Opis:: The communication reports a serious complication connected with preparation, storage and transportation of fuel for thorium and uranium/thorium nuclear reactors. Whereas uranium fuel of any degree of enrichment is free from radium, which produces radon-222, thorium itself produces thoron (radon-220). Measurement of thoron by a routine ionization-chamber device around a small sample of 2 g thorium dioxide shows already the health endangerment situation. The presence of thoron is also confirmed by a typical solid state dosemeter (polymer CR-39), exposed to the air around ThO2 and etched afterwards with warm NaOH solution. The unavoidable presence of thoron can cause increase of price of production of nuclear fuel, demanding special approach to the method of manufacture.

Tytuł:: Nuclear fissile fuels worldwide reserves
Autorzy:: Chmielewski, A. G.
Powiązania:: https://bibliotekanauki.pl/articles/147011.pdf
Data publikacji:: 2008
Wydawca:: Instytut Chemii i Techniki Jądrowej
Tematy:: nuclear fuel

thorium
Opis:: The paper reports on the present evaluation of uranium reserves and discusses different possibilities of the efficiency of fissile fuel use including the possibility of fuel reprocessing, MOX fuel application and breeder reactors deployment. The possibility of thorium applications and uranium extraction from law grade ores and other material streams (phosphoric acid, copper leaching solution) are discussed as well.

Tytuł:: Modelling of the reactor cycle cost for thorium-fuelled PWR and environmental aspects of a nuclear fuel cycle
Autorzy:: Oettingen, Mikołaj
Powiązania:: https://bibliotekanauki.pl/articles/184223.pdf
Data publikacji:: 2019
Wydawca:: Akademia Górniczo-Hutnicza im. Stanisława Staszica w Krakowie. Wydawnictwo AGH
Tematy:: thorium

Opis:: The paper presents the methodology applied to the cost modelling of the uranium-thorium nuclear reactor cycle for PWR reactors as well as brief introduction to the environmental impact of the nuclear fuel cycle. The reactor core contains seed uranium fuel and blanket thorium fuel. In such a cycle, energy is produced in the fission of 235U included in the fresh fuel and in the fission of 233U bread from the fertile 232Th. A modified methodology developed by the OECD Nuclear Energy Agency was used for the reactor cycle cost modelling. The method is based on the levelized lifetime cost methodology for a reactor cycle, which is directly related to the heavy metal mass balance. Contrary to the case of uranium-fuelled nuclear reactors, the cost modelling includes the additional cash flow for thorium fuel. The abundance of thorium in the Earth’s crust is about 3–5 times larger than that of uranium, which suggests its promising potential as a nuclear fuel. However, this needs to be proved economically.
