【 摘 要 】

The method of experimental and calculation determination of a stressed state in the NPP cases coolant input units in the conditions of rapid temperature changes is considered. A monitoring algorithm using strain gauge control and an algorithm based on solving direct and inverse problems of experimental mechanics is proposed.
