Sonya Thadikaran. Nuclear Reactions. Curriculum Expectations. Describe the scientific principles of fission and a chain reaction and their applications in nuclear generating stations (e.g., the scientific principles applied in the CANDU reactor);
Once this is done, they are asked to exchange the information sheets with their peers and each person reads one line from their friends sheet and a discussion ensues.
(To my peers, play this game, it’s really fun!!)
An individual report is submitted to the teacher of today’s class room understanding.
Nuclear fusion is the process by which two or more atomic nuclei join together, or "fuse", to form a single heavier nucleus. This is usually accompanied by the release or absorption of large quantities of energy.
Fusion is the process that powers active stars, the H-bomb and experimental devices examining fusion power for electrical generation.
Creating the required conditions for fusion on Earth are very difficult….
A series of chemical reactions in which one product of a reacting set is a reactant in the following set.
The main steps of a chain reaction are:
The CANDU, short for Canadian Deuterium-Uranium reactor is a Canadian-invented, pressurized heavy water reactor. The acronym refers to its deuterium-oxide (heavy water) moderator and its use of (originally, natural) uranium fuel.
The CANDU reactor functions in a manner similar to a pressurized water reactor (PWR). Pressurized coolant is passed through the fuel bundles to cool them. This hot, pressurized cooling water is carried to a steam generator where the heat energy is transferred to light water and converts it into steam. This steam is then used to turn the steam turbines which turn the generator, creating electricity.
