Reactor Cost Estimation Formula - Chemical plant design .

May 28, 2008 · The reactor volume at Chernobil was about 400,000 m3 and the cost was about 3.2 billion dollars. You only multiply the volume of your reactor by 3.2 billion dollars and divide it to 400,000 m3, there you go, you have the estimated cost of your reactor. Easy enough? The principle might work on other plant assemblies, I'm not sure about the value .
