The drawing is a very rough draft, not to scale and placement is not exact but it will give a better idea where
things are. I have also included images below the drawing to help show how I developed the map.
1. Spent fuel pool. We have a number of images of 3 and 4 that show the rough location of the fuel pool. #3 we can see the inner
wall clearly. On 4 we can see into the pool from the end of the building. The location of the refueling crane on #4 also gives some
ideas of the general location. There are also a number of images of the SFP from before the quake.
2. Reactor Well
We have some rough glimpses of the area where the well is from fly over images. This interior image from before the
quake tells where the well is quite clearly.
3. Tool Pit (aka) steam dryer pool
This area has caused a few questions. It is labeled differently on various documents. The best
estimate from talking to people is that it is a pit for tools needed to work on the reactor.
There are some images of the remains of #3 that show it.
4. Cap Fitting Carousel
This curious looking item took some research. A number of people found out what it is. This odd
thing is used to torque down the reactor cap so it is installed properly. The hydraulic drivers screw
in bolts on opposite sides so the cap is seated evenly and properly.
5. Steam Condenser
This silver looking thing is part of the reactor assembly and parts. It can be seen in the upper corner of this
image behind the yellow containment cap.
6. Containment Cap
It can be seen in the image above and in many of the shots of building 4.
7. Reactor Cap
This one is not caught in the inside images and has been elusive in research on building 4.
It looks like the image below
8. Control Room and Elevator
The image below shows the control room in the corner and also a swing over crane. This same general
area that can be seen on the overhead view of reactor 3 has a hole that looks like an elevator shaft in that area.
