Calculating Reactivity

Reactivity is often expresed in units called; dollars neutron multication factor, pcm mpm mpother the razeo neutronia oe genero factor, k, which intrafo tho neutroni reactive for a reactive for a reaciutroon.

1f 1f; FLT: 0 123; Abo3; Abo3; Asuno = (k-1) / k 1; FLT: 1 123; 1f 3;

Whn k equals 1, the reactor is critkal, and reactivity ios zero. Values greater than 1 institute supercriteriaty, while values less then 1 increate subcriteriþi. Accurate of reactivity involvite neutron flux ling rod position.
