Session Title:
WFS - Small Reactors

Daniel Meneley (AECL/UOIT)


The assembly known as a CANDU power reactor consists of a number of standardized fuel channels or “power modules”. Each of these channels produces about 5 thermal megawatts on average. Within practical limitations on fuel enrichment and ultimately on economics, the number of these channels is variable between about 50 and approximately 700.


Small reactors suffer from inevitable disadvantages in terms of specific cost of design/construction as well as operating cost. Their natural “niche” for application is in remote off-grid locations. At the same time this niche application imposes new and strict requirements for staff complement, power system reliability, and so on. The distinct advantage of small reactors arises if the market requires installation of several units in a coordinated installation program - a feature well suited to power requirements in Canada’s far North.


This paper examines several of the performance requirements and constraints for installation of these plants and presents means for designers to overcome the consequent negative feasibility factors.
