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.

This paper will demonstrate the potential of modern design for additive manufacturing by using computational fluid dynamics with design optimization. The Transformational Challenge Reactor Instrumentation and Control (I&C) Team has specifically requested that an instrumentation plane be designed for monitoring of the core-coolant-flow average temperature within ±5°C of the core outlet average temperature. However, because of systemwide constraints, this design space is allotted a pressure drop of only 0.5 psi. A successful design optimization study is discussed along with the thought process leading to the successful conclusion of an I&C plane with an average temperature of 497.3°C and a standard deviation of 1.03°C, all while maintaining a 3.38-kPa (0.49-psi) pressure drop across the outlet plenum.
