Section: claims

1. A pressurizer of a nuclear power plant comprising: a casing having a wall and a lower region;  a volume-compensation line ending in said casing; and  a spray line only intended for cooling, said spray line guided through said wall in said lower region, extended upward inside said casing and ending in said casing at a geodetically highest point of said spray line. 2. The pressurizer of a nuclear power plant according to claim 1, wherein said spray line has at least one spray nozzle in the vicinity of said highest point. 3. The pressurizer of a nuclear power plant according to claim 2, wherein said spray line has a portion directed upward at an angle, said portion having said at least one spray nozzle. 4. The pressurizer of a nuclear power plant according to claim 1, wherein said lower region of said casing is a lower cylindrical part, and said spray line is guided through said wall in said lower cylindrical part at an oblique angle relative to said wall. 5. The pressurizer of a nuclear power plant according to claim 1, wherein said lower region of said casing is a lower cylindrical part, and said spray line is guided through said wall in said lower cylindrical part at right angles to said wall. 6. The pressurizer of a nuclear power plant according to claim 1, wherein said casing has a bottom and a dome-like part closing off said bottom, and said spray line is guided through said wall in said dome-like part at right angles to said wall. 7. The pressurizer of a nuclear power plant according to claim 1, wherein said spray line is guided through said wall at a location forming a fixed point.
