A wide variety of experiments have been carried out by twelve independent teams employing both electrolytic and gas phase loading of deuterium in Pd and Ti metals to investigate the phenomenon of cold fusion first reported by Fleischmann and Pons in March 1989. The experiments were primarily devoted to the study of the emission of nuclear particles such as neutrons and tritium with a view to ve...

Tritium RBE/Tritiated Water/CFUs/CFUc The acute effects on hematopoietic tissue in mice of a single administration of tritiated water were compared with the effects of exposure to 6OCo gamma radiation. The activity of tritium in the bone marrow was measured directly using a sample oxidizer and the absorbed dose was calculated from the amount of activity of tritium in it. The number of nucleated...

In recent years , tritium (the radioactive isotope of hydrogen) has been increasingly used as a r e search tool in chemistry, physics, biology, meteorology and hydrology. In a variety of investigations, such as the study of biological and metabolic processes, tritium or a chemical compound with tritium as one of the constituents can be used as a tracer. It is also useful in studying the effects...

Mechanisms underlying the retention of fuel species in tokamaks with carbon plasma-facing components are presented, together with estimates for the corresponding retention of tritium in ITER. The consequential requirement for new and improved schemes to reduce the tritium inventory is highlighted and the results of ongoing studies into a range of techniques are presented, together with estimate...

HCPB (Helium Cooled Pebbles Bed) Test Blanket Model (TBM) is based on solid breeder. Tritium has to be extracted using Helium purge gas flowing through breeder pebbles bed. He-stream must be cooled down and processed and all these steps are carried out in TES (Tritium Extraction System). A modeling work has been performed to study the behavior of the TES of the HCPB TBM and for Molecular Sieve ...

The introduction of tritium into hydrogenated amorphous silicon has given rise to a novel material with interesting physical properties and potential applications. Tritium undergoes radioactive decay, transforming into He and emitting an electron with average energy 5.7keV, at a rate equivalent to a half-life of 12.3 years. The decay of tritium results in the creation of electron– hole pairs an...

ALL RIGHTS RESERVED iii ABSTRACT Ghassan Badri Hamra: Bayesian methods for the evaluation of Tritium: Relative Biological Effectiveness and cancer risk. Tritium is a radioisotope of hydrogen that releases -energy, which is a form of ionizing radiation. Tritium is understudied due to a lack of epidemiological data on human exposure, despite the fact that exposure to low energy ionizing radiatio...

The Water-Cooled Lead–Lithium Breeding Blanket (WCLL BB) is one of the two blanket concept candidates to become driver EU-DEMO reactor. design was enacted with a holistic approach. influence that neutronics, thermal-hydraulics (TH), thermo-mechanics (TM) and magneto-hydro-dynamics (MHD) may have on were considered at same time. This new approach allowed for team create WCLL BB layout able compl...
