Development is described of a device to detect holes in the fuel-rod sheaths in an H2O-cooled heterogeneous reactor by detecting delayed-neutrons from fission products in the effluent coolant. Operational comparison with other types of monitors is tabulated for 22 cases of burst rod sheaths. Modifications required to adapt the monitor to a D2O-cooled reactor are discussed.
