Conceptual Design of the Safety System for a SCWR Fuel Qualification Test
The test of a small scale fuel assembly operated with supercritical water in a critical arrangement is planned to be performed in the LVR-15 reactor of the Research Centre Rez (UJV), Czech Republic. It shall include 4 fuel rods of 60cm length inside a pressure tube to be operated at 25 Mpa pressure at the peak power conditions of the European High Performance Light Water Reactor concept. The test section is connected with a closed supercritical water loop at 300℃, and a recuperator is increasing the coolant temperature at the test section inlet to hot channel conditions of the evaporator of the above mentioned reactor. This paper describes the safety system needed to run the supercritical water loop. Like a boiling water reactor, it includes a depressurization system, a low pressure coolant injection system and an emergency coolant injection system to remove the residual heat safely in case of accidents. Numerical simulations with the system code APROS have been performed to check the system performance in case of a loss of coolant accident, a pump trip and a coolant bypass. The fuel section is expected to remain sufficiently cooled during any of these accident scenarios.
