3, 1.0 PURPOSE 3- 1.1 The purpose of the Process Control Program (PCP) for radwaste 3 solidification is to provide reasonable assurance and documentation

'! of the solidification of processed radioactive wastes as set forth

in 10CFR20, 10CFR61, 10CFR71, the RBS 3/4.11.3 Technical i Specification, Federal and State regulations, burial ground requirements, and other requirements governing the disposal of

, radioactive wastes.

3.0 RESPONSIBILITIES s

j 3.1 The RBS Radwaste Section shall be responsible for the implementation

of the PCP and adhere to compliance with RBS Technical Specification i 3/4.11.3 Ref. 2.15.

i '4.0 DEFINITIONS

} 4.1 Solidification - The conversion of wet wastes into a form that

• meets

! shipping and burial ground requirements.

4.2 Batch - A specified quantity of waste material requiring solidifica-i tion, any portion of which would have the same physical and chemical i characteristics as the whole.

I l 4.3 Waste Classification - The determination of waste class as outlined

} in 10CFR61 by radionuclide isotopic analysis and/or correlation with i measured nuclides.

Free Liquid - Any nonabsorbed liquid in a radwaste package. The 4.4 shipment of any free liquid in a package of radwaste is absolutely prohibited.

i

4.5 DAW - Dry Activated Waste.

4.6 CNSI - Chem-Nuclear Systems Inc.

-j 5.0 PROCEDURE 5.1 General Requirements I-5.1.1 As required by RBS Effluent Technical Specification

} 3/4.11.3, the PCP shall be used to verify the solidification 1 of at least one representative test sample from at least every tenth batch of each type of wet radioactive waste

' ;[ processed.

').

,i 5.1.2 For the purpose of the RBS PCP, a batch shall consist of a lJ particular amount of liquid wastes / sludges requiring 1 solidification (i.e., the amount of waste content within a j tank requiring solidification). If new material is added to 4 a tank's contents which is currently being processed, a new L,-

batch is created and further sampling must be performed li'i prior to solidification.

} 5.1.3 If any sanple fails to solidify, solidification of the batch l under test shall be suspended until such time as additional test samples can be obtained, alternative solidification

" parameters can be determined in accordance with the PCP and i]l t

, g a subsequent test verifies solidification. - Solidification

j of the batch may then be resume.d using the alternative j solidification parameters determined by the vendor PCP.

5.1.4 If the initial test sample from a batch of waste fails to 3 verify solidification, then representative test samples i shall be collected from each consecutive batch of the same

] type of waste until three (3) consecutive test specimens j demonstrate solidification using the alternate parameters of

} Step 6.1.3.

i '

5.1.5 For high activity wastes, where handling samples could result in personnel radiation exposures which are inconsis-t tent with ALARA principles, representative non-radioactive samples may be test solidified. These samples shall be as

~

- close to the actual waste and chemical properties as possi-i ble. Typical unexpended mixed bead resin may be used to i! simulate the spent bead resin.

. 5.1.7 All solidification and sampling activities inside a Radiation Controlled Area shall be conducted in accordance with the applicable Radiation Work Permit requirements

) (Reference 2.12).

i 5.2.2 Taking Samples j 5.2.2.1 A sample of the contents of the Waste Sludge Tank

! that flows into the vendor's fill head and any

! other wastes requiring solidification must be taken

in order to determine the actual process

formulation for solidification, any pretreatment of

the waste needed prior to solidification, and the J waste classification of the tank contents to be j solidified.

5.2.2.2 Sample sizes, as determined by the Radwaste Sec-

] tion, shall be compatible with the standard size

samples used for radioactivity and chemical analy-J sis.

~;

5.2.2.3 If the radioactivity levels are too high to permit

~ full size samples to be taken, then smaller samples shall be taken with the results corrected accord-ingly.

j 5.2.2.4 Sufficient sampling lead time of the vendor's fill t head allotted prior to the planned waste 2 solidification of a batch to allow adequate time to complete the required testing and verification of

solidification, as applicable.

?

. 5.2.2.5 The contents of the waste tank that is to be Ia solidified should be recirculated (mixed) prior to

.L sampling to ensure that a representative sample is f obtained.

'i? 5.2.2.6 Sampling of resins will be performed per Reference.

5.3 Chemical Analysis of Waste Samples I 5.3.1 Waste samples shall be analyzed for total dissolved solids,

'; pH and conductivity by the vendor. Oil content and gamma isotopic analysis will be performed by the Chemistry Depart-

? ment. Information shall be recorded on the Waste Solidi-j '

fication Data Sheet (Attachment 1).

I 5.5 Waste Conditioning j 5.5.1 Prior to the test sample solidification, the pH of the sample shall be adjusted to a range as specified by vendor's

>. PCP.

2 5.5.2 Should adjustment be necessary, the agent and quantity used shall be recorded on the Waste Solidification Data Sheet

$. 5.5.4 If reduction of the oil' content is impossible or impracti-o cal, solidification of the batch shall not be attempted using the Normal Solidification System, but shall be accom-J plished using a bulk processing method as described in the

,j . vendor's PCP at RBS.

5.6 Test Solidification

the amount of liquid transferred. Calculate the percent of i free liquid and record the date on the Waste Solidification j Data Sheet (Attachment 1).

5.7 Process Formulations i Prior to actual solidification of the waste to be solidified, i classification and acceptability for near-surface disposal shall be

determined. This will involve calculating the activity within the i- projected waste containers using the isotopic analysis determined in

Step 5.4.1, in the solidification formulas determined below.

'I 6.0 ACCEPTANCE CRITERIA i

6.1 Test Solidification Acceptability -

6.1.1 The test sample solidification will be considered acceptable fg from a free liquid standpoint if it is the lessor of either g 1% by volume or burial site limits.

6.1.2 The test sample solidification will be considered acceptable

[ from a solid mass standpoint (i.e., structural stability) if 1 it is evident from it's physical appearance that the solid-

! ified waste maintains its shape when removed from the j container.

6.1.3 If either or both of the above checks fail to meet . the 1 stated criteria, alternative solidification parameters must I

be determined according to vendor PCP SD-09-003 before

,l solidification can proceed, i.

'f 6.1.4 If the initial test solidification of a batch is unaccept-y able, then a representative sample shall be test solidified

on each subsequent batch of the same type of waste until j three consecutive test samples verify solidification using j the alternate parameters of Step 6.1.3.

6.1.5 If a test sample fails to provide acceptable solidification j of waste, mix equal volumes of dry cement and water to j ensure that the problem is not due to a bad batch of cement.
