Neutron flux is typically measured using neutron detectors such as ionization chambers or fission chambers. These detectors count the number of neutrons passing through a specific area over a period of time.
Neutron flux is directly proportional to fission product rate. This means that as neutron flux increases, so does the rate of fission product production.
Fission product yield is determined experimentally by measuring the amount of individual fission products produced during a nuclear reaction. These measurements are then used to calculate the overall yield.
The formula for calculating fission product rate is: FPR = φ * Y, where FPR is the fission product rate, φ is the neutron flux, and Y is the fission product yield.
The accuracy of the calculations for fission product rate depends on the accuracy of the measurements for neutron flux and fission product yield. With precise and reliable measurements, the calculations can be highly accurate.
