WASTE MANAGEMENT OPERATIONS<br />

One commenter requested that some discussion be included describing the compositon <strong>of</strong><br />

a special train and the advantages and disadvantages resulting from its use. Is it a safer<br />

mode <strong>of</strong> transport? Does it have better safeguard features? (208-NRC)<br />

Response<br />

Special trains were assumed not to be used in the spent fuel transportation for this<br />

report. Increased safety by using special trains has not been demonstrated (Rhoads 1977).<br />

Disadvantages <strong>of</strong> special trains are their high cost. Details <strong>of</strong> cost aspects may be found<br />

in Section 6.2.1.6 <strong>of</strong> DOE/ET-0028. Sane discussion is given in final Section 3.2 on the<br />

effects <strong>of</strong> interim NRC safeguard rules for the shipment <strong>of</strong> spent fuel.<br />

Draft p. N.7<br />

Issue<br />

One commenter felt that the discussion in the draft Statement which pointed out that<br />

heat dissipation is a prime consideration in the shipment <strong>of</strong> spent fuel may be miscon-<br />

strued. The prime safety considerations are containment, shielding, and subcriticality.<br />

Heat dissipation is important to the performance <strong>of</strong> the other safety features. (208-NRC)<br />

Response<br />

Use <strong>of</strong> the word "prime" may indeed have been in error and "important" would have been<br />

a better choice.<br />

Decommissioning<br />

The discussion on decommissioning should draw clearer distinctions between decommis-<br />

sioning requirements for reactor plants and the other fuel cycle facilities (since neutron<br />

activation <strong>of</strong> equipment does not occur in the other facilities). What isotopes are <strong>of</strong><br />

interest at storage facilities? (181)<br />

Response<br />

The decommissioning section <strong>of</strong> the final Statement (Section 4.6) does not address<br />

reactor plants (since they are not a part <strong>of</strong> high-level or TRU management activities). Data
