A nuclear reactor have two types of events:
High-energy particle touch nuclear, released three high-energy particles and a low-energy particles;
Low-energy particle touch nuclear,released two high-energy particles and a low-energy particles;
Know that the first time(0 microsecond),there is only one high-energy particle in the nuclear reactor.Every touch cause a microsecond. So, how many particles in the nuclear reactor after n microseconds?
Every particle is still alive after touching.
