Quick Fact:
At full capacity, workers had to load over 60,000 fuel elements into the reactor’s 2,004 process tubes. After an average of 100 days in the reactor, a fuel element would be sufficiently irradiated to be removed. The fuel elements were ejected from the rear face of the reactor where they fell into a 20-foot pool of water. Here they cooled off for about 90 days until they were ready to be shipped to the chemical separations plant in the 200 area.
