Researchers use one-of-a-kind expertise and capabilities to test fuels of tomorrow
At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

The N Reactor is equipped with 12 horizontal U-tube steam generators. Originally, these contained Type 304 stainless-steel tubes. From 1964 through 1971, ten were retubed with Inconel-600 tubes because severe stress corrosion cracking was experienced in stainless-steel tubes. Tube performance is monitored by eddy-current examinations, tube removals for destructive examination, and checking for radioactivity in the secondary system. The results of this program show that no significant corrosion has occurred in the Inconel-600 tubes in 11 yr of service. Five tube leaks have occurred in the two remaining units with Type 304 stainless-steel tubes over the same period.
