Research reactor and auxiliary technologies for the Institute of Nuclear Research "Řež"
LVR - 15
Delivery for the most important European research reactor
The LVR-15 reactor, operated at the Řež Research Center, is one of the most important European research reactors. In the second half of 2015, the reactor protection and control system (SOŘ) was renewed and the reactor power regulator was replaced by our company ZAT.
As part of the project, we replaced the original protection and control system from the late 1980s. We developed, installed and tested a completely new system for the Řež Research Center, including neutron flux measurement devices. This product has became the basis for a similar power regulator for large energy pressurized water reactors.
The purpose of the protection and control system is several seemingly simple activities from starting the reactor, through changing the power during operation and standard shutdown to supervising their safety. The system provides the operator with the information necessary to control the reactor and at the same time automatically evaluates the technological quantities. For example, if the rate of change of power exceeded the specified values, the SOŘ would immediately shut down the reactor safely. The emergency chain falls into safety category A according to ČSN EN 61226 and is solved in the form of a relay with high reliability.
We increase safety and reliability
At the LVR-15 Research Reactor, ZAT engineers performed a complete overhaul of the protection and control system. It involves the replacement of neutron instrumentation, emergency chain, control system, reactor power regulator, control and signaling elements on the operator's desk, power converters for controlling control rods and control rod drive motors.
The position control system of the control rods itself is technically unique because it is very closely linked to a specific technology - in addition, the sensing and drive elements are located directly inside the reactor.
Thanks to the project for the Řež Research Center, we have expanded our product range with a power regulator. The new SandRA control system from ZAT has increased the safety and reliability of the Rector's operation and made it possible to extend its operation until at least 2028.
History of cooperation with the Institute of Nuclear Research "Řež"
2014 - 2015
In the second half of 2015, the renewal of the reactor protection and control system was completed
The innovative project on the SandRA platform for the LVR-15 research nuclear reactor won an award from the Academy of Engineering of the Czech Republic
We followed up on the successful implementation of LVR-15 and to ensure the safe operation of the experimental equipment of the Hot Chamber - SUSEN in the Řež Research Center (CVŘ). By participating in the SUSEN project, we are thus contributing to the development of the transition to new-generation nuclear reactors, ie. GIII + and GIV
