Yes, you can run it for quite some mileage. You know, the safety systems were upgraded in 2005 to meet modern standards.
My understanding is that this morning CNSC and AECL were discussing what might be done to extend the life of the NRU reactor. My understanding is that the CNSC would follow the same route it follows in extending the lives of power reactors.
As you're probably aware, reactors around the world are having their lives extended from the current phase of 40 years up to 60 years. There is a formal process, which is followed around the world by many regulators, for doing that.
In essence, you step back and do what is called an integrated safety review. The CNSC has documents out that tell licensees how this needs to be done. The licensee has to basically do a detailed assessment of the status of that reactor, how it meets modern standards, and what would be needed to extend its life for, in the case of power reactors, 20 years. I would imagine that the same process can be followed for the NRU.
