An assessment of thorium and spent LWR-fuel utilization potential in CANDU reactors
A neutronic analysis has been performed to assess a prospective utilization of light water reactor (LWR) spent fuel in Canada deuterium uranium (CANDU) reactors mixed with thoria (ThO2). The study is conducted for mixture ... -
CANDU reactor as minor actinide/thorium burner with uniform power density in the fuel bundle
Şahin, Sümer; Yalçın, Şenay; Yıldız, Kadir; Şahin, Hacı Mehmet; Acır, Adem; Şahin, Necmettin (Pergamon-Elsevier Science, 2008)A CANDU reactor fueled with a mixed fuel made of thoria (ThO2) and nuclear waste actinides has been investigated. The mixed fuel composition has been varied in radial direction to achieve a uniform power distribution and ... -
The effects of neutron energy-group structures and resonance treatment on integral parameters in a fusion breeder blanket fuelling with ThO2
The purpose of this work is to investigate the effects of neutron energy-group structures and resonance treatments on the main integral neutronic parameters in a fusion-fission hybrid reactor, which has a fast and a thermal ... -
Effects of spectral shifting in an inertial confinement fusion system
Şahin, Sümer; Şahin, Hacı Mehmet; Yıldız, Kadir; Acır, Adem (Carl Hanser Verlag, 2005)The main objective is to study the effects of spectral shifting in an inertial confinement system for kT/shot energy regime on the breeding performance for tritium and for high quality fissile fuel. A protective liquid ... -
Increased fuel burn up in a CANDU thorium reactor using weapon grade plutonium
Weapon grade plutonium is used as a booster fissile fuel material in the form of mixed ThO2/PuO2 fuel in a Canada Deuterium Uranium (CANDU) fuel bundle in order to assure the initial criticality at startup. Two different ... -
Investigation of CANDU reactors as a thorium burner
Large quantities of plutonium have been accumulated in the nuclear waste of civilian LWRs and CANDU reactors. Reactor grade plutonium can be used as a booster fissile fuel material in the form of mixed ThO2/PuO 2 fuel in ... -
Investigation of tritium and 233U breeding in a fission-fusion hybrid reactor fuelling with ThO2
Yıldız, Kadir; Şahin, Necmettin; Şahin, Hacı Mehmet; Alkan, Mahmut; Durukan, Okhan (ICENES, 2007)In the world, thorium reserves are three times more than natural Uranium reserves. It is planned in the near future that nuclear reactors will use thorium as a fuel. Thorium is not a fissile isotope because it doesn't ... -
Investigation of tritium breeding ratio using different coolant material in a fusion-fission hybrid reactor
Şahin, Hacı Mehmet; Tunç, Güven; Şahin, Necmettin (Elsevier Ltd., 2016)The aim of this study is to investigate tritium breeding ratio (TBR) and first wall material damage parameters such as displacement per atom (DPA), gas production of various coolants with Li2C2 tritium breeding material ... -
Minor actinide burning in a CANDU thorium reactor
Şahin, Sümer; Yıldız, Kadir; Şahin, Hacı Mehmet; Acır, Adem; Şahin, Necmettin; Altınok, T. (HANSER eLibrary, 2006)Nuclear power plants are producing nuclear waste materials in substantial quantities, which represent a hazard potential for future generations.
