Computerized Procedure System centered HFE V&V for Shinkori Units 5&6

CPS (Computerized Procedure System) is a representative system of main control room for APR1400 type nuclear power plant. Shinkori units 3&4(SKN3&4) have been using the CPS for commercial operation for several years since 2016. Also Shinhanul units 1&2(SHN1&2) and Shinkori units 5&6(SKN5&6) are supposed to use CPS. All the CPS in SKN3&4, SHN1&2, and SKN5&6 were designed by KHNP CRI, and the CPS has been upgraded gradually for improving usability in each construction project such as SHN1&2, SKN5&6. The CPS for SKN5&6 has been upgraded based on user experience of previous plants. KHNP CRI conducted the CPS centered HFE V&V for SKN5&6 twice in 2016 and 2020~2021. This paper describes the result of CPS HFE V&V in 2020~2021. The V&V was conducted in two installments and two operation teams from SHN1&2 participated each in the V&V.
