MARIA research reactor
The MARIA reactor is currently the only and unique research facility of this type in Poland and in the world, having a significant importance for public health, as a producer of radiopharmaceuticals, economy and science. It is a water and beryllium moderated high flux pool-type reactor with graphite reflector and pressurised channels containing concentric six-tube assemblies of fuel elements. Medical radioisotopes generated by the plant are a vital component in a range of medical research projects. Approximately 380.000 nuclear medicine procedures are conducted annually in Poland, highlighting the importance of the reactor’s continued operation and its role in public health and medicine. About 17 million people worldwide use products based on radioisotopes produced in the reactor, with MARIA covering about 10% of the global supply of molybdenum-99.
In 2024, the MARIA research reactor celebrated its 50th anniversary.
