TOKAMAK FUSION TEST REACTOR (TFTR) 

 Princeton Plasma Physics Laboratory (PPPL) 

 U.S. Dept. of Energy 



"Big Science" Descriptor ; Magnetic fusion 



Description of Facility/Instrument : The TFTR is the major U.S. 



tokamak scaling experiment. It has been designed to produce 

 fusion energy at the breakeven level, using a deuterium-tritium 

 plasma. One outstanding feature of the experiment is that it 

 has 30 megawatts of neutral beam power for plasma heating. The 

 experiment will be used to study the physics of breakeven plasmas 

 and the engineering aspects of deuterium-tritium operation with 

 power densities approaching those required for a working reactor. 



Date of Construction ; 1982 



Construction Cost ; 1984 $$ : $681 million in current year dollars 



Present International Cooperation 



Natlonality(s) of Ownership ; U.S. 



Nationality(s) of Operational Funding ; U.S. 



Nationality (s) of Management Staff ; U.S. 



Nationality(s) of Researchers ; U.S., although individuals from 

 Japan, the European Community, and the U.S.S.R. have parti- 

 cipated in experiments on TFTR. 



Other Information : Construction on the main TFTR facility began in 

 1976 and was completed in 1982 with the start of operations. 

 During the operational phase, additional capacity has been added 

 to reach full capability. These additions will be completed 

 in 1986. The peak construction years were 1979-1983. The cost 

 of $681 million is given in actual (that is, year of expenditure) 

 dollars and includes all (either incurred or planned and approved) 

 costs associated with the facility, including R&D, up through 

 1986.
