Multipurpose Applied Physics Lattice Experiment

MAPLE, short for the Multipurpose Applied Physics Lattice Experiment, later renamed MDS Medical Isotope Reactors (MMIR), was a dedicated isotope-production facility built by AECL and MDS Nordion. It included two identical reactors, I and II, as well as the isotope-processing facilities necessary to produce a large portion of the world's medical isotopes, especially molybdenum-99, medical cobalt-60, xenon-133, iodine-131 and iodine-125.
