ACCEPTANCE TESTS OF AUTOMATIC TURBINE REGULATING AND PROTECTION SYSTEM EQUIPMENT FOR RNPP UNIT 4 ARE CONDUCTED

In November 2024 at the test site of SRPA “Impulse” the successful acceptance tests of equipment designed to modify electrohydraulic and electronic parts of the automatic regulating and protection system for the К-1000-60/3000 turbine of RNPP Unit 4 (SARZT) were conducted.

SARZT regulates automatically frequency and power of the turbine in the both normal and emergency operation modes of the Unit and the energy system. When operating simultaneously as a part of the entire Ukrainian energy system it provides for normalized primary regulating of frequency and power.

SARZT is realized based on MSKU 4 industrial controllers and PS5140 workstations.

As a result of work the acceptance commission consisting of the representatives of Rivne NPP, SSTS NRS and SPRA “Impulse” concluded:

• The equipment presented meets the requirements of Terms of reference, effective regulations, rules and standards on nuclear and radiation safety including the requirement regarding cyber security;
• Designing, technical, and operating documentation as well as software documentation meet the requirements of TOR and are sufficient for its application;
• To declare that the SARZT equipment is ready to be supplied to the RNPP Unit 4.
