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. This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint.

The exposure device is a QSA Global Sigma 880 with a 97 Curie Iridium-192 source. The source disconnect occurred at 7:00 AM 9/30/08 at a construction site three miles northeast of Moses Lake, Washington. The President and Radiation Safety Officer (RSO) of the licensed IR company are on scene with 12 company employees to correct the situation. The radiographer had previously made several exposures on pipe welds earlier in the day before the disconnect occurred. The source remained at the end of the guide tube, in the collimator, when the radiographer tried to retract it into the device. The radiographer tried this several times. A large area at the construction site has been secured by barricades and the IR personnel are guarding the radiation area. At present, it appears that personnel have not received any elevated or unusual exposure as a result of the disconnect. The IR company is working with the Office of Radiation Protection and the radiography device manufacturer to develop a plan to retrieve the source. DOH staff were sent to the location to assure radiation safety procedures are followed and independent measurements are made."

The noncompliance involves a batch of Carbozine 11 SG Base that is not curing properly. It forms a poor quality film. "A customer notified Carboline of concerns regarding the cure of a particular batch of Carbozine 11 SG. Technical Service originally felt it was application related and worked with the customer. An internal report was opened once cure issues remained after working with their technical department. An analysis of the batch by our plant Quality Control was requested; the results did not confirm the problem. Material was then sent into Saint Louis R&D for additional analysis. On Tuesday, October 8, 2008 the analytical evaluation was reviewed by the product chemist and the batch cure issues were confirmed. "The batch was placed on hold and reports have been run to determine where the batch has been shipped. Carboline is requesting that the affected companies review their stock of Carbozine 11 SG and return any material with the batch number of 8G9892L. Further work is being done to determine the cause of cure issues with this batch of Carbozine 11 SG. At this time, Carboline has confirmed that this material is not curing properly and forms a poor quality film." | Fuel Cycle Facility | Event Number: 44558 | Facility: PADUCAH GASEOUS DIFFUSION PLANT RX Type: URANIUM ENRICHMENT FACILITY Comments: 2 DEMOCRACY CENTER 6903 ROCKLEDGE DRIVE BETHESDA, MD 20817 (301)564-3200 Region: 2 City: PADUCAH State: KY County: McCRACKEN License #: GDP-1 Agreement: Y Docket: 0707001 NRC Notified By: BILLY WALLACE HQ OPS Officer: STEVE SANDIN | Notification Date: 10/10/2008 Notification Time: 14:20 [ET] Event Date: 10/09/2008 Event Time: 15:37 [CDT] Last Update Date: 10/10/2008 | Emergency Class: NON EMERGENCY 10 CFR Section: RESPONSE-BULLETIN | Person (Organization): SCOTT SHAEFFER (R2) TIM MCCARTIN (NMSS) | Event Text 24-HOURS BULLETIN 91-01 REPORT INVOLVING FAILURE TO VISUALLY INSPECT STORAGE CYLINDERS The following information is provided without quotation for readability: DESCRIPTION: On 10/09/08 at 1537 hours it was determined that procedure CP4-CU-CH6430, "In Storage Fissile Cylinder Inspection", does not fully meet the periodic inspection requirements of NCSA GEN-003. GEN-003 requires inspection every four years of all thick wall cylinders that contained fissile material since they were last washed on the inside of the cylinder. Only cylinders that were filled with fissile material on their last fill have been identified for inspection. Cylinders filled with fissile material, emptied and subsequently filled with non-fissile material and emptied, have not been inspected as required. Approximately 73 Cylinders that have contained fissile material since their last washing have not been inspected in violation of the requirement of NCSA GEN-003, these cylinders could contain residual nonvolatile material referred to as heel. Potentially the residual heel could contain fissile material. Double contingency is maintained by implementing two independent controls on one parameter (moderation). The first leg of double contingency relies on the design of the cylinder to ensure moderation control. Cylinders are designed to the requirements of ANSI N14.1 and ensure that it is unlikely for the cylinder wall to breach and allow water intrusion. This control on moderation was not violated. The second leg of double contingency relied on inspections every 4 years of the cylinder wall, valve, and plug for abnormal corrosion. This control ensures that in the event of a cylinder breach, it is unlikely that sufficient moderation to cause a criticality will enter the cylinder before it is identified and mitigated. Since the cylinders were not inspected within the 4 year time frame as required, this control on moderation was violated. The NRC Resident Inspector has been notified of this event. PGDP Problem Report No. ATRC-08-2918; PGDP Event Report No. PAD-2008-31; NRC Worksheet No. 44558. SAFETY SIGNIFICANCE OF EVENTS: Although a control requiring inspection of the cylinders every 4 years was violated, no cylinder breaches occurred. Later inspections identified no cylinder integrity issues, moderation control was lost and double contingency was not maintained. POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO(S) OF HOW CRITICALITY COULD OCCUR): In order for a criticality to be possible, more than 10kgs of water would have to enter a breach in a cylinder which contains more than a critical mass of material enriched to greater than 1.0 wt% 235U. CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION, ETC.): Moderation. ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS LIMIT AND % WORST CASE CRITICAL MASS) : There were 73 cylinders which were not inspected as required. These cylinders had at one time held fissile material. The cylinders were emptied except for a small residual heel and then filled with non-fissile material. The non-fissile material was then emptied leaving only the residual heel in the cylinder. Cylinder heels are typically less than 50 pounds. Assay is always less than 5.5% enrichment. NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION OF THE FAILURES OR DEFICIENCIES: NCSA GEN-003 requires cylinders containing material enriched to greater than or equal to 1.0 wt % 235U to be inspected every 4 years to identify significant signs of degraded cylinder wall, valve and plug. These cylinders were filled with fissile material, emptied and then subsequently filled with non-fissile material and then emptied again, but were not inspected within the four year requirement. CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEMS AND WHEN EACH WAS IMPLEMENTED : Cylinders have been inspected per the CP4-CU-CH6430 and the identified cylinders were found to comply with NCSA GEN-003. * * * UPDATE AT 1750 EDT ON 10/10/08 FROM BILLY WALLACE TO STEVE SANDIN VIA FAX * * * On 10/10/08 at 1500 CDT, an additional 8 cylinders were discovered which had not been properly inspected. The additional cylinders were of a different size than the initial cylinders found, but fall under the same requirement. The additional cylinders have been inspected and all met the NCSA requirements.

