WASTE MANAGEMENT OPERATIONS<br />

The selection was based on degree <strong>of</strong> development and amount <strong>of</strong> operating experience<br />

for the given service. Fluidized bed calcination has been used to calcine radioactive<br />

waste at the Idaho National Engineering Laboratory since 1963. This operating experience<br />

made it the obvious choice for the reference process to make a calcine waste form.<br />

However, there has been only very limited experience in coupling a fluidized bed calciner<br />

to a glass melter. Instead, spray calcination has been quite well developed for use with<br />

waste glass melters in the U.S. and in Germany, therefore it was selected for the reference<br />

vitrification process.<br />

Issue<br />

<strong>Waste</strong> Storage<br />

One commenter requested that the Statement should include interim storage facilities<br />

in the general description <strong>of</strong> the fuel cycle since it is apparent from the discussions in<br />

the Statement that these facilities will be built. (208-NRC)<br />

Response<br />

DOE agrees with the concept stated here. Interim storage facilities are described in<br />

Section 4.4 <strong>of</strong> this final Statement. The number and type <strong>of</strong> interim storage facilities that<br />

"will be built" depends on the fuel cycle that is implemented, processing mode chosen for<br />

the fuel cycle, and also on the timing <strong>of</strong> repository availability relative to treatment <strong>of</strong><br />

the wastes. For a discussion <strong>of</strong> storage requirements with a range <strong>of</strong> fuel cycle assumptions<br />

see Section 7.3 <strong>of</strong> the final Statement.<br />

Draft p. 2.1.3<br />

Issue<br />

The statement, "Storage can occur either at the reactor site or at an <strong>of</strong>fsite indepen-<br />

dent spent fuel storage facility (ISFSF) sometimes referred to as away from reactor (AFR)<br />

storage," is misleading. The fact that an ISFSF can be an at-reactor or an AFR spent fuel<br />

storage site was not made clear to the public in the draft Statement. (55)<br />

Response<br />

DOE agrees that the quoted sentence does not make clear to the public that spent fuel<br />

can be stored in an ISFSF, either at the reactor site or away from the reactor. DOE felt<br />

that the important point was that spent fuel can be stored either at the reactor or at an
