ENGINEERING EVALUATION STUDIES, HEAVY WATER MODERATED POWER REACTOR PLANTS. Quarterly Progress Report, October-December 1960
Studies of the corrosion of steels by water were reviewed. Additional tests were carried out tc supplement existing data. An investigation of corrosion product deposition was initiated to study the deleterious effects of heat transfer and fluid flow in the primary system components. Preliminary analysis of major mechanical equipment specifications for use with heavy water plants indicated that they are not significantly different from those for hight water nuclear plants. The testing program designed to quantitatively evaluate the leakage losses of heavy water from mechanical components is being continued. Test results for shaft seals indicated excellent results when the seals were operated at rated conditions. Excessive leakages occurred, however, when the seals were operated at low pressures. A program is being conducted tc correlate the designs of various heavy water moderated reactor plants in the United States, Canada, and Europe. As a result of analyses and evaluations, it is expected that cost reductions for both the full-scale and prototype, boiling D/sub 2/0, pressure tube, direct cycle plants will become apparent. Data from various test were combined in an analysis to estimate the consequences of a failure of a pressure tube in the boiling D/sub 2/0 prototype. It was concluded that a pressure tube failure with an opening of less than 3 in.2 would not seriously damage its calandria tube. Computer programs were developed for studies underway to prepare an optimum design of each of several D2/sub 2/ moderated power reactor plant concepts with a net capacity of approximately 300 MW(e).
