Success of South-Ukraine NPP Feedwater Flow and Steam Generator Level Control System (FWCS)
Based on "Vulkan-M" Hardware Start-Up and SAT

November 10, 2003

Within the period of October 1 – November 7 of 2003, South-Ukraine NPP Unit 3 Feedwater Flow and Steam Generator Level Control System (FWCS) installation, start-up and SAT were successfully performed on SUNPP Unit 3 steam generator feedwater unit regulators upgrade project and in line with works schedule on Unit 3 startup after its outage.

FWCS based on "Vulkan-M" hardware is designed and manufactured by Westron, the chief designer of the system. FWCS control algorithms (functional design) and control algorithms implementation program are developed by LvovORGRES. Emerson provided the shipment of FISHER control valves along with electric drives and positioners.

FWCS start-up and SAT were successful, without comments. FWCS meets the project steam generator level regulators and Turbine Driven Feedwater Pump productivity regulators specifications. FWCS tests demonstrated the system functioning in all Unit 3 modes. FWCS proper functioning was also demonstrated while Turbine Control System electrical subsystem testing at circulating pump switch off and Unit switchover to its local needs.

After Unit 3 startup, FWCS regulators have been running in the auto mode. FWCS putting into its pilot operation is planning until the end of November of the current year.

Rovno NPP "Vulkan-RM3" System FAT

November 10, 2003

On November 5-6, 2003, Westron successfully performed "Vulkan-RM3" System FAT (first phase of shipment). "Vulkan-RM3" System is designed for Rovno Unit 3 Radiation Monitoring System (ASRK) upgrade. "Vulkan-RM3" System activities are fulfilled on the agreement on shipment of equipment for measuring channels for radiation parameters important for Rovno NPP Unit 3 safety concluded between Westron and Atomkomplekt of NAEK ENERGOATOM. The System installation and start-up shall be completed at
Rovno NPP Unit 3 in December 2003.

State Nuclear Regulatory Administration of Ukraine
Approved "Vulkan-M" Hardware Technical Specifications

September 1, 2003

State Nuclear Regulatory Administration of Ukraine has approved technical specifications on "Vulkan-M" hardware developed and manufactured by Westron.

"Vulkan-M" hardware has successfully passed through all required tests. "Vulkan-M" hardware acceptance test was performed by commission assigned by order of NAEK Energoatom. State Scientific and Technical Center of Nuclear and Radiation Safety provided expert assessment of "Vulkan-M" hardware documentation.

"Vulkan-M" hardware is designed for a versatile NPP I&C control and information systems and other industrial applications. "Vulkan-M" is designed to take advantage of innovative approaches to systems design and building and future developments of electronics and software. Westron has developed product with the capabilities to facilitate the systems installation, setup and operation to meet the requirements of the customers. The key issue of Westron was to minimize cost and improve operating characteristics of the systems based on "Vulkan-M" hardware.
