Environmental Tritium. Its Behavior and Utilization.

Tritium Behavior and Modeling in Man

INTRODUCTION Since, in future fusion reactors, the activity of tritium handled as the fuel is enormously large, i.e., about 10 TBq per a fusion reactor power of 1000 MW, it is necessary to develop more excellent handling technique of tritium and to store the research results related to the fusion reactor technology. In particular, it is expected that researchers and workers of the fusion reacto...

Nonholonomic Behavior in Free-floating Space Manipulators and its Utilization

The kinematics and dynamics of free-floating manipulators are examined from a fundamental point of view. The dynamic coupling between an uncontrolled spacecraft and its manipulator can make a system dynamically singular at configurations which cannot be predicted by the system’s kinematic properties. Nonholonomic behavior is observed in free-floating systems, and is due to the nonintegrability ...

Utilization of Kinetic Isotope Effects for the Concentration of Tritium

Environmental tritium contamination from a gaseous tritium light device maintenance facility

An investigation was undertaken in relation to the contamination of a facility used for the servicing and refurbishment of gaseous tritium light devices. While it is generally accepted that there is minimal exposure hazard from a broken gaseous tritium light source after the tritium gas has dispersed, environmental tritium contamination displaying ‘particulate’ like characteristics was observed...

Assessing Environmental Literacy and its Relationship with Environmental Ethics

Background: Attention to environmental literacy and ethics in agriculture has a decisive role in nature conservation and production resources. If farmers do not have environmental literacy, irreparable damage to the environment is expected. The purpose of this study was to evaluate environmental literacy and its relationship with environmental ethics among farmers in Torbat-e-Heydariyeh. Metho...
