The primary containment structure is made of steel 1 inch thick; The secondary containment structure is made of steel-reinforced, pre-stressed concrete 1.2–2.4 meters (3.9–7.9 ft) thick. The reactor building (the shield wall/missile shield) is also made of steel-reinforced, pre-stressed concrete 0.3 to 1 m (0.98 to 3.28 ft) thick.
The primary containment consists of "drywell" and "wetwell" concrete structures below the top level, immediately surrounding the reactor pressure vessel. The secondary containment includes the top floor with water-filled pools for storing fresh or irradiated fuel and for storage of irradiated tools and structures. [26] [50]
Secondary spill containment is the containment of hazardous liquids in order to prevent pollution of soil and water. Common techniques include the use of spill berms to contain oil -filled equipment, fuel tanks , truck washing decks, or any other places or items that may leak hazardous liquids.
This similarity is limited to appearance. Like other BWRs, the actual containment vessel for the reactor is a separate drywell/torus structure enclosed within the reactor building, but structurally separate. The outer reactor building serves as secondary containment and houses many of the reactor's safety systems.
The typical profile of a vessel with secondary containment is a primary vessel with an exterior vessel shell encompassing the primary vessel with at least 100% capacity. Secondary vessels are available in polyethylene, fiberglass and metal materials. Secondary containment tank systems are suggested for all aggressive chemicals.
Computer generated view of an EPR power station Reactor pressure vessel of the EPR. The EPR is a Generation III+ pressurised water reactor design. It has been designed and developed mainly by Framatome (part of Areva between 2001 and 2017) and Électricité de France (EDF) in France, and by Siemens in Germany. [1]
