A spherical reactor composed of 235U metal is operating in a critical steady state. Discuss what probably happens to the multiplication of the reactor and why, if the system is modified in the following ways: 1. The reactor is rapidly compressed to one-half its original volume 2. A large, fat reactor operator accidentally sits on the reactor, squashing it into an ellipsoidal shape 3. A thick sheet of cadmium is wrapped around the outside of the reactor 4. The reactor is suddenly immersed in a large container of water 5. A source of neutrons in placed near the reactor 6. Another identical reactor is placed a short distance away from the original reactor 7. One simply leaves the reactor alone for a period of time
