Abstract
A mounting for power conductor and instrument lead penetrations in nuclear reactors provides a device that is simple, compact and at the same time easily installed, repaired or replaced. The mounting comprises a cylinder like, stepped housing which is to pass through the pressure vessel wall of the nuclear reactor and house at least one and preferably a plurality of electrical conductors.
Claims15
A mounting construction for power conductors and instrument leads passing through a wall of a nuclear reactor pressure vessel comprising:
- a cylindrical metal housing having a first outer circumference larger than a second outer circumference and a shoulder area between said first and second circumferences, said cylindrical metal housing being tightly fitted along its length and outer circumference in a passageway in said nuclear reactor pressure vessel wall, and terminating with a part of said first outer circumference inside said pressure vessel;
- a metal, cylindrical tube segment tightly surrounding said part of the first outer circumference within said pressure vessel and fixedly attached thereto with a lip weld;
- at least one electrical conductor extending through the length of said cylindrical metal housing, and
- solid filler material at least partially filling the space within said cylindrical metal housing.
