The Micro Modular Reactor (MMR
In mid-2019, the Canadian government started the environmental assessment for this small modular reactor project proposed by Global First Power (GFP) with support from Ultra Safe Nuclear Corporation (USNC) and Ontario Power Generation (OPG). The Micro Modular Reactor is a 15 MW thermal, 5 MW electrical high-temperature gas reactor, drawing on operational experience from pebble bed reactors developed by China, Germany, Japan and the USA.
In mid-2020, a joint venture was formed between Ultra Safe Nuclear Corporation (USNC) and Ontario Power Generation (OPG) to build, own and operate the proposed Micro Modular Reactor (MMR) project at the Chalk River Laboratories site. The joint venture – the Global First Power Limited Partnership – is owned equally by OPG and USNC-Power, the Canadian subsidiary of USNC.
Safer Reactor Core
The buried reactor core consists of hexagonal graphite blocks containing stacks of Ultra Safe’s FCM
Modules will be sized for standard International Standards Organization shipping containers; this means they can be transported easily by ship, rail or road. This includes ice roads.
Helium gas is the MMR
The plant has no need for active systems to remove heat. Additionally, the plant does not need any outside services, including electrical power, to operate safely.
The fuel safety margin is so large that fission product retention is accomplished entirely by the fuel; no other containment is needed. There are no sudden temperature rises – the reactor shuts down naturally in all accident conditions.
- Passively cools in all scenarios
- No active safety systems needed
- No water or power needed
Site Area would only be 5 acres and the reactor could be installed in a few months.
