The passive safety systems of the AFPR include passive containment cooling system reactor isolation condenser, core flood tanks and suppression chamber tanks. [Pg.368]

This building contains the component parts of the primary coolant system, the passive decay heat removal system and the passive containment cooling system. Also present are parts of the normal residual heat removal system and the chemical and volume control system. The reactor pressure vessel holds Ihe bulk of the radioactive material present on site, in the form of the irradiated fuel within it. The principal contents of the contaimnent/shield building are the ... [Pg.45]

Passive containment cooling system storage tank and associated valves (these are within the shield building, but outside the containment vessel, with their own dedicated heating, ventilation, and air conditioning (HVAC) system, completely separate from the containment air filtration system). [Pg.45]

The engineered safety features (those subsystems and components making up the passive core cooling and passive containment cooling systems). [Pg.169]

If the secondary heat removal system is not operable then the passive residual heat removal heat exchanger, in conjunction with the passive containment cooling system, is designed to remove decay heat for an indefinite time in a closed-loop mode of operation. [Pg.191]

The passive containment cooling system is shown in Figure 6.4-1, and the passive core cooling system is shown in Figure 6.4-2. [Pg.193]

To achieve this, the containment building is made of steel to provide efficient heat transfer fi-om within to outside containment. During normal operation, heat is removed from the containment vessel by continuous natural circulation of air. During an accident, however, more heat removal is required and air-cooling is supplemented by evaporation of water, provided by the passive containment cooling system water storage tank. [Pg.197]

The major components of the passive containment cooling system are ... [Pg.197]

Additionally, a passive containment cooling ancillary water storage tank and two recirculation pumps are provided for onsite storage of additional passive containment cooling system cooling water, to transfer the inventory to the passive containment cooling water storage tank, and to provide a back-up supply to the fire protection system seismic standpipe system. [Pg.198]

Manual and automatic actuation of the passive containment cooling system is achieved via the protection and safety monitoring system. This is described in Section 6.7. [Pg.198]

Further information related with the passive containment cooling system can be found in Section 6.4 of Reference 6.1. [Pg.198]

The passive containment cooling system must be able to remove decay heat following Design Basis events and thereby keep containment pressure and temperature below the design values. [Pg.198]

After condensation of steam occurs on the steel containment vessel, which is cooled by the passive containment cooling system, the condensed water drains down through the containment wall and it is collected by the containment recirculation, thus providing sufficient makeup water for long term cooling. [Pg.207]

During normal operation the passive containment cooling system valve room ventilation fen exhausts room air to the outside environment to maintain room temperature within its normal design temperature range. [Pg.287]

When heating is required, one of the two redundant electric unit heaters provides heating to maintain the passive containment cooling system valve room temperature above its minimum design temperature. The lead electric unit heater starts or stops when the room air temperature is above or below predetermined setpoints. The standby electric unit heater starts automatically if the room air temperature drops below a predetermined setpoint. [Pg.287]

The power supplies to the passive containment cooling system valve room unit heaters are provided by the plant ac electrical system and the onsite standby diesel generators. In the event of a loss of the plant ac electrical system, the passive containment cooling system valve room unit heaters can be transferred to the onsite standby diesel generators by the operator. [Pg.287]
