Abstract

887,392. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. June 17, 1960 [July 6, 1959], No. 23106/59. Class 39(4) A control apparatus for a nuclear reactor comprises means for deriving a primary control term from a temperature measurement taken at a point in the reactor core, means for deriving an additional control term as a function of reactor flux and coolant flow, and means for combining the two terms to provide a composite control term. In the Figure the reactor is provided with a plurality of thermocouples 18 (of which only one is shown) for measuring the temperature of gas emerging from a fuel channel, each thermocouple being connected to one contact of a multi-position switch 22 so that the output of any one of them may be used. The primary control term is derived by subtracting the output of one of the thermocouples 18 from a reference voltage derived from potentiometer 34. The reactor is also provided with a neutron flux measuring in chamber 28 and with a flow meter 30 for producing a voltage proportional to the coolant flow in the inlet duct. The voltages produced by these two units are subtracted in unit 29 and differentiated with respect to time to give an additional control term which is fed to amplifier 32. The output of amplifier 32 is used to control the motor which raises or lowers the control rod 15. The rate of change of temperature may be used as the primary control term instead of the temperature itself.
