Nuclear reactor melt protection and cooling device

摘要

Example embodiments provide a Basemat-Internal Melt Arrest and Coolability device (BiMAC) (100) that offers improved spatial and mechanical characteristics for use in damage prevention and risk mitigation in accident scenarios. Example embodiments may include a BiMAC having an inclination of less than 10-degrees from the basemat floor (62) and/or coolant channels (130) of less than 4 inches in diameter, while maintaining minimum safety margins required by the Nuclear Regulatory Commission.
