EN Revision Text: CONCURRENT NOTIFICATION At approximately 1525 (EDT) on October 1st, 2018, Fire Riser 318 which serves both non-contaminated and contaminated areas in (Fuel Manufacturing Operations) (FMO), was taken out of service due to a pin hole leak in the pipe. Water was contained and surveys were completed to ensure no contamination was released into non-contaminated areas. The New Hanover County Deputy Fire Marshall was notified at 1655 (EDT) on October 1st, 2018, per State code requirements. An hourly fire watch was implemented for surveillance of the affected areas. Because the New Hanover County Deputy Fire Marshall was notified, a concurrent notification to the NRC Operations Center is being made per 10 CFR 70, Appendix A(c). The licensee will notify NRC Region 2 and the State of North Carolina Radiation Protection Section.

• * * UPDATE ON 10/4/18 AT 1335 EDT FROM PHILLIP TO OLLIS * * *

The leaking sprinkler pipe fitting was replaced this morning and the system was restored to service at approximately 11 AM, 10/4/18. The NHC (New Hanover County) Deputy Fire Marshal was notified via telephone of the return to service at 11:50 AM, 10/4/18. Notified the R2DO (Lopez), NMSS Events Notification via email.

At approximately 1330 EDT, 3/28/2018, a report was sent to the State of North Carolina Department of Radiation Protection. The report is below: 'Pursuant to 10A NCAC 15.0309, Global Nuclear Fuel Americas, LLC (GNF-A) is providing this report for discovery of a damaged self illuminated exit sign in the Fuel Manufacturing Operations (FMO) building. On February 26, 2018, it was discovered that one tube out of the twelve originally installed tubes in a generally licensed exit sign was damaged. The sign was in storage and not being used at the time and there was no significant exposure as a result of the event. The sign is believed to be a model number 101 or 201, originally containing a maximum of 25 Ci of tritium manufactured and distributed by:

Evenlite, Inc., 220 VFW Avenue.,Grasonville, MD 21638.

Arrangements were made to properly dispose of the sign. It was shipped offsite for recovery or disposal on March 23, 2018 to SRB Technologies (NC Radioactive Material License 034-0534-2).' This report to NRC is being made in accordance with 10 CFR 70 Appendix A (c) - Concurrent Reports (... notifications to other government agencies has been or will be made, shall be reported to the NRC Operations Center concurrent to the news release or other notification.) The Licensee has notified NRC Region 2. 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.

Feed tube level sensor was found to be in a state such that it has failed as an IROFS (Item Relied On For Safety) for a fire accident sequence leading to the loss of a criticality control. Another IROFS is in place and the accident sequence continues to meet performance requirements. Less than a safe mass was always maintained. This event is being reported because only one item relied on for safety, as documented in the Integrated Safety Analysis summary, remains available and reliable to prevent a nuclear criticality accident, and has been in this state for greater than eight hours. Portion of the plant affected: FMO (Fuel Manufacturing Operation) Press. The licensee notified the North Carolina State Radiation Protection Branch, New Hanover County Emergency Management, and NRC Region II.

• * * UPDATE ON 4/3/14 AT 1457 EDT FROM SCOTT MURRAY TO DONG PARK * * *

On 3/6/14, GNF-A (Global Nuclear Fuels - America) conservatively made a 1 hour event notification (EN 49878) due to a discovery that a feed tube level sensor had failed. After further review, it has been determined that a second control remained available, reliable, and the remaining IROFS was sufficient to meet performance requirements. As a result, the event notification is retracted. Notified R2DO (Vias) and NMSS EO (Lombard).

At about 1045 EDT on 9/13/13, it was discovered that the feed tube level sensor on a press operation is not fail safe upon loss of signal. The sensor is a sole IROFS (Item Relied On For Safety) for a particular sequence. Criticality controls remained in place. Affected equipment has been shut down. No unsafe condition exists. Feed tube level sensor is in place for the sequence to limit mass. At no time was the mass limit exceeded. We are reporting under Part 70, Appendix A, (a)(4) which states that credited IROFS must remain available and reliable. We cannot evaluate reliability in the time required for a 1 hour report. In addition, the affected equipment has been secured. An investigation is underway to determine corrective actions and extent of condition. The license will notify NRC Region 2.

On 9/13/13, GNF-A conservatively made a 1 hour event notification (EN 49341) due to a discovery that a feed tube level sensor is not fail safe upon loss of signal. After further review, it has been determined that the control remained available, reliable and continued to meet performance requirements. As a result, the event notification is retracted. The licensee has notified NRC Region 2. Notified R2DO (Sykes), NMSS EO (Rubenstone), and IRD (Grant).

During a (Global Nuclear Fuels) GNF-A review of the Fuel Manufacturing Operation (FMO) Integrated Safety Analysis (ISA), it was determined at 1:30 PM yesterday (12/3/12) that Items Relied on for Safety (IROFS) associated with the Dry Scrap Recycle furnace operation were improperly analyzed in the ISA. Although criticality controls associated with preventing moderation intrusion exist and these controls remained in place, they were not sufficiently independent to meet performance requirements. At no time was an unsafe condition present. The affected equipment has been shut down. An investigation is continuing which will provide additional corrective actions and extent of condition. While this did not result in an unsafe condition, this event is being reported pursuant with the reporting requirements of 10CFR70 Appendix A (b)(1) within 24 hours of discovery. The licensee will notify state and local governmental agencies and has notified the onsite NRC Inspectors.

* * * UPDATE FROM SCOTT MURRAY TO PETE SNYDER AT 1600 EST ON 12/5/12 * * * 

An extent of condition review determined there are three more areas with IROFS that are not sufficiently independent. These areas are vaporization/conversion of the Dry Conversion Process, an area used to pack material for recovery and a hood that is used to transition to a moderation restricted area in the gadolinia shop. The affected equipment in these areas has also been shut down and the investigation continues to identify additional corrective actions. The licensee notified the onsite NRC Inspectors. Notified R2DO (Blamey) and NMSS (Rahimi).

At 12:39 PM (EDT) it was discovered that only one Items Relied On For Safety (IROFS) remained in place to prevent a Criticality Event in the ceramics area of the Fuel Manufacturing Operations facility. The failed IROFS was Fuel Business System (FBS) Control of Mass of Uranium Transportable Container (IROFS 900-01), due to an overweight pellet boat. The IROFS that remained in place at all times was Spill Identification and Cleanup (IROFS 900-11). The initiating event for the accident sequences (spill of a pellet boat) did not occur. The licensee notified the NRC Resident Inspector.

• * * UPDATE AT 1456 EDT ON 8/17/2012 FROM SCOTT MURRAY TO MARK ABRAMOVITZ * * *

The pellets have been removed from the overweight boat and placed into an approved container; the IROFS for these accident sequences have been restored. The extent of condition is being evaluated and at this time no other overweight boats have been identified. Region II and NMSS HQ and other notifications have been completed. Notified the R2DO (Guthrie) and NMSS (Waters).
