What killed the Maples reactors?

The article tackles the issues surrounding the Maples project. The perceived failure of Maple 1 and Maple 2 as reactors is blamed to Canada's nuclear regulator and sometimes to the Canadian government since it canceled the project before crucial technical questions had been resolved. The problem related to the calculation of the power coefficient of reactivity (PCR) being resolved by the Atomic Energy of Canada Limited (AECL) is discussed. Also mentioned is the shortage of medical isotopes worldwide.
