    1.0 SCOPE

    The purpose of this document is to provide guidance for the disposal of radioactive chemical waste to the 219-S Waste Handling Facility.

    This document is not intended to he a “yes” or “no” guideline. Chemicals that are listed as unsuitable may still be discharged to the system with proper controls and approvals. The chemicals entering the waste stream must also meet Tank Farm criteria.

    The lists of unsuitable chemicals were compiled from several sources. However, due to the extensive scope of this field, these lists should not be considered complete or conclusive.

    The effects of radiation on the materials are not addressed in this information

    2.0 BACKGROUND

    The 219-S Waste Handling Facility consists ofthree tanks (101, 102, and 104) which areused to store and treat the radioactive liquid waste from the 222-S Laboratory.

    Tanks 101 and 104 are the collection tanks. When a quantity of liquid has been collected in these tanks, the liquid is transferred to the 102 tank. The liquid waste is treated to meet Tank Farm specifications in tank 102 and then transferred to Tank Farms.

    Tank 101 collects the waste from the 11-A hot cells

    Tank 104 collects the waste from hood 16 in room 2B, and the ICP’s located in room I-J through the T-4 tunnel. The I-E-], 1-E-2, 1-F, and I-A hot cells feed the 104 tank through the T-7 and T-8 tunnel.

    CHEMICAL RESISTANCE GUIDE A word about our cliemlcal redstance gulde. 7he chemical resistance data provided hero and on the following pages has been assembled from a wide variety of sourcesinour industry. Thisintormalion is basodonpractical lield experience and actual laboratory testing conducted by the manufacturers 01 various plastic resins and finished prod- ucts. Keep in mind that this inlormation should only be used as a guideline lor recommendations and not a guarantee 01 chemical resistance. Some performance variations may be noticed between homopolymers and copolymers as well as emulsion and suspension type resins of the same general type. In addition. actual service conditions including tempera- ture, concentration and contaminants will affect variances in chemical resistance.

    In assembling the chemical resistance data presented here, several sources were checked. When conflicts were uncov- ered, we took aconservative approach and usedthe lowerof two or more ratings. In addition. special consideration was given to the material as supplied by a pariicularvendor; Le.. our polyethylene ratings arebasedon informationprovidedby tank manufacturers rather than pipe suppliers. This wasdone primarily because of the volume of tanks supplied as com- pared to polyethylene pipe.

    Plastics and elastomersin anattemptlomaketherscommen- dations more meaningful we have given the maximum recom- mended use temperature lor each plastic and elastomers in thespecificchemicals listed. Lacking complete datain many

    Cases we did leave thosa in question as blanks. Whero a material is unsuitable for a specilic chemical an "X' is used.

    Metals are rated as:

    A = Excellent B =Good, minor slfect C = Fair, needs lurther tests X = Unsuitable

    Tothe best of our knowledge the information mnlained in this publication is accurate. However, we do not assume any liability whatsoever lor the accuracy or mmpleteness of such information. Moreover, there is a need to reduce human exposure l o many materials to the lowest physical limits in view 01 possible long-term adverse effects. To the extent that any hazards may have been mentioned in this publication. we neilhersuggesl nor guarantee that such hazards are the only ones which exist. Final determination of the suitability of any inlormation or product for the use contemplated by any user, the manner of that use and whether there IS any infringement of patents, is the sole responsibility of the user. We recom- mend that anyoneintending to rely on any recommendationor to use any equipment, processing technique or material mentioned in this publication should satisfy themselves as to such suitability, and that they meet all applicable safety and health standards. We strongly recommend the user seek and adhere to manulaclurers or suppliers current instruct'onslor handling each material they use.

    USE OF THE CHEMICAL RESISTANCE TABLES

    The aggressive agents are classified alphabotically according to their most common designation. Further descriptions include trivial or mmmon names as well astradenames.

    I1seb~eralmncentralionsaregivenforaparlicularmaterial.lhe' physicaldatain general relate tothe pureproduct,lhatis 100% concentration.

    In listing the maximum use temperaturesfor each plastic type in a given chemical it can in general be asssumed that the resistance will be no worse at lower temperatures.

    HOW TO SELECT THE CORRECT MATERIAL: 1. Locate the specilic chemical in the system or found in the

    surrounding atmosphere using the alphabetical charl of chemicals.

    has always been to suggest the least costly material that will do the job.

    3. Where a materialor elastome rappearstobe marginal mm- pared to the requirements, we enmurage a call to our technical service group in Chino, California.

    EXAMPLES: I . Methylene chloride; in the tables PVDF or Teflon are the

    Carbon steel works well for chlorinated Hydrocarbons of this sort and that would be our choice unless there was another reason to justify the higher cost of the PVDF or Tellon.

    2. Sodium hypochlorite. 20% at 100°F. PVC is good to 140°F and is the least expensive of the malerials available.

    3. Nitric acid, 40% at 90°F; CPVC is recommended in the lables to 1OO'F at this concentration,
