~ g ) Ways in which these failures can occur include: (a) Failure of EFW actuation circuit components common to both feedwater trains (e.g., ICS failures which interact with circuitry). (b) Preventive maintenance outages affecting one EFW pump coupled with component failures affecting either or both of the other EFW pumps. (c) Pump failures involving control circuit failures, mechanical failures, plugging of the suction strainers, or inadequate steam supply to the turbine-driven EFW pump. (d) Human errors involving misalignment of EFW system valves following testing or maintenance, failure to manually start EFW pumps in a timely manner according to proceduras if automatic actuation fails, failure to switch EFW pump suction to a secondary source of EFW before drawdown of the i l primary EFW source, and failure to take corrective action upon indication of EFW malfunction. i i As noted previously, the licensee's study of EFW system reliability identified no ac electric power dependencies which would cause EFW system failure in the l event of a loss of all ac power. The NRC staff's review of the licensee's 't Februtry 7,1980 submittal regarding the EFW reliability study has not yet i s been completed. Although the staff has expressed concern about potential l 9, steam admission valve failure resulting in a turbine overspeed trip in the i event of a loss of all ac power, there is reasonable assuranca that this l concern can be resolved to the staff's satisfaction so that such dependenc)1 (if it does exist) will be eliminated. 4 i l Failure to restart the main feedwater system can be caused by: i (a) Failure of actuation circuitry, r (b) Human failure involving failure to restart the system or failure to correct the fault (if correctable) which initiated the loss of feedwater event. (Discussed previously.)

Comments Tritium - Tritium values for Monitoring Wells 1, 4, 5, 7, 8 and the pond remained within the ranges previously reported. Monitoring Well 2 continued to show a decline in tritium concentrations while Monitoring Well 6 results indicated an ~ increase over previously reported values. Camma Scans - All gamma scans were normal. Observation Well Soil Core - Results from the soil cores obtained from OW-10 indicated normal tritium levels down to the 21-23 foot level. Higher than back-ground levels were noted at the 23-25 and 25-27 foot levels. " Brown Water" - Princeton Laboratory has completed its analysis (attached) of the " brown water" associated with Monitoring Well 3. Although these eaalyses do not specifically identify the causative agent of the discoloration, the following conclusions have been reached: (1) none of EPA's priority pollutants were found in the water (2) heavy metal concentrations a re well below toxic levels (3) organic constituents are natural degradation products of Icaves, wood fibers, humus, etc. (4) inorganic constituents are naturally occurring elements normally associated with dust and soil particles It is apparent that there are no toxic or potentially toxic components in this discolored water. Based on the extensive analysis performed on this water and the lack of any suggestion that it possesses any toxic properties, we feel it unnecessary to pursue this point any further. O

r ?g Co nclusions Based on our analyses to date we can only conclude that (1) the water solutions are substantially free of EPA's priority pollutants, ( 2) that the particulate matter in the samples are primarily those found in misance dust; i e. is characteristic of airborne suspended solids, and (3) that the organics in the particulate are probably the degradation products of natural organic mat ter, such as leaves, wood fibers, etc. Please call us if there are any questions regarding our work, and if there are tests we can perform that are likely to provide useful information.

T. Collins, Deputy Director U. S. Nuc lear Regulatory Commission c/o Three Mile Island Nuclear Station Middictown, Pennsylvania 17057
Dear Sir:
Three Mile Island Nuclear Station, Unit II (TMI-2) Operating License No. DPR-73 Docket No. 50-32D Evaluation of EPICOR II Wastes The EPICOR II Radwaste System continues to process TMI-II Auxiliary and Fuel Handling Buildings contaminated water. The System has performed extremely well elecontaminating 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 letter is forwarded in response to NRC letter NRC/T:1I-00-87, dated May 15, 1980. Water cleanup has resulted in the generation of sixty-four (64) spent resin liners as of July 1, 1980. These uastes 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 f rom the EPICOR II Radwaste System are placed in Waste Staging Facilities until final disposition. These facilities are massive concrete structures all but precluding access to the liners. A sealed fifteen (15) ton concrete 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 /!/ Ce &) 1 Myopohtan q d:sco Comeary is a Memter of the General Pubhc Ut.ht es System NG e I hG 3~a F-
~ 2 e The retention of spent resin liners at TMI 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. l 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 /metalurgical 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 I 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 indication. The drawings are being updated to include these changes. These will be forwarded as available; however, this alteration has little to no impact on tha 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, J.A . K.

P2ge 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 thin package to properly contain fis-sion products. To review this topic, both the integrity of the liner and the stability cf the resin media over a period of time must be evaluated. This evaluation is divided into j two parts in 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., I II. General Assumptions i 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. 4
Dewatered conditions are well documented and defined in the'..
Dewatering Program Report (R. "ilson letter dtd. 11/30/80 to J. Collins, NRC). t o The evaluation is to include the full range of time spans from immediate to infinite conditions. This would cover worst case parameters regardless whether they occur immediately upon removal from service or at infinite time. a e 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 preliminary evaluation indicates under postulated worst case conditions, the resin and liner package provide safe retention of fission products for several years..-,.

