摘要： A pressurized water reactor (PWR) includes a pressure vessel containing a nuclear reactor core immersed in primary coolant water, control rod assemblies (CRA's), and control rod drive mechanisms (CRDM's) operating the CRA's. The reactor core has axially varying 235U enrichment and/or axially varying burnable poison concentration. A CRDM controller controls the CRA's over a burn-up cycle that does not include fuel assembly shuffling and is divided into a plurality of burn-up intervals. The CRDM controller is configured to, for each burn up interval: position the CRA's in accordance with a CRA pattern defining a set of fixed positions for the CRA's except for a sub-set of CRA's designated by the CRA pattern as floating CRA's, and control power level of the PWR by adjusting the floating CRA's without not adjusting the CRA's not designated as floating CRA's. The primary coolant water optionally does not contain soluble neutron poison.

摘要： The core flow rate of a boiling water reactor (BWR) (19) is adjusted so that it reaches a core flow rate setting that is determined from the characteristic according to the ratio of Pu-239 in transuranic nuclides (TRU) included in a new fuel assembly (1) to be loaded in a core (20). The core flow rate is maintained at the set core flow rate in all operation cycles of the BWR (19). Accordingly, the ratios of a plurality of TRU isotopes included in a fuel assembly (1) when the fuel assembly (1) is taken out of the BWR core (20) as a spent fuel is substantially the same as the ratios of the plurality of TRU isotopes included in a new fuel assembly (1) to be loaded in the BWR core (20). The ratio of Pu-239 in TRU included in the new fuel assembly (1) is 3% or more but 45% or less. As a result, a nuclear proliferation resistance can be increased while restrictive conditions for safety are met, a burnup can be further increased, and TRU multi-recycling becomes feasible.

摘要： A nuclear reactor is provided with a core which includes a new fuel part and a burning part at which neutrons are generated and fuel is burned. The burning part moves in a direction toward the new fuel part from the beginning to the end of the combustion cycle. The plurality of the fuel assemblies of the core include the fuel assemblies which are fastened to the core and the fuel assemblies which can move in the longitudinal direction of the fuel assemblies. By pulling out the fuel assemblies from the core, the nuclear reactor can be made to stop. Further, by inserting fuel assemblies into the core from the pulled out state, the nuclear reactor is started up.
