The two diagrams on the same page are labeled: Figure 5 Typical BWR Mark I Concrete Containment with Steel Torus.
The report text describing the diagrams, on page 10 (pdf 35) is:
BWR Mark I
The Mark I is a pressure suppression containment (Figure 5), which allows the containment to be smaller in volume. The containment is divided into the drywell containing the reactor vessel and the wetwell (torus) containing the suppression pool. The containments are constructed of either concrete or steel. The water in the suppression pool acts as an energy absorbing medium in the event of an accident. If a LOCA [loss of coolant accident] occurs, steam flows from the drywell through a set of vent lines and downcomers into the suppression pool, where the steam is condensed. Steam can also be released from the reactor vessel through the safety relief valves and associated piping directly into the suppression pool. In the event that the pressure in the wetwell exceeds the pressure in the drywell, vacuum breakers are provided that equalize the pressure. Mark I containments are equipped with lines connected to the wetwell that can be used to vent the containment if the pressure becomes too high.
