y MEMORANDUM FOR:
B. K. Grimes, Assistant Director for Engineering and Projects, D0R FROM:
G. W. Knighton, Chief, Environmental Evaluation Branch, D0R
SUBJECT:
ACCIDENT CONSIDERATIONS FOR TANK FARM INSTALLATION In anticipation of the need for significant volume of radioactive water tanks on site, we requested HMB to look at methods of assuring contain-ment of tank spills.
Their review has clearly indicated that the island is sufficiently permeable hat anything spilled will relatively quickly get to the river.
Recognizing this perability, they recorcend that the tankage should be put on firm footing and the surface surrounding the tankage can be two layers of asphalt with a seal coat between them and a seal coat on top.
The asphalt on the parking lots would not be adequate for supporting loaded tankage or containing liquid spills.
A dike will be required sufficiently high to contain the liquid volume of the tanks.
The area should be arranged so that there is a sump with a positive seal against leakage so that samples may be taken and material discharged from the As the tankage will be out-of-docrs, consideration must be given sump.
to rain run-off sampling and discharge.
If available, a temporary type building might be useful in eliminating the rain run-off.
Due to the significantly high level activity in the waste water presently stored in containment and in plant tankage, consideration might be given to processing any waste water through demineralizers prior to storing it in temporary tankage.
This would certainly reduce any impact of spills.
Thought should be given to filtering the offgas of these tanks rather than venting straight to the atmosphere.
