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.

Tritium benchmark experiments with D-T neutron are a key issue to verify the tritium production rate (TPR) of the fusion blanket. The most useful method to measure the TPR in the neutron benchmark experiments is the liquid scintillation counting with Li2CO3 pellet. Ten years ago, the method of Li2CO3 pellet has been sufficiently verified the accuracy by means of D-T fast neutron irradiation and it was concluded within 10%. However, on the recent breeding blanket design, tritium is dominantly produced with the thermal neutron made with the scattering of D-T neutron and also the accuracy of the tritium production rate is requested below 10%. Therefore, previous verification is not sufficient for the recent blanket design and it is necessary to carry out the activity of the verification again. The JAERI, ENEA and TUD began to carry out the tritium benchmark experiment to verify the tritium production rate for the recent fusion blanket.
