Abstract
1,048,423. Controlling reactors. ENGLISH ELECTRIC CO. Ltd. Aug. 20, 1964 [Aug. 23, 1963], No. 33409/63. Heading G6C [Also in Division G1] To check that a number of reactivity control rods 10 in the core of a reactor, which are each operated by separate drive means 13, move in synchronism each is coupled to one of a like number of coaxially arranged discs 17 provided with a number of holes 18. A source of radiation 20 at the focus of lens 21 provides a parallel beam passing through aperture 23 covering one pitch of the series of holes 18. If all the discs have their holes in alignment the maximum amount of radiation will pass through them, through aperture 24 similar to 23, and be directed by lens 25 to detector 26. Synchronous rotation of the discs 17 will not affect the amount of radiation reaching the detector, but if one or more discs move to cause misalignment the detector output will fall. If it drops below a certain level, a switch 28 causes alarm 29 to operate. A chopper disc 22 can be used to modulate the radiation beam to produce an A.C. signal in the detector circuit.
