OFFSITE NOTIFICATION RELATED TO JELLYFISH INFLUX
The licensee was required to secure circulating water pump 26 due to a significant influx of jellyfish. Per the licensee's NPDES (National Pollution Discharge Elimination System) permit, the licensee is required to notify the Maryland Department of Environment of any significant aquatic impact on plant operation. The licensee remained at 100% power throughout. The licensee has not yet restarted the 26 circ water pump pending evaluation of a long term strategy related to the recent jellyfish events.
The licensee notified the NRC Resident Inspector.
See similar Event Notifications 42699, 42700. and 42702.

RESEARCH SAMPLE OF C-14 WAS LOST AT SEA.
The RSO (Irene Sakimoto) for the licensee notified us that while conducting an experiment on a boat at sea (22 degrees 43.48 N and 158 degrees 4.77 W) a sealed source of C-14 (1.8 milliCi) was attached to a line and lowered into the ocean to a depth of 4800 meters. The line became ensnared in the propeller and broke. The sample fell to the bottom of the ocean. The licensee will not be making efforts to retrieve this sealed source.
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.
