I of borated water. The boron concentration of this water is sufficient to maintain the reactor subcritical approximately by 5%Ak/k in the cold condition with all rods inserted.(2) Periodic checks of refueling water boron concentration insure that proper shutdown margin is maintained.
Part A6 allows the control room operator to inform the manipulator operator of any l
impending unsafe condition detected from the main control board indicators during fuel movement.
3 During the refueling operation a substantial number of station personnel and perhaps some regulatory people will be in the containment. The require-ments are to prevent an unsafe amount of radioactivity from escaping to the 7
environment in the case of a refueling accident, and also to allow safe avenues of escape for the personnel inside the containment as required by the l
Wisconsin Department of Industry, Labor and Human Relations. To provide for these requirements, the personnel locks (both doors) are open for the normal refueling operations with a third temporary door which opens outward installed across the outside end of the personnel lock. This hollow metal third door is equipped with weather stripping and an automatic door closer to minimize the exchange of inside air with the outside atmosphere under the very small differential pressures expected while in the refueling condition. Upon sounding of the containment evacuation alarm, all personnel will exit through the temporary door (s), and then all personnel lock doors shall be closed. As soon as possible, the fuel transfer gate valve shall be closed to back up the 30 foot water seal to prevent escape of fission products.
