    摘要: A reactor system of a boiling water type atomic power plant including a reactor pressure vessel, a primary containment vessel containing the reactor pressure vessel, a main turbine, a main steam piping extending through the primary containment vessel between the reactor pressure vessel and the main turbine, and inside and outside main steam isolation valves provided on the main steam piping inside and outside the primary containment vessel, respectively. A closure valve is provided on the main steam piping at a position near the primary containment vessel and is adapted to quickly close in less than 3 seconds upon a break accident of the main steam piping. A volume of the reactor pressure vessel allotted for accommodating steam is correspondingly enlarged to allow the closure valve to quickly close upon a break accident of the main steam piping.
