A boiling water reactor having an optimum combination of active and passive safety systems. By combining three active divisions (I,II,III)of the boiling water reactor with a passive fourth division, the resulting design achieves improved plant reliability in addition to on-line maintenance of the emergency core-cooling systems. Included in the passive division is a new component, the reactor heat removal condenser (48), to be used in conjunction with pressure release valves (50) to provide backup depressurization of the reactor pressure vessel and backup heat removal and inventory control. The operating pressure of the heat removal condenser is maintained in the range of 100-200 psi.
