The TRIGA Mark II reactor has been operational at JSI since 1966, and its main purpose is to serve the scientific community by enabling neutron and gamma-ray research, the production of radioactive isotopes, and the training of nuclear technology professionals.
Isotopes produced at the reactor have been used in the diagnosis and treatment of over 50,000 patients, primarily in the fields of oncology and cardiology. Additionally, the reactor supplies industrial sectors with isotopes, such as cobalt-60 for radiography. The TRIGA reactor also plays an important role in international collaboration. Researchers from around the world visit the institute to use the reactor for experiments, and the TRIGA reactor is regularly cited in professional circles as an example of how even a small research reactor can make significant contributions to the scientific community. Over the years, it has become a cornerstone for advancing nuclear technology, safety culture, and education in Slovenia. The reactor was originally designed and supplied by the American nuclear company General Atomics, with local companies contributing to its construction.
In 1991, the reactor underwent significant upgrades, which included modifications for pulsed operation. Despite being over 50 years old, the TRIGA reactor has been operating continuously with no significant incidents or equipment failures, adhering strictly to safety standards.
Our visit to the TRIGA reactor provided us with invaluable insights into the ongoing work at JSI. The reactor stands as a testament to the power of scientific innovation, education, and international collaboration, and it continues to be a key player in the development of nuclear technology and the advancement of science in Slovenia and beyond.
