Certain problems associated with the design and construction of and the results of work performed on large-scale safety test stands for water-moderated water-cooled, channel, and boiling-water vessel reactors are presented. It is shown that inadequate adherence to simulation principles in experimental setups can result in incorrect results concerning the effectiveness of emergency core-cooling systems in reactors. The results obtained in this country and abroad show that a successful design, technological effectiveness, and reliability of all components of the model of a reactor core prevent the loss of time and resources in performing experimental programs. For example, such losses resulting from frequent failures of fuel element simulators, which are technologically highly effective and critical components of test stands, can be eliminated. |
