Chernobyl, 40 years on: from nuclear disaster to scientific knowledge base
For forty years now, Chernobyl has been synonymous with the worst civil nuclear disaster in history. The accident in reactor 4 remains a crucial reference point for radiation protection and nuclear safety. In a comprehensive web dossier, the experts at SCK CEN bring together the scientific lessons learned from the disaster, to which the research centre itself has been actively contributing for decades.
The facts, not fiction
In this web dossier, we present the facts. We outline the causes and consequences of the accident. What is the situation in Chernobyl today? And what does the future hold?
As Belgium’s centre of expertise for nuclear research, SCK CEN played a key role in measuring, analysing and interpreting radioactive contamination across Europe. To this day, we continue to carry out impact studies and measurements, both through international monitoring networks and through targeted field campaigns in and around Chernobyl. This data forms the basis for reliable risk assessments of exposure and health effects.
The report also highlights how the accident led to fundamental improvements in nuclear emergency planning, regulation and reactor safety. In Belgium, SCK CEN contributed to the establishment of a scientifically sound emergency response organisation and to the development of expertise in dosimetry, reactor design and protection against external risks.
We also focus on reactor design and how crucial this is for safety. The Soviet RBMK reactors were inherently less safe than the PWR reactors in Western Europe. Our experts explain this difference and outline how SCK CEN focuses on research, development and demonstration of even safer reactors.
Understanding the past to look to the future
With this web dossier, SCK CEN emphasises that Chernobyl was not an end point, but a starting point for scientific progress. Through measurement, modelling and knowledge-sharing, the centre continues to contribute to a higher level of nuclear safety, both today and in the future.
