A Method of Building Multi-MCR in One Validation Facility

In designing digital main control rooms, a validation facility is used essentially for HFE V and V (verification and validation), which contributes to design optimization of MCR. For high reliability of validating an MCR, a validation facility should represent the characteristics of the specific MCR as precisely as possible. KHNP CRI has a validation facility by the name of 'APR-MCR@CRI', which played a role of supporting MCR design and HFE validation for APR1400-type plants. Though all the plants are adapted for the same APR1400-type MCR, there are design differences between the plants. Therefore APR-MCR@CRI should be adapted appropriately to validate respectively according to MCR designs of the specific plants (e.g. SKN3 and 4 or SHN1 and 2). Design validation and HFE verification of digital MCR are continuously performed from the early phase to the final phase of design. The validation of design before design decision is mainly fulfilled in the validation facility, it is essential to build the validation facility corresponding to the specific MCR. APR-MCR@CRI is a validation facility for APR1400-type MCR and has been upgraded to easily accept the characteristics of multiple MCR environments. The facility will be used to validate SKN5 and 6 and SHN3 and 4, and to train operators. Also, the facility is expected to usefully apply to validation of the former plants in design changes
