9.3 The most aggressive leachant (deionized water vs. synthetic sea water) will be identified by performing 24-hour (or longer) leaching measurements on both leachants, and the leachant which exhibits the lowest leach index (highest leach rate) will be used for the remaining tests.

1 O

9.4 Leach testing will be performed in accordance with the Branch Technical Position, appendix A.II.F, and ANS/ ANSI Procedure 16.1, and ACM-6300.

The cylinder will be immersed in a measured volume of water, which is changed at intervals of 2, 7, 24, 48, 72, 90, and 120 hours0.00139 days 0.0333 hours 1.984127e-4 weeks 4.566e-5 months . Upon removal of the cylinder (in accordance with j

ANSI /ANS 16.1, section 2.3) the leachant will be analyzed for Cesium-137, Strontium-90, and Plutonium-241 concentration.

Each

)

concentration is expressed as an "L" value for that leaching interval.

The "L" value is the logarithm of the inverse of the 4

i effective diffusivity for each isotope.

The "Leachability Index" is the arithmetic mean of the "L" values.

The Leachability Index, as calculated in accordance with ANS/ ANSI lf.1, should be greater than 6.0.

J TEST PROCEDURE FOR DEVELOPMENT OF PROCESS CONTROL PARAMETERS FOR CEMENT SOLIDIFICATION OF SLUDGE WASH LIQUIDS i

VVNS-TP 028 l

Rev, 0 1.0 SCOPE I

1.1 The objective of this overall testing criteria is to establish the windows for full scale production of the sludge wash cement waste form in which an acceptable product can be made.

This is based upon i

the require.nents stated in the NRC Technical position paper on Waste

{

Form Rev. 1 Section VI.

These windows include variances in the l

major chemical components of the simulated sludge wash liquid and the cement recipe enhancers.

Laboratory specimens, two inch square d

cubes, will be used to evaluated these windows, 4

i 1.2 The work will include the formulation of a series of individual simulated sludge wash liquids with single component variationc and then a series of individual solutions with multi variances which will be evaluated by a statistical grid (see attachment A),

i 1.3 The single variances will include determination of an acceptable range for sulfate, nitrate / nitrite ratio, organics and aluminum, 1.4 An acceptable range for pH, total solids, phosphate and borate will i \\

be evaluated with the use of a multi variance determination.

The cement recipe enchancers to be evaluated will be water to cement ratio, calcium nitrate four hydrate, antifoam, sodium silicate and mix time and will also be determined by this multi variance j

approach.

1.5 After an appropriate curing period, the laboratory specimens will be subjected to compressive strength testing.

This testing will provide data on the influence of variations of the chemical composition of the sludge wash liquid and the recipe enhancers on j

the compressive strength of the cement vaste form.

2.0 DEFINITIONS AND ABBREVIATIONS 2.1 Definitions Cement-Dry Portland Type I cement in accordance with ASTM Standard C-150-85.

5.0 GENERAL INFORMATION 5.1 The testing of compressive strength on cement waste form specimens will be used to evaluate the process control parameters and is considered an acceptable criteria on the overall performance of the product as indicated in the NRC Technical Position Rev 1 section VI.

The mean compressive strength indicated by any one process

control parameter should yield at least five hundred psi after an i

appropriate curing period. Although cement-products nominally 4

achieve seventy five percent of their_ strength in approximately twenty eight days, it has been.~ decided by convention that a curing

[

period of seven days for laboratory specimens will allow the L

specimens to gather sufficient strength in order to be evaluated.

This curing process for process control ~ parameter cement specimens-l

-involves the specimens-be placed in an oven or environmental chamber j

and sealed individual or in a group-in plastic bags _for sixty one-j hours +/ eight hours at eighty eight degrees. celsius +/- two degrees and then a pentameter test is performed on each specimen to 4

see if the cement has set.

The remain time period, for a total of seven days +/ eight hours, the specimens will cured at twenty-degrees celsius +/ five degrees.

At this point the specimen will be tested for compressive strength by_ the applicable. steps of ACM.

l 4701.

l' The results from this testing will provide a basis on the effects of a

l variances in the full scale process as indicated above and if these variances and at what extreme will still produce an acceptable j

product defined by the NRC Technical Draft on Waste Form Rev 1.

1,1 This work is required to demonstrate the stability of the " nominal"

{

vaste form recipe developed under Test Request VVNS-TRQ 026.

Characteristics which will be tested are required by 10 CFR 61, Code j

of Federal Regulations. Title 10 " Licensing Requirements for Land i

Disposal of Radioactive Waste," and the USNRC Branch Technical i.

Position on Waste Form, Revision 1, dated January, 1991.

1.2 Work will be performed using full scale square drums which were j

processed using a simulant representing the actual waste liquid, and the " nominal" recipe for cement addition and recipe enhancers.

The full scale drums will be processed under SIP 91-1.

1.3 This work is required by the Branch Technical Position, Appendix A.II.I.

1.4 Testing will be performed in accordance with' WVNS-TP-030, to be issued by Analytical and Process Chemistry, and WVNS-TPL 70-011.

1.5 Test results will be documented in a Test Summary Report (WVNS TRS-030), to be issued by the Cognizant Test Engineer in accordance with EP-11-003.

4 2.0 OEJECTIVES 2.1 After curing for a time determined by WVNS-TP 026, but in no case less than 28 days, approximately five (5) drums will be core-drilled to obtain 3" diameter X 6" long cylindrical samples.

A total of twenty-two (22) samples will be obtained.

i l

2.2 Cores will be obtained from various locations in the drums ( top, middle, bottom locations) to demonstrate the homogenous-nature of the waste form.

Locations will be recorded on SOP-70-44, Attachment D.

2.3 Ten (10) of the samples will.be evaluated for compressive strength per ASTM Standard C 39 and QIP 27.

WVNS-TRQ 030 Rev. O

(g 2.4 Twelve (12) of the samples will be immersed in either deionized

. (,,/

water or synthetic sea water for a minimum of 90 days.

After 90 i

days' immersion, three (3) of the samples will be evaluated for compressive strength per ASTM Standard C-39 and QIP 27.

Post-i immersion mean compressive strength shall be at least 75 percent of the pre-immersion mean compressive strength as determined by section l

2.3 above, and at least 500 PSI.

If the post immersion mean compressive strength is less than 75 percent of phe pre immersion mean compressive strength, but not less than 500 PSI, the immersion testing interval shall be increased to a minimum of 180 days.

The remaining samples will then be evaluated for compressive strength at intervals of 120, 150, and 180 days of immersion to establish that j

the compressive strengths level off and do not continue to decline l

with time.

i l

2.4.1 The immersion liquid, either deionized water or synthetic sea i

water, will be determined in advance of this test as part of the Leach Testing being conducted in accordance with 1
