A method is described to reduce wear on the internal surface of a conduit in a closed-loop fluid system that transports corrosive nuclear material within a nuclear reactor. The method involves injecting two fluids into the conduit: a protective void fluid and a second fluid carrying the nuclear material. The nuclear material-containing fluid flows centrally in a laminar pattern, while the void fluid forms a protective layer around it, preventing direct contact with the conduit walls. By carefully controlling the injection and separation of these fluids, the nuclear material remains isolated from the conduit's surface, effectively limiting corrosion. This design prolongs the conduit's lifespan and enhances the system's efficiency by reducing surface degradation.

Interstitial brachytherapy is a cancer treatment in which radioactive material is placed directly in the target tissue of the affected site using an afterloader. The accuracy of this placement is monitored in real time using a urinary catheter that locates the radioactive material according to the radiation levels measured by sensors in the walls of the urinary catheter. A scintillator that is embedded in the walls of the urinary catheter produces light when irradiated by the radioactive material. This light is proportional to the level of radiation at each location. The light produced by each scintillator is carried through optical fibers and then converted to an electrical signal that is proportional to the light and the radiation level at each location. The radioactive material is located according to the plurality of electrical signals. This location can be used as quality control feedback to the afterloader.
