AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following information was received from the State of California via email:

"On 11/17/17, the RSO [Radiation Safety Officer] contacted RHB [CA Radiologic Health Branch] to report a stolen moisture density gauge. The stolen gauge is a CPN Model MC-1DR, S/N MD90209216, containing 10 mCi of Cs-137 and 50 mCi of Am-241. The user had taken the gauge home and left it secured in the back of his truck. The truck was parked at his residence . . .. According to the user, most likely between midnight and 5 AM of 11/17/17, the chain locking the gauge to the truck bed was removed and the case was dragged behind a building where the locks on the box were broken and the gauge was removed. The box was recovered without the gauge. [The] RSO had notified San Jose Police Department of this incident (Event # P173210429). RHB will be following up on this investigation.

"5010 NUMBER (Date Notified): 111717"

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 - RADIOGRAPHY TRAINEE OVEREXPOSURE

The following report was received via e-mail:

"On November 28, 2017, the Agency [Texas Department of State Health Services] was contacted by the licensee's Radiation Safety Officer (RSO) who reported that on November 28, 2017, they were notified by their dosimetry processor that one of their radiographer trainee's exposure badges was reported to read 62 Rem. The RSO stated the trainee was returning to the Longview office from West Texas to be interviewed. The badge reading was for the month of October 2017. The RSO stated the trainee had operated the radiography camera crank out device, but had not changed out any film. It is believed the dose is to the badge only. The RSO stated they had not observed any adverse health effects in the trainee. On November 29, 2017, the Agency contacted the RSO and requested additional information. The RSO stated the trainee stated that they had not dropped their dosimeter and accidently exposed it. The trainee had stated that they had been wearing an alarming rate meter and it had never alarmed. The trainee's daily exposure record did not indicate any abnormal exposures. The radiographer supervising the trainee did not recall any abnormal operations while supervising the trainee. The RSO stated the trainee had not received any type of medical treatments during the exposure period. The RSO stated they were considering sending blood samples to REAC/TS for analysis. The RSO stated the dosimetry processor reported the exposure to the badge was angular. The RSO stated the trainee has been assigned duties that would not give them any additional exposure.

"The licensee will provide the Agency [Texas Department of State Health Services] any information gathered in the interview with the trainee. The RSO cannot state with certainty that the exposure is not real, therefore the Agency is providing this report to the Nuclear Regulatory Commission. Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - TWO NUCLEAR GAUGES INVOLVED IN FIRE

The following report was received via E-mail:

"On November 30, 2017, the Agency [Texas Department of State Health Services] was notified by the licensee's consultant that two nuclear gauges were involved in a fire on November 28, 2017. The consultant stated they could not gain access to the gauges until this date. The gauges are Thermo Fisher model 5203 gauges containing a two (2) curie (original activity) cesium-137 source. The consultant stated the dose rate on one of the gauges was reading 180 millirem an hour on a preliminary radiation survey. This dose rate appears to be higher than normal. A contamination survey was performed in the area of the gauges, but the results were not available at the time of the report. The gauges are located 20 - 30 feet above the ground and do not create an exposure risk to any individuals. Additional information will be provided as it is received in accordance with SA-300."

Texas Incident #: I-9524


* * * UPDATE AT 0740 EST ON 12/1/2017 FROM ART TUCKER TO MARK ABRAMOVITZ * * *

The following information was received via E-mail:

"The licensee has provided the following additional information:

"The source holders are visibly intact, however they are black with soot. Both of the gauges were surveyed. For B-1228 the readings are normal but B-1227 has a localized spot on the lower left-hand location of the shield where the readings are 180 mR/hr at contact and 14 mR/hr at 1 ft. Additional shielding has been attached to the lower left hand location of the shield to reduce the dose rate to 3 mR/hr at 1 ft. Sealed Source leak tests have been performed and the results will be communicated as soon as they are assayed. No personnel (member of the general public or radiation workers) have been within 5 feet of either source due to the unsafe structural conditions due to the fire. Additional information will be provided as it is received in accordance with SA-300."

Notified the R4DO (O'Keefe) and NMSS Events Notification (via e-mail).


* * * UPDATE FROM ART TUCKER TO DONALD NORWOOD AT 1511 EST ON 12/1/2017 * * *

The following information was received via E-mail:

"The licensee reported that the results of the leak test performed on the two gauges indicated the sources were not leaking (less than 0.0001 microCi). Additional information will be provided as it is received in accordance with SA-300."

Notified the R4DO (O'Keefe) and NMSS Events Notification (via e-mail).

OFFSITE NOTIFICATION OF GROUNDWATER RESULTS TO STATE AND LOCAL AGENCIES

"This non-emergency notification is being made in accordance with 10 CFR 50.72(b)(2)(xi), any event or situation related to the protection of the environment for which notification to other government agencies has been made. Dominion Energy is in the process of informing the Virginia Department of Health, Department of Environmental Quality, Department of Emergency Management, and the Surry County Administrator of recent groundwater monitoring results at Surry Power Station in accordance with NEI 07-07, Industry Groundwater Protection Initiative (GPI).

"On December 6, 2017 at 1138 EST, Surry Power Station received analysis results of recent samples from the on-site groundwater monitoring program. As part of the program, 10 new groundwater monitoring wells were recently placed in service within the Protected Area to provide early detection, to better define the site's hydrology, and if necessary, to mitigate any potential leaks. The analysis results from one of the new wells indicated tritium activity level above the GPI communication threshold. Samples were re-analyzed, resulting in different values, with the highest result of 59,300 picoCuries per liter. Since each result was above the voluntary reporting threshold, Surry stakeholder communication was implemented in accordance with the NEI GPI Voluntary Communication Protocol, Criterion 2.2.

"There are no known active leaks at this location; however, Dominion Energy is continuing to investigate the source of the tritium and the reason for the variability in the sample results.

"Tritium was not detected in the on-site monitoring locations outside of the Protected Area. No tritium has been detected in the on-site and off-site drinking water wells. Since the activity is contained within the site restricted area, the health and safety of on-site personnel and members of the public are not affected.

"A 30-day report will be submitted to the NRC in accordance with NEI 07-07.

"The NRC Senior Resident Inspector has been notified."
