| Event Text AGREEMENT STATE REPORT - UNPLANNED CONTAMINATION EVENT
The following was received by fax from the Tennessee Division of Radiological Health:
"While emptying a 55 gallon drum of lead for reuse into a B-12 box, unknown and unsuspected contamination levels in bottom of drum resulted in a contamination of the area to max levels of 2,000,000 dpm/100 cm2 beta. Contamination levels in drum determined to be 2,000,000 dpm/100 cm2 max post event. Pre job surveys identified no elevated contamination levels in top of drum. Isotope and activity are unknown at this time. Isotope is a weak pure beta emitter. Analysis is underway for isotopic determination. [Three] 3 persons with skin contamination were deconned. Bioassays are underway for internal dose assessment. Area is being recovered, however, not within 24 hours resulting in reporting of event. Dose assessments are forthcoming."

| Event Text AGREEMENT STATE REPORT - POTENTIAL EXCESSIVE EXPOSURE OF RADIOGRAPHER
The following report was received from the Louisiana Department of Environmental Quality via facsimile:
"On October 4, 2016, at approximately 0910 CDT, the Radiation Safety Office of CB&I Walker LA, LLC notified LDEQ [Louisiana Department of Environmental Quality] of a potential excessive exposure to a radiographer working in the licensee's permanent radiographic facility. After making a proper radiation survey, the above radiographer moved his exposure device with 100.6 Ci of Ir-192 and then noticed the rear fitting had come loose from the crank-out control, which showed approximately three inches of drive cable exposed. The radiographer pushed the fitting forward and tightened it back into the connector of the crank-out control. The licensee believes that at this point the source was inadvertently pushed out of the front of the camera approximately three to four inches. The radiographer did not notice this at the time and continued setting up for the next exposure.
"Upon exiting the shooting cell, the radiographer observed the red revolving warning light. The radiographer also observed sounding of the shooting cell alarm upon his exiting the cell. The radiographer stated that he was inside the shooting cell for a period of between five to seven minutes. The radiographer read his direct reading pocket dosimeter and observed an off-scale reading. The radiographer immediately notified his RSO [Radiation Safety Officer], who immediately sent his whole body badge in for rush processing subsequent to the dosimetry processor being notified by the RSO. The RSO used the radiographer's information of occupancy time and his statement that he was standing while the exposure device was stationed on the shooting cell floor throughout the incident to estimate the radiographer's whole body exposure of between 5 and 25 R. The radiographer was then immediately sent to a local medical laboratory to have his blood drawn. There is no potential for off-site exposure. The licensee was advised by this inspector to contact the REAC/TS facility for guidance on blood chromosomal analysis. This is a preliminary report in an on-going investigation."

| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text UNANALYZED CONDITION DUE TO FAILURE OF A WATERTIGHT DOOR TO CLOSE
"At 0938 [EDT], the watertight door in the Unit 1 Inboard Service Water Penetration Area was unable to be closed. The watertight door serves as a High Energy Line Break (HELB) and Medium Energy Line Break (MELB) barrier between the mechanical penetration room and the service water penetration room. A HELB/MELB event occurring in a room with its barrier door open could adversely affect equipment in an adjacent room. Consequently, a HELB/MELB event could have rendered equipment in the adjacent room inoperable.
"At 1005, station maintenance was able to successfully close and latch the door restoring the barrier.
"This event is being reported under the requirements of 10CFR50.72(b)(3)(ii)(B) as, 'the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety.' An ENS notification is required if an unanalyzed condition occurred within 3 years of the date of discovery even if the event is not on-going at the time of discovery."
The licensee notified Lower Alloways Creek Township and the NRC Resident Inspector. | |
