Additional Information and References:
IN 1971 a SLOWPOKE 1 research reactor, designed and commissioned at Atomic Energy of Canada Limited (AECL) in Chalk RIver, Ontario, was installed at the University of Toronto. In 1976, this was replaced by a commercial SLOWPOKE II reactor. The SLOWPOKE laboratory operated at the Department of Chemical Engineering until the reactor was decommissioned in 1998. It focused on neutron activation analysis.
