1. An apparatus for detecting and locating leaks in a nuclear plant, comprising: a collection line permeable to a substance to be detected;  a pump communicating with said collection line;  a sensor communicating with said collection line for sensing the substance, said sensor not suited to detecting radioactivity of the substance;  a detector communicating with said collection line for detecting radioactivity of the substance; and  a suction pump associated with said detector. 2. The apparatus according to claim 1, wherein said collection line is disposed in the vicinity of a pipeline of a nuclear plant. 3. The apparatus according to claim 1, including a branch line branching off said collection line upstream of said sensor and communicating with said detector. 4. The apparatus according to claim 1, including a supply container in which said detector is disposed. 5. The apparatus according to claim 1, including a valve disposed upstream of said collection line. 6. The apparatus according to claim 1, including check valves disposed at spaced-apart openings formed in said collection line, said check valves opening if a predetermined pressure fails to be exceeded. 7.
