Manufacturing Technology of Ceramic Pebbles for Breeding Blanket

Breeding blanket concepts for fusion and materials requirements

This paper summarizes the design and performances of recent breeding blanket concepts and identifies the key material issues associated with them. An assessment of different classes of concepts is carried out by balancing out the potential performance of the concepts with the risk associated with the required material development. Finally, an example strategy for blanket development is discusse...

Estimation of Occupational Exposure during Ceramic Manufacturing

Introduction: The present study investigated the relatively high concentrations of natural radionuclides in raw material that used in ceramic manufacturing, and estimated the occupational exposure due to these activity concentrations. Material and Methods: A high-purity Germanium detector was used to determine naturally occurring radionuclide...

An assessment of models for tritium release from ceramic breeders for blanket analysis applications

Several models have been proposed and used to analyse the tritium release from ceramic breeder blankets. The transient models range from single-mechanism types of models to comprehensive, fully integrated models over a blanket spatial location, including all the key transport mechanisms, as well as local spatial temperature gradients. This paper considers different models available for analysis...

Lithophagia: pebbles in and pebbles out.

Fig. 1 : X-ray abdomen of the patient showing pebbles in rectum and the anal canal 35 year old male patient hailing from Sivani, madhya Pradesh had come with complaints of passing watery stools, dull aching pain in the abdomen since 10 to 15 days. Patient had been a case of mental retardation since childhood. he was noticed passing pebbles along with passage of watery stools. On further enquiry...
