Abstract
A method and apparatus for the calibration of neutron flux monitoring devices used in a nuclear reactor core. The apparatus includes a transverse in-core probe (TIP) cable with a neutron absorber located a fixed distance apart from a TIP detector. The neutron absorber may be passed within close proximity of the neutron flux monitoring device such that a perceived drop in measured neutron flux occurs, whereupon the cable may be repositioned relative to the monitoring device to ensure that the TIP detector is within close proximity of the monitoring device for purposes of calibrating the monitoring device.
Claims5
A Transverse In-Core Probe (TIP), comprising:
- a cable;
- a TIP detector attached to the cable;
- and
- a neutron absorber affixed to the cable, a fixed distance apart from the TIP detector, wherein the neutron absorber comprises Boron-10, Cadmium or Hafnium.
A Transverse In-Core Probe (TIP), comprising:
- a cable;
- a TIP detector attached to the cable;
- and
- an extension attached to an end of the cable, the extension including a neutron absorber, wherein the neutron absorber comprises Boron-10, Cadmium or Hafnium,
- wherein the TIP detector and the neutron absorber are a fixed distance apart from each other.
