One of the techniques of minor actinides transmutation is to recycle these nuclides into fission reactors. Two concepts of a minor actinides burner reactor with very hard neutron energy spectrum as well as very high neutronjlux me discussed. The fuel cycle facilities for these burner reactors am assessed to discuss the technical feasibili~ of these reactors. Transmutation of minor actinide in b...

Psoriasis is a chronic, relapsing, cutaneous condition with a I%-2% prevalence in thegeneral population. About 40% of psoriafics report that psychosocial stress significantly exacerbates their condition. However, the clinical characferistics of the subgroup of psoriatic patients who are stress reactors have not been delineated. At a practical clinical level if is fherefore difficult to implemen...

n this paper, a mathematical model has been derived to predict the granulation time of anaerobic sludge in UASB reactors. In the proposed model, some physical, chemical and biological parameters affecting the granulation phenomena have been considered. To validate the model, 12 pilot-scale experiments in 4 UASB reactors are carried out and the results are discussed here. The reactors are starte...

Factors contributing to the proliferation resistance of CANDU reactors are examined, from the point of view of both intrinsic design features (related primarily to fuel cycle details and operational requirements), and extrinsic measures (primarily IAEA safeguards). It is shown how the technical features of CANDU reactors and fuel cycle, in most cases derived from the fundamental physics of heav...
