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.

It is an urgent demand to find an alternative model to replace the actual tube bundles area when using numerical simulation to study the Intermediate Heat Exchanger(IHX) of a Sodium-cooled Fast Reactor. An appropriate alternative model can be a substitute for the actual model of IHX in terms of heat transfer and fluid flow. Dual-mesh coupled heat transfer is used based on the porous media model in FLUENT to simulate the flow field of a simple shell-tube heat exchanger and get temperature, velocity and pressure field data of the primary and the secondary fluid simultaneously. The result meets well with that acquired from the calculation of an actual model which proves that the method in this paper is reliable and is able to reduce the modeling and meshing work.
