Thank you for your question.
I think your comment contains a few sub-questions. I would like to answer by making several points.
There certainly is a risk of accidents happening in the nuclear sector. The risks are there and it's always a possibility. However, we think the probability is very low. At the same time, we need a compensation system and legislation to protect citizens as well as every aspect of our economic activity, the environment and public health.
In developing Bill C-22, we have had many discussions with various stakeholders and with the population. We have imagined scenarios that could lead to an accident in Canada, taking into account our nuclear reactor's model, system and context.
With your permission, I will carry on in English.
We modelled the context—and certainly it was done a number of years ago—such that the design of the reactor and the situation provide for an incident contained within the design parameters and within the structures of the reactor. Procedures are built into the engineering to provide for things to shut down or to happen, and there are backup procedures and backups to backups that limit the potential for an incident to escalate into a more substantial incident.
The modelling looked at a scenario in which an incident would be contained within a nuclear facility. It also looked at a number of different contexts, one in
Gentilly, in Quebec, and another one here in Ontario, where there are reactors. In such cases, I believe the scenario would amount to $100 million, which includes costs and expenditures from an accident that would take place in the context of developing or installing a reactor.
In that context, it was believed to be in the order of about $100 million. The modelling did not model the scenario of a Fukushima or a Chernobyl, being that these are a very, very low probability and, if you will, very unique circumstances. In each of those, it hasn't been something that we've looked at in terms of trying to design a system to protect against those types of incidents.
In the case of Fukushima, I believe the cost of the Fukushima accident is in the order of $30 billion at this point and is expected to be much more as it goes on. It's a running total, if you will. In the Chernobyl case, I'm not sure of the figures for that one. It is not one in which the countries involved have been as transparent about the cost structures.
I think you had a third reference. Three Mile Island? For Three Mile Island in the United States, I'll have to get back to you on the exact numbers of that particular incident, although it's not considered a severe incident, if I could use language of that sort. There was one in the United Kingdom in the 1950s that was a bit more substantial in terms of an incident in which there was a release of radiation.
For the three examples that you have posed, certainly we can get back to you with the numbers, if you wish. On the design scenarios around the Canadian context, our colleagues at the Canadian Nuclear Safety Commission would have done and have done some modelling work also, and some work in terms of incidents, and may be able to provide further evidence and further information to you in response to your question.
