AFRY Real Digital Twin makes the decommissioning of nuclear power safer

AFRY X has signed an agreement with OKG in Oskarshamn, Sweden, to help the client decommission, moving logic to a new control room. The tool used is AFRY X Real Digital Twin (RDT), a software solution that creates an exact replica – a digital twin – of equipment and components.     

The reactors O1 and O2 have been shut down since 2017, and during the last year, OKG began moving logic from the old control room to a new location. To carry out the decommissioning in a safe and controlled manner, OKG uses RDT as virtual test bed before making any changes linked to the dismantling of the production systems. The goal is to increase the security level during disassembly, while at the same time being able to shorten the test period by evaluating different scenarios in a virtual copy. It is an exciting breakthrough deal in the energy sector where nuclear power in particular has very high demands on safety.    

 “This is the most exciting part for our client, OKG. AFRY’s Real Digital Twin really works, and you can manage to solve the most problems before it has happened, all for saving time and money,” says Andreas Buhlin, Product Manager AFRY X. 

“For us, the use of the digital twin is an exciting tool that can cut a lot of time in the maintenance work, for example when testing new code, while we see great value of it works as it is intended when we implement a change in our systems,” says OKG.

Decommissioning of nuclear power is a hot topic and it have been so since the Swedish Parliament decided to shut down almost all reactors in Sweden.
