One of the main characteristics of heavy water research reactors is their high production of plutonium. This work demonstrates the possibility of reduction of plutonium production and other actinides in heavy water research reactors. Among the many ways for reducing plutonium production in a heavy water reactor, in this research, changing the fuel from natural uranium to thorium-uranium mixed f...

Effects of Early Administration Times of Injected Ca-DTPA on Removal of Inhaled Plutonium Nitrate in Rats

INTRODUCTION The crucial moment of Ca-DTPA (calcium salt-diethylenetriaminepentaacetic acid) therapy for the removal of inhaled plutonium is the timing of the first injection. This is because DTPA acts on plutonium while it is in the blood, this action is lost after plutonium has been deposited into the organs. It is, therefore, generally accepted that chelation therapy should be started as ear...

Relativistic density functional theory modeling of plutonium and americium higher oxide molecules.

The results of electronic structure modeling of plutonium and americium higher oxide molecules (actinide oxidation states VI through VIII) by two-component relativistic density functional theory are presented. Ground-state equilibrium molecular structures, main features of charge distributions, and energetics of AnO3, AnO4, An2On (An=Pu, Am), and PuAmOn, n = 6-8, are determined. In all cases, m...

Developing a physiologically based approach for modeling plutonium decorporation therapy with DTPA.

PURPOSE To develop a physiologically based compartmental approach for modeling plutonium decorporation therapy with the chelating agent Diethylenetriaminepentaacetic acid (Ca-DTPA/Zn-DTPA). MATERIALS AND METHODS Model calculations were performed using the software package SAAM II (©The Epsilon Group, Charlottesville, Virginia, USA). The Luciani/Polig compartmental model with age-dependent des...
