Tests of Additional Reactor Protection Circuit on Ignalina NPP

In period from May 9 to May 24, 1999 Westron together with the personnel of Ignalina NPP and representatives of Westinghouse participated in tests of Ignalina NPP Unit 1 Additional Reactor Protection Circuit (ARPC).

The tests are successfully completed.

ARPC is developed by Westinghouse on the basis of WDPF equipment and includes two subsystems: 1E Protection System; Non 1Е Auxiliary System.

In the same period Westron carried out the training of NPP personnel on the program "User of WDPF Engineer Station".

Ukrainian and American Conference in Kharkiv

On May 27-31, 1999 in Kharkiv within the framework of realization of the Ukrainian and American project "Kharkiv initiative" a business and investment conference in the field of power was held. The conference was a large event of the bilateral Ukrainian and American relations. In this conference participated the deputy minister of power of Ukraine Mikhail Umanets, President of National Nuclear Power Company "Energoatom" Nikolay Dudchenko and other top level representatives of ministries and departments of Ukraine.

From the American side participatied the Ambassador of USA in Ukraine Steven Pfifer, top level representatives of Department of State of the USA and Administration of the US President.

In the conference also took part the representative delegations of business circles of USA with participation of about 80 leading companies engaged in power generation and representing adjacent sectors of economy.

"Hartron-Enkos" design and production enterprise and "Westron" consortium took an active part seminars " New Purposes and New Decisions in Power Machinery Building", "Problems of NPP and FPP Equipment Safe Operation" and "Ecology".

At the seminar seven reports were submitted. The basic offers, submitted by "Hartron-Enkos" design and production enterprise and "Westron" consortium were the following: Modernization of the appreciable Ukrainian VVER-1000 CIS based on SPDS hardware; Replacement of "Titan" CIS on one of VVER-1000 Power Units; Development and puting into operation of the National Crisis Centre.

Program of SPDS Implementation for VVER-1000

In Westron the works within the framework of the program on implementation of Safety Parameters Display System (SPDS) at Ukrainian VVER-1000 Power Units are going on. Two pilot SPDSs (for KhNPP-1 and ZNPP-5) were developed and delivered to NPPs in 1998. KhNPP-1 SPDS site acceptance test (SAT) for putting it into operation are finished in March 1999. ZNPP-5 SPDS putting into pilot operation is planned on August 1999.

SUNPP-1 SPDS factory acceptance test (FAT) (preliminary test of the Phase 1) was successfuly completed in June 10, 1999 in Westron. The System was shipped to SUNPP in June 15, 1999. The SPDS installation works are as a whole completed at the Power Unit. After completion of SPDS start-up the System is planned for pilot operation on July 21-22, 1999.

SPDS for SUNPP-1 considerably differs from the pilot systems. It is the first SPDS for the Power Unit with reactor of В-302 type. SPDS is integrated with SUNPP-1 operating "Vulkan" CIS based on the same "Vulkan" hardware that facilitates the System operation.

The functional part of the project is developed by the experts of SUNPP jointly with the experts of Westron.

The accepted design and configuration of SPDS considerably improves functional opportunities of information systems for Power Unit operator support.

In 1999 the SPDSs are also planned for implementation at Rovno NPP (Unit 3), Zaporozhye NPP (Unit 3) and South-Ukrainian NPP (Unit №2).
