	This paper presents the technical condition assessment of a RC digestion dome chamber after fourteen years of exploitation. The authors conducted experimental investigations, i.e. tests of concrete compressive strength using a scleroscope, concrete chemical analysis in the laboratory and detections of reinforcement. On the basis of the obtained results and cracks morphology, static-strength calculations were conducted. The results of the FEM numerical analysis indicated deficiencies in the bearing capacity of the dome. The widths of the calculated cracks exceeded allowable values. The authors proposed two alternative methods of chamber strengthening: pouring additional RC dome cover or post-tensioning the dome with external unbonded tendons.
