AGREEMENT STATE REPORT - NUCLEAR GAUGE SHUTTER STUCK OPEN
The following information was received from the Texas Department of State Health Services (the Agency) via email:
"On August 25, 2020, the Agency was notified by the licensee's consultant that during routine inspections the shutter on a Vega model SHGL-1 nuclear gauge containing a 2,000 milliCurie (original activity) cesium-137 source was stuck in the open position. Open is the normal position for the shutter. The gauge does not create an exposure hazard to any individual. The licensee's service provider is aware of the failure. Additional information will be provided as it is received in accordance with SA-300."
Texas Incident Number: 9786

AGREEMENT STATE REPORT - TWO LOST SOURCES
The following is a summary of information received via email:
On August 24, 2020, the licensee notified the New Jersey Department of Environmental Protection of two lost sealed sources. The sources had been sent from the licensee's Austin, Texas facility to their Fair Lawn, New Jersey facility, and are reported as missing by the shipper. The two sources were Ni-63 foil sources with an activity of 10 mCi each (S/N: AO-2484 and AO-5478). Each source was in a Life Technology Holdings, model Trace 1300, electron capture detector (S/N: 719420216 and 719420261).
The shipper has been searching for the sources, but at this time considers them missing with little likelihood of recovery. The shipper's tracking system indicates that the sources were delivered to the licensee's Fair Lawn facility, but that location has stated they never received the sources. The address to which the sources were reportedly delivered does not exist and the person who reportedly signed for the package is unknown to the licensee.
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.

REACTOR SCRAM AFTER LOSS OF FEEDWATER - GRAND GULF
"On August 24, 2020 at 2305 CT at Grand Gulf Nuclear Station (GGNS) an Automatic Reactor Scram occurred after a trip of the Reactor Feed Pump B and subsequent lowering of reactor water level to 11.4 inches Narrow Range. The scram occurred with Reactor Power at 14% and the main generator offline.
"All control rods fully inserted and there were no complications. All systems responded as designed.
"Main Steam Isolation Valves were manually closed to control reactor cooldown, Currently GGNS reactor pressure is being maintained at 450-600psig. Reactor water level is being maintained with condensate through startup level control.
"No radiological releases have occurred due to this event from the unit.
"The NRC Resident has been notified."
Decay heat is being removed via the main condenser.
Notified R4DO.

AGREEMENT STATE REPORT - STUCK SHUTTER
The following was received from the Pennsylvania Bureau of Radiation Protection via email:
"On August 24, 2020, the licensee identified a failure of the shutter assembly and indicator on one of its Valmet Multi-Filler Module, Serial Number 0022 containing 20 mCi of lron-55. The shutter had failed closed. The gauge was immediately removed from service. The manufacturer was contacted, and the broken shutter mechanism was removed and replaced on August 26, 2020. The shutter mechanism was then tested and confirmed as operating properly. No exposures were resulted from this event."
Event Report ID No.: PA200018
