Compact Workstation (Operation Console)

Four identical Compact Workstations- Workstations for RO, TO, SS and STA- Access to all operating status information and controls

necessary to the operatorOne compact workstation consists of

- Four Information FPDs with pointing device- Four ESF-CCS FPDs- Four sets of confirm switches

19

Soft control

Replaces the conventional dedicated pushbuttons and M/A stations

Allows operators to conveniently access all components for safety systems as well as non-safety systems during normal operation

Safety related Soft Control is implemented on the ESF-CCS FPDs

Non-safety related Soft Control is implemented on information FPDs by selecting the corresponding control template on a display screen window

20

Typical Soft Control Template

21

Large Display Panel

Provides convenient and prompt means for MCR operators to assess the plant status during normal operation as well as abnormal conditions

Fixed section provides continuous display of plant overall status with key alarms and parameters

Variable section allows operators to selectively display information

Includes Safety Parameter Display System (SPDS) and Bypassed & Inoperable Status Indication (BISI)

22

Safety Console

Independent of the compact workstations- Provides controls and information for all class 1E, safety-related

components, independent of the compact workstations.- To be used for surveillance testing during normal operation

Minimum Inventory Switches- Perform the control function for the credited equipment for safe

shutdownQIAS-N FPD- Provides information for safe shutdown

23

IV. Licensing Issue

24

Soft Control

During the process of safety review for APR1400, Soft Control has been divided into two, i.e., the safety related and the non-safety related

Previous Soft Control- Control of safety related and non-safety related components from the non-

safety related information FPDs

Current Soft Control- Safety related ESF-CCS FPDs- Non-safety related information FPDs
