Hard to reach esp. by greenpeace and other terrorists, and what could
they do anyway?

I thought the US Cole showed terrorists don't all fear boats. And I'm
sure they could hire some Somali pirates to help out.

Can't they then blow up the reactor when the wind is on-shore? Even if
they don't release much nasty stuff they'd get the panic.