Letdown was isolated within 13 minutes, isolating the leakage. Upon review of the level trends of the Pressurizer Relief Tank level changes, approximately 574 gallons were diverted from the Reactor Coolant system. This would result in an RCS leakage rate of 44 gpm of RCS Identified Leakage. At the time that the calculation of leakage rate was discovered, it was immediately recognized that this met the requirements for EAL 4R, 'RCS Identified Leakage greater than 25 gpm'.

"At approximately 0500 hours, plant operators were closing the main steam isolation valves (MSIVs) for plant shutdown. Once the MSIVs were closed, the reactor coolant system (RCS) cooldown rate decreased significantly. The 'A' atmosphere steam dump valve (ASD) was then opened. Shortly after the ASD was opened, the MSIV was also opened. With both the MSIV and ASD open, however, the 'A' S/G water level swelled until the P-14 S/G Hi Level protective interlock setpoint was reached, resulting in a feedwater isolation (FWIS) actuation at 0505 hours. "Subsequent to the FWIS actuation, plant operators took action to recover from the FWIS in accordance with off-normal operating procedure OTO-SA-00001, 'Engineered Safety Feature Actuation Verification and Restoration.' The motor-driven auxiliary feedwater pumps were started to restore S/G water level. However, S/G water level lowered rapidly in response to the cold auxiliary feedwater flow to the S/G. A S/G Low-Low water level trip signal was then reached on the 'A' S/G, thus resulting in a reactor trip system actuation at 0508 hours.
