Assembling Nuclear Power Source
The sequence of photos at left and below shows the moving of one of the 368 fuel bundles from a storage cavity into the fuel chamber in the reactor. The bundle which contains 49 rods filled with nuclear pellets has just been lifted out of the storage case at the top. The man shown wiped it clean as it moved upward. The second picture shows it being moved through giant doors between the two chambers and the device which moves it. The device moves on tracks over the two chambers. Three men help get the bundle in its proper hole in the fuel chamber. The one in the center operates the lifting device. One on each side, with the use of binoculars, makes sure the bundle is properly lined up with the hole. The lower picture shows it being lowered into place. Each bundle must go into a specified location. When loading is completed later this week each of the squares will hold a fuel bundle. Although it's not obvious in the lower picture, there is water on top of the fuel bundles. When loading is completed this cavity will be filled with water. When in operation the steam generated by the water boiled by nuclear reaction will be sent into a turbine, producing electricity.

THE THREE round devices shown in the top picture and the two devices shown in the photo at right all go into the reactor on top of the fuel. The steam separator, shown in the foreground in the lower photo, will go in first, with the steam dryer, also in the lower photo, on top of it. On top of the dryer will go the round device shown at right in the upper photo, followed by the middle sphere with the rounded one on top of the 110-foot containment ves-
sel. The steam that will go into the turbine is described as dry.
THIS is another view of the fuel storage area and shows in the corner the radioactive device which will be put into the reactor to trigger the first chain reaction. The device is currently packed in a 10-ton leaded cask. Exposed to radioactivity in a California test reactor, it will provide the background neutron counts to start the reactor safely.

IE CHAIRMAN and President Duane Arnold gestures as he talks about the nuclear power plant named after him. He wears the type of outfit everybody must woar in the reactor area while fuel is being loaded. The coveralls are yellow. The outfit is just one of the precautions taken to make sure that nothing falls into the fuel chamber while fuel is being loaded.
