Dear .s. Mayes:
This is in response to your recent letter to Acting Chairman Ahearne, which expressed your concern related to the chemical decontamination of Dresden Nuclear Power Station, Unit No.1.
We have been reviewing this project since Commonwealth Edison's in'tial decor ar.ination proposal on December 12, 1974. On December 9,1975, we issued a conditional authorization which allowed Cormonwealth Edison to ir.itiate the chemical decontatination subject to the completion of three i ems which would be resolved as follows:
1.
T.e testing program will be completed and the results submitted for t.e review and approval of the NRC staff prior. to performing the c r:?osed chemical cleaning.
2.
A pre-service inspection program for the primary coolant boundary will be formulated and submitted for NRC review and approval prior
- returning the reactor to service.
3.
A ;:st-cleani69 surveillance progran which includes additional s arveillance specimens and a specimen withdrawal and examination s:F.edule will be submitted for NRC review and approval prior to returning the reactor to service.
A co;y of our Safety Evaluation in support of these actions is enclosed for y:ur information.
Sir.:s :;r 1975 authorization Commonwealth Edison has completed its ma erials test program and construction of the necessary support facilities to carry out the project in a safe and environmentally acce;;able manner. Our review of the testing program and the facility cor.strue: ion is continuing and will be completed prior to the chemical clear.'n; that is currently scheduled for the first half of 1980.
The ce:cntaminatien process involves the circulation of a Dow Chemical C:r:n y cleaning solvent through the reactor primary cooling system.
The s:lvent, identified as'NS-1, has been developed to remove the thin,
-i;.1,. adherent, layer of highly radioactive oxide that has formed on ne i. side surfaces of the Dresden 1 primary cooling system.
i l

' 's.

- Ine s:1 vent will preferentially disscive the exide withou; significantly atta:<.ing the underlying base metal of the primary cooling system piping.
At.er removal of the uranium fuel, the solvent will be circulated through the primary coolant system fcr approximately 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> at about 250*F.
After circulation the solvent and the dissolved oxides will be drained frca the reactor to a waste treatment. facility located adjacent to the reacter.
Any remaining solvent will be cleaned from the reactor by rinsing with demineralized water.
The rinse water and solvent will be stored in the waste treatment facility storage tanks until processed to cencentrate and solidify the solvent and dissolved radioactive corresion products.
The decontaminatien will be carried out entirely within a closed system and all waste processing will be accocplished within a specially designed, earthc.uake proof, leak tight, building.
All transportation of radioactive wastes will be done in accordance with all applicable NRC and Department cf Tra sper:ation regulations.
Because of these precautiens, there will b e r.: increased hazard te the health anc safety of the citizens of Illinois er an degradation of the environment in Illinois.
Afte. ; recessing the ccncentrated was e solutien will be solidified in 55 galien drums using a precass developed by the Ocw Chemical Company for the sclidificatien of Icw level radioactive wastes.
This solidification prccess has been tested en the NS-1 selvent and produced a solid waste form that contained no free liquids.
The waste solidification precedures include a quality control process test en each barrel of waste to provide additional assu a.ce that the liquid waste has been properly solidified.
Af te solicificat.icn the.easte drums will be transpcrted by a cer:rt.ercial ra:i:a::ive waste carrier to a licensad solid was e burial grcund such as E sa::y, Nevada er Hanferd, '.lashingten.
These arid, desert sites have been s:ecifically selected f er the dispcsal of the Dresden waste to furt..e. assure th t there is no interaction of the waste with ground
.a:er.
Because thx waste is in a solid form, the ground water level is' appr:ximately 300 Ret below the surface, and the burial sites are i
located in remote, uninhabited locaticas, there is adequate assurance that the waste will remain isolated from potential pathways for exposure f :ks pc;ul stion.
The c:st cf the Dresden i decentaminatien has been estimated at 36 million dollars.
Much cf this ccst represents ene time developmen: costs which wcuit r.ot be incurred in subsequent reactor dacon:aminaticn at Dresden -l er c:ter nuclear facilities.
