King stared at the dumping switch, mounted behind glass at the top of the instrument board. "There's fuel enough," he said softly, as if he were alone and speaking only to himself; "there's been fuel enough for weeks."
He walked swiftly over to the switch, smashed the glass with his fist, and pulled it.
The room rumbled and shivered as two and a half tons of molten, massive metal, heavier than gold, coursed down channels, struck against baffles, split into a dozen streams, and plunged to rest in leaden receivers — to rest, safe and harmless, until it could be reassembled far out in space.
AFTERWORD
December 1979, exactly 40 years after I researched BLOWUPS HAPPEN (Dec. '39): I had some doubt about republishing this because of the current ignorant fear of fission power, recently enhanced by the harmless flap at Three Mile Island. When I wrote this, there was not a full gram of purified U-235 on this planet, and no one knew its hazards in detail, most especially the mass and geometry and speed of assembly necessary to make "blowups happen." But we now know from long experience and endless tests that the "tons" used in this story could never be assembled — no explosion, melt-down possible, melt-down being the worst that can happen at a power plant; to cause U-235 to explode is very difficult and requires very different design. Yes, radiation is hazardous BUT—
RADIATION EXPOSURE
Half a mile from Three-Mile plant
during the flap 83 millirems
At the power plant 1,100 millirems
During heart catheterization for angiogram 45,000 millirems
