Describe how the sub-region of Region 1 which can presently store fuel up j
to 3.6 weight percent U-235 with no physical restrictions will be i
distinguished and separated from the sub-region of Region 1 which will j
store fuel with enrichnents higher than 3.6 weight percent in a 3 cut of l
4 configuration.

In order to prevent fuel loading errors in spent fv:1 pools with storage i
configuration rrstrictions, the staff has previously requested physical j
blockage of storage locations which are prohibited from containing any l
fuel.
Please discuss the acceptability of physically blocking the 4th f
cell in each 3 out of 4 cell array in Region 1 rather than relying solely on administrative procedures to prevent misleadings, i
