WASTE MANAGEMENT OPERATIONS<br />

are now presented on the isotopes present in the decommisioning wastes from FRPs and<br />

MOX-FFPs and on the quantities released to the environment as a result <strong>of</strong> the decommissoning<br />

activities.<br />

Draft Appendix D<br />

Issue<br />

The 1,000 year storage and surveillance assumptions used in the calculations are in<br />

conflict with proposed Criteria for <strong>Radioactive</strong> <strong>Waste</strong>s (43 F.R. 53262 et seq., November 15,<br />

1978) developed by EPA. The appendix should be revised using the proposed period <strong>of</strong> storage<br />

and surveillance <strong>of</strong> no more than 100 years. (113-EPA)<br />

Response<br />

Two decommissioning alternatives were analyzed for each <strong>of</strong> the three basic fuel cycle<br />

facilities considered in the Statement. The alternatives were selected to show the possible<br />

range <strong>of</strong> environmental effects from decommissiong activities. The alternatives considered<br />

are permitted under current regulations, although it is recognized that future regulatory<br />

activities by NRC, EPA, and state agencies could significantly impact the choice for decom-<br />

missioning alternatives at a particular facility.<br />

The Statement recognizes that hardened safe storage <strong>of</strong> facilities, such as an FRP or<br />

MOX-FFP, that contain significant quantities <strong>of</strong> long-lived radionuclide would have to be<br />

followed at some time by final decommissioning activities that would remove residual radio-<br />

activity from the site and permit final termination <strong>of</strong> the facility license. A variety<br />

<strong>of</strong> factors would determine the length <strong>of</strong> time that a specific facility would remain in<br />

hardened safe storage. The period <strong>of</strong> 1,000 years was selected as a conservative upper<br />

bound. It should also be noted that because <strong>of</strong> uncertainties surrounding the surveillance<br />

and maintenance <strong>of</strong> decommissioned facilities for long periods <strong>of</strong> time, immediate dismantle-<br />

ment was selected as the reference decommissioning alternative for the MOX-FFP. Dismantle-<br />

ment after 30 years <strong>of</strong> safe storage was selected as the reference mode for the FRP (see<br />

final Section 4.6).<br />

DOE/ET-0028, Section 8<br />

Issue<br />

The preliminary information <strong>of</strong>fered by the DOE in Section 8.0 <strong>of</strong> the back-up document<br />

DOE/ET-0028 is obsolete and does not accurately reflect the Pacific Norhtwest Laboratory<br />

studies <strong>of</strong>- decommisssioning for the NRC as stated on page 8.1. The NRC information should<br />

be properly referenced and the DOE should provide current estimates <strong>of</strong> the TRU wastes to be<br />

expected from all decommissioning activities. (208-NRC)
