Zaporozhye Nuclear Power Plant Unit 4
Safety Parameter Display System "Vulkan" DCS Pilot Operation

On April 18, 2001 the Site Acceptance Test (SAT) of SPDS "Vulkan-SPD-8" Distributed Computer System (DCS) on Zaporozhye NPP Unit 4 successfully resulted in the DCS pilot operation.

In the DCS SAT performance the representatives of NAEK "Energoatom", State Nuclear Regulatory Administration of Ukraine, Burns & Roe, Westinghouse, Westron, NPP Operation Support Institute, KhIEP, and Crimea Scientific and Technical Center took part. South Ukraine NPP representatives were also present.

It's the forth DCS which was put into operation at Zaporozhye NPP and the ninth one put into operation on the Ukrainian VVER-1000 NPPs within the International Nuclear Safety Program. The similar Zaporozhye NPP Units 1 and 6 DCSs are planning to be implemented in 2001.

Creation of Zaporozhye NPP Multi Unit SPDS in 2001-2002 will be the next step of the Program implementation.

It's worth mentioning that it was for the first time when the DCS SAT coincided with putting of the Zaporozhye NPP Unit 4 on the normal power operation after the reactor trip. DCS and Unit data complete adequacy demonstrated the DCS proper operation and was a real success.
