At the end of May 2018, the acceptance testing of the instrumentation and control systems of the instrumentation and current distributors (I&C of KIP-RT) and the automatic regulating system (I&C of SAR) of the reactor division normal operation system (NOS RO) for unit 4 and the equipment of special building 1 of Zaporizhzhya NPP was carried out at the site of PJSC “SRPA “Impulse”, the systems were created within the framework of implementation of the “Complex (Consolidated) Safety Upgrade Program for NPP Units” project using credit funds of EBRD/EURATOM.
I&C of KIP-RT of NOS RO and I&C of SAR of NOS RO are designated to implement functions of receipt, normalization, and processing of input signals from primary measuring transducers, to shape output current and discrete signals, to execute automatic control functions, to receive information on state of technological process parameters with transmission to the unit’s computer information system.
The equipment of special building 1 is designated to execute a visual displaying function for information on monitored parameters.
The aim of the acceptance testing of I&C of KIP-RT of NOS RO, I&C of SAR of NOS RO and the equipment of special building 1 was as follows: confirmation of meeting the requirements of the terms of reference, the design documentation, and the normative documents.
Based on the results of the acceptance testing, the commission consisting of representatives of ZNPP, State Scientific and Technical Center for Nuclear and Radiation Safety, and PJSC “SRPA “Impulse” stated that I&C of KIP-RT of NOS RO, I&C of SAR of NOS RO and the equipment of special building 1 submitted for the testing meet the NRS norms, rules and standards, the requirements of the terms of reference completely and are ready to be supplied to unit 4 of Zaporizhzhya NPP.
