Synopsis:

Critical experiment is a semestral project focused on designing a new core configuration, its assembling and verification at the VR-1 reactor. Within the course the students will be familiar with the safety, operational and legislative requirements place on the critical experiment. Under the supervision of the lecturer, the students prepare a new core configuration at the VR-1, they perform its computational verification and prepare the relevant documentation required by SÚJB. The main practical part of the course will be focused on the realization of the critical experiment. Students will assemble and experimentally verify new core configuration at the VR-1 reactor. They have also to process all data from experiment, evaluate them and produce detailed document informing about the results of the experiment.
