Why nuclear debate in Canada has intensified - and why it will continue

Some activities of members of the Canadian antinuclear movement (notably Energy Probe and the Canadian Coalition for Nuclear Responsibility) are discussed. Some topics of controversy discussed include positive versus negative void coefficients, shutdown systems, and allegations that documents dealing with safety were secret. Both Pickering and Bruce have cadmium rods for the primary shutdown system, but Pickering has moderator dump for the secondary system, whereas Bruce has poison injection into the moderator. A brief description is included. The AECB could codify and publish some of its rules for licensing, but it must consider each case on its merits. The opponents seek an absolute theoretical safety which would exceed all practicality. (N.D.H.)
