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.

After the serious accident happened in March, 2011 at Fukushima Dai-ichi Nuclear Power Plant, various countermeasures are required and have been carried out. Regarding the radiation monitoring, the reinforced environmental resistance, additional monitoring equipment for the additional facilities and the diversity of monitoring principle with the existing monitoring devices are the scope of improvement. Hitachi, Ltd. and Hitachi-GE have been developing a fiber optic radiation monitor using a neodymium-doped yttrium aluminum garnet (Nd:YAG) crystal and Eu3+ doped gadolinium tantalate (GdTaO4:Eu) crystal. Prototype monitors have been developed and their performance evaluation was carried out. As a result of the evaluation, fiber optic radiation monitors show very good characteristics for a nuclear power plant use. Therefore, we advanced a study about system constitution applying these detectors. In particular, system constitution plan and characteristics are listed in this paper in the case of CAMS, ARMS and monitoring post. Finally, the future prospects of the optic fiber radiation monitor are mentioned.
