摘要： Apparatus (10) for monitoring the neutron flux generated by the core (3) of a nuclear reactor (1), the core (3) of which is enclosed in a pressure vessel (2) which delimits the nuclear reactor (1), includes a plurality of solid-state detector elements (4) for detecting nuclear emissions arranged outside the vessel (2) and is able, at limited expense, to map the data from a large number of points at the same time while occupying a limited space.

摘要： A beta ray flux measuring device 30 in an activated member in-core instrumentation system 2 for pressurized water reactors 10. The device includes collector rings 110 positioned about an axis 80 in the reactor's pressure boundary 120. Activated members 85 such as hydroballs 90, 165 are positioned within respective ones of the collector rings 110. A response characteristic such as the current from or charge on a collector ring 110 indicates the beta ray flux from the corresponding hydroball 90, 165 and is therefore a measure of the relative nuclear power level in the region of the reactor core 20 corresponding to the specific exposed hydroball 90, 165 within the collector ring 110.

摘要： A radiation shielding method and a device, and a method of processing a structure, in which a first radiation-shielded region (A1) is provided by disposing a first radiation-shielding device (100) outside a nuclear reactor vessel (41), a neutron flux detector (77) is moved into the radiation-shielded region (A1) through a conduit tube (65) by moving a thimble tube (68) from the nuclear reactor vessel (41), and an inspection/repair work of the nuclear reactor vessel (41) is then performed, so that an amount of radiation delivered to a worker can be easily and sufficiently reduced.
