In this way
The Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) concept is a new class of bimodal nuclear propulsion system that uses a "wave rotor topping cycle," as per a NASA blog post. The scientist behind the proposal, Prof. Ryan Gosse from the University of Florida, believes it could reduce travel time to Mars to a mere 45 days.
Your OP describes RDRE engines. They are not nuclear as
The rotating detonations are continuous, Mach5 explosions that rotate around inside the rocket engine, and the explosions are sustained by feeding hydrogen and oxygen propellant into the system at just the right amounts...
NTP/NEP engines are totally different as NTP is a nuclear reactor thermally heating propellant. NEP is ion thrust (not nuclear)
Apologies.
Yup too many revolutionary engines these days :)
