Scenario specific
value obtained
from Annex B
Qi,l (MBq) is the
activity limit for
radionuclide Rni
if it were the
only
radionuclide to
be disposed of.
Where DC is the dose
constraint (microSv/yr) which
is specific to the scenario:
= DC / SDi
Numbers must remain
>0.
DC = 20 microSv/yr or 3000
microSv/yr for intrusion
scenarios
This is all waste
received to date
and could
include a future
amount
proposed to be
received to test
the remaining
capacity is
adequate for
that shipment
