Abstract: The condition-based maintenance of the nuclear reactor, by monitoring and measuring the instantaneous dynamic pressure-distribution of the coolant (water) impact on the solid surfaces of the reactor during operation is presented. The behaviour of water domes (jets) produced by underwater explosions of small charges of P.E.T.N. at various depths in two different size cylindrical containers, which simulate the nuclear reactor, is investigated. Water surface domes (jets) from the underwater explosions are photographed by means of high speed camera. Depending on the depth of the charge, curved and flat top jets of up to 455 mm diameter and impact speeds of up to 70 m/sec. are observed. The instabilities in the dome surfaces are observed and the instantaneous profiles are analyzed. Pressure measurements at the interface of the water dome (jets) impact on a flat surface are taken, and various instantaneous pressure-distribution curves are obtained for all tests. It is found that, in all cases tested, the maximum pressure takes place at the center of the jet and could reach up to 3.0 times the one-dimensional impact pressure value. Finally, the use of these measurements, as on-line monitoring for condition-based maintenance and design-out maintenance is discussed.
