Event Notification Report for May 06, 2013

ONE OF TWO NATIONAL WEATHER SERVICE TONE ALERT RADIOS OUT OF SERVICE

"At 10:16 AM EDT on May 6, 2013, the National Weather Service (NWS-NOAA) reported a loss of the [NWS-NOAA] Tone Alert Radio Transmitter, WXL-58 located in Chapel Hill, North Carolina, which serves the Northeast Piedmont on 162.550 MHZ. The NWS-NOAA does not have an expected return to service time. The NWS-NOAA Tone Alert Radio Transmitters are in place to provide a redundant means to alert residents within five miles to an emergency at the plant. Eighty-three Alert and Notification System (ANS) sirens are located throughout the ten mile radius of the plant. The ANS sirens have the same function as the Tone Alert Radios, but extend out to ten miles.

"All ANS sirens are currently in service and fully functional. Therefore, there is a means to alert the public within the 10 mile radius of the plant if an actual emergency were to occur. There is no impact to public health and safety due to this condition.

"The NRC Resident Inspector has been notified."

This report was also made per a requirement of licensee procedure PLP-201.

AGREEMENT STATE REPORT - SOURCE SHIPMENT DID NOT ARRIVE AS EXPECTED

"QSA Global reported a lost source. The location of the source is not known. The shipment contains Ir-192."

QSA expected this source to arrive at their Baton Rouge, LA location at about 0800 CDT on 5/6/13. QSA contacted the common carrier to locate the item at some time after that. The last known location was Memphis, TN.

* * * UPDATE FROM MIKE FULLER (QSA) TO PETE SNYDER AT 1915 ON 5/6/13 * * *

At about 1915 EDT, QSA personnel learned from the common carrier that the item had been located at the Memphis, TN shipping location.

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL

Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

TECHNICAL SPECIFICATION SHUTDOWN REQUIRED DUE TO NON-FUNCTIONAL CLASS 1E AIR CONDITIONING UNIT

"Class 1E Air Conditioning Unit SGK05A cools safety related electrical Train 'A' and was declared non-functional at 1733 hours. As a result, the following safety related electrical equipment was declared inoperable: 4.16 KV Bus NB01; 480 volt buses NG01 and NG03; 120 volt Instrument AC inverters and buses NN11, NN13, NN01 and NN03; 125 VDC chargers and buses NK11, NK13, NK01 and NK03. T/S 3.0.3 was entered at 1733 from T/S 3.8.7 due to two out of four 120 volt AC inverters (NN11 and NN13) being inoperable. Plant shutdown to Mode 5 commenced at 1801 hours.

"All electrical systems listed above remain functional but are declared inoperable due to inadequate room cooling capability."

The licensee plans on performing a controlled plant shutdown using normal rod insertion following approved plant procedures. Per the licensee, Mode 3 conditions must be met by 0033 CDT 5/7/2013 and Mode 5 conditions must be met by 0033 CDT 5/8/2013.

The licensee notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - STUCK RADIOGRAPHY SOURCE

The following information was received via E-mail:

"Licensee reported a stuck radiography source that occurred at approximately 2315 CDT on May 6, 2013. Licensee's RSO [Radiation Safety Officer] responded to incident site, increased barricades, maintained perimeter, and notified Chevron RSO. Licensee's source was fully retracted into the shielded position at 0100 CDT [on May 7, 2013]. The Licensee's RSO received 20 mR conducting the source retrieval."

The incident occurred while performing work at the Chevron Pascagoula Refinery.

Mississippi Report Number: MS-13002

* * * UPDATE RECEIVED FROM JAYSON MOAK TO JOHN SHOEMAKER ON 5/17/13 AT 1250 EDT * * *

The following report was received via e-mail:

"On 5/6/2013, the Licensee had a two man crew performing industrial radiography at the Chevron Plant. The radiographer was unable to crank the source back into the camera after his third exposure. The source was then cranked back into the collimator. The radiographer repositioned the cranks and tried to retract the source again without success. The radiographer and assistant radiographer extended the restricted area boundary and called the Licensee's night safety officer on site. The Licensee's RSO then notified Mistras Group's CRSO [Corporate Radiation Safety Officer] and plant personnel of the incident.

"The Licensee's RSO, once on site, discovered from conversation with the radiographer that the drive cable was hitting a melted area of the conduit and not letting the drive cable pass through. The melting of the (black) return conduit of the cranks occurred because it was placed over a non-insulated pipe from the plant's furnace. The Licensee's RSO made the decision to cut the conduit at the melted area of the cranks to save time and reduce exposure while trying to retract the source. This provided clearance for the drive cable to pass through and allowed the source to retract back into the fully shielded position inside the camera. The camera, guide tube, and cranks were surveyed by the RSO upon source retraction."

The State (Mississippi) has closed this case.
