540 ° C under thermal cycling conditions with a span of 250 ° C for 500 hours. In situ studies of the heat exchanger of the BN-type reactor confirmed the efficiency of the developed methodology and allowed obtaining data on the stresses occurring in the structure. The experience of the conducted research allowed proposing a methodology for determining the SSS of the internal surfaces of BN reactor equipment based on the results of indirect measurements.
