Research on Initiating Events Analysis of Small Helium-Xenon Gas Cooled Nuclear Reactor

چکیده
Initiating event analysis is an essential prerequisite of conducting probabilistic safety assessment for nuclear reactors, which plays important role in improving the core design, identifying fault, and guiding operation. In order to determine initiating list SIMONS (Small Innovative helium-xenon cooled Mobile Nuclear power System), preliminary researches on initial were carried out using MLD (Main Logic Diagram) method referring theory other reactors such as HTGR (High Temperature Gas-cooled Reactor), MSR (Molten Salt PWR (Pressurized water reactor). With employing these methods, a total 31 events are identified based its latest conceptual design. These then divided into six groups according accident types, heat removal increase, decrease, abnormal reactivity distribution, pipeline crevasse equipment leakage, anticipated transients without scram, disasters (internal external). The obtained results can provide theoretical basis further SIMONS.

Deep-Earth reactor: nuclear fission, helium, and the geomagnetic field.
Geomagnetic field reversals and changes in intensity are understandable from an energy standpoint as natural consequences of intermittent and/or variable nuclear fission chain reactions deep within the Earth. Moreover, deep-Earth production of helium, having (3)He/(4)He ratios within the range observed from deep-mantle sources, is demonstrated to be a consequence of nuclear fission. Numerical s...

Tehran Research Reactor (T.R.R.) is a pool-type, 5 MW thermal research reactor. One probable event is that if some external objects or debris fall down into the reactor core and cause obstruction of the coolant flow through one of the fuel assemblies, decreasing the surface flow area, ceases the coolant flow, and also raises the fuel and sheaths tempe...
