👉 Spent fluid, often referred to as reclaimed or used fluid in nuclear reactors, is the liquid that remains after the primary coolant has passed through the reactor core and transferred heat to a secondary coolant system. This fluid is typically contaminated with radioactive isotopes, impurities, and heat, making it unsuitable for direct use in the reactor. The spent fluid undergoes a series of purification processes to remove these contaminants and reduce its radioactivity, making it safer for handling and disposal. These processes can include filtration, chemical treatment, and sometimes even precipitation or distillation, ultimately transforming the spent fluid into a form that can be safely stored or, in some cases, reused in other applications.
