摘要： The invention relates in particular to an improved retaining pin assembly (10) comprising a retaining pin (16) which has a first pin portion (18) adapted to be inserted through a passage (26) in the end flange (14) of a control-rod guide tube and to be affixed thereto by means of a nut (40), and has a second pin portion (20) which comprises a split-leaf base section (24) and is adapted to be received in a bore (22) of the upper reactor-core plate (12).
Adjacent its end contiguous to the first pin portion, the second pin portion (20) is provided with a solid body section (50) which is sized to form a close-clearance fit with the wall of the core plate bore (22) so as to react, substantially in pure shear, any lateral loads applied to the retaining pin (16), the split-leaf base section (24) including a split stem (54) which has a smaller diametral dimension than the solid body section and extends axially therefrom, terminating in a split end section (56) biased against the wall of the core plate bore (22). The nut (40) has formed integral therewith a tubular extension (60) crimped to an end section (28) of the first pin portion to prevent self-loosening of the nut, and a longitudinally split sleeve-like nut retainer (70) is provided to lock the nut (40) to the guide-tube flange (14).

摘要： A nuclear reactor reflector is disclosed that comprises a stack (11) of reflector blocks (10.1-10.8) with vertical water flow passages to cool the reflector. The interface between blocks is opposite support points for reactor fuel rods (16). Water flows between the reflector and the reactor barrel (20) from passages (30) in a bottom block (10.1). The top block (10.8) contains a flange (10.81) to limit this flow and the flange has a slot (10.83) to receive an alignment pin (10.60) that is welded to the barrel. The pin is held in the slot by two removable shims (62). Alignment bars (80) extend the length of the stack in slots machined in each block when the stack is assembled.

摘要： A retaining pin mounting assembly for nuclear reactor guide tubes including a pin (16) having a one end portion for disposition within a bore in the upper core plate (12) of a reactor, while the other end (24) is to extend through a bore (22) of the guide tube flange (14) and has a threaded region (30) for threadedly receiving a nut (32) provided with a locking cap (46). The pin has a flange and a shank (24) of a diameter smaller than the bore (22) with guide tube flange (14) and the nut (32) has a skirt (33) adapted to engage the flange (14) and having an inner diameter larger than the shank (24) such that an annular space is formed around the shank. Radial flow apertures 60 extend through the skirt (33) of the nut 32 so as to permit coolant flow through the annular space around the pin shank (24) in order to prevent corrosion by differences in the concentrations of the reactor coolant from that around the pin shank (24).

摘要： A guide tube insert assembly (110) for receiving and guiding a control rod assembly (27) through mutually aligned apertures (18a, 18b, 24) formed in an upper support plate (22) and an upper core plate (12) of a nuclear reactor (1). The guide tube insert assembly (110) includes a plurality of guide plates (112, 112', 114, 128) with each guide plate (112, 112', 114, 128) including a plurality of bores (126) with respective bores (126) of each of the guide plates (112, 112', 114, 128) being axially aligned with one another so as to form a plurality of axial passages (126) for conducting rodlets (122) of the control rod assembly (27) into and out of the fuel rod assemblies (14) of a nuclear reactor (1). A plurality of tie rods (122) are provided and extend between an uppermost guide plate and a lowermost guide plate (112'), the tie rods (122) being surrounded by a plurality of spacer sleeves (124) so as to space the guide plates (112, 112', 128) a predetermined distance from one another. The tie rods (122) maintain a predetermined spacing between each of the plurality of guide plates (112, 112', 128) and allow the plurality of guide plates (112, 112', 128) to be simultaneously removed from within a guide tube (26) extending between the upper core plate (12) and the upper support plate (22).
