AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE FAILURE TO RETRACT

The following is an abstract of information received via E-mail:

On July 17, 2019, a Capitol Ultrasonics (CU) three-person crew was making exposures on a compressor at a chemical plant at ExxonMobil Refinery, at a temporary jobsite in Baton Rouge, Louisiana. The three-person radiography crew consisted of two radiography instructors and an assistant radiographer.

After performing three approximately one minute and 25 second exposures and upon completing the fourth exposure and cranking in the source, the radiography instructor noticed, after rocking the crank-out handle back and forth, that the exposure device auto-lock was not engaging. Before reaching the exposure device, the instructor noticed higher than expected survey readings. Several more attempts were made to crank in the source without success. The instructor at once contacted his Radiation Safety Officer (RSO), as well as the ExxonMobil Safety Superintendent. The crew then immediately extended their restricted area boundary to the 2 mR/hr line. Six to seven radiography technicians of the licensee maintained visual surveillance of the boundary and awaited arrival of their RSO. The exposure device was a QSA Global Model 741OP, serial number, B107, containing 15.1 Ci of Co-60, source Model number, A424-18 and source serial number, 60487B.

The lead technician of the crew leading the incident response prior to the arrival of the RSO, received 30 mR on his direct-reading dosimeter (DRD). The RSO received approximately 17 mR on his DRD by the time that the source was finally placed back in the exposure device in the shielded position. An environmental scientist from the Louisiana Department of Environmental Quality made a site visit to the temporary jobsite of the incident and performed preliminary investigation to include observing the successful retrieval of the source on July 17, 2019, by QSA Global. QSA Radiation Technicians received from 40 to 78.3 mR whole body exposure as a result of performing the source retrieval.

AGREEMENT STATE REPORT - STOLEN MOISTURE-DENSITY GAUGE

The following was received via e-mail:

"On 07/17/19, the California Governor's Office of Emergency Services contacted the Radiologic Health Branch (RHB) to report a stolen moisture-density gauge. The gauge involved is a Troxler Model 3450A, S/N 483, containing 9 mCi of Cs-137 and 44 mCi of Am-241. The gauge was stolen out of a gauge technician's truck parked at a Motel 6 parking lot around 2100 PDT in Oakland, CA. The user had immediately called the Oakland Police Department and was advised to call back at a later time. On the morning of 7/18/19, the Oakland Police Department was contacted again and they declined to take a report due to high volume of incidents. The gauge was chained to the bed of the truck and there were guards present at the parking lot. The licensee will be posting a reward for the safe return of the gauge. RHB will be following up on this investigation."

California 5010 Number: 071719

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 - DENSITY GAUGE SHUTTER FAILED IN OPEN POSITION

The following information was received via E-mail:

"The shutter on a SVP generator [chlorine dioxide] ClO2 density meter failed in the open position. This failure was identified and verified on Saturday, 7/13/19. Berthold inspected the gauge while they were on site on 7/19/19 and are scheduled to come in on the next C mill outage to replace the shield. Outage is tentatively scheduled for 10/9/19. The gauge shutter normally operates in the open position so the failure poses no safety risk during normal operations.

"The SVP generator density meter is Rayonier instrument loop no. 507-081. The source is Cesium-137, 500 mCi, model 2623-100, serial no. ED350A in a LB7440 housing."


* * * UPDATE FROM ROGER WILSON TO DONALD NORWOOD AT 1358 EDT ON 7/19/2019 * * *

The following information was received via E-mail:

In the course of planning for Berthold to come on site to repair the SVP generator density meter shutter, it was discovered that our records on the source were in error. The source is model 2623 Cesium-137, 10 mCi, serial no. EA350A NOT 500 mCi, serial no. ED350.

Notified R1DO (Deboer) and NMSS Events Notification E-mail group.

* * * UPDATE FROM LESLINES LEVEQUE TO ANDREW WAUGH AT 1405 EDT ON 7/22/2019 * * *

The following information was received via E-mail:

"The broken shutter at the SVP salt cake density meter was addressed on 7/18/19. Berthold came on site and replaced the shield with a new one, moving the source from the old gauge into the new. The new shield is a model LB 7440-F-CR device, serial no. 37625-13606."

AUTOMATIC REACTOR SCRAM DUE TO MAIN TURBINE TRIP

"At 1929 EDT on 7/27/2019, with the Unit in Mode 1 at 98 percent power, the reactor automatically scrammed due to a Main Turbine Trip. The trip was not complex, with all systems responding normally post-trip. Main Steam Isolation Valves (MSIVs) were manually closed to prevent exceeding Reactor Pressure Vessel Cooldown Rate. Rector Core Isolation Cooling (RCIC) was manually initiated to stabilize Reactor Vessel Water Level and Pressure following MSIV closure. The Main Condenser and Feedwater are available.

"Operations responded and stabilized the plant. Reactor water level is being maintained via RCIC. Decay heat is being removed by discharging steam to the Main Condenser and RCIC.

"The cause of the Main Turbine Trip is currently under investigation."

The site is in a normal electrical lineup.

The licensee notified the NRC Resident Inspector.
