what is the role of control rods in a fission reaction
You might need to use the wave to help control the applications. This will help you to know when to make more products.
When the reactor fuel has been used for some time the fission products formed build up and do produce a significant amount of heat from their radioactivity, several percent of the total reactor output. When the reactor is shutdown, be it deliberately or as a result of some sort of incident, often due to an outgoing grid line fault, this heat is still there although the fission power has dropped to zero. To keep the reactor cooled some back up cooling is required and for safety this needs to be powered by back up diesels in case the grid connection has been lost.Apart from that, the highly radioactive reactor core needs to be well shielded to allow the operating staff access for maintenance and repair, refuelling, etc.

what is the role of control rods in a fission reaction
A typical uranium fission event produces 2 to 3 neutrons. These neutrons are moderated (slowed down) and go on to initiate the fission of more uranium. On average, in a controlled reaction that is maintained at normal criticality (KEffective = 1), each fission creates exactly one neutron that is used to produce another fission.
In nuclear fission an atom is broken up into two or more new particles. Sometimes this happens all by itself, but when we want it to happen more rapidly we use a critical assembly of fissile fuel and a moderator, which multiplies the neutron flux. The moderator slows down the neutrons produced in each fission which can then cause further fissions, resulting in a chain reaction. Each fission also releases energy as heat. The chain reaction is controlled at a steady level by control rods which absorb neutrons.
Please mention the reaction.

The phenomenon which best explains the role of catalyst in a reaction is that the catalyst lowers the Energy of Activation :)
catalyse the reaction.
It catalyses the biochemical process thus it increases the rate of reaction
See for the biological role at: http://en.wikipedia.org/wiki/Manganese.
The moderator in a nuclear reactor slows (moderates) the neutrons that are released during fission, so that they can subsequently cause fission in other atoms. When the neutrons are initially released, they tend to have too much energy, which impacts their ability to cause subsequent fission.
