Dear Sir:

Three Mile Island Nuclear Station, l' 't II (TMI-2) Operating License No. " -73 Docket No. 50-32D Evaluation of EPICOR II Wastes The EPICOR II Radwaste System continues te process TMI-II Auxiliary and Fuel Handling Buildings contaminated water. The System has performed extremely sell decontaminating water well below cleanliness criteria. This performance has allowed using this processed water for decontamination purposes, and other transfer opera-tions, with minimal ALARA concerns. As of July 1, 1980, 365,055 gallons have been processed with 109,492 gallons remaining. A summary report is included as Attachment No. 1. A detailed evaluation of System performance is the subject of another report being assembled. This lettei is forwarded in response to NRC letter NRC/TMI-80-87, dated May 15, 1980. Water cleanup has resulted in the generation of sixty-four (64) spent resin liners as of July 1, 1980. These.. wastes contain contaminants, including fission products and chemicals removed from the water. This letter forwards information related to, and a discussion of, evaluations conducted to determine the condition of these wastes. Spent resin liners removed from the EPICOR II Radwaste System are placed in Waste Staging Facflities until final disposition. These facilities are massive concrete structures all but precluding access to the liners. A sealed fifteen (15) ton concr,ete cap over each liner staging cell provide liners protection from environ-mental conditions and essentially eliminates access by unauthorized personnel. The facility provides shielding allowing personnel to work alongside and on top of the cells containing liners without radiation problems. This facility has well demon-strated the ability to satisfy stringent ALARA requirements. Attachment No. 2 provides a layout of the protective barriers associated. with liner retention at Three Mile Island (TMI). This is a general layout presentation: should details be necessary, they can be provided upon request. 001 5 THIS DOCUMENT CONTAINS f// POOR QUAU1Y PAGES-Metropohtan Edison Company is a Member of the General Pubhc Utihtres System 8007140 ssa,

s. The retention of spent resin liners at T?E requires all necessary precautions to be taken to insure the fission products are contained until final disposition. The Commission's Memorandum and Order dated October 16, 1979, directed Metropolitan Edison to expeditiously solidify EPICOR II wastes. Extensive efforts are in progress to comply with this Order. This letter does not address the status of this solidification effort. Solidification will be the subject of separate correspondence as the results of conclusive studies and tests are obtained. This letter addresses the liners as they presently exist, in a dewatered state. Attachment No. 3 provides a tabulated summary of pertinent data for all liners. Evaluating EPICOR II liners and resins for long term stability was conducted prior to placing the System in service. A more exhausive study is in progress to document the projected. longevity of these containers without detrimentally altering the safe containment of fission products. Attachment No. 4 documents the background of this evaluation and provides a detailed discussion of items included. Prelimi-nary analysis indicates, under postulated worst case conditions, the resin and liner package provides safe retention of fission products for several years. A more precise definition of this condition is in progress which includes radio-lytical as well as chemical /metalurgic'al effects. When available, the details of this evaluation will be made available. The NRC letter of May 15th requested information relative to the liners and resins in use. Attachment No. 4 contains much of this information. Attachments 5, 6, and 7 provide drawings of both the 4x4 and 6x6 liners, and the painting specification used on the liner interior. Please note the liners have recently undergone a minor modification to allow installation of an air bubbler for redundant level ind! cation. The drawings are being updated to include these changes. These will be forwarded as available; however, this alteration has little to no impact on the long term integrity of the liners. Should additional information not forwarded or highlighted in this letter be required, please contact me or my staff. Sincerely, f' . K. Hovey b Director, TMI-II GKH:RJM: dad Attachments (7) cc: T.

