Construction Permit Application (CPA) Submitted to U.S. NRC
Nano's KRONOS MMR CPA was formally submitted to the U.S. NRC (by the University of Illinois), making Nano one of only a handful of Gen‑4 developers at this stage and the first commercially ready microreactor to submit a CPA. The company expects a ~12‑month NRC review period following acceptance and targets initial construction activities in mid‑ to late‑2027, validating design maturity and advancing the program from engineering to potential construction.
