REQUEST FOR ADDITIONAL INFORMATION

Dear Mr. Kuehn:

As part of the decommissioning of the Saxton Nuclear Experimental Facility (SNEF), various facility components will be shipped off site for disposal as radioactive waste. To ensure that shipments of radioactive waste meet the requirements of the regulations in 10 CFR Part 61, the staff has reviewed information on the Saxton docket related to the classification of radioactive waste. During our review, questions have arisen for which we require additional information and clarification.. Please provide responses to the enclosed request for additional information within 60 days of the date of this letter. Following receipt of the additional information, we will continue our evaluation.

If you have any questions regarding this review, please contact me at (301) 415-1127.

Sincerely, ORIGINAL SIGNED BY:

h RE*aUEST FOR ADDITIONAL INFORMATION SAXTON NUCLEAR EXPERIMENTAL FACILITY i

DOCKET NO. 50-146 General Comment 1)

Can SNEC confirm that the lower core guide blocks (guide blocks) in the reactor vessel are the only Greater Than Class C (GTCC) waste? Explain. (See questions 3 and 4 below.)

l Specific Comments

{

Comments based on the "Saxton Facility Reactor Vessel, Internals, Ex-Vessel Lead, Structural Steel and Reactor Compartment Concrete Shield Wall Radionuclide Inventory" dated December 1995 2)

Section 3 - The neutron activation analyses assumed various fuel configurations to reflect the use of uranium oxide and mixed oxide fuels. Are these simplifying assumptions conservative in terms of overestimating the concentrations of nuclides l

important for waste classification?

3)

Section 7.3.1 - This report stated that the guide blocks are GTCC waste if classified individually, but because the guide blocks are permanently bolted to the lower core plate (plate), the guide blocks and the plate can be blended, and that the blend of guide blocks and the plate is within the Class C waste limits. Provide a l

clear picture or diagram that illustrates the bolted connection between the lower core guide blocks and the lower core plate.

Comments based on the "SNEC Site Characterization Report" dated 1996 4)

Section 4.2.10 - Justify blending the pipe sections that are individually GTCC with other piping systems. Guidance for averaging concentrations in homogeneous l

waste types is presented in Section 3.1 of the " Branch Technical Position on Concentration Averaging and Encapsulation," January 17,1995.

5)

Table 4 Identify the waste class of the items listed as "To Be Detcrmined" (TBD) if these items have been evaluated and classed.
