Yes, there are a number of risks.
First of all, there are the risks associated with small facilities--for example, Slowpoke reactors, etc.—where you would not anticipate that they could possibly create an incident amounting to $650 million just because of the size and the amount of radioactive material that's contained in them. So whereas they would be covered by the $650 million of funds and insurance, the federal government would be reinsuring the majority of that amount. These reactors usually are located in universities, etc., but by far the majority of that risk would be covered by the federal government.
Another area of risk would be risks that the insurers simply are not willing to cover, such as I had indicated previously—latent illnesses associated with release, for example. The insurers are only willing to cover damages for a period of 10 years after the incident, so in order for us to be able to ensure that victims who might be exposed to an incident would have coverage for a period longer, the 30 years that we're proposing, it would be necessary for the federal government to carry that risk.
For example, another area would be in the area of terrorism. In the event of a terrorist incident that would cause damage, the insurers have indicated that they would not be willing to cover the entire amount, and so it would be necessary for the federal government to provide.
I think those are the two main categories: the supplementary insurance associated with small facilities and the substantive risks that the insurers are unwilling to cover.
