SUNPP Unit 2 Safety System Emergency Governors Upgrade
July 12, 2007
The next phase of the South-Ukraine NPP Safety System
emergency governors upgrade in compliance with the "SUNPP Units 1 & 2 Safety
Control Systems Hardware Upgrade" Technical Decision has been completed at the
SUNPP.
The emergency governors for the 2nd Train of the SUNPP Unit 2 Safety System have been replaced by the "Vulcan-M-AP-2/2" Computer System based on the "Vulcan-M" hardware. The "Vulcan-M-AP-2/2" Computer System has been put into pilot operation.
The Safety System emergency governors based on the "Vulcan-M" hardware have been implementing at SUNPP from 2005. The upgrade of the emergency governors for the 3rd Train of the SUNPP Unit 1 Safety System in 2005, and the upgrade of the emergency governors for the 2nd Train of the SUNPP Unit 1 Safety System in 2006 were a success. The upgrade of the emergency governors for the 1st Train of the SUNPP Unit 1 Safety System is planning during the SUNPP Unit 1 outage in 2006.
SUNPP Unit 2 Automatised Chemistry
Control and Diagnosis
Expert System
Commissioning
July 17, 2007
The successful pilot operation of the SUNPP Unit 2 Automatised Chemistry Control and Diagnosis Expert System is resulted in its commissioning on July 17, 2007.
Westron has designed and manufactured the Automatised Chemistry Control and Diagnosis Expert Systems for and implemented them on all SUNPP Units on the international TACIS Program.
SUNPP Unit 2 Clock Sync System Upgrade
July 20, 2007
Westron has provided the upgrade of the SUNPP Unit 2 Clock Sync System (CSS) during the SUNPP Unit 2 outage -2007.
The CSS takes the Greenwich time (reference) each second transmitted by the satellite Global Positioning System (GPS). The reference time is converted by the "Vulcan-CIS/SPDS-2" Distributed Computer System (DCS) into the local winter/summer time of Ukraine (second time zone). The BPKV-M device installed on the "Vulcan-CIS/SPDS-2" (DCS) workstation generates the encoded reference time signal for the NPP Unit I&C systems. The fiber-optic communication lines, using the passive twisted pair/FO converters, provides transmission of the reference time signals from the CIS room to the I&C rooms.
More Digital Data Links for South-Ukraine NPP Unit 2 CIS
July 20, 2007
The upgrades of the Safety Systems, AZ-PZ (Reactor Emergency Protection and Reactor Preventive Protection) and ARM-ROM (Automatic Reactor Power Controller and Reactor Power Reducing Device) have caused implementation of the SUNPP Unit 2 CIS digital data links with the following SUNPP Unit 2 I&C systems during the SUNPP Unit 2 outage-2007:
Safety System 1st, 2nd, and 3rd Trains
1st and 2nd AZ-PZ kits
ARM-ROM
Primary automatic regulators
Secondary automatic regulators (Turbine Control System)
Feedwater Flow and Steam Generator Level Control System (FWCS)
For the implementation of the SUNPP Unit 2 CIS digital data links with the above SUNPP Unit 2 I&C systems, Westron has supplied the "Vulcan-CIS/SPDS-2" Distributed Computer System hardware, the network hardware, and the software. The implementation of the above SUNPP Unit 2 CIS digital data links has been provided using the documentation developed by Westron.
Armenia NPP Unit 2 Diesel Generator
Load Sequencer "Vulcan-M-DGLS" DCS FAT
July 24, 2007
FAT of two "Vulcan-M-DGLS" Digital Control Systems (DCS) for Armenia NPP Unit 2 Diesel Generator Load Sequencer (DGLS) has been successfully completed at Westron.
Class 1 E "Vulcan-M-DGLS" DCS are designed for auto control of consumers connection to diesel generators for NPP Unit power supply in case of emergency Unit power supply loss.
"Vulcan-M-DGLS" DCS are based on the "Vulcan-M" hardware designed and manufactured by Westron. Each "Vulcan-M-DGLS" DCS is provided with three channels where two of three voting logic is used.
The "Vulcan-M-DGLS" DCS software developed by Westron is based on the initial data provided by NiAEP (Nizhni Novgorod, the Russian Federation) and Armenia NPP.
The "Vulcan-M-DGLS" DCS implementation is planning during Armenia NPP Unit 2 outage-2007.
