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.

In the framework of the radiation protection monitoring around DANE, the high-energy factory of the Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali di Frascati (INFN-LNF), a characterization of the neutron field was performed. As a suitable neutron spectrometer, a specially designed Bonner sphere system, whose energy range was extended up to hundreds mega-electron-volts by means of three spheres equipped with copper or lead inserts, was employed. The response matrix of the system was derived with MCNPX and experimentally validated with reference neutron fields. The neutron spectrum has been unfolded with the FRUIT (FRascati Unfolding Interactive Tool) code, a new unfolding code developed at INFN-LNF for the needs of operational radiation protection. This paper presents the results of the measurements in the DANE complex, underlying the achievements of the new unfolding code. Moreover, the impact of these kinds of measurements on routine radiation protection practices is briefly addressed.
