Fuel removal equipment for TMI-2 [Three Mile Island Unit 2]

The defueling of the original core region of the Three Mile Island Unit 2 reactor was completed in December 1987. A variety of tools and techniques were applied to the task of removing this portion of the damaged core. The tooling design details are recorded in drawings, test reports, and procedures too voluminous for causal comprehension. This paper describes the tools and equipment actually used for the core region defueling. Particular attention is given to defining lessons learned in the design and application of the defueling tooling
