Westron has concluded with Westinghouse Electric Company the contract on manufacture and supply to Kozloduy NPP Unit 5 the hardware and software for the data links between Computing Information System (CIS) upgraded by Westinghouse and operational In-Core Monitoring System (ICMS) and Radiation Safety System (RMS).

Westron manufactures a wide range of electronic digital data links hardware applied for nuclear and fossil power plants I&C Systems.


Westron has completed manufacture, shipment and integration of Safety Parameter Display Systems (SPDS) hardware into Rovno, Zaporozhye and Khmelnitskiy nuclear power plants full-scale simulators. The shipment of equipment for South Ukraine NPP simulator is planning in the first quarter of 2002.


Westron has completed the development and verification of the new "Accolade" system software package for its application on "Vulkan" (WDPF) platform. This package was developed with the participation of Westinghouse personnel. "Accolade" software package, functionally similar to WDPF system software, allows to ensure operation in Solaris 8 operating system media for the new advanced Sun Sun Blade hardware platform equipped with the new 64-bit UltraSPARC[tm] processor. "Accolade" software package is compatible with widely used Solaris 2.5.1 and 2.6 operating systems and Sparc 5, Sparc 20, Ultra 1, Ultra 5, and Ultra 10 hardware platforms. Thus, "Accolade" system software package allows not only create new systems based on workstations of new generation, but provides successful support for the commissioned systems and enhance them.

"Accolade" software package was verified on the basis of Sizewell NPP I&C System simulation and maintenance test bed modified to fit greatly the configuration of Ukrainian VVER-1000 CIS high level to be upgraded on the basis of implemented Safety Parameter Display Systems (SPDS). Presently, "Accolade" package is in the process of its thorough verification on Westron's Software Development System (SDS).

"Accolade" software package will be applied for the first time in Leningrad Units 3 & 4 SPDS systems to be shipped to LNPP in 2002.



Within the period of September–December 2001, Westron rendered services to RSV–Radiozavod, state enterprise (Kiev), on the development of the QMS of the plant to organize it according to ISO 9001:2000. Westron submitted proposals on the QMS development and implementation, gave recommendations on quality procedures development and implementation, and provided samples of Westron's basic procedures. These activities were performed within the bilateral agreement between RSV–Radiozavod and Westron.


Westron within the period of April 16-26, 2002 provided Safety Parameter Display System (SPDS) equipment shipment and its integration into South Ukraine NPP Unit 3 full-scale simulator.
SPDS integration into the full-scale simulators of all Ukrainian nuclear power plants (ZNPP, RNPP, KhNPP and SUNPP) is completed.



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.
In CRPDDS start-up works ZNPP and Westron, the subsystem developer and supplier, took participation.
CRPDDS implementation on the ZNPP Unit 6 ECR meets the requirements of section 2.4.13 of the Nuclear Safety Regulations RY AS-89 and the General Safety Regulations related to the scope of control rods position display on ZNPP Unit 6 ECR, and also provides control rods position display for ECR personnel in the same scope as this data is displayed on reactor operator and turbine operator SPDS workstations on VVER-1000 Main Control Rooms.


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.

Westron has appraised reliability of the Swedish Ringhals NPP Power Unit No.2 Turbine Monitoring & Control System

"Vulkan-M" Hardware State Acceptance Test
December 4-5, 2002

"Vulkan-M" hardware state acceptance test commission, appointed by NAEK "Energoatom" has performed the state acceptance test of "Vulkan-M" hardware developed by Westron.
"Vulkan-M" hardware evolved from "Vulkan" hardware is designed for the expanded applications in:
  • Nuclear area for the development of innovative or upgrade the available I&C Information and Control Systems of Safety Classes 2, 3 and 4
  • Nonnuclear area for the development of innovative or upgrade the available Information and Control Systems for heat and hydro- power generating field and other industries

"Vulkan-M" controller cabinets ensure input/output and processing of the wide range of up to 360 analog or up to 720 discrete signals in any combination. The capabilities are available to connect up to 2 extension cabinets to the processor cabinet. Each extension cabinet includes the same components that houses the processor cabinet (with the exception of processor cards) to expand the processor cabinet capacity. Information and Control Systems based on "Vulkan-M" hardware may comprise up to 32 controller cabinets (two extension cabinets may be connected to each of the controller cabinets) which total capacity is up to 30,720 analog or up to 61,440 discrete signals in any combination.

"Vulkan-M" hardware completely meets the requirements of the regulatory documents of Ukraine, including the nuclear and radiation safety requirements defined for the NPP hardware of Safety Class 2. "Vulkan-M" hardware design addresses the needs of the customers and simplifies the systems installation, start-up and commissioning on site.

"Vulkan-M" hardware applies the state-of-the-art components of the world leading manufacturers, such as Motorola, Analog Devices, Traco, Atmel, and Cypress, and the advanced technical solutions that allows to improve considerably the technical characteristics and life time of the systems based on "Vulkan-M" hardware in comparison with the commercial grade hardware available on the Ukrainian market. "Vulkan-M" design documentation is developed to provide capabilities of replacement of the applied components by the ones with the adequate functions of other manufacturers, which can be easily purchased in Ukraine.

"Vulkan-M" hardware was subjected to all the acceptance tests required by the regulatory documents of Ukraine. On the bases of the test results "Vulkan-M" hardware state acceptance test commission acknowledged the possibility to start "Vulkan-M" hardware production in case if the additional tests on resistance to electrostatic discharge and microsecond and nanosecond pulse interferences are performed to confirm meeting the Safety Class 2 requirements.
