What is Reactor Pressure Vessel - Definition

What is Reactor Pressure Vessel - Definition

The reactor pressure vessel is the pressure vessel containing the reactor core and other key reactor internals. Most of commercial power reactors are light water reactors ( PWRs and BWRs ), which are cooled and moderated by high-pressure liquid water (e.g. 16MPa in case of PWRs) and therefore the reactor vessel must withstand high pressures.

corrosion damage. Operators of all 69 U.S. pressurized water nuclear power reactors were notified in March to look for damage to their reactor vessels, but not specifically for boric acid deposits. So far, no similar corrosion damage has been found at other nuclear plants. If the reactor vessel had been breached by the acid, the NRC and

Coal has been mined and used as a source of energy for centuries. The first recorded use of coal was in China, with indications that the Chinese began using coal for heating and smelting about 2500 years ago, and most historians believe that coal was used in various parts of the world 3000–4000 years ago during the Bronze Age [].A system for mining coal was present in England by 1180 [].
