AGREEMENT STATE REPORT - EXTREMITY OVEREXPOSURE WHILE OPERATING A RADIOGRAPHY CAMERA
The following report was received from the Texas Department of State Health Services via email:
"On March 25, 2015, the licensee reported that on March 15, 2015, one of its industrial radiographer trainees had experienced a possible overexposure to his right hand while using a QSA Model 880 camera that contained a 54.5 curie iridium-192 source. Initial information reported by the licensee: Following the 10th and final exposure of the day, the radiographer trainee climbed a ladder to the first deck and approached the camera from the rear with a survey meter. He performed a 360 degree survey of the camera and full length of the guide tube noting a zero reading on the survey meter. He then attempted to disconnect the guide tube by attempting to rotate the outlet port cover. When it would not rotate, he looked at the back of the camera to ensure the selector was in the correct position, and then attempted to disconnect the guide tube a second time. Again, the outlet port cover would not rotate and he looked at the back of the camera and noticed the slide bar of the lock was showing red, indicating the source was not in the fully shielded and secure position. He climbed down the ladder and informed the radiographer trainer what had happened.
"The radiographer trainer exposed the source approximately 1/4 turn and forcibly retracted it to its fully locked and shielded position. They checked the survey meter (battery function check) and determined it was not working properly. The meter was disassembled, battery terminals were adjusted, and the meter functioned properly.
"The radiographer trainer surveyed the camera and determined the source was fully retracted. The radiographer trainee stated he did not hear his alarming rate meter due to the noise level at the job site. The radiographer trainer did not receive any additional exposure as a result of this event. The radiographer trainee's pocket dosimeter was off-scale. His dosimetry badge was sent for processing and from the results the licensee determined he had received 384 millirem whole body dose from this event. Calculations will be made following a re-enactment of the event on 03/30/2015 to determine the dose to his hand.
"Exposure Device: QSA Model 880D SN: D1123, Source: 54.5 curies iridium-192 SN: 14191G"
The State of Texas is continuing to investigate the issue.

PLANT SHUTDOWN DUE TO FAILURE TO RESTORE CONTAINMENT FAN COOLER UNIT
"This 4 hour notification is being made pursuant to the requirements of 10 CFR 50.72(b)(2)(i), for 'The initiation of any nuclear plant shutdown required by the plant's Technical Specifications'.
"Salem Unit 1 has initiated a unit shutdown at 1227 [EDT] in accordance with Technical Specification Action Statement 3.6.2.3, Action A, for inoperability of the 14 Containment Fan Cooler Unit. Technical Specification 3.6.2.3, Action A requires that with one or two Containment Fan Cooler Units inoperable, operability must be restored within 7 days, or be in at least Hot Standby (Mode 3) within the next 6 hours and in Cold Shutdown (Mode 5) within the following 30 hours.
"The 14 Containment Fan Cooler Unit was declared inoperable on March 8, 2015, at 1158 EDT, following a trip of its low speed breaker on thermal overload during a scheduled surveillance test.
"13 Chiller is tagged for scheduled maintenance.
"The NRC Resident Inspector has been notified."
Unit 1 is proceeding to Mode 5. There is no effect on Unit 2.
The licensee will notify the Lower Alloways Creek Township, the State of New Jersey, and the State of Delaware.
