IAEA again raises global nuclear power projections
Noting recent momentum behind nuclear power, the International Atomic Energy Agency has revised up its projections for the expansion of nuclear power, estimating that global nuclear operational capacity will more than double by 2050—reaching 2.6 times the 2024 level—with small modular reactors expected to play a pivotal role in this high-case scenario.
IAEA director general Rafael Mariano Grossi announced the new projections, contained in the annual report Energy, Electricity, and Nuclear Power Estimates for the Period up to 2050 at the 69th IAEA General Conference in Vienna.
In the report’s high-case scenario, nuclear electrical generating capacity is projected to increase to from 377 GW at the end of 2024 to 992 GW by 2050. In a low-case scenario, capacity rises 50 percent, compared with 2024, to 561 GW. SMRs are projected to account for 24 percent of the new capacity added in the high case and for 5 percent in the low case.

Solutions for the RF heating problems in HANBIT mirror machine have been obtained by analytically under the assumptions of uniform plasma and magnetic field [1]. For the case of non-uniform plasma and magnetic field, a numerical calculation for entire region requires considerable computing times and delicate considerations of the antenna current. In this work, we developed a hybrid method in solving the RF heating problem in which the outer region of the plasma limiter including the antenna is treated by an analytic technique and the plasma region is solved by a numerical method. Solutions for two regions are matched on the plasma-vacuum interface self-consistently without loss of generality. Using this method, we can reduce the calculation time and required computer memories and present some results for HANBIT case.