Page 3 of 14 I. Introduction The Epicor II Radwaste System is designed and operated to remove fission products from a mobile medium, water, and transfer these products to a fixed medium, resin. In addi-tion, this system concentrates radioactive material so that its overall management and final disposal is enhanced. Once ~:- contained in resin liners it is necessary to determine the long term stability of this package to properly contain fis-sion. products. To review this topic, both the integrity of the liner and the stability of the resin media.over a period of time must be. evaluated. This evaluation is divided into two parts La order to focus on the retention of fission pro-ducts on the resin bead and secondly the retention of fis-sion products by the liner.itself., II. General Assumptions The assumptions governing this Epicor II liner and resin evaluation are: o The liners exist in a dewatered* state when they are removed from service. o The liners are retained in the Interim and/or Waste Staging Facility. o The resins are not solidified.. 1

Dewatered conditions are well documented and definsd in the'./ ~

Dewatering Program Report (R. Wilson letter dtd. 11/30/80 to J. Collins, NRC), o The evaluation is to include the full range of time spans from Onmediate to infinite conditions. This i would cover worst case parameters regardless whether they occur bnmediately upon removal from service or j at infinite time. o Dispersal of fission products outside the container, 'should it ever occur, and its effects, are not includ-ed. It should be noted that resins in a dewatered state are relatively immobile by themselves. III. Conclusion The prelimindry evaluation indicates under postulated worst case. conditions, the resin and liner package provide l j safe retention of - fission products. for several years.,.4 t .u.

Page 5 of 14 A. Introduction The integrity of Epicor II Spent Resin Liners must be analyzed in terms of the effects of the environment both external and internal to the liners. With the liners being retained in the Waste Staging Facilities, external environmental conditions are reasonably stable & are essentially of no consequence. The use of resins and associated contaminants deposited on the resins, re-quire careful analysis with regard to internal conditions. The deposited contaminants result in both chemical and radiolytical factors which must be accounted for. The de-gree and time of metallurgical reaction dependence must be fully evaluated to determine the assurance of providing a proper container for containing fission products within the liner. B.

Background

The Epicor II Radwaste System was designed and con-structed bnmediately following the TMI-II March 28th, 1979 accident. This system was required to clean radioactive waste water with activity ranging from 1.0 to 100 micro-curies per cubic centimeter Cyc/cc). The system was devel-oped on an emergency basis by a large group of on site and off site personnel both company cnd consultants. The severe-ly intense design stag 6 included repeated meetings with ven-dors as well.as presentations to Nuclear Regulatory Commis-sion (NRC) personnel to insure that a highly reliable,, wall" - ~~ designed, safe' system would.be installed that would clean the. contaminated water to satisfactory limits, producing a safe waste product, while accounting for ALARA requirements. Be-cause of the criticality of having this system available in an expeditious manner, comprehensive reports, documents, eval-uations and studies were not oroduced. However, correspond- ~ ence is'available to track the chronology of events and deci-sions pertinent to important issues. The design of the Epicor II Liners' was an iten that was carefully scrutinized by both on and off site company personnel and consultants. This review included such items as long term integrity and provisions for handling. The main item of inter-est pertinent to this evaluation is liner integrity. This was the subj ect of several meetings and. presentations during April, May and June 1979...The basic liner design is as shown in dwgs. BL-62579 for.a 4 x 4 (four. feet tall by four feet in diameter) (Attachment 5) and Epicor T-66000 for a 6~ x:6 (Attachment'6). These carbon-steel vessels are painted on both interior and ex-terior surfaces. Painting specifications, Plasite #7155 and Carboline (Phenoline 368 primer and finish)(Attachment ~ 7) pro-vide specifics of the type and method of interior paint appli-cation. j

....m,m m... y, Page 6 of 14 A metallurgical evaluation including experiences with this type of liner design concluded the liners would pro-vide. safe, reliable containment of fission products for at . least five years following removal from service. It was envisioned five years would provide sufficient time from removal from service,to shipment and burial of these wastes. ~ Since the burial facility provided the final long term con-tainment, the integrity beyond five (5) years was not eval-uated. There exists no regulations as to the design criter-ia of such liners so it was concluded the. design would sat- 'isfy criteria both at TMI and for final' disposition. Should the liner be required to act as containment for extended periods,. it was judged that more resistant materials might be required, however since that was not the case, it was not selected.- As discussed earlier,.due to the urgency of this type of evaluation, formal documen~tation d6e's not exist. Once Epicor II became operational on October 22nd, 1979, J it was determined that subsequent evaluation of the liner design would be conducted incorporating contaminant deposi-tion and other performance data in the analysis. After sev-eral months of experience, a more formal, comprehensive eval- -uation was commenced.co more precisely analyze conditions in the liner and how the liner would withstand this environment. The purpose of this review was to integrate chemical and met-i allurgical aspects with time so as to accurately define liner ' integrity. This evaluation is being performed.by the Process Support Group and the GPU Laboratory Materials Technology and' Chemistry Sections. C. Assumptions Some of the assumptions and/or variables included in this evaluation are:

