Docket 70 1257  !

Subject:

Siemens Power Corporation Request Dated May 22, 1997, with I supplementary information submitted July 15. 1997, to amend .

License No. SNM-1227. Docket No. 70-1257.  !

1. Because the activity has been analyzed for 3.5 gallon pails, modify your f amendment request as follows: Add a new entry to Table I-4.1 for 3.5  !

gallons or less containers with the following criticality controls: i VOL FNA CCM. MCU. ARA and SPA. Delete the use of FNA for the 5 gallon containers in your request.  !

f

2. Because the activity has been analyzed at 7.0 wt% H O2 and the U0 -H 2 2O i becomes visibly wet at 7.0 wt% H 2 0 and thus administrative controls i

! will be used to keep the H 2O wt% at or below 7.0 wt% modify your j l amendment.recuest as follows: Add to the " Discussion of any special l l controls usec/ additional explanation of control type" in Table I-4.1 for i 3.5 gallons or less containers the following condition: Containers will I never be visibly wet which means that the H2 O wt% will be less than or equal to 7.0. ,

I i

3. Describe the four steps in the activity: -(1) describe the normal  ;

filling process of the pails with UO powder 2 / pellets including the )

condition of storage at the filling site as a single tier array, (2)  !

describe the normal on-site transportation of the pails as two pallets i l (4 pails on each pallet C-to-C) on a forklift. (3) describe the normal i I storage of pails as in.a single tier array, and (4) describe the normal loading of pails into shipping casks as three stacks of 3 pails high j l' centered on 25"x25" steel pallets and must be attended until loaded into the overpack.

4. Describe the process of loading the pails with the U02 powde' cr pellets. Provide details so that we can determine that the criticality

! safety basis for storage encompasses the loading activity from the point l of filling the bags in the pail, to closing the lid of the ) ail, to placement of the pail on a pallet to storing the pail at tie filling

! site until transporting the pail to the storage area.

5. Why did you use a UO density of 2.0 g/cc in your analysis instead of thestandard10.96gicc? ,

i

6. Why did you use 7.0 wt% H 2 O and a volume fraction H2 O of 0.15054 in your analysis? ,

7. Why did you use the density of regular-concrete to be 1.0 g/cc instead l of the standard 2.3 g/cc? l

8. Why did you use the volume fraction of interspersed H2 0 to be 1.0e-6 instead of 1.0? i

9. What were your results (k-effective and sigma values) for the four L

situations in this activity: baseline (single pail with reflectors).

on-site transport (two 2x2-pail pallets with reflectors), storage 1 (infinite array with reflectors), loading into shipping casks (three 1x3-pail pallets with reflectors)?
