"Atomic Energy of Canada (AECL) has announced that it will discontinue development of two Maple medical-isotope-dedicated reactors at Chalk River Laboratories in Ontario, effective immediately. Chalk River supplies more than two-thirds of the world's radioisotopes for Canadian healthcare company MDS and its radioisotope developer MDS Nordion of Kanata, Ontario, which is responsible for about 50% of the world supply.

The decision is based on an assessment of the costs of further development of the reactors, as well as the time and risks involved with continuing the project, according to a statement by AECL."

Another bad move by government?

Insufficient information.

There seems to be a long history of problems with the MAPLE reactors. They were supposed to begin commercial isotope production 8 years ago... but they never got there.
It seems that either of them would have been capable of filling 100% of the world's medical isotope market, if they worked as designed.

Calling off a project that's way over budget and behind schedule is never easy, but it is often the right decision to make.
