KEMA Suspensie Test Reactor

The KEMA Suspensie Test Reactor is a nuclear research facility featuring an unusual design where tiny uranium particles are suspended in water, functioning as both coolant and moderator simultaneously. The laboratory building was designed by architect G. Hamerpagt and incorporated safety features tailored to the specific demands of nuclear reactor operation.

The reactor laboratory opened in 1958 with Prince Bernhard presiding over the inauguration, marking an important turning point in Dutch nuclear energy research. The project emerged during a period when many European nations were exploring nuclear energy possibilities.

The facility demonstrates Dutch commitment to nuclear science and attracted researchers from across Europe interested in learning about innovative reactor technology. Visiting scientists found it important as a center where different countries could exchange technical knowledge.

The site is located in Arnhem and serves as a historical research building that shows how early nuclear facilities were designed. Visitors should understand it is a place of specialized technical interest where the architecture reflects both safety and scientific function.

The reactor used microscopic uranium particles suspended in a homogeneous mixture, quite different from traditional reactor designs. This approach allowed for more even heat distribution throughout the cooling medium.
