“…The latter differentiates itself from the former by having a conversion step of phosphates to hydroxides using concentrated sodium hydroxide, followed by a milder acid leaching step. This is preferable since it allows for a better control of thorium and uranium present in the stream, which are much easier to separate via this process (Ekberg, 2015). Separation of the REEs from the leachates is done using solvent extraction.…”

“…Beyond this, naturally occurring 232 Th is also fertile, and utilising the world's combined uranium and thorium reserves would result in energy security for thousands of years. (Reactors based on thorium fuels and the associated thorium fuel cycle are outside the scope of this review, but see, for example, references [8][9][10][11]. )…”

Globally, around half a million tonnes of spent nuclear fuel (SNF) will be in dry or wet storage by around 2050. Continued storage is not sustainable, and this SNF must eventually either be disposed (the open nuclear fuel cycle) or recycled (the closed fuel cycle). Many international studies have addressed the advantages and disadvantages of these options. To inform this debate, a detailed survey of the available literature related to environmental assessments of closed and open cycles has been undertaken. Environmental impacts are one of the three pillars that, alongside economic and societal impacts, must be considered for sustainable development. The aims are to provide a critical review of the open literature in order to determine what generic conclusions can be drawn from the broad base of international studies. This review covers the results of life cycle assessments and studies on waste arisings, showing how the management of spent fuels in the open and closed cycles impact the environment, including the use of natural resources, radioactive waste characteristics (heat loading, radiotoxicity and volume) and the size of the geological repository. In the framework of sustainable development, the next part of this review will consider economic impacts.
