OSIRIS -- a radiopurity detector for JUNO — •Christian Wysotzki for the JUNO collaboration — RWTH Aachen University - Physics Institute III B, Aachen, Germany

The Jiangmen Underground Neutrino Laboratory (JUNO) is a 20 kt liquid scintillator based neutrino observatory, which is currently under construction in southern China.

OSIRIS (Online Scintillator Internal Radioactivity Investigation System), as one of JUNOs subsystems, monitors the radiopurity of the liquid scintillator. Stringent limits regarding the contamination of radioactive isotopes, especially uranium and thorium have been defined to ensure the success of JUNOs physics program.

The assembly and commissioning of OSIRIS is foreseen for 2022. This talk will give an overview of the design philosophy, the detector systems, and the current status.
