by Stephen F. Ashley
What stops rogue states or terrorists from acquiring the materials for a nuclear bomb? Stephen explores the different barriers, from material to technological, and describes the categorisation of these barriers from a scientific perspective. He discusses the resistance of technologies to proliferation, raising the issue that such definitions are unknown in novel fuel technologies of the future. Anyone who has ever been kept awake at night wondering whether Plutonium or Uranium is easier to weaponise should read this piece.
