The Russian federal budget allocates over 30 ₽ billion for the International Thermonuclear Experimental Reactor (ITER) project between 2027 and 2029. These figures were disclosed in the explanatory note to the draft budget submitted to the State Duma.

Funding is distributed across two main budget categories. Under the general government issues section, the state plans to provide 2.03 ₽ billion in 2027, 1.32 ₽ billion in 2028, and 1.35 ₽ billion in 2029.

The national economy section accounts for the largest portion of the investment, with allocations of 7.83 ₽ billion in 2027, 9.04 ₽ billion in 2028, and 9.19 ₽ billion in 2029. The total expenditure for the three-year period is estimated at 30.76 ₽ billion.

The peak of the planned funding will occur in 2029, when the project is set to receive approximately 10.54 ₽ billion. Russia remains a key participant in the ITER initiative, contributing high-tech components and systems to the reactor facility located in France.
