Event Notification Report for March 22, 2018

TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO PRESSURE BOUNDARY LEAKAGE

"This notification is being provided in accordance with 10CFR50.72(b)(2)(i), Plant Shutdown required by Technical Specifications, and 10 CFR 50.72(b)(3)(ii)A, Degraded or Unanalyzed Condition.

"At 0300 CDT on 3/22/18, on LaSalle Unit 1, a through-wall (welded joint) leak was identified on a 3/4 inch vent line off of the bonnet of the 1B33-F067B, 1B Reactor Recirculation Pump Discharge Valve. This condition qualifies as pressure boundary leakage, which requires entry into Technical Specification 3.4.5, Reactor Coolant System Operational Leakage, Required Action C, to be in Mode 3, Hot Shutdown, by 1500 on 3/22/18 and Mode 4, Cold Shutdown, by 1500 on 3/23/18. This leakage is significantly less than 10 gallons per minute and therefore, does not meet the threshold for entry into the Emergency Action Plan. At the time of discovery, Unit 1 was in Mode 1 - Run."

Shutdown began at 0500 CDT and the estimated completion to cold shutdown is 2000 CDT. All necessary shutdown equipment is available.

There is no impact to Unit 2.

NRC Resident Inspector was notified.

See EN 53282 for corresponding report from the State of North Carolina.

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.

AGREEMENT STATE REPORT - DISCONNECTED RADIOGRAPHY SOURCE

The following is a synopsis of information received via E-mail:

On March 22, 2018, LA-DEQ (Louisiana Department of Environmental Quality) received an on-line notification that CAN USA Inc. had an incident where a radiography source was irretrievable during operations at a temporary jobsite at the Phillips 66-Alliance Refinery in Belle Chase, LA.

The crew stated they had made an exposure and were performing their post-job survey when the survey meter indicated the source was not in the shielded position. The radiography crew realized the source could not be retracted back into the shielded position and called the assistant RSO (Radiation Safety Officer) for radiation safety assistance.

The assistant RSO arrived at the jobsite at 0615 CDT. The assistant RSO covered the source in the guide tube with lead shot bags to reduce the exposure during the retrieval operation. It was determined that the guide tube had disconnected from the exposure device. The guide tube was reconnected, the source was returned to the shielded position, and an investigation into this incident begun. The assistant RSO completed the retrieval work at approximately 0645 CDT. The assistant RSO's direct read pocket dosimeter had an exposure of approximately 60 mR.

The exposure device and associated equipment (crankout control and source guide tube) were taken to the CAN USA facility for further evaluation. The equipment is a QSA Global Model 880 Delta exposure device, S/N D9222, utilizing a 70.7 Ci Ir-192 source, S/N 63452-G. An internal investigation continues into this irretrievable source incident.

The following update was submitted by the Louisiana Department of Environmental Quality via email:

"Updated information:

"A source retrieval has developed into a situation involving, licensed activities, equipment QC/QA practices and personnel qualifications.

"QSA Global Delta 880, S/N D9222; source [approximately] 70 Ci of Ir-192 s/n 63452-G
Associated Equipment: 3rd party, drive cable and source guide tube. (not Amersham/QSA Global manufactured equipment)
The connector did not appear to be compatible with the exposure device source assembly in the Delta 880 device. (excessive use)
A misconnect/disconnect test was not performed on the source assembly and 3rd party associated equipment (drive cable and guide tube).
Assessment and Evaluation: the exposure device and associated equipment were transferred to QSA Global, Baton Rouge, LA then to QSA Global Burlington, MA.

"CAN USA Inc. was not licensed to perform source retrievals nor did they contact a 'qualified licensed radiation service' company to perform the source retrieval. The Corporate RSO, [deleted] was available by telephone. There was no site/assistant RSO trained or qualified to perform the source retrieval.

Landaure whole body badges immediately processes for three individuals, with the Maximum exposure 290 mrem. The acting site RSO, [deleted] whole body badge is 'lost' in the system.
The individuals involved in the source retrieval are having cytogenetic/chromosomal blood sample analysis by REACTS Medical Dosimetry Dept./ORISE.ORAU; results pending.

"Analytical Stress Employees.
Three non-radiation workers were evacuated from the vicinity of the disconnected source and evaluated by blood sample analysis.

"SWAT Specialty Welding and Turnaround:

AGREEMENT STATE REPORT - MISSING TUBE FROM TRITIUM EXIT SIGN

The following information was received via E-mail:

"Licensee reports that on 3/22/2018 it was determined that a tube from an Everglo Tritium Exit sign was missing. The other three tubes were in the sign. The discovery was made as the sign was being prepared for shipment to disposal. At this time, there is no suspected excessive exposure to employees or members of the public.

"Licensee will follow up with additional information [as required] per 10 CFR 20.2201(b). When this report is received by the NC Radioactive Materials Branch, this event will be updated to complete the record."

AGREEMENT STATE REPORT - RADIOGRAPHY PERSONNEL OVEREXPOSURE

The following information was received via E-mail:

"On 03/23/18, the Radiation Safety Officer (RSO) (appointed RSO since the merge with TEAM) contacted RHB (California Department of Public Health, Radiologic Health Branch) to report an occupational overexposure to one of their radiographer trainers. On 03/22/18, the licensee was made aware of an overexposure to a trainer when the trainer's instadose dosimeter was processed. The badge reading indicated a whole body exposure of 5769 mR (licensee processes instadose dosimetry every two weeks for all the users). Further investigation revealed that the radiographer assistant that worked with this trainer also received a whole body exposure of 4583 mR. Preliminary investigation indicates the individuals may have received the recorded exposure during radiographic operations conducted at Chevron Refinery, Richmond, CA, where the source apparently may not have been fully retracted into the shielded position following an exposure. It is believed that a confirmatory survey was not performed following the exposure.

"The exposure device involved is an INC-IR100 camera, device S/N 6756, with an activity of 88.9 Ci of Ir-192.

"Both individuals have been removed from any radiographic operations. The exposure device was inspected and did not show any signs of defects or damages. The licensee's investigation is ongoing and RHB will be following up on this incident.

"Note: RHB is in the process of merging the two licenses, Qualspec, LLC and Team Industrial Services RML # 6720."
