Shielded Annular Tanks
1. Misconstruction
1. Physical Verification
a. Annulus >3"
a. Verified as < 3"
b. Insufficient Shielding
b. Verified by TES to meet
design criteria.
2. Annulus Bulges
2. Significant bulging not
credible since tanks are
vented and certified to meet
pressurization from vacuum
transfers and low pressure
diaphragm pump.
Reference Appendix O for
tank certification.
3. Loss of Shielding
3. Materials encased in
stainless steel, which is
observed to be intact with
no corrosion.
4. Seismic Activity
4. Tanks are neutronically
isolated.
5. Overbatching to 300 g/l.
5. Tanks are limited to 150
g/l. Liquids required to be
characterized as less than
150 g/l before introduced
into tanks D-240 1 A/B/C/D
and the CWTS process.
6. Precipitation in tanks
6a. Caustic liquid not

accepted unless receiving
tank is empty and isolated
from other tanks.
6b. Inlet valve to tanks D-
2401 A/B/CID to be closed
when greater than four liters
of caustic is collected or
stored in any glovebox or
room which drains to CDS
"A". Liquid may be drained
into CDS "A" per 6a.
