In a turbojet thrust reverser comprising, in an annular section of an outer cowling of the turbojet, a number of movable doors which, in an inactive position during operation in a forward thrust configuration, close off passages separating rigid spars of a fixed structure, there is provided, between two adjacent doors, a locking system which allows substantially simultaneous opening of the two doors. The locking system comprises, for each door, at least one hook mounted on the fixed structure so that it can be pivoted by an olive secured to the door between a door locking position and an unlocked position during opening or closing movement of the door. The two hooks of the locking system are rotationally interlinked by a mechanical linkage device, for example link rods, so as to prevent the unlocking of one door if the other door is closed.

A cleaning device in accordance with claim 5 wherein said sleeve is positioned between said nose and said connector. 7. A cleaning device in accordance with claim 6 wherein said body comprises at least one ring port in fluid communication with said center bore and said at least one sleeve port. 8. A cleaning device in accordance with claim 7 wherein said sleeve is rotated around said body by fluid passing from said center bore through said sleeve port. 9. A cleaning assembly for a jet pump nozzle in a nuclear reactor, said cleaning assembly comprising: a high-pressure pump; a high-pressure hose coupled to said high-pressure pump; a fluid control valve configured to regulate fluid flow through said high-pressure-hose; a handling pole; and a cleaning device coupled to said high-pressure hose downstream of said fluid control valve, said cleaning device comprising: a tubing section having a first end, a second end and a mid-section between said first end and said second end, said second end coupled to said high-pressure hose; a pole adapter coupled to said tubing section tubing section mid-section and releasably attachable to said handling pole; and a hydrolaze head assembly coupled to said tubing section first end. 10. A cleaning assembly in accordance with claim 9 wherein said tubing section first end comprises a semi-circular bend. 11. A handling assembly in accordance with claim 9 wherein said tubing section comprises a high pressure tubing section. 12. A cleaning assembly in accordance with claim 9 wherein said hydrolaze head assembly further comprises a nose, a body, a connector coupled to said tubing section first end, and a center bore in fluid communication with said tubing section. 13. A cleaning assembly in accordance with claim 12 wherein said hydrolaze head assembly further comprises a sleeve between said nose and said connector, said sleeve rotatable around said body. 14. A cleaning assembly in accordance with claim 13 wherein said sleeve comprises at least one sleeve port in fluid communication with said center bore. 15. A cleaning assembly in accordance with claim 14 wherein said sleeve is rotated around said body by fluid passing from said center bore through said sleeve port. 16. A cleaning assembly in accordance with claim 9 wherein said high-pressure pump provides fluid at between about 8,000 psi (550 kgf/cm2) pressure to about 15,000 psi (1050 kgf/cm2) pressure.
