Type One Energy, TVA ink LOI in development of fusion power in Tennessee
The Tennessee Valley Authority has issued a letter of intent to fusion energy start-up Type One Energy regarding the utility’s interest in the potential deployment of Type One Energy’s fusion power plant technology at TVA’s former Bull Run fossil plant site once it is commercially ready.

The postaccident Three Mile Island Unit 2 (TMI-2) plant was a maze of contaminated areas with varying levels of radiation. Several cubicles in the auxiliary building could not be entered for survey, much less to decontaminate. The containment basement was the most contaminated region with radiation fields up to 1100 R/h. The thousands of curies of cesium and strontium contained in the loose debris, sediment, and water made the basement a difficult region to decontaminate. To characterize and decontaminate these hazardous areas, cleanup personnel were forced to consider the use of remotely controlled (robotic) equipment. The remote equipment program at TMI-2, driven by need, resulted in considerable reduction of radiation exposure to plant personnel. The remotely operated devices developed under this program and the general criteria formulated for each design are described.
