Chat Onlinefactor. If the leakage is small enough to be neglected, the multiplication factor depends only upon the balance between production and absorption and is called the infinite multiplication factor, k∞ (an infinitely large core can have no leakage). When the leakage is included, the factor is called the effective multiplication factor (keff ...
