摘要： PROBLEM TO BE SOLVED: To provide a boiling water reactor free from damaging a steam drier or the like in a reactor pressure vessel by suppressing effectively pressure vibration generated in a main steam system without reducing reactor heat output. SOLUTION: Pressure sensors 17, 18 always detect a fluctuating pressure following acoustic resonance generated inside a steam dome 7 and a steam pipe 8. A monitoring/control device 19 controls a bleeding amount supplied from a high-pressure turbine 9 to a feed water heater 13 by controlling opening of a bleeding valve 14, based on the level of the fluctuating pressure detected by the pressure sensors 17, 18, and controls fission energy from an uranium fuel in a core shroud 2 by controlling control rods 16 through a control rod driving device 15. Hereby, since the steam quantity generated in the reactor pressure vessel 1 is decreased, a steam flow passing the main steam system is reduced and the pressure vibration based on the acoustic resonance is suppressed. Since the enthalpy difference between feed water 3 and steam 4 in the input/output of the reactor pressure vessel 1 is increased, the reactor heat output is maintained constant.

摘要翻译：要解决的问题：通过在有效地抑制主蒸汽系统中产生的压力振动而不减少反应堆热量输出的同时，提供一种在反应堆压力容器内不会损坏蒸汽干燥器等的沸水反应器。解决方案：压力传感器17,18总是检测在蒸汽穹顶7和蒸汽管8内产生的声共振之后的波动压力。监视/控制装置19控制从高压涡轮9供应到基于由压力传感器17,18检测到的波动压力的水平，通过控制排出阀14的打开来控制进料热水器13，并通过控制控制棒16控制核心护罩2中的铀燃料的裂变能量因此，由于在反应堆压力容器1中产生的蒸汽量减少，所以通过主蒸汽系统的蒸汽流减少，并且基于声共振的压力振动被抑制。由于反应堆压力容器1的输入/输出中的给水3和蒸汽4之间的焓差增加，反应堆的热量输出保持恒定。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To suppress pressure vibration accompanying acoustic resonance occurring in a main steam system of a boiling water reactor.
SOLUTION: Pressure sensors 13 and 14 are disposed in a steam dome 6 and a steam pipe 9, and pressure vibration amplitude is detected. The steam dome 6 or steam pipe 9 is provided with a Helmholtz resonance tube 12, and an opening regulating valve 11 is mounted to an inlet pipe 121. The opening of the opening regulating valve 11 is regulated in the direction of decreasing the detected pressure vibration amplitude. Thus, when the detected pressure vibration amplitude becomes minimum, the resonance frequency of the Helmholtz resonance tube 12 matches with (is close to) resonance vibration frequency of the steam system, and can effectively suppress the pressure vibration due to the acoustic resonance.

摘要： PROBLEM TO BE SOLVED: To provide a fuel spraying device of an internal combustion engine capable of achieving high combustion efficiency of the internal combustion engine by atomizing fuel stably.
SOLUTION: The fuel is atomized in a very fine particle 10 state by atomizing fuel entering from the direction of an arrow 2 from an exhaust nozzle 4 of a nozzle as a filamentous jet stream 7 and colliding the fuel jetted from the nozzle with an inclined plane of a target 8 by the energy of the filamentous jet stream 7. Because the inclined plane of the target 8 is flat, the atomized very fine particle 10 is sprayed without hitting the target again. Furthermore, because a gap space 11 for flowing the outside air of spraying out periphery exists at the spraying center position between the targets, the cone collapse phenomenon of the spraying distribution shape can be evaded. Accordingly, the enlargement by the reaggregation of the very fine particle 10 after the fuel is atomized and the spraying shape transformations can be suppressed. Therefore, the combustion efficiency of the internal combustion engine by the optimum fuel spraying can be improved.

摘要翻译：要解决的问题：提供能够稳定地雾化燃料而能够实现内燃机的高燃烧效率的内燃机的燃料喷射装置。解决方案：通过从喷嘴的排气喷嘴4将从箭头2的方向入射的燃料作为丝状喷射流7将燃料雾化成非常细的颗粒10状态，并将从喷嘴喷射的燃料与倾斜平面碰撞由于目标8的倾斜平面是平坦的，所以雾化的非常细的颗粒10被喷射而不会再次撞击目标物。此外，由于在喷射中心位置之间存在用于使喷射外围的外部空气流动的间隙空间11，因此可以避免喷射分布形状的锥形崩溃现象。因此，可以抑制燃料雾化后的极细颗粒10的再聚集和喷雾形状转变的扩大。因此，可以提高通过最佳燃料喷射的内燃机的燃烧效率。

SOLUTION: A throttle part 35 is arranged on a transition piece inner cylinder 32. Most of a pressure wave 39 incident from a combustion chamber 7 is reflected by a compression flow passage 34, a pressure wave incident to a spot situated downstream from the throttle part 35 is reduced to extremely a part thereof and most of a reflection pressure wave returning to the combustion chamber 7 forms a pressure wave irregularly reflected by the compression flow passage 34. Thus, any specified resonating wavelength is not present and combustion vibration is hardly generated.
