If, as suggested by proponents, fusion small modular reactors (SMRs) can be developed faster than envisaged by the multi-national ITER/DEMO programme, the question remains as to whether such reactors will be a viable commercial proposition. Such viability will depend on a range of factors, including capital costs, income from the sale of electricity and the cost of capital. To investigate these effects, Net Present Values (NPVs) were calculated for a range of scenarios for both First of a Kind (FOAK) and Nth of a Kind (NOAK) plants supplying electricity to the United Kingdom grid commencing in 2040. Calculations have also been carried out to delineate the “space” in which positive NPVs would be obtained. These calculations show that there are combinations of capital costs, electricity prices and costs of capital in which a fusion SMR plant would be financially viable. These calculations, being based on uncertain costs and incomes, are necessarily uncertain. The calculations show that minimisation of capital costs must be a key goal for those seeking to develop a fusion SMR as a commercial proposition.

“…By it is proponents, the potential technological advantages of fusion over fission and other renewable sources are well known. However, recent studies challenge the assumption that fusion fuels, commonly cited as being abundant and geographically widespread, are without issue [28][29][30][31]. In general, the potential advantages (or disadvantages) are in need of further analysis to gain understanding fusion's impact on areas such as resource availability, job creation, GDP, and carbon footprint.…”

The commercialisation of fusion for the energy market: a review of socio-economic studies

Progress in the development of fusion energy has gained momentum in recent years. However questions remain across key subject areas that will affect the path to commercial fusion energy. The purpose of this review is to expose socio-economic areas that need further research, and from this assist in making recommendations to the fusion community, (and policy makers and regulators) in order to redirect and orient fusion for commercialisation: When commercialised, what form does it take? Where does it fit into a future energy system? Compared to other technologies, how much will fusion cost? Why do it? When is it likely that fusion reaches commercialisation? Investigations that have sought to answer these questions carry looming uncertainty, mainly stemming from the technoeconomics of emerging fusion technology in the private-sector, and due to the potential for applications outside of electricity generation coming into consideration. Such topics covered include hydrogen, desalination, and process-heat applications.

“…Tritium (H-3) is a beta particle-emitting radionuclide used in the tracer studies of sliced small animals [1,2] as well as often used in the cell proliferation studies using H-3 labeled tyrosine. H-3 is also used in nuclear fusion research [3]. H-3 is produced in nuclear power plants and its release from the Fukushima Daiichi Nuclear Power Plant (FDNPP) has been documented as a serious problem [4].…”

Imaging of bremsstrahlung X-rays from tritium water in a plastic bag using a LaGPS radiation imaging system

et al. 2020

A: Tritium (H-3) is a pure beta-emitting radionuclide and beta particles have extremely low energy (maximum energy: 18.6 keV). Thus the in-vivo imaging of H-3 is thought to be impossible. However, beta particles emit bremsstrahlung X-rays in subjects that may be imaged from outside of the subjects. We tried to image the bremsstrahlung X-rays from H-3 water using a newly developed radiation imaging system. The developed imaging system used a pixelated Ce-doped (Gd, La) 2 Si 2 O 7 (LaGPS) scintillator plate optically coupled to a flat-panel position-sensitive photomultiplier tube (FP-PMT). Using the imaging system, we conducted bremsstrahlung X-ray imaging from H-3 water in a plastic bag with 37-MBq radioactivity. We obtained tungsten slit mask images with a spatial resolution of ~3 mm full width at half maximum (FWHM). The energy spectrum of the bremsstrahlung X-rays from the H-3 water showed a broad distribution with an average energy of ~10 keV. The measured sensitivities of the LaGPS imaging system for bremsstrahlung X-rays from H-3 water in a plastic bag were 1.8 × 10 −7 . We conclude that the imaging of bremsstrahlung X-rays from H-3 water was really possible and it has a potential to be a new method for the in-vivo H-3 imaging of small animals, plants, or materials.
