v M 3.0 DISCUSSION

lI

.,j i The type of waste covered by this document is bead ion exchange p  : resin mixed with powdered resin up to a 28 wot weight percent of f powdered resin. In order to ensure that the contents of the jJ f liners to be processed fall within the acceptable range with j! (. respect to the parameters, samples of the liner contents must be gp analyzed prior to solidification. Analysis includes pH, deter-

1; gents, a visual determination of oil content an$ an isotopic

.'] analysis.

$) 7.0 PROCEDURE d

l} NOTE:

Data taken as instructed in this section shall be i recorded on the attached Waste Solidification Data-

[ Sheet, Attachment A.

.e

, 3- 7.1 Chemical Analysis and Pretreatment

.,L' 7.1.1 EXAMINE the sample for evidence of detergents. If large quantities of detergents are present, the J' sample should be treated vnh an anti-foaming agent. The quantity of anti-foaming agent required 1

'73 I-( shall be recorded on Attachment A.

i# 7.1.2 EXAMINE the surface of the sample for any signs of

'b oil. If a measurable quantity of oil exists, y

determine the volume and record it as a percent of

  • 9 the total sample volume, otherwise note "none" or y

"less than one percent" (1%) by volume. If the p

c.J quantity of' oil is greater than 11 by volume, the oil shall be reduced to less than 1% by skimming

'( prior to recording.

7.1.3 MEASURE the pH of the sample and record.

.1' NOTE: If necessary, adjust the pH to greater J

than 4 using 50 weight percent sodium hydroxide solution. The quantity of sodium hydroxide added shall be recorded on Attachment A.

7.1.4 PERFORM an isotopic analysis of an appropriate

(

aliquot of the sample.

7.2.5 After sufficient mixing (2 minutes after all

.i cement and anhydrous sodium metasilicate have been added) so that a homogeneous mixture is obtained, allow the waste to CURE for a minimum of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

g 7.3 Solidification Acceptability

' The following criteria define an acceptable solidification process and process parameters.-

fI ( 7.3.1 The sample solidifications are considered acceptable 1

1 if there is no visual or drainable free water.

'i 7.3.2

The sample solidifications are considered acceptable i if upon visual inspection the waste appears that i it would hold its shape if removed from the beaker and it resists penetration.

q 7.4 Solidification Unacceptability 1 l 7.4.1 If a test sample fails to provide acceptable i

1 t

solidification, perform the following steps:

a. Mix egual volumes of dry cement and water to a

ensure that the problem is not a bad batch of

, cement.

' t j

b. Add additional caustic solution to raise the pH above S.

i

c. If the waste is only partially solidified, use lower waste to cement and additive ratios.

Using the recommended quantities of cement i ,

and anhydrous sodium metasilicate, reduce the sample weight by 21.7 gas (* 25 al) and the water weight by 7.5 grams.
