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.

Pyrolytic dehydrochlorination of the electrical cable insulation Hypalon was studied as a function of time and temperature. The chlorine evolution was determined separately by means of on-line activity measurements and by neutron activation analysis in the temperature range 200°C to 300°C, with one test conducted at 500°C. The object of the research was to determine the chlorine release and the chlorine release fraction as a function of temperature. The data obtained were needed to formulate conclusions regarding the release mechanisms of chlorine. Estimates of the amount of hydrochloric acid released to the containment building in a severe reactor accident were also calculated. It can be concluded that the amount of chlorine release from the Hypalon cable is significant and will have an effect on iodine behavior in a severe accident.
