ACCEPTANCE TESTS OF SOFTWARE & HARDWARE COMPLEX OF CONTROL ROD CONTROL SYSTEM RCS-IMPULSE FOR ZAPOROZHYE NPP

Acceptance tests of software & hardware complex of control rod control system RCS-Impulse for Zaporozhye NPP, power unit 2 were successfully carried out.

New system was estimated very high by NNEGC “Energoatom” experts, Ukrainian and Russian NPPs, State Nuclear Regulator Committee of Ukraine, Certification Centre of ACS, design organization.

SHC RCS-I has the following distinctive features:

• full redundancy of power supply of magnets with automatic bumpless transfering and the possibility of replacing during its running;
• realization variety of emergency and preliminary protection systems (2 three-channel complete sets, one of which is realized on “hardwired” relay logic);
• structure of SHC includes complete sets of power supply equipments (both logic and electromagnets);
• echelon facility of built-in diagnostic archive with displaying and archiving on the control and diagnostic server.

This kind of work was carried out on the base of development experience, implementation and operation of similar systems for WWER-440 power units of the Rovno NPP.
