ERRORS in rebuttal to "Pandora's Promise"

[kristopher]

46. Sorry... once again, you've corrected someone when it's you that's wrong

Robert W. Selden in his presentation "Reactor Plutonium and Nuclear Explosives" that said Pu240 is fissile.

• All plutonium isotopes can be used directly in nuclear explosives.
• The concept of “denatured” plutonium (Pu which is not suitable for nuclear explosives) is fallacious.
• A high content of the Pu-240 isotope is a complication, but not a preventative.

...

Nuclear Reactivity (cont’d)
• All Pu isotopes are fissile for fast neutrons.

Selden in a 2009 presentation

Robert W. Selden, a former leader of the applied theoretical physics division at Los Alamos National Laboratory, also urged the use of international safeguards to avoid weapons proliferation. He said that all plutonium isotopes, including those in spent fuel, can be used directly in nuclear explosives. He dismissed as fallacious the concept that plutonium from spent fuel could somehow be "denatured" so it cannot be used in a weapon.

Kemp and Selden spoke at a 12 May (2009) Hill luncheon briefing on nuclear proliferation co-sponsored by the AAAS Center for Science, Technology and Security Policy and the Nonproliferation Policy Education Center.

Everyone should read the article at the above American Association for the Advancement of Science link because frankly, it shows what we all already know, GregPam's claims are an exercise in shoveling more manure than Hercules in the Augean Stables.
If you have any type of plutonium in sufficient quantities, Selden said, "you can make a bomb."
-R.W. Selden

Now if GregPam wants to refute this with claims that Selden isn't qualified or is dated in spite of the AAAS recognition of him as an expert in the field, then we'd need to see confirmable information that provides verification of credentials more impressive than Selden's.
