Reactors, Cores & Reactor Vessels Function Design and Flow .

Reactors, Cores & Reactor Vessels Function Regardless of type, a nuclear reactor has 3 major functions: to produce the heat and transfer that heat to the coolant, to maintain a pressure boundary (so the coolant is not lost), and to provide a structure to hold the fuel. The reactor is being treated separately from the reactor coolant system.

The reactor coolant pressure boundary, in particular the reactor pressure vessel and the reactor coolant piping, provide independent barriers to prevent the release of radiation.

Reactor pressure vessel - Wikipedia

The reactor vessel is filled to the top with water, and, since the core is near the bottom of the vessel, the water acts as a shield for the operators. Each fuel assembly to be removed is grasped by a fuel-handling tool and then lifted from its position in the core into a shielded cask, within which the assembly is transferred to a storage pool .
