Comparison of (Th-233U) O2 and (Th-235U) O2 fuel burn up into a thermal research reactor using MCNPX 2.6 code

Background: Decrease of economically accessible uranium resources motivates consideration of breeding of fertile elements such as thorium. Material and Method: Thorium oxide fuel burn up calculation of a simulated research reactor cooled heavy water has been proposed in the present work using MCNPX 2.6 code. Two 233U and 235U isotopes have been used as fissile element of thorium oxide fuel. 135...

Nucleon pair breaking in the thermal neutron induced fission of 233U and 235U

2014 The absence of a systematic even-odd effect in the primary fragment mass distributions, which has been recently observed, is discussed in terms of nucleon pair breaking during the saddle to scission transition. It is concluded that the existing experimental data are compatible with the assumption of a process where at least one nucleon pair is broken. J. Physique 44 (1983) 785-790 JUILLET ...

A Global Climatology of O2⋅O2, O2⋅N2, and (H2O)2 Abundance and Absorption

Recent experimental and theoretical results show that the collision pairs, O2⋅O2 and O2⋅N2, absorb a small but significant fraction of the globally incident, solar radiation (Pfeilsticker et al. 1997, Solomon et al. 1998, Mlawer et al. 1998). The contribution of the water vapor dimer to shortwave (SW) absorption, however, remains speculative due to uncertainties in both its abundance and its ab...

Proton Therapy of eye using MCNPX code

Introduction: Proton radiotherapy is the one of advanced teletherapy methods. The protons deposit their maximum energy in a position called Bragg peak. Therefore, for treatment of cancer, the tumor should be placed at the Bragg peak or SOBP. The scattered photons and neutrons is a challenge in proton radiotherapy. The aim of this study is calculation of absorbed dose from scatt...

Signaling mechanisms of elevated neutrophil O2- generation after burn injury.

A full skin thickness burn injury was produced in anesthetized rats by exposing 25% of total body surface area to 98 degrees C water for 10 s. Sham (exposed to 37 degrees C water) and burn rats were killed 1, 3, 7, or 10 days later. The role of Ca2+ signaling and Ca(2+)-related protein kinase C (PKC) activation in neutrophil O2- generation was ascertained by evaluating the effect of treatment o...
