What are the byproducts produced and extracted from the RBMK-1000 reactor and the CANDU reactor?

The RBMK-1000 reactor primarily produces plutonium-239 as a byproduct of its uranium fuel, along with various isotopes of cesium, strontium, and iodine due to fission processes. In contrast, the CANDU reactor, which uses heavy water as both a moderator and coolant, generates tritium as a significant byproduct, along with isotopes like cesium-137 and strontium-90 from fission. Both reactors contribute to the production of radioactive waste, which requires careful management and disposal.
