Since the graphite reduce the speed of an electron (13,200 km/s) to the speed of (22,000 m/s).

But some times ordinary water is also used for enriched uranium reactor.

What is moderator?

Chanti said:   1 decade ago
I think graphite used but may be any substance used to slower down the rate of reaction.

Heavy water and graphite are main constituent of nuclear reactor.

JBP said:   1 decade ago
Moderator means speed slower

Anju kumari said:   1 decade ago
I think radium is used because it moderate the rate of reaction.

Kriti said:   1 decade ago
Graphite is used as moderator in nuclear reactor because it slow downs the fast moving electrons which are coming from fission reaction.

Ram Dular Sahu said:   1 decade ago
Graphite is used as which speed reduced of reactor.

Pradeep said:   1 decade ago
Since graphite absorb neutron. Which helps to produce nuclear reaction in a controlled manner.
