Title: Pressure vessel for a nuclear reactor
Inventor: DUPUY GERARD
IPC: G21C11/08
Filed: 1964-10-26
Abstract: 1,027,094. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Oct. 26, 1964 [Oct. 30, 1963], No. 43557/64. Heading G6C. A pressure vessel for a swimming pool nuclear reactor with a forced-circulation watercooled core is pierced with channels in the thickness of its wall for a cooling water flow parallel with the direction of the water flow through a core, each channel containing a bar whose cross-section is substantially similar to that of the channel and which has means for being centered in the channel in order to reduce the water coolant flow through the channel to a thin film. Such a coolant flow causes little disturbance of the neutron flux outside the pressure vessel. In the swimming pool reactor shown in Fig. 1, the core 1 comprises juxtaposed fuel elements 2 in which the fissile material is in the form of parallel plates cooled by water which is forced upwards through a pressure vessel 4 surrounding the core 1, from an inlet sump 5 to an outlet conduit 7. The pressure vessel 4 comprises four prismatic elements 8-11 placed one above another. The elements 9, 10 which surround the reactor core are made of " Zircaloy," a zirconium alloy which absorbs gamma radiation, while the bottom element 8 and the top element 11 which experience loss gamma radiation are made of aluminium. Vertical parallel channels such as 12, 13 are pierced inside the pressure vessel walls and contain bars, such as 18, 19, of " Zircaloy " to limit the flow of cooling water to a thin film. The cooling water enters the channels 12, 13 through apertures 14, 15 at the bottom of the pressure vessel and leaves through apertures 16, 17 at the top of the pressure vessel, being derived from the main water flow. Some of the bars 12, 13 serve merely to limit the cooling water flow while others serve additionally to assemble the pressure vessel elements 8-11 or to secure the pressure vessel to the sump 5.

Title: Unbalanced pressure shaft seal
IPC: F16J15/54
Filed: 1964-10-28
Abstract: 1,020,397. Seals. CESSNA AIRCRAFT CO. Oct. 28, 1964 [Nov. 12, 1963], No. 44053/64. Heading F2B. A pressure-closed annular seal between a journal member and a journaling member which expose circumferential portions of one end of a clearance space between the members to separated zones of high and low pressure comprises an annular seal arranged in a groove in one of the members, the arrangement being such that an end wall of the groove defines, in conjunction with the adjacent member, a twosurface valve seat and fluid from a zone of high pressure forces its way between the seal and seat into the groove, travels circumferentially around the groove to a position adjacent a zone of low pressure and, in attempting to pass the seal into the zone of low pressure, closes the seal on to its seat. As applied to a vane type hydraulic motor, Fig. 5, a wedge-shaped seal 33 is made of P.T.F.E. and formed with serrations 34 on its base. In operation, fluid on the high pressure side 22 of the vane 15 leaks into the groove 31 and travels, as indicated by the arrows, circumferentially towards the low pressure side 21 where it lifts the seal on to its seat. The bearing is lubricated by the fluid which passes down the clearance 67 to a further sealing arrangement 38. In Fig. 6 (not shown) the seal 53 is lightly-pressed on its seat by a spring 55. In Fig. 7 (not shown), an 0-ring 73 under compression serves to urge the seal 68 on its seat and prevent leakage past the outer end of the journal 70. In Fig. 9 (not shown), a U-shaped seal 80 is provided, the legs of the U being directed inwardly; when high pressure fluid leaks past the face 77 it forces the seal on to its seat so as to prevent escape of the fluid into the zone of low pressure and past the outer end of the journal 76. The seal may also be applied to a Corliss type valve.
