AGREEMENT STATE REPORT - LEAKING FE-55 SEALED SOURCES

The following information was received via E-mail:

"The licensee's Radiation Safety Officer reported on June 7, 2019 that the licensee discovered on June 6, 2019 that 31 of 34 Fe-55 sealed sources tested positive for Fe-55 contamination upon performance of leak testing of the sources in preparation for disposal of the sources. Six (6) of the 34 sealed sources exceeded reporting limits of 0.005 microCuries of removable contamination for each source. The highest removable contamination for a source was reported to be 0.025 microCuries.

"All sources were used sources returned by customers accumulated by the licensee over a period of several years. The licensee is not certain at this time whether only one or more of the sources is actually leaking and contributed to the contamination of the other sources, all in the same storage container.

"The sources have various manufacturer and model numbers. Most of the sources have a current activity of below one (1) millicurie and the highest activity source is currently approximately six (6) milliCuries.

"All of the sources are secured in a lead storage container, inside a safe, in the licensee's source room, pending appropriate packaging and disposal of the sources. Area surveys were performed by the licensee and the licensee reports that there is no contamination outside of the storage container and no personnel exposures resultant of this event.

"The licensee will provide a written report to the Agency [MA Radiation Control Program] in accordance with condition of its license within 5 days. The Agency considers this event to be open."

AGREEMENT STATE REPORT - POSSIBLE NUCLEAR MATERIAL FOUND

The following information was received via E-mail:

"On 6/7/2019, a worker installing equipment contacted the BRC [Bureau of Radiation Control] in regards to what he believed to be radioactive material. He stated that he found a 'hot room' with boxes marked 'radioactive' that were abandoned. Due to the address, [the material] likely belongs to the listed licensee. Inspectors have been notified to contact the worker installing equipment and investigate."

Florida Incident number: FL19-076

* * * UPDATE FROM MATTHEW SENISON (VIA EMAIL) TO HOWIE CROUCH AT 1100 EDT ON 6/12/19 * * *

The following information was obtained from the state of Florida via email:

"Upon arrival at the facility, inspector performed a radiation and contamination survey which did not reveal any levels above background. There were various shielded containers (sharps, calibration source, pharmacy transport, etc.), however there were no sources or residual radioactive material in them. All materials will be disposed of or recycled as required. Inspector removed all the Radioactive Material and Radiation Area signs and confirmed that there were no x-ray machines on site. No further action will be taken, this incident is closed."

AGREEMENT STATE REPORT - DAMAGED MOISTURE-DENSITY GAUGE

The following information was received via E-mail:

"On [6/8/19], Cal OES (California Office of Emergency Services) contacted RHB (Radiologic Health Branch) to report an incident regarding a damaged moisture-density gauge. The incident occurred on 6/7/19, at a temporary job site located at 1627 Fulton Road, Santa Rosa, CA. The gauge involved is a CPN Model MC1, S/N M13044837, containing 10 mCi of Cs-137 and 50 mCi of Am-241. The gauge was run-over by a construction vehicle at the job site. The gauge housing has been damaged and the user was unable to retract the source rod back into shielded position. The RSO contacted a gauge vendor, Pacific Nuclear Technology (PNT), and they immediately responded to the incident at the site. The gauge was secured by PNT and transported back to their storage for disposal. Leak test performed by PNT did not indicate any contamination. The RHB will be following up on this incident."

60-DAY OPTIONAL TELEPHONIC NOTIFICATION DUE TO INVALID ACTUATION OF A GENERAL CONTAINMENT ISOLATION SIGNAL

"This 60-day telephone notification is being made in accordance with the reporting requirements specified by 10 CFR 50.73(a)(1) and 10 CFR 50.73(a)(2)(iv)(A) to describe an invalid actuation of a general containment isolation signal affecting multiple systems.

"On April 30, 2019, at approximately 0650 CDT, a level 2 containment isolation signal was introduced when a fuse for the Nuclear Steam Supply Shutoff System was removed for a maintenance clearance. The level 2 containment isolation signal caused a trip of the Division I DC bus back-up charger, leaving only the Division I battery to carry the DC bus. At 0707 CDT the bus was de-energized when another unrelated clearance opened the battery supply breaker to the DC bus causing another containment isolation signal. This event did not affect Shutdown Cooling or any other protected Safety Related Equipment.

"The containment isolation signals caused an isolation of the systems listed below. All components that were not removed from service, gagged in position, already in the expected position due to plant conditions, or de-energized due to plant condition performed as designed.

"Containment Isolation valves for the following systems isolated as expected: Drywell and Containment Floor Drains, Drywell and Containment Equipment Drains, Condensate Makeup, Fire Protection Water, Service Air, Instrument Air, Reactor Water Cleanup, Spent Fuel Cooling and Cleanup, Reactor Plant Component Cooling Water, Chilled Water, Reactor Recirculation, Main Steam Drains, Reactor Building Ventilation, and Fuel Building Ventilation."

The licensee notified the NRC Resident Inspector.
