The reactor door of Nuclear Generating Area 3 from Force Of Life, also seen in Alpha Child.

The reactor door is glimpsed very briefly in The Exiles.

Power Room, in Life Support, in One Moment Of Humanity

The Power Room, seen briefly in The A B Chrysalis. The DANGER sign is seen only on the floor.

The vacuum chamber door from The Beta Cloud. Smaller DANGER signs on floor and door. Notice the side controls are only slightly changed from the nuclear reactor controls.

The waste dome Central Core door from The Bringers Of Wonder part 2. A big new EXTREME DANGER sign is over the door. For the first time, the side controls are changed.

The side control panel in The Beta Cloud is almost the same as in Force Of Life. At the top is a row of lights and switches (which here have "Vacuum Chamber" sign). The topmost of the five pipes is replaced with a pressure dial (with no numbers, just four colour-coded regions) and "Open" and "Close" buttons (helpfully labelled).

Four of the original pipes are still in place; we see Zoref pulling them out in Force Of Life to open the door), and the technician in The A B Chrysalis has some open.

The reactor door is also in the 1981 TV series Hitchhiker's Guide to the Galaxy, leading to the cryogenic pods on the Golgafrincham ark ship in episode 6 (thanks to Nick Macarty)
