A reactor vessel head for a pressurized water reactor. This structure is attached to the top of the reactor vessel body. It contains penetrations to allow the control rod driving mechanism to attach to the control rods in the fuel assembly. The coolant level measurement probe also enters the vessel through the reactor vessel head.

English: Nuclear reactor: pressurized water type. Water is heated through the splitting of uranium atoms in the reactor core. The water, held under high pressure to keep it from boiling, produces steam by transferring heat to a secondary source of water. The steam is used to generate electricity.
The aim of the template is to show the characteristics of an reactor design (e.g. RBMK) or individual experimental or prototype reactors (e.g. Chicago Pile-1 or Superphénix), but not for individual power plants (e.g. not Chernobyl Nuclear Power Plant)
These heads have a dish with a fixed radius (r1), the size of which depends on the type of torispherical head. [3] The transition between the cylinder and the dish is called the knuckle. The knuckle has a toroidal shape. The most common types of torispherical heads are:
- A pressurised heavy water reactor is a nuclear power reactor that uses unenriched natural uranium as nuclear fuel and heavy water as moderator and as primary coolant. The heavy water is kept under pressure in order to raise its boiling point, allowing it to be heated to higher temperatures and thereby carry more heat out of the reactor core.
Schematic diagram of an RBMK Schematic side view of the layout of an RBMK reactor core The reactor hall and piping systems of the RBMK reactor. The reactor pit or vault is made of reinforced concrete and has dimensions 21.6 m × 21.6 m × 25.5 m. It houses the vessel of the reactor, which is annular, made of an inner and outer cylindrical wall ...
