THE ACCEPTANCE TESTING OF THE ESFAS-1 I&C SYSTEM INSTRUMENTATION AND CONTROL SYSTEM OF THE SAFETY CONTROL SYSTEM FOR UNIT 2 OF KHMELNITSKY NPP HAS BEEN CARRIED OUT

In November 2021, the acceptance testing of the instrumentation and control system of the safety control system of the safety control system (ESFAS-1 I&C system) for Unit 2 of Khmelnitsky NPP was carried out at the site of PJSC “SRPA “Impulse”.

The ESFAS I&C system is designated to initiate actuation of safety systems, to monitor and control them in the process of execution of the given functions. The ESFAS I&C system assures implementation of the safety control function and the normal operation functions in the scope of the existing design of one channel of the safety control system (including technological protections, interlockings, signalling, automatic regulation, remote control of actuators of the corresponding channel of the safety system), receipt of information on the state of the parameters of the technological processes with transmission to the unit’s process information system (IVS).

The aim of the acceptance testing of the ESFAS-1 I&C system for KhNPP-2 was as follows: to confirm the compliance of the supply set of the equipment of the ESFAS I&C system for Unit 2 of SS KhNPP with the requirements of the terms of reference, the design and normative documentation.

Based on the results of the acceptance testing, the commission consisting of representatives of Skoda JS a.s., Khmelnitsky NPP, State Scientific and Technical Center for Nuclear and Radiation Safety, and PJSC “SRPA “Impulse” stated that the testing was performed in accordance with the plan and the methodology for the given testing and the testing results confirm that the ESFAS I&C system meets the requirements of the terms of reference and the normative documentation. The design, operational, and program documentation for the ESFAS I&C system meets the requirements of the terms of reference, and the equipment is ready to be supplied to Unit 2 of Khmelnitsky NPP.
