摘要： PROBLEM TO BE SOLVED: To properly cope with a minor rupture accident and improve the safety and economic property of a nuclear reactor by injecting water into a reactor vessel by a steam injector. SOLUTION: When a minor rupture accident occurs, an automatic pressure reducing system 5 or an isolation condenser is operated to reduce the internal pressure of a reactor pressure vessel 2. When the internal pressure of the vessel 2 is lowered to a prescribed value, a low pressure core water injecting system 16 is operated. After several minutes from operation start, combining water from a steam injector 17 is injected into the vessel 2. The internal pressure of the vessel 2 is lowered by water injection of the water injecting system 16, and when the downstream side pressure of a check valve 14 becomes lower than the head pressure of a pool 11, the valve 14 is opened to inject water in the pool 1 into the vessel 2 through a piping 12. Just after the occurrence of the minor rupture accident, the level in the vessel is recovered and kept by water injection of the water injecting systems 16, 10 to ensure the cooling of a core 3. The steam in the vessel 2 is released into the dry well DW of a reactor container 1 to ensure a long-term cooling.

摘要： PURPOSE:To provide a system by which the best tomographic image can be obtained always even if X-ray source energy is switched according to a specimen by arranging a switching mechanism to switch simultaneously a main filter and a filter for a comparator-detector. CONSTITUTION:An X-ray from an X-ray source 1 is radiated to a specimen 13 as an X-ray fan beam 3 through a collimator 2, a filter switching mechanism 8 and a collimator 5. The X-ray passing through the specimen 13 is detected by a main detector 7 through a collimator 6. As for the X ray from the X-ray source 1, an X-ray beam 4 for a comparator-detector is taken out and is made incident on the comparator-detector 9 besides being formed as the X-ray fan beam by the collimator 2. A switching mechanism 8 switches simultaneously a main filter and a filter for the comparator-detector inserted in respective passages of the X-ray fan beam 3 and the X-ray beam 4 for the comparator- detector according to switching of tube voltage of the X-ray source 1, or shields the X-ray from the X-ray source 1.

CONSTITUTION:A reactor state visualization system consists of a reactor characteristic analysis part 13, a neutron dynamic characteristic analysis part 15, a memory 17, an animation display 21 and the like. The analysis part 13 is allowed to analyze a dynamic characteristic on thermohydraulic behavior of a reactor pressure vessel on the basis of a measured value signal or an operation signal and evaluate a reactor state in a real time. The analysis part 15 is allowed to substitute a dynamic characteristic value on the thermohydraulic behavior analyzed in the analysis part 13 for a neutron dynamic characteristic equation to find reactivity so as to calculate the level of a neutron flux in a real time. The memory 17 is allowed to store a transient change of the thermohydraulic behavior dynamic characteristic analyzed in the analysis part 13 in a time series. The animation operation part 19 is allowed to animate the thermohydraulic behavior stored in the memory 17. Its result is displayed in the display 21.

摘要： PURPOSE:To suppress the misalignment quantity between each of a radiation generator and a radiation detector to the minimum and to measure the plate thickness with high accuracy by bringing a first and a second frames to rigid junction to a vertical frame and forming a U-shaped frame. CONSTITUTION:A U-shaped frame 4 is formed by bringing a first frame 2 and a second frame 3 to rigid junction to a vertical frame 1. Also, a radiation generator 8 is supported by a first supporting material 5 whose thermal expansion coefficient is lower than that of the frame 2, and the supporting material 5 is provided in parallel to the frame 2 by fixing its one end to the frame 1, and also, constrained to the frame 2 so as to be expandable and contractable only in the other end direction. Moreover, a radiation detector 14 corresponding to the generator 8 is supported by a second supporting material 11 whose thermal expansion coefficient is the same as that of the supporting material 5. In this state, even if a temperature difference is generated between the frames 2, 3 and a difference is generated in the thermal expansion and contraction quantum between both the frames, the thermal expansion and contraction quantity between the supporting materials 5, 11 whose thermal expansion coefficient is lower than that of the frames 2, 3 is suppressed to the minimum. Accordingly, the misalignment quantity between each of the generator 8 and the detector 14 is suppressed to the minimum within a range of the allowable quantum and the plate thickness is measured with high accuracy.
