It was suggested by User:Christopher Thomas that this article be merged into nuclear reactor. Having looked at both articles I don't think this is nessecery so I have removed the template - this does not meen that the same sugestion can not be made later, or indeed the merge made without discussion.

Carbon is not used in control rods because it is not a neutron absorber. (small cross section for absorbtion). It is used in some reactors as a moderator (graphite moderated reactors, like Chernobyl for instance) because it does not absorb neutrons, but moderates them to allow them to reach the energy level which will let them cause a fission in the Uranium. Moderating is done by neutrons bouncing off of the neucleus of the carbon atom giving up some of their energy in the collision. —Preceding unsigned comment added by 75.68.15.249 ( talk) 14:57, 8 March 2008 (UTC)
The reference for this material is a web forum. It appears to be a reputable post, and the post also provides a citation:
Journal of Nuclear Materials Vol: 281, Issue: 1, September 2, 2000 pp.84-89
but it would still be nice to have a reference that wasn't a forum post. Does anyone have access to this issue of Journal of Nuclear Materials? Mishlai ( talk) 11:28, 25 September 2008 (UTC)
I realize that this is pretty much the Wikipedia article that covers the entire topic of "things we stick into a nuclear reactor to reduce reactivity". That makes it a little difficult to have a conversation with someone about cruciform blades. One would think that it would make most sense to generalize this to cover all types of this. - Theanphibian ( talk • contribs) 22:14, 20 March 2011 (UTC)
Hello fellow Wikipedians,
I have just added archive links to one external link on
Control rod. Please take a moment to review
my edit. If necessary, add {{
cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Co-60 is used as a gamma ray source, not an X-ray source, hence this edit. Andrewa ( talk) 06:53, 23 November 2023 (UTC)
