Critical inventory and breeding ratio for a single-cell (1.0-m-diam), nonplasma reactor would be about 20-kg and 1.12, respectively. Depending on operating conditions, i.e., He/uFa pressure and flow rate, this concept could produce up to 300 MW(th). A four-cell reactor is not viable since dimensions cannot be adjusted to yield a breeding ratio greater than unity. Results for six- and seven-cell (0.5-m-diam) plasma concepts are shown in Fig. 2. These systems could deliver up to 600 MW(th) and, if 1.0-m-diam cells were employed, up to -2500 MW(th). 

Denaturing the feed with indicated that a uranium feed composition of 20 1 ( "U U) results in only a doubling of the critical inventory for singlecell concepts. However, the total uranium inventory is 40 times greater than for the pure core, thus making the practicality of diversion of this U/ U for weapons purposes most unlikely. The significant feature of a gas core concept from a proliferation standpoint lies in the relatively low amount of fissile material in the system (core plus blanket) at any time.

The critical masses obtained in this study ranged from 40 to 400 kg of I - However, the critical inventory in the entire fuel circuit is of more interest to the reactor designer than is the critical mass. The critical in- entories corresponding to an external fuel volume of 339 ft are therefore shown in Fig. 14-3. Inventories for other external volumes may be computed from the relation...