l. Liner Internal Coating - The full range of liner paint

. conditions are considered. These include: The coating being fully intact; the coating partially failed; coating containing pin holes; or no coating. This range will include the worst case parameters.,

2. Seal - Once a liner-is removed ficm service.it is de.

watered and sealed with screwed cap fittings, and a' 55 gallon drum ring seal. 3 ' ~

3. Volume -- A 4 x 4 liner contains an average of 30ft 3 of resin while a 6 x 6 contains an, average of 110ft

4. Moisture Content - The moisture content in a dewatered liner are as defined in the Dewatering Study. (R. Wilson

5. Chemical Contaminants - Based upon sample results the minimum and maximum amount of chemicals depos-ited in each applicable liner type including items such as Sodium, Baron, Chlorides, Nitrates, Phos-phates, Sulphates, etc. is included.

6. Curies - Based upon sample results, the minimum and maximum amount of curies deposited in each specific liner is included.

7. Exterior Environment - Epicor II liners are retained in on site Waste Staging Facilities.

Moisture, temp-erature and other atmospheric conditions are included. D. Conclusions

1. Preliminary analysis indicates that the resin liner under the postulated worst case conditions including an initial defect in the coating would not perforate for several years.

2. The coating vendors indicate that in the absence of defects in the coating, the normal life for the coat-ing in the postulated environment would be similar to that for a coating subj ected to demineralized water, which is in excess of ten years.

3. Tests conducted by the-coating' vendors ^ indicate the coatings can withstand 1 x 109 rads dose with no ap-parent degradation.'

4. The precise worst case internal environment as it re-lates to time must be more closely determined for a closer definition of the corrosion rate.

aiiacnnent ** Page 9 of 14 A. Introduction The stability of the aaterials used in Epicor II - liners for water cleanup purposes must be analyzed in terms of radiolytical effects. The fission products deposited on the organic and inorganic materials re-sult in radiation exposure which accumulates with time. This integrated dose results in primary and secondary effects associated with the stability with which resins rotain mixed fission products, and the integrity of the liner itself. ^ B.

Background

The major radioisotope existing in the Auxiliary and Fuel Handling building waste waters im' ediately fol-m lowing the accident was iodine. The immediancy of clean-ing this water dictated designing the Epicor II process to remove this contaminant, among others. The prefilter in the system was specifically tailored for this purpose with a design loading of up to 2,500 curies. The design was relatively fixed by the middle of May, 1979, with shielding based upon 2,500 curie deposition. Realizing the half life of Iodine (specifically 131I) and the pro-jected availability of placing the system in operation, an evaluation was recommenced for contaminant-removal following the decay of iodine. A meeting held on July 13th.,1979, focused on alter-ing the system process design and reviewing ~the.results. bf i investigations completed.by various organizations. .It was during this *mesting' that ths limitationsi Associated witho f ei i '- each.lir..r was' determined. In particular, personnel from Epicor Inc. presented a proposal to alter the prefilter from being a prime Iodine remover to being a prime Cesium and Strontium remover. The number of curies that could be safely deposited on the prefilter was reviewed in some de-tail. .It was during this meeting, also attended by NRC personnel, that the radiation resistance of various types j of resins was. discussed. It was determined, based upon i specific selection of resins, that 1300 curies would not present any significant detrimental effects. In addition, 1300 curies in a 4 x 4 liner would provide several choices for shipping casks when shipment was required. Other proc-essing parameters would also be enhanced'.c. Th'is issue was,, investigated further with a second. meeting hdld onEJulyo'

n..

w 24th,1975.

