Title: Water level controller at start and stop of reactor
Inventor: FUJINAMI MASARU
IPC: G21D3/00
Filed: 1989-06-05
Abstract: PURPOSE:To eliminate useless control to stabilize a water level by allowing the device to output an opening instruction when a deviation signal between a reactor water level and a water level set point is higher than a specified value and making constitution for restoring the opening instruction when a deviation becomes zero. CONSTITUTION:When a water feed regulating valve 3 and a CUV blowing-down valve 5 are wholly opened and a reactor water level 2 is put at a specified position, a steam flow is increased to lower a water level 2 if output is increased. When an integrator 12 is allowed to integrate a deviation between a reactor water level signal 6 and a reactor water level set signal 7 in the positive direction and its output exceeds a set point of a comparator 14, an opening instruction is output from an open bias setter 18 to a valve 3 to feed water, and when a water level 3 becomes a set point, the integrator 12 is allowed to reset by a deviation monitoring comparator 13 so as to restore the opening instruction to zero. In a case where the water level 2 increases, the same operation is performed to a valve 5 to lower the water level 2. Next, at the time of water level fluctuation accompanied by a pressure disturbance, the water level 2 seeminly increases for a time by pressure lowering due to start of a high pressure injection system, but sharp fluctuations of the water level 2 do not produce because the output of the integrator 12 does not increase steeply.

Light emitted from a light-emitting element 4a for distance measurement of a position detecting means 4 is reflected by a reflector 22 of the target 2 and the reflected light is received by a light-receiving element 4b for distance measurement of the position detecting means 4. Therefore the distance to the target 2 is measured on the basis of the principle of an electronic distance measuring device, while the angle of direction of the position detecting means 4 to the target 2 is measured, and the space coordinates of the target 2 are determined from these distance and angle. This measurement is executed for the targets 2a and 2b in a plurality. Since the ferrule parts 3a and 3b are disposed on the same straight line as these targets 2a and 2b, the space coordinates of the position indicated by the ferrule parts 3a and 3b can be calculated.
