Title: Drive mechanim for neutron aborbing rod
Inventor: HATTORI SADAO
IPC: G21C7/14
Filed: 1992-12-03
Abstract: PURPOSE:To eliminate the possibility of a neutron absorbing rod being extracted from a reactor core by mistake so as to enhance safety by preventing the neutron absorbing rod from being attracted to a neutron-absorbing rod holding rod by an electromagnet before the temperature of a coolant reaches a predetermined value. CONSTITUTION:An electromagnet 34 comprising a coil 32 and an iron core 33 is mounted at the lower end of a neutron-absorbing rod holding rod 31 located above a neutron absorbing rod 30 for insertion into a reactor core. A guide 35 is provided to pass through the holding rod 31 and the electromagnet 34. The lower end of the guide 35 is formed with an acute cross section to abut to a recess formed in the upper surface of the absorbing rod 30. If a coolant is heated to 350 deg.C at the startup of the reactor core, the coefficient of thermal expansion of the holding rod 31 is made greater than that of the guide 35 by changing the materials from which the rod and the guide are made, so that the distance between the lower ends of the electromagnet 34 and the guide 35 decreases. Therefore, the absorbing rod 30 is not attracted to the electromagnet 34 before the temperature of the coolant reaches a predetermined value, and so the possibility of extracting the absorbing rod 30 from the core by mistake is eliminated and safety is enhanced.

Filed: 1992-12-03
Abstract: PURPOSE:To reduce the possibility that a disturbing signal is received while being superimposed on a desired signal by tuning a desired frequency from an output of an amplifier circuit with a flat gain frequency characteristic when the disturbing signal is in existence and from an output of an amplifier circuit with a selectivity characteristic when the disturbing signal is not in existence through selection respectively. CONSTITUTION:An output from a high frequency amplifier circuit 10 and an oscillating output from a local oscillation circuit 4 are mixed at a mixer circuit 20. Then frequency information being a difference frequency of the two waves and signal intensity information converted into a signal proportional to an output signal from the circuit 10 are given to an intermediate frequency amplifier circuit 30. The circuit 30 amplifies and detects a received signal and gives the frequency information and a DC output proportional to the signal intensity being the signal intensity information from the output terminal to the microcomputer 50 respectively. The microcomputer 50 receives the sets of the information and compares the signal intensity information with the preset information. When the signal intensity information is smaller than the preset value, it is discriminated that no disturbing signal is in existence, the reception of a desired frequency f2 is designated and when higher, it is discriminated that the disturbing signal is in existence and a changeover means selects a required amplifier circuit.
