Illustrates the remote repair and modification of the HRE-2 core vessel, following the formation of two holes which permitted transfer of fuel to the blanket side of the reactor. Shows how special equipment had to be designed for repairing the HRE-2, and the problems involved in working with the reactor where the radiation level in the vessel was greater than 100,000 Roentgen per hour.
