Question
Chapter 14, Problem 1Q
To determine
Explain the functions of moderator and control rod in fission reactor.
Expert Solution & Answer
Answer to Problem 1Q
Moderators slows down the neutrons formed during fission, and control rods absorb the excess neutrons to control the fission rate
Explanation of Solution
In a nuclear reactor moderators are used to control the speed of the neutrons produced as the end product of fission. Moderators will slow the fast moving neutrons. Commonly used moderators are water, solid graphite, heavy water etc.
Control rods are used to control the fission rate of uranium and plutonium. Control rods are made up of elements like carbon, boron, cadmium, silver which are capable of absorbing neutrons, and hence controls the fission rate.

- Part C Find the height yi from which the rock was launched. Express your answer in meters to three significant figures. Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. PROBLEM-SOLVING STRATEGY 4.1 Projectile motion problems MODEL: Is it reasonable to ignore air resistance? If so, use the projectile motion model. VISUALIZE: Establish a coordinate system with the x-axis horizontal and the y-axis vertical. Define symbols and identify what the problem is trying to find. For a launch at angle θ, the initial velocity components are vix=v0cosθ and viy=v0sinθ. SOLVE: The acceleration is known: ax=0 and ay=−g.
