Power Systems The power level of nuclear reactor can be increase by ( K = multiplication factor ) raising the value of K above 1 and keeping it at raised value. raising the value of K above 1, but later bringing it back to K = 1. lowering the value of K below 1 but later bringing it back to K = 1. lowering the value of K below and keeping at that lowered value. raising the value of K above 1 and keeping it at raised value. raising the value of K above 1, but later bringing it back to K = 1. lowering the value of K below 1 but later bringing it back to K = 1. lowering the value of K below and keeping at that lowered value.
