In addition to the reactor hall, a hot cell room, a spare blanket storage room, and a new blanket assembly room are needed. The first three rooms will each be 16 by 16 meters, and the new blanket assembly room will be 16 by 32 meters. The increased size of the assembly room allows for large component laydown space prior to assembly. Some of these activities can take place in the same area at different times. 1 Use of Flibe Two great advantages of flowing lithium-bearing coolants are the simplicity of the blanket and the fact that only an empty shell needs to be periodically changed out.

E. KH = 7 x lo-’ moles T2 m3 (salt) Pa ’ at 1000 K. Based upon this relationship and the value of the T, concentration in the salt, we 2-44 calculate a T, pressure of 820 Pa. At such a high pressure T2gas would permeate easily through the IHX and be lost to the environment. It is necessary, therefore, to reduce the T,concentration in the salt before it reaches the IHX to a level so that the tritium permeation rate is acceptable. Tritium is removed from Flibe as it cascades down the back of the blanket and is then pumped out by the chamber vacuum systems.

15. 2 Fuel Reprocessing Target factory The Reactor and Meat Transfer System. This system consists of the total Flibe in the reactor, the vacuum disengager, the IHX and the connecting pipes for a total of 470 m3 (940,000 kg). 8 x 10" moles (T2)/m3while the other 50% is at a concentration of -lo-*moles (T,)/m3; consequently, the total tritium inventory in Flibe is -1 g(T). In a severe accident, perhaps only 50% of the gaseous tritium would be released before the salt solidifies, because there is no major radioactive nuclides in this salt to prQlong its heating.
