Abstract
Some features of the core loading formation for the MIR.M1 research reactor during preparation of experiments to study the behavior of fuel rods for water-cooled reactors in accidents with loss of a coolant are discussed. The main structural and physical features of the reactor, as well as main directions of its use, are briefly presented. It has been shown that the preparation of the same type of experiments with the same initial requirements to ensure the test conditions in the MIR.M1 reactor core is a difficult task, depending on the initial conditions for loading the working and loop channels, poisoning of beryllium blocks of the core. For successful implementation of experiments, it is necessary to take into account numerous factors associated with both structural and operational features of the reactor. In this case, the final state of the reactor at the beginning of the experiment and upon reaching the target parameters of the test rig in a loop channel can be completely different. It has been shown that described approaches to the reactor core loading formation make it possible to safely conduct complex dynamic experiments simulating the emergency operation of the tested nuclear fuel rods. Some results of these experiments important for the discussed problem have been presented.
