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.

ITER is a joint international fusion facility to demonstrate the scientific and technological feasibility of fusion power for future commercial electric power facilities. ITER is designed to reject all the heat generated in the plasma and transmitted to the in-vessel components through the Tokamak Cooling Water System (TCWS) to the intermediate closed loop Component Cooling Water System (CCWS) and then to the environment via the open Heat Rejection System (HRS) and Cooling Towers. At the present the main in-vessel components as First Wall-Blanket (FW-BLK) and the Divertor (DIV) are cooled via four separated Primary Heat Transfer Systems (PHTSs). This paper describes the proposal to integrate the PHTS for the FW-BLK and DIV in a common loop to improve the availability and reliability of the cooling system. Furthermore, the paper presents the new thermal hydraulic design parameters, the relevant Process Flow Diagram (PFD) and a study for the new arrangements of the piping in the TCWS vault. Some associated issues for safety accidental scenarios are planned to be solved before the final acceptance of the proposal in the baseline design.
