Can someone explain to me the basic process involved in an approach to critical with a nuclear reactor. I understand that you basically start with the rods all the way in and bring them out, while taking counts - waiting for them to stabilize. I understand with the penultimate method, you change the control rod position and take count rates, and then take the ratio of the count rates and extrapolate to the x-axis with each measurement in order to determine the critical point, however I'm confused as to how the 1/M method works to find the critical position.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks,

Derek
