Beschreibung
Zusammenfassung:	A method is disclosed herein for detecting cracks of a fluid storage tank due to breakage of a wall of the fluid storage tank. In an example embodiment, the method includes positioning an enclosed pressure-resistant jacket around an outer wall of the fluid storage tank, controlling a temperature of the fluid in the fluid storage tank by allowing a liquid cooling or heating medium to flow in the enclosed pressure-resistant jacket at a pressure lower than a pressure x applied within the fluid storage tank, maintaining the pressure in the pressure-resistant jacket lower than the pressure x, sampling the cooling or heating medium from an air pool provided in a passage of the cooling or heating medium, and analyzing components of the cooling or heating medium, while preventing contamination of the fluid in the fluid storage tank with the liquid cooling or heating medium.
