Editing Thorium Reactor Suppression Controversy (section)

== Milton Shaw and the AEC ==

Milton Shaw's role is the most controversial element of the documented history. Shaw was:

* A protégé of Admiral Hyman Rickover (developer of naval nuclear propulsion, which used pressurised water reactors).
* Deeply ideologically committed to the LMFBR programme.
* Known for a confrontational management style that alienated many at ORNL.
* The primary bureaucratic force that defunded the MSRE and pressured Weinberg.

Weinberg wrote that Shaw represented "the victory of the plutonium fast breeder" within the AEC. Critics of the suppression narrative note that Shaw's preference for the LMFBR was based on genuine technical arguments about breeding ratios, not merely weapons considerations. Defenders of the conspiracy view note that the LMFBR was itself cancelled after enormous spending, while a superior and safer alternative — the MSR — was abandoned without ever receiving a fair comparative evaluation.
