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.

Requirements for Attendees: No requirements; however, attendees with SCALE 6.2 (or more recent) can participate in UQ demos, and attendees with SCALE 6.2.2 (or more recent) can participate in UQ & parametric studies demos.
Summary Paragraph: This tutorial will introduce the capabilities of the Sampler sequence, available starting in SCALE 6.2. The initial implementation of Sampler included uncertainty quantification (UQ) based on Monte Carlo sampling of multigroup nuclear data or input parameters in any SCALE sequence. The tutorial will touch on nuclear data sampling but will focus on UQ for input materials and geometry descriptions in criticality safety models. The Sampler sequence was expanded in the 6.2.2 update to include a parametric study capability. This capability is particularly useful for nuclear criticality safety evaluations and has been used extensively in recent work at Oak Ridge National Laboratory. Demonstrations of both the UQ and parametric capabilities will be included. Attendees with licensed copies of SCALE 6.2 installed on their devices will be able to follow along with presenters in the demonstrations.
