Furthermore, lead times need not at all be long. In a national effort with a solid competence base the plants will be built in about 5 years.
Four years is the minimum time to build one reactor.
We've gone from a statement that in the most direct reading suggests that all reactors desired may be built by a country "with a solid competence base" in about five years, so long as its part of a national effort, to one that makes it clear that four is an absolute bare minimum time to build one reactor.
Whether fifteen years is a long or short time, it is appreciably longer than five years. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
