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 variational method particularly suitable for the pulsed-neutron problem was suggested by Ahmed et al.; in this method, one needed the exact solution of the eigenvalue equation for two values of the buckling. In the modification we suggest, no solution of the eigenvalue equation is required; however, compared to the earlier method our results are a little less accurate. A similar variational method has also been developed for the case of neutron diffusion. As examples, we have studied the decay of a neutron pulse and neutron diffusion in beryllium and beryllium oxide blocks.
