I need books and articles on liquid sodium reactors.
Go to Databases by Subject. There are many good databases to try. We should use the EBSCO databases under the Business & Industry, Science, and also Technology tabs.
I tried several searches. You will want to try a few and see what is best for you. "Liquid Sodium" "Sodium Cooled Reactors"
"Liquid Cooled Nuclear Reactors" were all good search phrases. Limit by full text, publication date, and subject on the left.
For books, we did not have much. Go to the WorldCat link below and search chemical reactor.
