I&C INTEGRATED TEST PHASE OF THE MOCHOVCE NUCLEAR POWER PLANT, UNITS 3 AND 4

This paper briefly introduces the safety instrumentation and control (I&C) system (Teleperm (R) XS) designed for the nuclear power plant in Mochovce units 3 and 4 (Slovak Republic). The overall I&C architecture of the concerned nuclear power plant is shortly introduced as well. An overview is given on the different test phases for the hardware and software I&C modules. The integrated I&C test concept and its implementation is presented as well as the description of the integrated test phase in the test bay in Erlangen (Germany). After a successful completion of the integrated test phase for unit 3, the Factory Acceptance Test (FAT) and the erection phase have been started for the concerned I&C safety systems (e.g., the Reactor Protection System and the Reactor Power Limitation System). This paper will also present the significant advantages and specifics of performing the concerned I&C tests in the aforementioned test bay.
