Title: Production method for fuel assembly
Inventor: YAMAGUCHI TAKASHI
IPC: G21C3/328
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To suppress the fluctuation of nuclear worth at the end period of operation cycle by using an equivalent fissile coefficient [B] of burning compensation method and determining the contents of each nuclear fuel material so that the effective multiplication factor at the end of operation cycle becomes nearly constant. SOLUTION: An arbitrary fuel component Wt has a nuclear worth equal to the component Wst at that moment if the following equation is satisfied at the time t. Et=F.Wt, where F is the fissile coefficient in reactivity conservation method. On the other hand, it has following relation with the component W0 at the beginning of burnup. Wt=Mt.W0 , where Mt is burnup matrix. Thus, equivalent nuclear worth at time t is obtained if the component of new fuel satisfies the following equation. Et=F.Mt.W0 =Bt.W0 . The equivalent fissile coefficient in burning compensation method is a function of time. By setting the time t appropriately, initial purpose can be attained. In other words, if time t is the end period of burnup, the fluctuation of effective multiplication factor at the end period of operation cycle can be extremely minimized.

Title: Combustion device
Inventor: TOMITA HIDEO
IPC: F23D14/16
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To eliminate horizontal vibration of film of a heat-resistant fiber mat, which causes resonance, and restrain pulsating combustion by fixedly attaching a damping steel plate formed of a steel plate and damping resin integrally to the rear side of the heat-resistant fiber mat. SOLUTION: When the concentration of premixed gas becomes an air-excess concentration, which often causes a lifted flame, for some reason, instability of the premixed flames increases fluctuation of reaction, such as temperature or pressure fluctuation. And a large pressure fluctuation gives rise to horizontal vibration of film of 100-250Hz in a heat-resistant fiber mat 14. The horizontal vibration of the mat 14 is transmitted to a damping resin layer 30 from bolts and nuts 27 through steel plate 28, 29 and the energy of vibration of the mat 14 is absorbed by the shearing deformation of the layer 30. That is, horizontal vibration of the mat, which causes resonance, is eliminated, and hence pulsating combustion can be restrained.
