摘要： PROBLEM TO BE SOLVED: To solve a problem wherein a conventional device for preventing overflow stream of a fuel storage pool inhibits visibility and workability in a pool.
SOLUTION: A plurality of rails 1 are disposed at constant intervals on a sidewall 11 of a fuel storage pool 10, and overflow preventing plates 2 formed of a ponding plate 3 and a float 4 are arranged between the plurality of rails 1, thereby forming this overflow prevention device 60. A part of the float 4 is above the water surface. When water level is raised locally by sloshing, the float 4 above the water surface goes under the water, the buoyancy of the overflow preventing plates 2 increases, and the overflow preventing plates project upwardly slidably along the rails 1 and function as a dam for preventing the overflow.

摘要： PROBLEM TO BE SOLVED: To provide a damage estimating method for an earthquake damage predicting system which estimates the earthquake damage or influences in a limited area, such as small regions in a short time from observed information of an observing means installed in the area, without using an analysis model. SOLUTION: Observed earthquake data are filtered so that only frequency bands (natural frequency bands) influencing the response of a structure remain, thereby estimating the damage conditions from a maximum value thereof. An input energy is evaluated to estimate the damage of the structure. The change of oscillation characteristics of the structure under consideration is taken during earthquake to estimate the damage. Thus, the damage to the structure can be estimated quickly without using an analysis model of the structure. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To solve the problem that an inside annular rubber plate 16 of a vertical seismic isolation part 18 suffers from early-stage damage because deformation of the rubber plate 16 is larger than that of an outside rubber plate 16. SOLUTION: The length of the outside annular rubber plate 16 of the vertical seismic isolation part 18 is configured to be shorter than that of the inside annular rubber plate 16, and the amounts of deformation of the outside annular rubber plate 16 and the inside annular rubber plate 16 are set to be the same order when the vertical seismic isolation part 18 receives vertical deformation, thereby the early stage damage to a partial section thereof is prevented and the reliability of a seismic isolator is raised.

摘要： PURPOSE:To reduce the earthquake response of a reactor core and an inter-dry well piping system by varying the rigidity of a stabilizer according to the vibration analytic result of detected earthquake motion as to the earthquake- resistance structure of the nuclear reactor container. CONSTITUTION:A hydraulic actuator 14 which has a hydraulic piston and a cylinder are installed at the fitting part on the side of the nuclear reactor container 2 and a rod 16 which is connected to the piston is fixed to the upper end of a nuclear reactor shield wall 8. The actuator 14 sends the electric signal from a process computer installed in a nuclear reactor building 1 to a hydraulic pressure source to control its rigidity. A response monitor detects earthquake motion, feeds it back at need, and controls the rigidity of the stabilizer 10. Consequently, the nuclear reactor pressure body main body and in-pile structure are reduced in earthquake response to improve the safety of the nuclear reactor.
