Event Notification Report for April 21, 2015

LOSS OF ASSESSMENT CAPABILITY DUE TO NON-FUNCTIONAL SEISMIC MONITOR LAPTOP

"Clinton Power Station (CPS) has completed a review of the station seismic monitor performance. The CPS seismic monitor laptop is currently operable; however, this review identified 3 times in the last 3 years that the seismic monitoring laptop was declared non-functional such that the capability to perform an EAL assessment in accordance with the Radiological Emergency Plan Annex would be adversely impacted. A loss of the seismic laptop computer prevents active seismic data from processing through the central recording unit and will not alarm in the main control room.
The seismic monitor laptop became non-functional and unresponsive on the following dates:

1) January 4, 2013
2) July 19, 2013
3) November 2, 2014

"The loss of assessment capability is reportable to the NRC within 8 hours of discovery in accordance with 10 CFR 50.72 (b)(3)(xiii) This report is required per 10 CFR 50.72(1)(1)(ii) as an event that occurred within 3 years of the date of discovery."

The NRC Resident Inspector has been notified.

Notified the R3DO (Valos).

AGREEMENT STATE REPORT - RADIOGRAPHY TRUCK ACCIDENT RESULTING IN A FATALITY

The following information was received by the State of Texas via email:

"On April 21, 2015 at 2209 [CDT] hours, the Agency [Texas Department of State Health Services] was contacted by Andrews County Emergency Management (ACEM). They informed the Agency that an accident had occurred 12 miles south of Andrews, Texas, on highway 385, which involved a radiography truck. The Agency contacted ACEM chief who stated he was at the scene of a three vehicle accident which included a truck from Desert NDT. The driver was killed in the accident and the truck cab had separated from the frame. He stated the dark room had separated from the truck bed. He stated a person from the Andrews County WCS [Waste Control Specialist] was there and had performed a radiation survey and measured a dose rate of 15 millirem 10 feet from the truck. He stated the licensee had been contacted. He stated they had taken care of the survivors and had backed out of the area until the licensee's radiation safety officer arrived on the scene. He stated they had not seen the shipping papers, only the radiation symbol on the truck. I asked him to have the licensee contact the Agency as soon as they arrived on site.

"The licensee's (Desert NDT) RSO arrived at the scene at 2223 hours and contacted the Agency. He stated his priority was to locate the source. He agreed to call the Agency as soon as he had control of the source.

"At 2240, the RSO contacted the Agency and stated he had control of the source. The iridium source was inside a INC 100 radiography camera and the RSO believed the activity was between 20 and 26 curies. He stated the camera did not appear to be damaged. He stated the dark room had separated from the truck and split into two pieces. The camera was located still in its transport box in a section of the darkroom. He stated the dose rate on contact with the camera was 16 millirem an hour and 0.4 millirem at 1 foot. The dose rate at 1 meter was not distinguishable from background. He stated no individual at the scene would have received an exposure to radiation that would have exceeded any limits. The RSO stated he was taking the source back to the licensee's office for storage. The RSO stated they would send the exposure device to the manufacturer for inspection.

"Additional information will be provided as it is received in accordance with SA-300."

INOPERABLE SECONDARY CONTAINMENT

On April 21, 2015 at 2258 [EDT], Secondary Containment became inoperable requiring a Technical Specification 3.6.4.1 entry for failure to meet SR 3.6.4.1.1 on Unit 1 and Unit 2.

The inoperability was caused by Zone 3 differential pressure lowering to less than 0.25 [inches Water Column] when Zone III fans tripped during 30mph wind gusts.

Fans were restarted and differential pressure restored to greater than 0.25 [inches Water Column] at 2314 hrs. April 21, 2015.

This event is being reported under 10 CFR 50.72(b)(3)(v)(c) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment system.

The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION DUE TO WORKER FATALITY NOT RELATED TO PLANT OPERATION

"At approximately 2330 [EDT] on April 21, 2015, a worker collapsed in the turbine building inside the protected area. Initial response by on-site responders found the person unresponsive. Subsequent response by off-site medical responders determined the person had died and the station was notified at approximately 0130 on April 22, 2015. The fatality was due to an apparent personal medical issue and not work related . The individual was not contaminated. The individual was transported off-site via onsite Site Protection personnel. Plant operation was not impacted by the event."

The licensee informed Lower Alloways Creek Township and will inform the NRC Resident Inspector.

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.
