A Computer Controlled Irradiation System for the University of Missouri Research Reactor

  • R. Berliner
  • S. Wood


A computer controlled irradiation monitoring system has been designed and is being installed at the University of Missouri Research Reactor. The system utilizes rhodium wire self-powered neutron detectors and a multiplexed data input system with BIC current integrators to monitor the specimen flux. A PDP 11/03 computer is used to maintain a memory image of the current status of all the in-pool specimens and to alert the reactor operators to required specimen handling procedures. The PDP 11/03 computer is in periodic communication with a PDP 11/40 which maintains in its disk files a record of previous irradiations and the schedule for future irradiations. Separate programs which are run on the PDP 11/40 provide for specimen logging, calculation of irradiation parameters, scheduling of irradiations and continuous recalibration of the detectors.

The system has been designed to be resistant to failure of either of its computers and to provide protection against power interruptions.

The system hardware will be described and the system software block diagrams will be discussed.
