Abstract
Abstract The removable head of a pressure vessel enclosure for a nuclear reactor is penetrated by a bundle of hydraulic control lines. The vessel top head is provided with a single aperture and a connector assembly is installed in the aperture; the connector assembly providing leak proof coupling of external control lines to corresponding internal control lines of the bundle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
234 words
Apparatus for transmitting a plurality of fluidic signals through the nuclear reactor removable head of a pressure vessel, said removable head having an aperture therein said transmitting apparatus comprising: inner flange means, said inner flange means having a plurality of passages therethrough, said inner flange means having a shape commensurate with and a maximum size in excess of the respective shape and size of the pressure head aperture; means mounting said inner flange means to the interior of the vessel head whereby said inner flange means cover the head aperture; apertured support means mounted internally of the pressure vessel, said support means having a shoulder about the aperture therein, said shoulder engaging said inner flange means about its peripery and supporting said inner flange means when said mounting means are removed; outer flange means, said outer flange means having a plurality of passages therethrough, the passages in said outer flange means defining a pattern commensurate with the pattern of passages in the inner flange means, said outer flange means having a size and shape complementary to the size and shape of the pressure vessel head aperture whereby said outer flange means will be received in said aperture; and means aTtaching said outer flange means to said inner flange means with the passages in said flange means aligned whereby communication between the interior and exterior of the pressure vessel is provided by said aligned passages.
Claim 2
Dependent Claim
234 words
Apparatus for transmitting a plurality of fluidic signals through the nuclear reactor removable head of a pressure vessel, said removable head having an aperture therein said transmitting apparatus comprising: inner flange means, said inner flange means having a plurality of passages therethrough, said inner flange means having a shape commensurate with and a maximum size in excess of the respective shape and size of the pressure head aperture; means mounting said inner flange means to the interior of the vessel head whereby said inner flange means cover the head aperture; apertured support means mounted internally of the pressure vessel, said support means having a shoulder about the aperture therein, said shoulder engaging said inner flange means about its peripery and supporting said inner flange means when said mounting means are removed; outer flange means, said outer flange means having a plurality of passages therethrough, the passages in said outer flange means defining a pattern commensurate with the pattern of passages in the inner flange means, said outer flange means having a size and shape complementary to the size and shape of the pressure vessel head aperture whereby said outer flange means will be received in said aperture; and means aTtaching said outer flange means to said inner flange means with the passages in said flange means aligned whereby communication between the interior and exterior of the pressure vessel is provided by said aligned passages.
Claim 3
Dependent Claim
56 words
The apparatus of claim 1 further comprising: seal plate means disposed between said flange means, said seal plate means being provided with a number of apertures commensurate with the number of passages in said flange means, said seal plate means apertures being arranged in a pattern commensurate with the flange means passage pattern and aligned therewith
Claim 4
Dependent Claim
47 words
the apparatus of claim 1 wherein said inner flange means mounting means comprises: a plurality of bolts which pass through the pressure vessel head and engage said inner flange means internally of the pressure vessel, the heads of said bolts being external of the pressure vessel head.
Claim 5
Dependent Claim
55 words
The apparatus of claim 3 further comprising: seal plate means disposed between said flange means, said seal plate means being provided with a number of apertures commensurate with the number of passages in said flange means, said seal plate means apertures being arranged in a pattern commensurate with the flange means passage and aligned therewith.
Claim 6
Dependent Claim
95 words
The apparatus of claim 1 wherein said inner flange means comprises: a first portion having a size and shape complementary to the size and shape of the pressure vessel head aperture, the said first portion receiving and engaging said outer flange means attaching means and being received in said pressure vessel head aperture with the transmitting apparatus in the assembled condition; and a second portion extending outwardly from said first portion, said second portion receiving and engaging said inner flange means mounting means, said inner flange means passages extending through said first and second portions.
Claim 7
Dependent Claim
47 words
The apparatus of claim 5 wherein said inner flange means mounting means comprises: a plurality of bolts which pass through the pressure vessel head and engage said inner flange means internally of the pressure vessel, the heads of said bolts being external of the pressure vessel head.
Claim 8
Dependent Claim
29 words
The apparatus of claim 6 further comprising: seal means disposed between the top of the inner flange means second portion and the inner wall of the pressure vessel head.
Claim 9
Dependent Claim
56 words
The apparatus of claim 7 further comprising: seal plate means disposed between said flange means, said seal plate means being provided with a number of apertures commensurate with the number of passages in said flange means, said seal plate means apertures being arranged in a pattern commensurate with the flange means passage pattern and aligned therewith.
