hCS CliE mm T.'il Certain experirental measurements are important to the selection of a suitable process icr cleaning r-the contaminated water a T."I with minimal risk to safety anc the publ:c.
The goals of the clean-up process are removal from the water of (1) ces:ur, (2) strontium, (3) iodine, and (') possibly other rac20 isotopes so that the product water meets the specifications (of 10 CFR-part 20) for release to the environment.
A sample cf water as representative as possible of the larger quantity of highly contaminated water will be required.
Because of the high radiation level the experi-ments will have to be car-ied out in a hot cell facility.
The following experiments are suggestec:
1.
"easure distribu. ion coefficients (Kd) between the water and selected r
absorbents (such as organic ion exchange resins, neolites, and charcoal) icr cesium, stront:um. iodine, and other isc:or,es as appropriate.
The purpose is to verify the benavlor of the particular chemical system as 1: exists on site.
2.
Make sirilar measurements after adjusting the water concosition to reoresent better the range cf compositions expected, or to cause favor-able changes in chemical properties, if necessary.
3.
Carry out small scale column tests with promising absorbent systems to
.ertfy multi-stage performance.
e.
' ' ' practical, extend column tests to two or more columns in series to determine maximum DF attainable.
This could be a miniature version of an actual clean-up system.
The results of these experimerts will permit the select 2cn of processes parti-cularly suited to the goals of the clean-up operation, and will provide core con-
- 1dence in their ultimate success.
