uranium thorium processing

Thorium nuclear fuel: 1. Introduction

Why use thorium as a nuclear fuel? The main initial motivation for the development of thorium fuel is to provide a fuel cycle that could, by replacing uranium fuel, avoid the potential of natural uranium shortage in the event of a rapid growth of nuclear power. The thorium fuel options that may be considered in light water reactors vary according to the purpose envisaged, i.e. reduction in ...

@article{osti_6570656, title = {SRP thorium processing experience}, author = {Orth, D A}, abstractNote = {In the five separate thorium processing campaigns conducted at SRP, thorium was processed in equipment and facilities which had been converted in 1959 to recover highly enriched uranium. Two different flowsheets were used and a total of approximately 240 tons of thorium and 580 kg of ...

uranium thorium processing - elektrotip.nl

Thorium Processing Reactor . Uranium mining and processing are associated with a wide range of potential adverse human health risks. Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise, whereas other risks apply to the mining sector generally and still others are linked more broadly to large-scale industrial or construction activities.

Separation of uranium and thorium from rare earths for ...

A process has been suggested by Amer et al. (2013) to separate uranium, thorium and rare earths using oxalate precipitation for processing a monazite concentrate. In a sulphate solution containing 0.147 g/L U, 2.51 g/L Th and 23.93 g/L RE, 98% of thorium and 99% of rare earths were precipitated at pH 0.7 and 60 °C, respectively, while uranium remained in the solution.

Could Thorium Power the Next Generation of Nuclear ...

Thorium Pros and Cons. Thorium was used in a lot of early nuclear physics experiments — Marie Curie and Ernest Rutherford worked with it. Uranium became more heavily associated with the nuclear process during World War II, because uranium is better for making bombs, but for power generation, thorium has some real benefits over uranium.

Thorium fuel cycle - Wikipedia

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material.In the reactor, 232 Th is transmuted into the fissile artificial uranium isotope 233 U which is the nuclear fuel.Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as 231 Th), which are insufficient to initiate a nuclear chain reaction.

Thorium-based nuclear power - Wikipedia

Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle — including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production.

Separation of thorium from uranium ore | SpringerLink

Thorium-230 has many research applications, but there is not a commercial source of this isotope. However, since 230 Th is part of the 238 U decay chain, it can be separated from naturally occurring uranium. In this work, a novel procedure was developed to separate thorium from uranium ore, consisting of leaching, liquid–liquid extraction, precipitations and ion exchange chromatography.
