(note: the pressurized heavy water reactor (PHWR) (heavy water being deuterium oxide, D 2 O, which is about 10% more dense than normal (light) water), such as the indian-designed heavy water reactor (HWR) based in principle on CANDU (Canada deuterium-uranium reactor), the BWR and the Russian-designed WWER/VVER (PWR-type) are described in Chapters 21, 20 and 19, respectively). 0000066812 00000 n 0000069705 00000 n 0000068889 00000 n 582; 238. CANDU reactors produce electricity through a process known as fission. These reactors are heavy water cooled and moderated pressurized water reactors. All CANDU reactors use heavy water as the moderator, in a system that is completely separate from the reactor coolant heavy water. The graph is for gross electrical production (including a small amount of electrical equivalent of process steam for Bruce-3 and 4 and RAPS-1 and 2). • In fact, CCANDU ANDU is extremely fflexible lexible - can burn enriched enriched uranium, mixed-oxide (U/Pu) fuels, or even irradiated fuel from light-water reactors. x��Ykp���+�? 2017.03.08 - Recreated all pdf files to fix minor equation font issues arising on Apple Mac OS and iOS systems. �2�;�ؔ�L�lԐ*�E�ч"9c�{���8����j�F���Kc�Ȳ��rg��9�Q��%�ٔs�n8�'7�l�9�IJ)�E�>25�S��2�����+�ć�������X�Ԃ��3��_�� ٷ����6̼��_�>k�=��ёx�/�F�eEvE4�'�`�b׵����Q����$�0�=�LLE�י2���I��� English: Schematic diagram of the pressurised heavy water cooled version of a CANDU (CANada Deuterium-Uranium) nuclear reactor. Furthermore, it is important to note that the existing CANDU reactors can be converted to use thorium-based fuel with small changes to the design, and the majority of the reactor systems would not need any modification.
