CONTROL RODS POSITION DATA DISPLAY SUBSYSTEM FOR ZAPOROZHYE NPP UNIT 6

Within the period of May 7-15, 2002 Control Rods Position Data Display Subsystem (CRPDDS) start-up on ZNPP VVER-1000 Unit 6 Emergency Control Room (ECR) was successfully performed.

In line with the Agreement between ZNPP and Westron the similar CRPDDS subsystems shall be implemented on all ZNPP Units in 2002-2003.

MULTY UNIT SPDS PROJECT

Zaporozhye NPP Multi Unit Safety Parameter Display System (MUS SPDS) putting into its pilot operation was a success. Its Site Acceptance Test (SAT) was performed within the time period of May 12–15, 2002.

SAT commission included the representatives of NAEK "Energoatom", Zaporozhye NPP Westinghouse, Burns&Roe, Westron, KhIEP, and NPP Operation Support Institute (OSI).

Five year program on the development of Safety Parameter Display Systems for the Ukrainian VVER-1000 Units is completed.

Within the scope of this program eleven Unit SPDS systems and one Zaporozhye NPP MUS SPDS system were implemented and are successfully operating at the four Ukrainian NPPs (Zaporozhye NPP, South Ukraine NPP, Rovno NPP, and Khmelnitskiy NPP).

Two Unit SPDS systems for SUNPP have become commercial. The commissioning of the remained Unit SPDS systems is planning in 2002-2003.
