Metallographic Assesment of the Thermal Exposure to the Three Mile Island Unit 2 Reactor Lower Head

The accident at Three Mile Island Unit No.2 (TMI-2) on March 28, 1979 was the worst nuclear accident in US history. One of the tasks of the international TMI-2 Vessel Investigation Project (VIP) was to assess the integrity of the vessel. By January 1990, it was possible electrochemically to machine coupons from the lower head by using a specially designed tool.
