Radiation-induced electrolytic phenomena with differential radiation cell in water-cooled nuclear reactors

Supercritical Water-cooled Nuclear Reactors: Review and Status

Modern concepts of nuclear reactors cooled with supercritical water are presented together with a short history. The supercritical water-cooled CANDU ((CANada Deuterium Uranium) is a registered trademark of AECL) reactor concept is fully discussed. Also, thermophysical properties at critical and supercritical pressures as well as heat transfer and hydraulic resistance at these conditions are pr...

Comparison of COX2 expression in radiation induced basal cell carcinoma and non-radiation induced basal cell carcinoma

Background: Radiation-induced basal cell carcinoma (BCC) can be multiple, large, and recurring, which complicates its treatment in some cases. According to reports on the role of cyclooxygenase 2 (COX2) inhibitors in the treatment or prevention of non-melanoma skin cancers and considering the fact that COX2 expression has not been evaluated in radiation-in...

Design and Development of Radiation Detectors for Nuclear Reactors

Several B lined ionization chambers with and without gamma compensation have been developed with cylindrical and parallel plate electrode geometry. These detectors have been developed after extensive studies on the optimization ofthe neutron and gamma sensitivities, the voltage /current (V/I) characteristics and the response of the detectors as a function of neutron flux. The reliability and lo...

Radiation Shielding for Fusion Reactors

Radiation shielding requirements for fusion reactors present different problems than those for fission reactors and accelerators. Fusion devices, particularly tokamak reactors, are complicated by geometry constraints that complicate disposition of fully effective shielding. This paper reviews some of these shielding issues and suggested solutions for optimizing the machine and biological shield...
