ACCEPTANCE TESTS OF DIGITAL SOFTWARE & HARDWARE COMPLEX OF NORMAL OPERATION SYSTEM OF REACTOR HALL (SHC NOS RH)

Acceptance tests of digital software & hardware complex of normal operation system of reactor hall (SHC NOS RH) were successfully carried out for Zaporozhye NPP power unit 5.

SHC NOS RH intended for use as a part of reactor hall normal operating system of NPP power units for supplying of technological protection functions, interlocks, alarm system, regulation and remote control of drives.

SHC NOS RH has such distinctive features as:

• reliability growth by means of using redundant structures, possibility of maintenance service of SHC in all channels with retention ability of all functions to work;
• reduction of equipment quantity by using digital means of processing and data communication in comparison with existing NOCS on the basis of unified hardware;
• reduction of equipment quantity that realize the functioning of CIS lower level of power unit by means of realization of primary processing signals in SHC and their transferring to upper level of CIS;
• reduction of cable communications quantity by using digital optical interface and it is steady against electromagnetic interference;
• presence of current and retrospective information presentation about technological parameters state, protections, interlocks, ACS, drives;;
• diagnostic of hardware states, communication links, input signals, primary and secondary electrical feed circuit;
• scalability, possibility of realization in several stages.
