THEFT OF RADIOACTIVE SOURCES

On the night of October 8, armed thieves entered the storage facility at the company and equipment and various electronic ítems were stolen, as well as two sources of Am-Be 185 GBq each (Category 3), within a yellow container.
The company notified the National Police and the IPEN (regulatory body), who sent a team for performing a quick search of the sources in the area.
Local advisory warnings to the public were issued.

Theft of portable radioactive gauge

On June 17th, 2012 a portable radioactive gauge was stolen from the store room of BISA company, in a mining plant. The radioactive gauge was used to density and moisture measurements and it was stolen jointly with other belongs from company by breaching the store room door.
The radioactive gauge is a TROXLER manufactured and model 3440P and serial 65350. It contains two Category 4 radioactive sources: Cesium-137 (296 MBq) and Am-241/Be (1,48 GBq).

Exposure to workers

On the morning of 14 February 2014, a radiography company was performing non-destructive testing by industrial radiography with a 1,22 GBq Ir-192 source to several pipe joints in a chemical plant. The operations were performed by three operators (A, B and C) in a platform at nearly 12 meters height over the floor. In order to reduce the level of radiation in the area a tungsten collimator was fixed at the tip of guide tube.

Overexposure of radiographers

During radiographic operations performed by two radiographers the guide tube was squashed so the Ir-192 source could not be retracted to the gamma projector. Operations were being performed at 6 m height. The operator tried to correct this situation using a plier to strainghten out the guide tube but unsuccesfully . Then the guide tube was cut and the Ir-192 source was recovered using tongs and shieldings. The workers took personnel dosimeters, alarm dosimeters and detectors but radiation protection officer was absent.

EU calls for more nuclear tests after Belgian fears

Friday, August 10, 2012

The discovery of possible cracks in a Belgian nuclear reactor should trigger urgent testing around the EU, but such decisions are for national governments to take, a European Commission spokeswoman said on Thursday.

"National authorities will conduct tests, that seems obvious," said Marlene Holzner, spokeswoman for EU energy commissioner Guenther Oettinger. "The European Commission can make recommendations, but it can't make them binding," she stressed.

Accident in industrial radiography

A radiographer was taking several radiographic films to a pipes by the night. In order to be sure that the guide tube was correctly the radiographer went to the tube guide an collimator to fix them. This operation was made by 40 times. Eventually the radiographer touched with his left hand, at least 10 times, the tube guide where the source was unnoticed. Also, two auxiliar staff went to the radiographer position carrying the films to be checked at least by 40 and 20 times. The radioactive source was 3199,5 GBq Ir-192. The event was detected at the end of job.

Potential Overexposure During Co-60 Source Exchange

On July 21, 2008, two radiation workers, A and B, one American and one Brazilian, respectively, had received a potential overexposure. While in a hospital in the State of São Paulo, Brazil, they were in the process of exchanging an expended cobalt-60 source with a new cobalt-60 source. After engaging the source holder with the removal tool, worker A transferred the source holder from the unit head into the transfer cask. Once the source holder was in the transfer cask, worker A continued making preparations to complete the removal sequence.

TURBINE TRIP AND MANUAL SCRAM DURING NORMALIZATION OF A HEAT EXCHANGER OF THE MAIN OUTPUT TRANSFORMER

On December 15th, 2007, while putting in service a heat exchanger of the main output transformer, after its reparation, the actuation of the protection of the block occurred, producing a turbine trip and electric commutation on the start up line. After that a manual SCRAM was needed according to the operating instruction, not being able to normalize the Electric System in the required time.

Steam Generator tube leakage at Atucha N.P.P

On March 16, 2007, Atucha NPP, was shutdown due to a steam generator tube failure (SG # 2). The plant remained in cold shutdown, for 9 days, starting up on March 25, 2007.The Total Activity released was less than 20 % of the monthly allowed derived limit for discharge. The mentioned event was not considered safety significant, however, it was assumed reportable because of “degradation of in-depth defense”.