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 radiolvtical factors which must be accounted for. The de-gree a'nd 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 immediately 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 (qp/cc). The system was devel-oped on an emergency basis by a large group of on site and off site personnel both company and consultants. The severe-ly intense design stage includcd repeated meetings with ven-dors as well as presentations to Nuclear Regulatory Commis-sion (NRC) personnel to insure that a highly reliable, well~ 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 produced. 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. Tha 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.
-1 ...........vv v 2:32 6 of 14 0 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 documentation does not exist. Once Epicor II became operational on October 22nd, 1979, 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 to more precisely analyze conditions in the liner and how the liner would withstand this environment. The purpcse of this review was to integrate chemical and met-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 T'echnology and Chemistry Sections. C. Assumptions Some of the assumptions and/or variables included in this evaluation are:
1. 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 from 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 30f t 3
of resin while a 6 x 6 contains an. average of Il0ft
4. Moisture Content - The moisture content in a dewatered liner are as defined in the Dewaterirg Study. (R. Wilson
Page 7 ci la letter dtd. 11/30/80 to J. Collins, NRC)
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. Curie's - 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.

1 I n..nuumal v4 2 ?;3e ? of 14 i A. Introduction The stability of the materials 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 retain 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 immediately fol-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 :o 2,500 curies. The design I was relatively fixed by the niddle of May, 1979, with shielding based upon 2,500 carie depositicn. Realizing the half life of Iodine (spccifically 131I) and the pro-j ected availability of placiag the system in operation, an evaluation was recommenccd 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 investigations completed.by various organizations. .It was during this' meeting'that the limitations associated witha n i: '- each liner 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 of resins was discussed. It was determined, based upon 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'.. This issue was
1 investigated further with a 'second. meeting.hdld on> July su.
24th,1979. "This second meeting also attended by NRC per-sonnel. confirmed that the curie volumes were satisfactory limits. (Prefilter 1,300 curies, Demineralizer K1, 500 curies and Deminerali=cr K-2, 20 curies.) This initial review indicated no substantial concern over the near term radiolyt.'. cal effects. As discussed in Part I " Liner Chemical / Metallurgical Evaluation," fommal
p Page 10 of 14 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 anc. 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 Cticulation The d.: gree of rad'iation effect is almost directly~relat-ed to the :ntegrated 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-culate the integrated dose.the resins are subjected to. Some of'these are: 8*- s-
a. The maximum amount of curies are deposited 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 a 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 bendtbeing analyzed., a-s!<--
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 denosited. This display clearly shows the prefilters contain the vast majority of curies. The prefilters O
PagS~5i 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 in these Batch Reports is summarized in Attachment 3.
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 surveys. The geometry of the instrument shows that approximately;6.5' inches of unshielded liner heighth is exposed to the meter's icn chamberfat any one time. While'the su'rve liner is stopped every six '(6)y is be-ing taken, the 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 limited 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 bell shaped curve becomes tighter and more pronounced. In addition these surveys show that curies are not homogenously deposited throughout a liner. Frem this information, the curies deposited versus cubic feet of resin was. determined. no. 0.- E. Resin Irradiation Data The performance of resins when exposed to radiation is doc-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
p Page 12 of 14 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 case condition for resin irradiation effects. provides a tabulation of these first 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'edific reaction ex-perienced by the resins in use. This data is provided in At-tachment 13. Having established the worst case curie 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 cealuation. These reactions were categorized according to effects on the resin matrix, physical alterations, and other safety concerns. They are: o Gas Generation Safety of Nitrated Typ6' Resins t - .1., 5 o Scission of Functional Groups o 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,:the 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-cant problem.
I ? Page 12 ef la 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 i an acid. This acid might lower the pH of liner in-j 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 is no indication that this will pose as a significant problem over the 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.ufficient, amounts 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. Cecer.dary 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 resin matrix. ' i-mn
4. Scission of Polyncric 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-ed, and radiolysis. There is no indication that this will pose as a significant problem over the next several years.
5. Scission.>of Cross Linkage. Bond-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.

.~ ATTACICEiT (14 Page la 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 ye'ars 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 as 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.

THINNERS The fotfowing thinners are recommended - the amounts required wi!! vary depending on air and surface temper-atures and application equipment. 3: is recommendcd that the amount of thinner included on e~ach order amount to approximately 20% of the coating cider. This thinner may be used for <!eaning equipment as well. PLASITE NO. 71 THINNER is a medium fast thinner and is to be used under most conditions. PLASITE NO. 72 THINNER is a relatively slow thinner and must be force cured when coating is used in Zone A appli. cations. It is an aid to force curing and eliminating solvent popping and improves flow.out of coating. PRIMERS ELA51TE NO. 7155 does 'not require a primer in ' Zone A service. If a shop primer or a primer to hold surface is required on large fabrications use No. 7155NP primer at 3 mils with topcoat of 6 mils No. 7155.

Plasite Bulletin M.7NP. -e CURING
1. Normally polymerization and curing will take place in 4 to 7 days at 70* F. If temperature is in the range of 50 to 65* F. Force Curing is recommended as curing rate is considerably lower at these temperatures.

2. Force Curing is recommended during cold weather, for enclosed tards or when coated surface is to be immened before 4 to 5 day room temperature ruring wi!! take placa.

3. Force Curich at elevated temperature does increase resistance to certain exposures, therefore when exposur Force Curing is recommended to obtain maximum resistance.

4. Beuv are (Isted a few curing schedules that may be used for time and work planning. Prior _ to raising the metal to the forte curing temperature it is necessary that an Air Dry time of 1% to 3 hours at temperatures from 70* F. to 100* F.
be allowed. After the air dry period has elapsed the temperature should be raised approximately 40* F. In increments of 30 minuies until the desired force curing temperatures are reached. DO NOT FORCE C11RE Above 100* F until final dry film is obtained. M._E_TA.l. TE_%P.ER.A_TUREr - _e CURING TIME-' - METAL.
