US Commercial Light Water Reactors

This is a good article about Heavy Water. It is used ,for instance in the Canadian CANDU reactors that are not enriched, i.e. the fuel is natural uranium.
There’s one sentence that I believe needs to be changed , i.e. that " enriched reactors do not have a moderator" All US commercial reactors use enriched (up to 5 percent by weight in U-235). Fissioning occurs primarily with neutrons that have been “thermalized” or slowed down in speed by standard but pure, de-ionized water used as a moderator AND coolant. That’s why the term Light Water Reactors is used to described the US commercial reactors.
