Decommission history

The radiochemistry lab:

The radiochemistry lab was decommissioned first, here there were chemicals, radiation sources and radioactive contamination which required an approach different from the rest of decommissioning.

The accelerator plant:

With experience from the decommissioning of the Radiochemistry Laboratory, we then set out on the Accelerator facility. Here we found no contamination, but on the other hand, all the equipment inside the experimental premises has been exposed to radiation. Before this equipment can leave the facility, it must therefore be assessed, control measured and declassified. This is a complicated and time-consuming process as methods to accomplish this must be developed first.

Waste disposed:

We have exempted, in some cases declassified and released a large amount of waste. Including:

• leftover equipment -> Surplus
• "blue" waste = clean -> different fractions conventional waste
• concrete in various forms (approx. 700 tons)
• cables in different shapes (approx. 12 tons)
• plaster from partition walls

Opening up discharge routes:

In order to be able to get all the equipment and all the waste out, we have worked on opening up ways out. This has meant that we have moved equipment, demolished walls and carried out waste.