This t second meetingi also attendea by NRC per ' -

c sonnel. confirmed that the curie volumes were satisfactory limits. (Prefilter 1,300 curies, Demineralizer K1, 500 curies and Demineralizer K-2, 20 curies.) This initial review indicated no substantial concern over the near term radiolyticci effects. As discussed in i Part I " Liner Chemical / Metallurgical Evaluation," formal i

fag $~E0of55 ~ ' ' documentation of this evaluation was not made during the early development stages of the system. After several months of operational experience, steps were taken to conduct a more exhaustive study. This study would formally document radiolytical effects and focus on primary and secondary actions in the liners integrated over time. This evaluation is being conducted by the Process Support and Radiological Engineering Groups. C. Conclusions

1. Preliminary analysis based on postulated worst case

~ conditions indicates that no significant areas of concern exist for several years fo.11owing removal from service. ~~

2. Curies deposited in liners are not homogenously distributed throughout the liner.

D. Dose Calculation The degree of rad'iation effect is almost directly relat-ed to the integrated dose received by resins. Since this is a critical parameter, this section-details some of the assump-tions and methodologies used in determining this value.

1. Assumptions:

Extremely conservative assumptions were used to cal-J culate the integrated dose.the resins are subj ected .a to. Some of'theie are w-

a. The maximum amount of curies are deposit"d on the minimum amount of resins.

b. No self shielding of resins occurs within a liner.

c. Where applicable, the energy of gammas is complete-ly absorbed by the section of resins which it is deposited on.

d. The dose received by c resin bead comes from a com-bination of radiation deposited on the bead itself as well as radiation from beads adjoining the.part-;.

2 icular beadtbeing analy' zed.> - - ~

2. Curies Deposited; The number of curies deposited per liner varies with each. liner. provides.a presentation of the number of liners of each type versus the curies deposited.

This display clearly shows the prefilters contain the vast majority of curies. The prefilters .2 s

y Paga 11 of 14 pose as the most severe situation and therefore the preliminary evaluation concentrates on these liners. The fission products removed by each' liner are documented in Batch Data Sheets. These sheets are not included in this report due to their volume. These documents, previously provid-ed to the NRC, allow calculating dose.due to spe- ~: cific or group types of radionuclides. The data 1: in these Batch Reports is summarized in Attachment 3. I

3. Curie Distribution' within a Liner:

The distribution of curie deposition throughout a liner is dependent.upon liner design, types of resins used, ' direction of " liquid flow, ' and how the resins are deposited within the bed. This single parameter provides a guidelines by which all associ-ated variables can be accounted for. Radiation surveys are taken as liners are lowered into Waste Staging Facilities. These surveys con-sist of radiation readings along side the length of a liner. Two circumferential points are taken 1800 apart from each other. These two points allow for_ determining if preferential side loading is oc-curring due to channeling, bypasses, or other intern-al hydraulic actions. 0 shows the fixed geometry of the radiation surve s. The. geometry of. the instrument shows that approximatelyv6.6' inches of. unshielded liner heighth is exposed to th.e meter's ion chamberiat any 'ne time. While! the surryh the liner is stopped every six * (6)y i's be + - o Ang taken, inches of downward travel to obtain and record survey instru-ment readings. Although the chamber sees some radia-tion other than the unshielded portion, the amount of radiation is considered of ILnited significance. Typical surveys for a' liner containing 1292 curies are included in Attachments 11 and 12. These surveys show that as the meter. window becomes more columnated (12.25 inches versus 9") the b~ ell shaped curve becomes tighter and more pronounced. In addition these surveys show that curies are not homogenously deposited throughout a liner. From this information, the curies deposited

E.' Resin Irradiation Data ae performance of resins when exposed to radiation is doc-om umented in many references readily available in the industry. No attempt will be made to list all pertinent documents. How-ever, because'the degree ~of resin resistance is dependent upon .yw M k hg, 'O, -.~.D NNN8 4* N"

Fiia~ii~;E 14 4 'its type, the individual references for the type of materials used in Epicor II liners is important, It is. generally accepted that inorganic resins are more stable when exposed to radiation than organic resins.

