A brief review has been made of the status of technology in control system design for heavy water reactors. This review was made for the Heavy Water Program Office to assist in determining research and development requirements for control systems of large heavy water power reactors. This report includes: 1. A review of control mechanisms for heavy water reactors, and 2. A review of control systems used in current heavy water reactors.

Heavy water (deuterium oxide) played a sinister role in the race for nuclear energy during the World War II. It was a key factor in Germany's bid to harness atomic energy primarily as a source of electric power; its acute shortage was a factor in Japan's decision not to pursue seriously nuclear weaponry; its very existence was a nagging thorn in the side of the Allied powers. Books and films have dwelt on the Allies' efforts to deny the Germans heavy water by military means; however, a history of heavy water has yet to be written. Filling this gap, Heavy Water and the Wartime Race for Nuclear Energy concentrates on the circumstances whereby Norway became the preeminent producer of heavy water and on the scientific role the rare isotope of hydrogen played in the wartime efforts by the Axis and Allied powers alike. Instead of a purely technical treatise on heavy water, the book describes the social history of the subject. The book covers the discovery and early uses of deuterium before World War II and its large-scale production by Norsk Hydro in Norway, especially under German control. It also discusses the French-German race for the Norwegian heavy-water stocks in 1940 and heavy water's importance for the subsequent German uranium project, including the Allied sabotage and bombing of the Norwegian plants, as well as its lesser role in Allied projects, especially in the United States and Canada. The book concludes with an overall assessment of the importance and the perceived importance of heavy water for the German program, which alone staked everything on heavy water in its quest for a nuclear chain reaction.

India's three-stage nuclear power programme involves self sustaining Thorium closed fuel cycle based reactors. It has initiated design and development of the Advanced Heavy Water Reactor (AHWR). AHWR is a 920 MW (thermal) capac- ity, heavy water moderated, boiling light water cooled in natural circulation, vertical pressure tube type nuclear reactor. It is fueled by (Th-233U)O2 pins and (Th-Pu)O2 pins and the reactivity is mainly controlled by neutron absorber rods. Some advantages of Thorium-based fuel cycle are abundance of Thorium in In- dia, closed fuel cycle, reduction of radio toxicity of waste to a lower extent, proliferation resistance (prevent or discourage the production of weapon grade material). AHWR offers clean, sustainable nuclear energy, and is one of the flagship technologies of India's nuclear programme. The physical dimensions of AHWR are very large in comparison to neutron migration length, making it susceptible to Xenon induced oscillations and flux- tilting. These undesirable oscillations are common with large nuclear reactors which, if not controlled, can pose unequal spatial distribution of power and increase the chances of fuel failure. Thus it is necessary to devise a control strategy to regulate these spatial oscillations.

Originally published in 1961. This book gives the layman a better understanding of the nature of nuclear power and explains some of the major problems which have to be overcome in making practical use of it. It is concerned mainly with the different kinds of nuclear reactors - their underlying principles are explained and illustrated by reference to particular plants or design studies. Interested readers will find that the discussion of principles is full enough, and the range covered wide enough, to provide a broad view of the subject and a useful introduction to some more technical literature.
