Atmospheric retention passive system for nuclear buildings

摘要: The passive system is suitable for prefabrication and installation as a variable volume unit enclosing industrial components, systems, buildings structures at operating light water reactors without interference with the design basis operations performance of buildings, structures, systems components enclosed. This invention removes energy from residual heat hydrogen generation accumulated inside containment spent fuel pool challenged by over temperature pressure during severe accidents, while encapsulating radioactive atmospheric fallout, condensing steam exchange atmosphere retaining resulting coolant. also encapsulates accidents releases such release through hardened venting to atmosphere, bypass atmosphere.
