All of these materials are transported on land, sea or in the air in compliance with regulations which are now universally based on the IAEA Regulations for the Safe Transport of Radioactive Materials Ref. [1]. These regulations are designed to ensure adequate protection of transport workers, the public and the environment against the hazards of external radiation, the spread of radioactive con...

Thermodynamic and electrochemical properties of actinides in molten fluoride salts are one the key data required for design safety assessment any salt reactor concept using liquid based fuel. In case Molten Salt Fast Reactor (MSFR), special attention has to be paid thorium fluoride, which is a direct fuel carrier constituent. This work presents experimental measurement ThF4 activity coefficient...

At present work, under initial inventory with Th and U, the evolution of nuclides in subcritical devices under given thermal, fast, hardening fast and fission neutron field are studied without the detail structure of sub-critical device and the burn-up being considered. It is supposed that the subcritical reactor consists of uniform in which the flux of neutron is homogeneous. The fissile nucli...

Fast reactor fuel cycle (FRFC) is regaining importance because of its vital role in the long term development of nuclear power. The safety issues associated with the fast reactors are now well understood and newer designs can address those from the lessons learned in the past. The same cannot be ascertained about their safeguards issues. Primary reason being the presence of special nuclear mate...
