A secret nuclear weapons program is a ghost in the machine, detectable only when the system of information control momentarily lapses or breaks down. A close look must be taken at the gap between the official account and unexpected events.
TEPCO, Japan’s nuclear power operator, initially reported three reactors were operating at the time of the March 11 Tohoku earthquake and tsunami. Then a hydrogen explosion ripped Unit 3, run on plutonium-uranium mixed oxide (or MOX). Unit 6 immediately disappeared from the list of operational reactors, as highly lethal particles of plutonium billowed out of Unit 3. Plutonium is the stuff of smaller, more easily delivered warheads.
A fire ignited inside the damaged housing of the Unit 4 reactor, reportedly due to overheating of spent uranium fuel rods in a dry cooling pool. But the size of the fire indicates that this reactor was running hot for some purpose other than electricity generation. Its omission from the list of electricity-generating operations raises the question of whether Unit 4 was being used to enrich uranium, the first step of the process leading to extraction of weapons-grade fissionable material.
The bloom of irradiated seawater across the Pacific comprises another piece of the puzzle, because its underground source is untraceable (or, perhaps, unmentionable). The flooded labyrinth of pipes, where the bodies of two missing nuclear workers—never before disclosed to the press— were found, could well contain the answer to the mystery: a lab that none dare name.
