Proposed FY 2027 DOE, NRC budgets ask for less
The White House is requesting $1.5 billion for the Department of Energy’s Office of Nuclear Energy in the fiscal year 2027 budget proposal, about 9 percent less than the previous year.
The request from the Trump administration is one of several associated with nuclear energy in the proposal, which was released Friday. Congress still must review and vote on the budget.

This paper discusses the feasibility of using NbTi internally cooled cable superconductor (ICCS) in the ohmic heating central solenoid for the fusion engineering device (FED). The ICCS conductor provides cryostable operation with liberal stability margin. The forced cooled concept has a high winding current density which reduces the size and the cost of the device. The forced cooled concept requires complex helium manifolding, but a unique approach has been developed to solve the problem. The conductor design, the winding design and the performance analyses are described. The solenoid is designed to operate at 8-T peak field and provides 60 MAT. The operating current for the solenoid is 21.3 kA, which is 60% of the critical current at 8 T.
