Rovno NPP Unit 4 Radiation Monitoring System Upgrade

December 10, 2007

“Vulcan-RM4” Radiation Monitoring System (RMS) SAT has been successfully completed at Rovno NPP Unit 4.

The "Vulcan-RM4" RMS Upper Level and safety systems measuring channels were put into operation in 2004 prior the Rovno NPP Unit 4 startup. In 2007 the AKRB-03 complete replacement, integration of the auxiliary measuring facilities into the system and implementation of the system auxiliary functions have been provided. The similar "Vulcan-RM3" RMS for Rovno NPP Unit 3 has been put into operation in 2007.

The RMS of the new generation has been designed and manufactured by Westron. The main Westron’s subcontractor is Positron enterprise. “Vulcan-RM” RMS has been designed for the replacement of the obsolete NPP RMS systems (AKRB-03, AKRB–06 and AKRB-08), extension of the RMS scope, improvement of radiation monitoring automation, reliability and validity. “Vulcan-RM” RMS completely meets the requirements applicable for VVER and RBMK NPP RMS systems. There are capabilities for phase-by-phase replacement of the operational RMS by the “Vulcan-RM” RMS.

The RMS upgrade based on “Vulcan-RM” RMS is also performed on Zaporozye NPP, Rovno NPP and South-Ukraine NPP.
