A.4' HAZARD INDEX TABLES
A.68
The tables of hazard indices (A.4.la through A.4.9b) appear in the same format as those
for the radioactivity inventory (A.2) and heat generation rates (A.3).
The hazard index employed here is the amount of water (m 3 ) required to dilute the
quantity of a radionuclide present in one metric ton of spent fuel (MTHM) to drinking water
standards. Following the summation at the bottom of each table, a uranium ore index is also
shown. This is the ratio of the hazard index for the spent fuel to the hazard index (8.7
x 107 m 3 ) for the quantity of 0.2% U 30 8 uranium ore required to produce one metric
ton of 3% 235U fuel (see Section 3.4 for further discussion of these indices).
The total index for the fission products and activation products must be added to the
total index for the actinides to obtain the total spent fuel index.
