available power, 320 megawatts come from the core and 130 megawatts 
of thermal power from the thorium blanket. The core will be processed 
at the rate of 2% per day, which gives, on the average, a 30 day 
cooling period. The blanket will be processed at the rate of 0.5% 
per day, providing a cooling period of about 180 days. 
Fission Product Wastes 
Wastes from Individual Reactor: To get an idea of the total 
amount of radioactivity produced by each reactor over a period of 
years it is assumed that the wastes from each power reactor are 
accumulated in a localized volume. 
Table 1 lists the significant fission products, including 
daughter products, produced daily in processing the irradiated 
fuel and blanket. Chains of the daughter products have been con- 
sidered as having 3 members; some are actually longer. Gaseous 
fission products have been disregarded as have isotopes less active 
than 10 curies and radioactivity produced by neutron capture. In 
the table, calculated activities are listed for these fission pro- 
ducts in the first 4 columms. The 3 right hand columns show the 
calculated equilibrium levels at the end of 10 years, based on the 
processing plant output accumulating day by day for 10 years. The 
total equilibrium activity is about 625 megacuries (625,000,000 curies) 
from each reactor.
