International, Inc. performed equipment qualification testing for SOR, Inc., Lenexa, KS under SOR, Inc. Purchase Order number 166984 which included irradiation performed by Steris Isomedix. Based on the location of the sample during the irradiation and the total variability for this location provided by Steris Isomedix, Nutherm has verified that the test specimens received a minimum irradiation dose that meets the customer's TID requirement but does not meet the customer's TID requirement with the 10 percent IEEE 323 margin.

"In accordance with the requirements of 10 CFR Part 21.21, SOR Inc. has been notified regarding this issue to allow them to evaluate this deviation or failure to comply."

Event Text

LOST/MISSING AIRCRAFT ICE DETECTOR

"On 31 July 2015, Fleet Readiness Center East (FRC East) Radiation Safety Officer (RSO) was notified that an H-53E ice detector probe was missing. The ice detector probe contains a solid 50 microcurie source of Strontium 90 (Sr-90) sealed within a metal casing. The RSO was notified about the missing probe by the H-53 Task Manager. The last known date and location of the ice detector probe was 4 November 2014 in the Aircraft Line Fiberglass Repair Shop. It is believed the probe has departed FRC East and MCAS [Marine Corps Air Station] Cherry Point as scrap/trash.

"To prevent future recurrence, the following actions will occur:
a. The aircraft line will include a mandatory task line to remove the ice detector probe from the duct any time the duct is removed from the aircraft.
B. A training course will be established to distribute throughout the facility for proper identification, handling, and disposal instructions of all radioactive components. Prior to this incident, training was tailored to specific shops which process these parts. A need for broader training has been recognized and will now include those areas which would not normally receive a radioactive component."

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.

BOTH EMERGENCY DIESEL GENERATORS DECLARED INOPERABLE

"This is a non-emergency notification from Waterford 3. On August 26, 2015, at 0111 CDT, Emergency Diesel Generator (EDG) 'A' was declared inoperable following a trip of EDG 'A' on Generator Differential. Technical Specification (TS) 3.8.1.1 actions b. and d. were entered. EDG 'A' was being routinely run in accordance with OP-903-115, 'Train A Integrated Emergency Diesel Generator/Engineering Safety Features Test', Section 7.4, '24 hr EDG A Run with Subsequent Diesel Start' to satisfy Technical Specification Surveillance Requirement 4.8.1.1.2 6. EDG 'B' was subsequently started per TS 3.8.1.1 action b. (1). At 0740 CDT, EDG 'B' was declared inoperable and TS 3.8.1.1 f. was entered due to the exhaust fan not starting when the diesel engine was started.

"Troubleshooting determined that the EDG B exhaust fan did not start due to HVR-501B (EG B ROOM OUTSIDE AIR INTAKE DAMPER) not opening. Action was taken to isolate air and fail HVR-501B to its open safety position. At 1001 CDT, EDG 'B' was declared operable and TS 3.8.1.1.f. was exited following verification of proper operation of the EDG 'B' exhaust fan.

"Waterford 3 is currently in TS 3.8.1.1 actions b. and d. Actions to verify a temporary EDG is available and restore EDG 'A' to operable status are in progress.

"This event is reportable pursuant to 10 CFR 50.72(b)(3)(v) (A) and 10 CFR 50.72 (b)(3)(v) (D), 'event or condition that could have prevented fulfillment of a safety function of structures or systems that are needed to (A) shut down the reactor and maintain it in a safe shutdown condition' and (D) 'mitigate the consequences of an accident due to both emergency diesel generators being inoperable.'"

"The NRC Resident Inspector has been notified."

"The following is a correction to a non-emergency event notification from Waterford 3 originally made on 8/26/2015:

"On August 26, 2015, at 0111 CDT, Emergency Diesel Generator (EDG) 'A' was declared inoperable following a trip of EDG 'A' on Generator Differential.

"Troubleshooting determined that the EDG B room exhaust fan did not start due to HVR-501B (EDG B ROOM OUTSIDE AIR INTAKE DAMPER) not opening. Action was taken to isolate air and fail HVR-501B to its open safety position. At 1001 CDT, EDG 'B' was declared operable and TS 3.8.1.1.f was exited following verification of proper operation of the EDG 'B' room exhaust fan.
