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 knowledge-based expert system was developed for generating a pressurized water reactor fuel reload design. First, an initial loading pattern was generated according to the fuel assembly's infinite multiplication factor, by using heuristic rules. Then, the fuel assembly was swapped or rotated, using heuristic rules, to satisfy an assumed search target. The search target was the defined nuclear enthalpy rise hot-channel factor FH at each fuel assembly location. When FH's of a trial loading pattern satisfied the search target, the pattern met the design limit at each exposure checkpoint for all control rods out and D-bank control rods half-inserted conditions, which is the design requirement. The developed program successfully generated several reload cycles for the Maanshan nuclear power plant in Taiwan.
