Method of operating a gas cooled graphite moderated - nuclear reactor

摘要

Method of operating a gas cooled graphite moderate nuclear reactor. G6C. The quantity of fuel removed and exchanged when the reactor is being reloaded corresponds to the period of full useful life of the fuel and the coolant flow through each channel in the core is set to correspond to a limit criterion for the channel during the operating period between one fuel change until the next. Fuel changes are made with the reactor out of service and the coolant gas pressure above atmospheric pressure. Coolant flow rates may be set manually by reactor personnel and they may be remotely controlled from outside the reactor. Partial fuel exchange in a homogeneous reactor involves changing a number of fuel sections, each of which also includes moderator material.
