Main Steam Pipe Run (Nuclear Power Station and Control Room)
A 4 m bay of pipe gallery standing on its own floor stands: a 680 mm lagged main at 2.2 m with a smaller feed line and a copper service line beside it, saddle clamped at each stand. End ports run the gallery across a plant floor.
Shell and Tube Heat Exchanger (Nuclear Power Station and Control Room)
A 4.2 m shell and tube heat exchanger on two concrete saddles: a 1.24 m shell with dished and flanged heads, four flanged nozzles top and bottom, a vent standpipe and a blank rating plate.
Feedwater Pump Set (Nuclear Power Station and Control Room)
Two horizontal feed pumps on a shared concrete plinth: each a motor with a guarded coupling driving a volute casing, with a flanged discharge riser, a suction bend and a side-mounted isolating handwheel.
Turbine Shaft Line (Nuclear Power Station and Control Room)
A 5.2 m length of shaft line between two bearing pedestals: a 400 mm shaft with coupling flanges at both ends, a barring gear wheel, oil pipework with sight glasses, and the turning gear drive standing beside it.
Condenser (Nuclear Power Station and Control Room)
A 6 m surface condenser: a welded shell on a hotwell, a bolted water box at each end with a flanged circulating water branch, the exhaust neck and its expansion bellows on top, and the air offtake off one corner.
Turbo Generator Set (Nuclear Power Station and Control Room)
A 7 m turbo generator on its plinth: a ribbed stator body with end shields, a terminal box with three bushings, a cooler run down the back, an exciter on the outboard end, and a grating walkway with handrail down the operating side.
Turbine Casing (Nuclear Power Station and Control Room)
A 6.4 m horizontally split turbine casing on its concrete plinth: a tapered barrel with a bolted joint flange down each side, three steam belts, two extraction branches with flanges, and a bearing housing at each end.
Control Rod Stand (Nuclear Power Station and Control Room)
A stand of five spare control rod clusters: 3.4 m absorber fingers hanging from their spiders in a bolted frame with two guide beams, on a footed base plate with a trefoil on the front.
Fuel Assembly on Cradle (Nuclear Power Station and Control Room)
A 4 m square fuel assembly lying on its handling cradle: a thirty six rod bundle with five spacer grids and both end nozzles, strapped across two bolsters on a wheeled frame with a lifting bail at one end.
Fuel Lifting Flask (Nuclear Power Station and Control Room)
A 1.7 m diameter shielded transfer flask 2.7 m tall: a finned body on a transport base, two lifting trunnions, a machined seal face and a bolted lid hinged at the back, with a trefoil on the flank.
Spent Fuel Storage Rack (Nuclear Power Station and Control Room)
A 1.56 m square storage rack for a fuel pond: thirty six neutron absorbing cells on a 260 mm pitch, 2.4 m deep, on a footed base plate with levelling pads and four lifting eyes.
Spent Fuel Pond Corner (Nuclear Power Station and Control Room)
The pond bay with a second coping kerb and handrail down its side edge, for closing the end of a pond. Its two ports face along each kerb.
Spent Fuel Pond Edge (Nuclear Power Station and Control Room)
A 4 m bay of spent fuel pond: a concrete coping kerb along one edge with a handrail and a trefoil badge, a skimmer weir let into it, the lined floor of the basin and the water surface 240 mm down. End ports run it into a pond of any size.
Reactor Hall Gantry Crane (Nuclear Power Station and Control Room)
A 12 m span portal crane 9 m to the bridge: braced legs on rail trucks with access ladders, twin box girders with a grating walkway and handrail, and a crab carrying the rope drum and its motor.
Refuelling Machine (Nuclear Power Station and Control Room)
A portal refuelling machine on travelling trucks, 8 m between legs and 5.4 m to the bridge: twin girders with a grating walkway and handrail, a traversing trolley and a telescopic mast with a gripper hoist under it, plus an operator platform and ladder on one leg.
Crane Hook Block (Nuclear Power Station and Control Room)
A two sheave hook block set down on the floor under its rope: a plate body with side sheaves, a swivel hook with a safety catch and a painted badge on the cheek. The block runs up and down on its own node.
Reactor Vessel Head with Control Rod Drives (Nuclear Power Station and Control Room)
A 5.8 m reactor vessel head: a bolted flange with twenty four nuts, a domed shell, and thirty seven control rod drive mechanisms standing on it in four rings, tied by a seismic support ring, with four lifting lugs and a blank rating plate.
Reactor Cavity Ring (Nuclear Power Station and Control Room)
The concrete cavity the vessel sits in: a 7.2 m stepped pit 1.8 m proud of the floor with a 5 m bore, a machined seal ledge and twenty four hold-down studs round it, edge protection on two sides and a trefoil on the kerb.
Containment Dome Section with Equipment Hatch (Nuclear Power Station and Control Room)
The containment section with a 3 m equipment hatch cast through the wall: a recessed barrel and a bolted steel cover on sixteen studs, at 2.6 m above the floor.
Containment Dome Section (Nuclear Power Station and Control Room)
A 90 degree cutaway section of a containment shell: an 800 mm concrete wall 7 m high on a haunched plinth, curving into the dome and sawn off at a ring beam 12 m up, with five buttresses and the steel liner inside. Two sections back to back make a half shell to look into.
Access Ladder with Hoops (Nuclear Power Station and Control Room)
A 3.6 m galvanised cage ladder: 34 mm rungs between channel stiles, hoop guards from 2.2 m up on a back stringer, and two wall brackets holding it off the structure.
Stair Tower (Nuclear Power Station and Control Room)
A bolted steel stair tower climbing 4 m in two flights round a half landing: ten grating treads a flight on channel stringers, a grating landing at each level on edge beams, four corner columns, and a sloped rail on posts up both sides of every flight.
Handrail Run (Nuclear Power Station and Control Room)
A 4 m run of plant handrail: a 48 mm top rail and a knee rail on three flanged posts, with a toe plate along the bottom and a painted band at each post. End ports run it round a floor edge.
Walkway Grating Section (Nuclear Power Station and Control Room)
A 4 by 1.2 m galvanised walkway panel: 40 mm bearing bars on 130 mm centres with cross bars, edge angles and a bearer at each end. End ports run it into a walkway of any length.