Also, as previously discussed, the prefilters contain the vast ma-

] jority of radionuclides removed from the water. From this ~ .information it was determined that the first eleven (11) pre-filters pose as the worst ca.se condition for resin irradiation effects. provides a tabulation of these first 1 prefilters'and the associated curies deposited. This attach-ment shows that only three (3) prefilters contain the greatest amount of curies. These liners pose as worst case conditions. To evaluate the radiation effects of Epicor Inc. resins, data was accumulated that addressdd the sp'ecific reaction ex-perienced by the resins in use. This data is provided in At-tachmene 13. Having established the worst case curic loading and ob-taining ' resin irradiation references, the stability of the resins were evaluated. F., Effects of Resin Irradiation These.are basically eight irradiation reactions which have been reviewed in this evaluation. These reactions were categorized according to effects on the resin matrix, physical alterations, and other safety concerns. They are: o Gas Generation o Safety of Nitrated Typ&'Resinst,

.'ca o

Scission of Functional Groups - o Scission of Polymeric Structure o Scission of Cross Linkage Bond o Agglomeration o Swelling / Shrinking o Discoloration Each area will be explored to provide preliminary results of the analysis:

1. Gas Generation-Primary effect:

Over the infinite life of a liner, under. postulated worst' case conditions, ths' maximum.in ~~ - crease of liner pressure due to-Gas Generation is 2 lbs. per square inch (psi). A hydrostatic test of a liner demonstrated that a liner can withstand up to 19 psi prior to breaching liner integrity. At that pressure a minor leakage point. developes at the top of the liner. There~is no indication that-this'will pose as a signifi-l cant problem. l li. 3 ,-v ,m

,e-

,m.,, a---

NagI$~b~o'f15 Secondary Effect: Possible generation of gases that would combine with residual moisture in the liner or the matrix of hydration of a resin bead could produce an acid. This acid might lower the pH of liner in-ternals resulting in more aggressive chemical attack on the paint and/or liner surface. Since the liner and resin design contains a buffer to-maintain the pH at 5.0 or higher, there fus no indication that this will pose as a significant problem over tha next sever-al years.

2. Safety of Nitrated Type Resins The Epicor II Radwaste System does not contain nitrated type resins nor is - there. s,ufficien.t,mnounts of nitrate contaminants in the waste water to shift resins to a nitrate form.

This is not a concern.

3. Scission of Functional Groups Primary Effect:

The loss of exchange capacity is not a problem since once taken out of service, additional ex-change capacity is not required. Even so, the resin in the liners is not exhausted chemically so a signifi-cant amount of capacity exists when removed from service. Secondary Effect: Radioisotopes could be.remobilized as a salt should functional groups complexed with radionuc-lides be broken from the main resin matrix. - Since no liners are exhausted when removed'from service, this extra capacity will refix any radionuclides back.into solid - i resin matrix.:h r ei x

4. Scission of Polyneric Structure Primary Effect:

Physical breakup of resins results in fines which will not cause any problems in Epicor II

liners, Secondary Effect:

The formation of reactive chemical species is based upon-resin types, contaminants deposit-j ed, and radiolysis. There is no indication that this will_ pose as a significant problem over the next several ) years. i 5.sScission>of' Cross Linkage Bond-c w ~ l The alteration of the porosity and/or ion exchange ca-pacity of an Epicor II liner is not a problem since the liners will not be placed back in service for water cleanup purposes. er e w N**hhe W

ATTACHMENT #4 Page 14 of 14

6. Agglomeration The agglomeration or joining of resin beads does not pose as a problem unless transfer of resin beads out of the liners is required.

This effect is related to dose and over the next several years it is.appar-ent that insufficient exposure to resins will occur to cause agglomeration. 7, Swelling / Shrinking Sufficient void space exists in Epicor II liners to eliminate this o a concern. With solidification, this issue would have to be addressed carefully..

8. Discoloration The change of the color of resins is of no consequence.
