Carbon dioxide production

A method for producing carbon dioxide from limestone comprising the steps of:

• a) generating heat using a nuclear reactor;
• b) transferring heat from the nuclear reactor to the interior of a rotary kiln having an inlet for the introduction of limestone thereto and an outlet for the release of carbon dioxide therefrom, by circulating a heat transfer fluid through feed and return primary conduits through the nuclear reactor and transferring heat from the heated transfer fluid to the interior of the rotary kiln;
• c) introducing limestone into the rotary kiln through the inlet thereof;
• d) operating the rotary kiln to rotate and tumble limestone therein;
• and
• e) collecting carbon dioxide released from the outlet of the rotary kiln;
• wherein the heat transferred to the interior of the rotary kiln and rotation thereof causes calcination of the limestone therein to produce carbon dioxide.
