AnimatedValve Handwheel Bank (Nuclear Power Station and Control Room)
A manifold stand of six isolating valves between two headers, 2.4 m wide and 2.3 m tall: each valve a bonneted body on a side-mounted stem with a spoked handwheel that turns, with a blank tag strip under every one.
AnimatedMain Steam Pipe Run with Valves (Nuclear Power Station and Control Room)
The pipe gallery bay with two flanged gate valves in it, each with a side-mounted stem and a spoked handwheel that turns, for breaking a run where it needs isolating.
Steam Drum Vessel (Nuclear Power Station and Control Room)
A 2.1 m diameter vertical steam drum 4.4 m tall: a dished top and bottom, lagging straps, a bolted manway on the flank, two flanged crown nozzles, a gauge glass, and an access platform with handrail and ladder.
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.
AnimatedFeedwater 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.
AnimatedTurbine 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.
AnimatedFuel 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 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.
AnimatedReactor 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.
AnimatedRefuelling 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.
AnimatedCrane 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.
