first with a %in. air gap between the two. A sim-
ilar second plate and air gap would be provided
for the floor. During reactor opetai ion, cooling
air would be circulated through the gap at a ve-
locity of about 50 fps to remove the heat gener-
ated by gamma absorptions in the wall. Cooling
air is also used in the removable roof plugs, the
air duct connections being flanged to facilitate
removal. The total heat losses from the reactor
cell are estimaled to be a maximum of 800,000

Btu/hr. The thermal shield could tolerate loss of
cooling air for up to 1 hr without an excessive
temperature rise.
A 3/,,-in.-lhick carbon steel membrane is in-
stalled inside the inner 3-in.-thick steel wall
mentioned above. This membrane is hermetically
tight and would satisfy the containment leak-rate
requirements. The membrane is continuous around
the top plugs and also at the penetrations of the
cell, as shown in Fig. 5.7. The space between it
