Question
Chapter 20, Problem 20.43QP
Interpretation Introduction
Interpretation: The function of a moderator and a control rod in a nuclear reactor should be explained.
Concept introduction:
- Moderator are used to slow down the speed of neutron .this is the main function of the moderator.
These material are capable to decrease the speed of neutron produce as fissionable
- For example: Helium at 1000atm and 1273K.berilium at high temperature, sodium at 773to 873 K used in breeder reactor.
- Control rods: As the name shows that this material designed to control the fission reaction.
It is made up of some neutron absorbing material like cadmium, helium or boron.
To determine: the function of moderator and a control rod in a nuclear reactor explained.

Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
