Which part of the closed loop converts heavy water to ordinary water?(1 point) Responses reactor reactor turbine turbine steam generator steam generator heavy water moderator. EXPLAIN WHY

The part of the closed loop that converts heavy water to ordinary water is the heavy water moderator. The heavy water moderator is a part of the nuclear reactor, which slows down fast-moving neutrons and allows them to cause nuclear fission in the fuel rods. During this process, some heavy water molecules are converted into ordinary water molecules due to the radiation and heat generated in the reactor. This conversion is a natural byproduct of the nuclear fission process and helps maintain the stability and efficiency of the reactor.
