The reactor is now producing less steam to go to the turbine. There will be less extraction steam and reheater drain steam going to the feedwater heater.(1.0) Therefore less feedwater heating will occur resulting in colder feedwater entering the vessel (.5) which will cause reactor power to increase about 3% from the positive reactivity addition (alpha m).t.5) (2.0)

  +
c. Rod A.(0.5) The relative flux at the center of the core is higher than at the edge of the core (due to leakage out of the core).
  +
  +
Since rod worth is dependant on the relative fiv:: (ratio of local to average flux), rods located near the center of the core usually have higher wort (1.50)
  +
b. Rod B.(0.5) Upon recovery from a scram, fission product poisons cause a severe flux depression in what was the highest power producing regions. of the core. Effectively, this results in a higher relative flux in the regions of low poison concentratio The result of these shifts in flux distribution is increased worth of the peripheral rods and decreased worth of those in the center of the cor (1.50)
