On the Isotope Separation by Counter-current Gas Centrifuge, (II)

Separation of porphyrins by counter-current distribution.

The recent development by Craig (l-3) of an all-glass machine for liquidliquid counter-current fractionation makes possible the application of his method to the separation of porphyrins which cannot readily be separated by the sensitive Willstatter “HCl number” method. In this paper we have studied the application of the Craig method to the separation of a mixture of three known porphyrins, usi...

India’s Gas Centrifuge Enrichment Program:

This report traces the history of India’s centrifuge enrichment program and assesses its current and projected enrichment capacity based on publicly available procurement data and other publicly available information, which were analyzed using specialized software. Our conclusion is that India is currently operating between 2,000 and 3,000 centrifuges at the Rare Materials Project (RMP), India’...

The gas centrifuge and nuclear weapons proliferation

© 2008 American Institute of Physics, S-0031-9228-0809-020-0 The most difficult step in building a nuclear weapon is the production of fissile material. One can either make plutonium-239 in a nuclear reactor or enrich uranium to increase the abundance of its fissile isotope uranium-235. Historically, enrichment has been the more obscure of the two routes, but the recent spread of one technology...
