High-temperature gas-cooled reactor steam-cycle/cogeneration lead plant reactor system design description
The primary functions of the Reactor System are to generate heat from fission energy, to transfer that heat to the primary coolant, and to control the coolant flow distribution and neutron generation rate in the core. The Reactor System also provides shielding for the Reactor Vessel. The most important safety function is to constitute the first barrier to fission product release. This function is performed jointly by the coated fuel particles and the graphite of the fuel elements. The system also assures adequate control of the neutron generation rate under all postulated plant conditions. The Reactor System consists of the graphite moderated reactor core and its associated supports, controls, and instrumentation and is primarily located inside the pressure boundary of the Reactor Vessel, either in the core cavity or in the adjoining top head penetrations. The installation of the inital core is included in the scope of the system.
