The Authority for Nuclear Safety and Radiation Protection (ANVS) has granted permission to Vrije Universiteit Amsterdam and concrete processing company Theo Pouw B.V. to decommission the cyclotron centre in the Maths and Physics (W&N) building on De Boelelaan in Amsterdam.
ANVS has also given permission for the concrete from the centre to be processed and reused. This means that the processing will result in as little waste as possible.
Radioactivity
Most cyclotrons in the Netherlands are used to make radioactive materials that detect cancer. Cyclotrons are installed in concrete bunkers to protect the surroundings from radiation released in the process. The concrete of the bunker will have become slightly radioactive through use. A permit had to be requested to ensure decommissioning and other work could be carried out safely. ANVS made a positive decision on the permit request. The cyclotrons that will be decommissioned have been replaced by new cyclotrons in the Amsterdam UMC Imaging Center. The production of the radioactive materials will also take place there soon.
Decommissioning
Radioactive metal and concrete will be released during the decommissioning of the cyclotron. Some of this material will be very slightly radioactive. This means that the decommissioning will not pose a danger to people at Vrije Universiteit Amsterdam or the immediate surroundings. The radiation that is released to the environment as a whole during decommissioning of the cyclotron is comparable to an X-ray at the dentist or a flight to southern Portugal.
Decommissioning of the cyclotron is part of the demolition of VU Amsterdam’s Maths and Physics building. Preparatory work is expected to begin in mid-2025. The entire process will be carried out diligently, in accordance with prevailing safety standards and with due care for employees, students and local residents.
