Heavy Water Moderated Reactor Design Studies State-of-the-art Survey

Book excerpt: As part of the Heavy Water Reactor Program Office effort to define the "state-of-the-art" in heavy water moderated reactors a survey of reactor designs and design studies was undertaken. This survey includes: 1. A list and descriptions of the heavy water moderated power reactors either operating or under construction; 2. A list and description of the more recent design studies done no heavy water moderated reactors, with the exception of reactors using organic coolant; 3. A discussion of the various reactor types, as determined by type of coolant, indicating development trends; 4. A discussion of various design features or characteristics that many heavy water reactors have in common, such as pressure tubes, on-line refueling, and D2O loss rates.
