SCK CEN: Introduction

Sat, 16 May 2026 00:00:00 GMT

There is a reactor in the Belgian Campine that runs on five hundred watts - less than the espresso machine in your kitchen. It is called VENUS, and it sits inside one of Europe's most concentrated clusters of nuclear research, hidden in pine woods at the edge of Mol. The center began in 1952, when a country newly out of war and newly rich in Congolese uranium decided it wanted to be at the front of the atomic age. What has grown there in the seventy years since is one of the strangest scientific campuses in Western Europe: a place where employees once lived in a custom-built neighborhood called the Atoomwijk, where a fast-spectrum reactor unlike any on the planet is being engineered to swallow nuclear waste, and where the BR2 reactor still makes the radioactive isotopes that, somewhere in the world right now, are being injected into someone's veins to find their cancer.

SCK CEN: Four Reactors in Eight Years

Sat, 16 May 2026 00:00:00 GMT

Between 1956 and 1964, SCK CEN - then known by the unwieldy Dutch acronym STK - brought four nuclear research reactors online. BR1 came first, then BR2, then BR3, which in 1962 became the first pressurized water reactor in Europe. VENUS followed in 1964. By 1963 the center employ...

SCK CEN: The Reactor Run by a Particle Beam

Sat, 16 May 2026 00:00:00 GMT

Most reactors are critical assemblies - tuned to sustain their own chain reaction, regulated by control rods that absorb just enough neutrons to keep the fission steady. MYRRHA, the Multi-purpose hYbrid Research Reactor for High-tech Applications, is being designed to do somethin...

SCK CEN: The BR2 and the Medicine in Your Arm

Sat, 16 May 2026 00:00:00 GMT

BR2, the second of the original quartet, is still running. Its strange flower-shaped core, with channels arranged in a tilted helix, makes it one of the highest-flux research reactors on earth, and one of the world's main producers of medical radioisotopes. Technetium-99m, luteti...

SCK CEN: The Awkward Past

Sat, 16 May 2026 00:00:00 GMT

Not every page of the institute's history is clean. In the 1980s, SCK CEN employees were bribed by a West German firm, Transnuklear, to receive and store high-level nuclear waste they should not have accepted. The scandal made international headlines and contributed to Belgium's ...

SCK CEN: Watching the World's Air

Sat, 16 May 2026 00:00:00 GMT

Outside one of the laboratories at Mol, a 121-metre guyed mast rises above the pines - tall enough to read weather above the treetops. Nearby, a sampling system called Snow White draws huge volumes of air through filters each week, hunting trace radioactivity. It is sensitive eno...
