Overexposure to Radiographer’s Assistant |
On April 16, 2012, the licensee radiographer’s assistant informed the licensee Radiation Safety Officer that his pocket dosimeter had gone off scale 10 days prior. The licensee sent the radiographer’s permanent badge for processing and the result was a 250 mSv (25 rem) whole body dose reading. The State of Florida was informed of the dose on April 24, and has verified the dose. The State of Florida continues its investigation.

Loss of shutdown cooling due to station blackout during refueling outage |
On February 9, 2012, during a refueling outage, loss of off-site power (LOOP) occurred and emergency diesel generator (EDG) 'B' failed to start while EDG 'A' was out of service for scheduled maintenance, resulting in a station blackout (SBO). Off-site power was restored 12 minutes after the SBO condition began.
The LOOP was caused by a human error during a protective relay test of the main generator. The EDG 'B' failing to start was caused by the failure of the EDG air start system.

Fire and abnormal primary circuit leak occured at Penly NPP n°2 reactor |
On 5 April 2012, at around 12 midday local time, ASN was informed by the operator EDF that a fire had started in the n°2 reactor building of the Penly NPP (North-West of France). The reactor automatically shut down.
EDF teams and the local firemen brigades entered the reactor building and extinguished burning oil. The firemen ensured the fire was totally extinguished.

Overexposure to Radiographer |
During work activities, a licensee’s radiographer [Radiographer A] appears to have been overexposed while carrying a guide tube that contained a 2.405 TBq (65 curies) Ir-192 source. Radiographer A was conducting work activities on a platform. When he had completed the series of shots, he signaled to Radiographer B, on the deck below, to crank in the source. Radiographer A surveyed the camera and then disconnected the source guide tube and laid it on the scaffold while he lowered the camera.

Spillage from water pipe in the room with nuclear materials |
Due to low temperatures, in February, the spillage from water pipe occurred in the Vinca Institute in the room with the nuclear materials under the Safeguards control. All nuclear materials remained secured at the same place. The water was collected from the floor, sampled and analyzed. During this event there were no exposures of the workers and the public. There is no dicharges to the environment.

Failure of the reactor component cooling water system and others by tsunami |
Unit 2 of the Onagawa Nuclear Power Station started operation since 14:00 on March 11, and the Tohoku District – Off the Pacific Ocean Earthquake occurred at 14:46 on the same day. The reactor was automatically stopped and emergency diesel generator A (EDG (A)), emergency diesel generator B (EDG (B)), and high-pressure core-spray diesel generator (EDG (H)) automatically started.

Am-241 source melting |
An orphan Am-241 source inadvertently included in scrap metal was melted on the //23/2/2012 // in a Finnish steel factory in Tornio. The first alarm of abnormal radiation level was given by detectors screening the slag pots. The activity of melted source can not be determined exactly, but it is estimated to fall in to Category 4 (0,6 – 60 GBq). The source is traced by the operator to stainless steel scrap delivered from Central Europe.
Due to its physical properties most of the Am-241 activity is partitioned in to the slag phase (aprox 99%) and dust phase (1%).

Overexposure to Radiographer |
A licensee radiographer was performing radiography using a QSA D880 radiography camera containing a 1.37 TBq (37 curie) Ir-192 source. The radiographer approached the guide tube without verifying that the survey meter was functioning. When the radiographer attempted to crank the source out through the guide tube, the radiographer discovered that the source was already fully cranked out. The radiographer then cranked the source back into the body of the radiography camera and notified the Radiation Safety Officer (RSO).

Overexposure of a worker in a lead foundry |
In a lead foundry, a foundryman extracted lead by heating from a shielding heads of a radiotherapeutic unit. Before the lead extraction he dismantled the heads not knowing that inside one of them was a radioactive source left. Than he carried out a tube with the source. The tube with the source was left in the room. The following day (10th January) morning, the foundryman continued the work preparing for the lead extraction (for about 2 hours).

Level 2 incident on INES scale concerning a pipe nonconformity in two Cattenom NPP fuel storage pools |
On 18 January 2012, Cattenom's operator (EDF) notified ASN that the absence of a \siphon breaker\ orifice on the fuel storage pools of reactors 2 and 3 had been detected during an inspection performed by EDF teams.
