Video Transcript: Three Mile Island, Unit 2: Upper Core Damage

[Time Stamp: 00:00] Early information on post-accident conditions was obtained by visual inspections performed with miniature underwater television cameras.

[Time Stamp: 00:11] The first opportunity to view the core region damage was in 1982, when one of these miniature cameras was inserted through a control rod mechanism,

[Time Stamp: 00:19] down through the plenum, and into the upper core region.

[Time Stamp: 00:23] The operation was known as "Quick Look."

[Time Stamp: 00:27] A pile of fragments was resting on the remains of the core.

[Time Stamp: 00:31] The top of the rubble bed was five feet below the top of the original core region.

[Time Stamp: 00:36] Much of the debris was shapeless and unrecognizable.

[Time Stamp: 00:40] Scattered about in the debris were some recognizable components: springs, pieces of control rod assemblies, tops of fuel elements and rods of various length.

[Time Stamp: 00:50] The void region was five feet deep and extended in many places all the way out to the edge of the core.
