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.

A study group comprising personnel from seventeen industrial organizations and working at Brookhaven National Laboratory has evaluated the Liquid Metal Fuel Reactor (LMFR) concept, and has prepared a preliminary design of a large central station power plant feasible for construction in the near future. This paper presents the important characteristics of that design, together with discussions of the economics and of the remaining research and development work required. The plant utilizes a 550 Mw reactor with a circulating fuel solution of U233 dissolved in bismuth and a breeder fluid of thorium bismuthide dispersed in bismuth. Two-thousand (2000) psig, 975°F steam is delivered to a turbo-generator plant, producing 226,000 kw of net electrical power. Power costs, based on both single plants and multiple units utilizing common chemical processing facilities, range from 6.5 to 8.5 mils/kw-hr.
