Dear Mr. Standerfer:
Subject:
Seismic Design Criteria for Modified Containment Penetrations Y
The NRC staff has reviewed your request (reference 1) for deletion of the constraint of 20 ft.2 of modified penetrations between the reactor building i
and auxiliary / fuel handling buildings given in our November 5,1984 letter M
(reference 4). In our previous analyses the penetrations to the auxiliary and
,3 fuel handling buildings were not the limiting case. As discussed in the enclosure, if a total of 40 ft.2 of these penetrations were modified the offsite dose consequences of the modeled accident would remain a small portion E
of the limits in 10 CFR 100.
Thus the staff concurs with expanding the limit to 40 ft.a, Any additional modifications for which the potential offsite dose consequences
+
could be estimated to exceed a small portion of the 10 CFR 100 limits (references 5 and 6), however, will be evaluated on a case by case basis 3
(reference 2). -The staff will consider the nature of the modification, the
,o duration of the modification, and any restriction of activities while the-modificaticn is in place in addition to the potential offsite dose consequences.
s Sincerely, once4AL spS E 7
