What is Reactor Pressure Vessel ?

A pressure vessel is a container for containing liquids or gases at a pressure which is substantially different from ambient pressure.

The pressure difference is dangerous, and there are fatal accidents in the history of pressure vessel development and operation have occurred. As a result, are the design of pressure vessels, manufacture and operation by the supported by regulated engineer regulatory authorities. For these reasons, the definition of a pressure vessel of a country varies but includes parameters such as maximum working pressure for safety and temperature and is equipped with a safety factor, accuracy at Corrosion, minimum temperature (for fragile fractures) and worked destructive tests such as ultrasonic testing, radiography and compression, usually with water, also known as hydraulic testing, but could be tested with Air or other gas. The preferred test is the hydrostatic test because it is much safer test method because it releases much less energy when the break occurs (water does not increase rapidly in volume, while depressurization Fast occurs, as opposed to gases such as air, that is, no explosive gas).

In the United States, as in many other countries, it is the law that ships on a certain size and pressure (15 PSI) to build to the code in the US code is the ASME on boilers and Vessel Pressure Code BPVC) These vessels also require an authorized inspector to build on each new vessel and each vessel has a name tag with relevant information about the vessel that the maximum permissible working pressure, maximum temperature, design metal temperature Date, its registration number (by the National Office) and the ASME official stamp for pressure vessel (U-buffer), so that the traceability of the vessels and officially code ship ASME.
