Fuel fail and emission from research reactor

Fuel rods were unloaded October 17 2016, and placed in an open container in the handling compartment. The reactor was then in shutdown. On October 20th increased levels of noble gasses were detected in the filters from the handling compartment. The fuel in the handling compartment was inspected and several faults on fuel rods were detected.
These were moved to a storage container on October 24, however the container was discovered to not be leak tight. The levels of I-131 and I-132 in the Reactor hall were still increasing.

Electronic Personal Dosimeter went into Alarm during X-ray Radiography Operations

Radiographers were working in a cell in a redundant reprocessing facility, carrying out digital imaging of legacy crates using X-rays in order to identify their contents.
This cell is an area of known high background radiation containing ten legacy crates.
A previous health physics survey of the crates had identified radiation levels in nine of the crates between 0.5 mSv/h and 1.8 mSv/h gamma, with the other crate up to 20mSv/h gamma.

Inadvertent damage of a Se-75 source

On December the 12th, 2016, a Se-75 source was inadvertently damaged during re-pair work on faulty radiography equipment. The work was performed in Düsseldorf region in North Rhine-Westphalia by a specialized company within a controlled area. The source contained about 1.3 Terabecquerel Se-75. The radioactive substance was released during the repair work and contaminated persons and zones within and out-side of the controlled area. Besides the two workers performing the repair work, other persons were also contaminated.

Cyclotron operated with an open bunker door

On the 12th of October 2016 the Swedish Radiation Safety Authority was informed about an event that occurred on the 7th of October where a cyclotron was operated with an open bunker door. The licensee is authorised to produce short lived isotopes used for medical
diagnostics. The bunker is supposed to be sealed with interlocks preventing operation of the cyclotron with an open door. At the time of the event a study visit was performed at the facility by hospital personnel from the whole of Sweden lead by a representative from

Loss of radioactive source (Co-60, Pomina, 2015)

The loss of radioactive source originated from liquid steel spill accident during steel billet manufacturing process of the factory at the beginning of September, 2014. In the accident, lead layers for radioactive source protection were damaged. The radioactive source was Co-60, its activity at this time was 2,33 mCi. After the damage had been detected, the technical team had removed the box for maintenance. The technical team proposed that the source should be isolated because its safety was not ensured.
