Title: Method for deciding cooling state of hot roller plate of high carbon steel
Inventor: KONISHI SEIJI
IPC: C21D9/52
Filed: 1990-09-28
Abstract: PURPOSE:To provide a method for deciding cooling conditions applicable to the control of the cooling hysteresis of a hot rolled steel plate with high preci sion by quantitatively predicting, at real time, complicated transformation behav ior showing a temp. reversing phenomenon like that of a high carbon steel. CONSTITUTION:A transformation start temp. (Ts) is determined from average cooling velocity in the course of passing through a unit cooling zone on ROT because it changes according to steel material cooling velocity. Ts=f(CR). Further, it is decided that transformation is started at the moment when the temp. of the steel plate becomes lower than the temp. Ts. Transformation proceeding velocity is predicted by dX/dt=g(T). As the calorific value in the course of the progress of transformation mentioned above, the total transformation calorific value specified according to the type of steel is represented by Q[kcal/m<3>] and transformation calorific velocity q[kcal/(m<3>Hr)] is represented by Q.dX/dt[kcal/(m<3>Hr)], and further, the experimental calorific value Q' can be represented by integral  qdt[kcal/m<3>]. Further, the completion of transformation is decided by X=Q'/Q=1.0 (where X means transformation ratio).

Title: Operation method for pressurized water reactor
Inventor: NIIHARA TOSHIAKI
IPC: G21C7/08
Filed: 1988-10-19
Abstract: PURPOSE:To greatly increase the margin of evaluation in a control rod jump-out accident by inserting a control rod bank which has a control rod value of several %DELTArho into the upper part of a reactor core by a length of several tens of % of the axial length of the reactor core. CONSTITUTION:The jump-out accident of the control rod is assumed so that one control rod in banks C and D jumps out of the reactor core. At this time, fuel elements at the periphery of the jumping-out control rod increase in output and the output peaking factor in the reactor core varies. Namely, the maximum output distribution value FQ in the reactor core is defined by FQ infinity  FXYFZ, where FZ is the maximum value of the axial output distribution of the nuclear reactor and FXY is the maximum value of the horizontal output distribution. The operation of the nuclear reactor is so controlled that an upwardly one-sided axial output distribution is flattened to decrease the value FQ, thereby holding the value FQ almost so that the axial offset is nearly zero. This value FQ is decreased by inserting the control rod partially into the reactor core. Namely, the output of the upper part of the reactor core decreases by the insertion of the control rod, so the axial output distribution is flattened on the whole and the value FQ is decreased.
