South-Ukraine NPP Unit 2
Computer Information System "Vulcan-CIS/SPD-2"
Site Acceptance Test Has Been Successfully Completed

May 17, 2005

New integrated Computer Information System (CIS) based on "Vulcan-CIS/SPD-2" Distributed Computer System developed and manufactured by Westron has been put into pilot operation at South-Ukraine NPP Unit 2.

SUNPP Unit 2 CIS replacement has been performed in line with NAEK "Energoatom" NPP I&C upgrade schedule. The shipment of hardware components for CIS Upper Level manufacture was provided on International Nuclear Safety Program (INSP). For CIS Low Level hardware manufacture part of Chernobyl NPP Safety Parameter Display System (SPDS) hardware was used. Some CIS Low Level subsystems are based on Westron's serial "Vulcan-M" hardware.

The process of CIS replacement was performing simultaneously with SUNPP Unit 2 SPDS upgrade and its integration with CIS. SUNPP Unit 2 integrated CIS start-up and its put into operation were provided by the personnel of Westron and SUNPP during Unit 2 outage in April-May, 2005.

"Vulcan-CIS/SPD-2" SAT results have demonstrated the advanced performance characteristics of the system and its complete conformity with its technical requirements.

SUNPP Unit 2 Computer Information System (CIS) Has Been Replaced

CIS SAT was completed on May 16, 2005. CIS Upper Level upgrade is provided on one of the nuclear safety technical aid projects arranged by USA. CIS hardware was supplied by Westinghouse, the world famous company.

SUNPP has performed CIS Low Level replacement at the second "million-kilowatt" Unit at its own expense. The decision was made to use some hardware earlier supplied by the American company for Chernobyl NPP Unit 3 Safety Parameter Display System (SPDS). This approach has provided the opportunity to make the project $2,5 millions cheaper and has allowed completely replacement of the hardware which resources have been exhausted.
The personnel of Westron (Kharkov), a long-standing partner of South-Ukraine NPP, was involved jointly with the personnel of SUNPP Thermal Instrumentation Control and Service and a number of subcontractors in the process of CIS replacement. CIS replacement project was not the first joint project for SUNPP and Westron. Westron's personnel were involved in implementation of a number of SUNPP upgrade projects.
The similar reconstruction was performed on SUNPP Unit 1 in 1998. SUNPP personnel highly praised the reliable 7 years operation of the American equipment.
This year the first phase of SUNPP Unit 3 CIS upgrade will be realized.

One More Phase of Rostov NPP CIS Upgrade Project is Completed

May 4, 2005

Westron has completed the next phase of works on Rostov NPP Unit 1 Information & Computer System (CIS) upgrade project on contract with Research Institute for Nuclear Power Plant Operation (VNIIAES), Moscow. In April, during Rostov NPP Unit 1 outage, the supplementary diagnostics of "Vulkan-GS" Gateway System was implemented that will permit Unit personnel to receive on-line detailed diagnostic data on M-64M information complex and "Vulkan-GS" hardware status.

"Vulkan" hardware based "Vulkan-GS" Gateway System is designed by Westron to provide communications between the upgraded CIS Upper Level and Data Acquisition and Processing Subsystem based on M-64M. "Vulkan-GS" is operational at Rostov NPP since 2003.

"Vulcan-RM1" Radiation Monitoring System (RMS) installation has been completed and its start-up is in the progress in the scope of measuring channels for ZNPP Unit 1 Safety System 2 radiation parameters. Westron has provided the scheduled shipment of "Vulcan-RM1" hardware for upgrade of measuring channels for ZNPP Unit 1 Safety System 1 radiation parameters.

Radiation Monitoring System Hardware Shipment to Rovno NPP

April 28, 2005

Westron has shipped Radiation Monitoring System (RMS) hardware to Rovno NPP (RNPP Units 1 & 2 MCR and ECR Exposure Rate Monitoring System and RNPP Units 1, 2 and 3 Heat Network Radionuclid Protection System) in line with the comprehensive NPP Units modernization and safety improvement program approved by the cabinet of ministers of Ukraine. RMS hardware manufacture and shipment are provided on contract with Atomkomplekt of NAEK Energoatom.

Kickoff Meeting on TACIS Project at SUNPP

April 12, 2005

The representatives of Westron took part in a kickoff meeting on TACIS project U1.02/01A that took place on April 7 at South-Ukraine NPP. Westron performs works on development of Automatised Chemistry Control and Diagnosis Expert System for SUNPP on this TACIS project.

The official web site of NAEK "Energoatom" of April 11, 2005 states as follows:

"The other day a kickoff meeting on one of the international technical aid projects was held at South-Ukraine NPP. This project on upgrade of SUNPP Primary and Secondary chemistry controls is implemented on TACIS program. The Automatised Chemistry Control and Diagnosis Expert System will be developed, the new reactor boron concentration devices will be installed on SUNPP Units 1 & 2, and some other works will be performed on this project.

More than 10 companies and organizations are involved in this project. Presently, the Technical Requirements are being developed. It is assumed that the project will be implemented during three years, including the current year."
