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.

The results of a transmission experiment on a spherical nickel shell with a 7.5-cm-thick wall and a 14-MeV neutron point source at the center are reported. The neutron leakage spectrum from 14 MeV down to 100 keV was measured by the time-of-flight (TOF) method. Descriptions of the experimental arrangement, TOF spectrometer, measurements, and data-reduction procedures are given. The measured data are compared with results obtained in other laboratories. Three-dimensional Monte Carlo calculations with the MCNP code using the FENDL-1, EFF-2.4, and JENDL-FF nuclear data libraries were made. The FENDL-1 library predicted the neutron leakage from nickel more accurately than the other libraries.
