The paper deals with the results of in-service testing conducted by acoustic emission method of 103-D type reactor, applied in ammonia production, It is shown that areas with defect concentration have formed in the vessel by the moment of testing. It is noted that furtheron these areas can accumulate propagating defects, which will present a certain hazard, classified by the scale of predictive algorithm of the testing equipment. In view of that continuous monitoring and periodical evaluation of residual life are recommended for such structures. 12 References, 1 Table, 9 Figures.
 
Keywords: acoustic emission, 103-D reactor, propagating defects, continuous monitoring, residual life
