Tank leakage

Low-temperatiire liquefied gases are shipped in special ships with insulation between the niiU ana an inner tank. Poisonous materials are shipped in separate tanks built into the ship. This prevents tank leakage from contaminating harbors. Separate tanks are also used to transport pressurized gases. 

It should be noted that these can also be caused by other problems besides tank leakage, such as leaking valves, loose fittings, or other factors. 

Another method to examine tank leakage uses instrumentation. An instrumental test should be conducted if there is the suggestion of a leakage from various environmental or mechanical indicators or from an inventory review. 

Means for Preventing Tank Leakage. In addition to the common sense approaches, such as selecting corrosion, weather, and moisture-resistant materials of construction, providing excellent foundations, and leak-detection instrumentation, there are additional preventive measures that can be taken. Cathodic protection, for example, is described in an article on Corrosion.

Risk Assessment 5 4D (see Tables 2.1—2.3). The probability of tank leakage might be assessed as remote, especially if X-ray analysis of welded seams is performed prior to installation. Even if it were to leak, the resulting severity would be considered negligible (i.e., less than minor injury, occupational illness, or system damage) since the liquid would be contained in the concrete pit area. Therefore, the risk assessment matrix recommends that such a risk be classified as acceptable, without review. 

The Shutdown Cooling System (SCS) is a closed system without an accumulator (tank). Leakage from the RCS to SCS under normal operation, when the system is isolated from the RCS, would be detected by SCS pressure, and alarmed at a pressure less than the design pressure. If design pressure is reached the safety valves will open and the water will flow to the Equipment Drain Tank (EDT), where the change in level will be utilized to quantify the leak.