At this time there are no plans to decon-l ti ' a a the primary ccoling sys:em of c:her U. S. nuclear facilities, l
Ms. Jean Mayes,
however, preliminary estimates of the cost for decontamination currently operating U. S. reactors range from 1 million to 5 million dollars per redctor and would vary depending on the ertent of. modification required at a specific facility to perform the decontamination.
The decontamination of reactor primary cocling systems will reduce the radiatien exposure levels in the areas of these systers, thereby permit-ting graater access to the system for inspection, modifications, and repairs. These activities provide greater assurance of the continued safe operation of the reactor and are therefore in the best interest of the health and safety of the public.
Furthermore, the decontamination will reduce the occupational exposure of the individuals employed at Dresden.
With respect to requests for the preparation of an Environmental Impact Statement for the Dresden Unit 1 decontamination, the Nuclear Regulatory Cortission is fully committed to satisfying all requirements of the National Environmental Policy Act (NEPA).
Our regulations which implement the NEPA reouirements are contained in Title 10, Part 51.5, of the United States Code of Federal Regulations.
These regulations are in conformance with guidelines issued by the President's Council on Environmental Quality which ware in effect prior to July 30, 1979.
They identify the following types of actions for which NRC must prepare an environmental impact stat erent:
"(1) Issuance of a permit to construct a nuclear power reactor, testing f acility, or fuel reprocessing plant pursuant to Part 50 cf this chapter; (2) Issuance of a full pcwer or design capacity license to operate a nuclear poder reactor, testing f acility, or fuel reprocessing plant pursuant to Part 50 of this chapter; (3' Issuance of g permit to construct or a design capacity license to operate an isttopic enrichment plant pursuant to {50.22 of this chapter; (4) Issuance of a license to possess and use special nuclear material fcr processing and fuel fabrication, scrap recovery, or conversion cf uranium hexafluoride pursuant to Part 70 of this chapter; (5) Issuance of a license to possess and use source material for uranium milling or production of uranium hexafluoride pursuant to P ar: 40 of this chapter; (c) Issuance of a license authorizing commerical radioactive waste disposal by land burial pursuant to Parts 30, 40, and/or 70 of this chapter; l
l l
l 1
Ms. Jean Mayes.
(7) Conversion of a provisional operating license for a nuclear
- oser reactor, testing f acility or fuel reprocessing plant to a full poaer or design capacity license pursuant to Part 50 of this chapter where no final environmental impact statement has been previously prepared; (2) Issuance of a license to manufacture pursuant to Appendix M of Part 50 of this Chapter; (9) Amendments of Parts 30 and 40 of this chapter concerning the exemption from licensing and regulatory requirements of any equip-ment, device, commodity or other product containing byproduct material or source material; and (10) Any other action which the Commission determines is a rajor Commission action significantly affecting the quality of the human envi ronme nt. "
The Cernission is presently in the process of modifying our Environmental Prctection regulations to take into account, voluntarily, the regulations presul;ated by CEQ which became effective July 30, 1979. We have concluded that this action is not one of these actions requiring an environmental impact statement under current Commission regulations.
While our regulations do not require the preparation of an environmental impact statement, we are evaluating the environmental impact of the proposed acticn to determine whether an environmental impact statement should be precerad because of specific circumstances related to this particular acticn.
If it is. determined that an environmental iapact statement need not be prepared, a negative declaration and envircamental impact appraisal will be prepared in accordance with Sections 51.7 and 51.50(d) of our pro-cedures for environmental protection.
We will cocplete our review and issue the appropriate statement or appraisal prior to the Dresden decontamination.
With regard to your comments about the study done at Oak Ridge National Laboratory report in Science, June 30, 1979, Commorwealth Edison, the licensee for Dresden Unit 1, has agreed to dispose of the Dresden 1 waste at either Seatty, Nevada or Hanferd, Washington commercial low level waste burial sites.
These sites differ significantly in their geclogic and hydrologic characteristics from the Oak Ridge site where chelant-aided migration of radionuclides was observed.
Specifically, the Oak Ridge site, where migration occurrr.d, experiences very high precipitation and has a water table so shallow that it probably intersects the disposal pits and trenches during periods of heavy rain 1
l fall.
In addition, the Oak Ridge topography is hilly with steep slopes underlain by fractured shale caterial which allows underground water and radicactive waste to fica down hill thrcugh the fractures until it seeps to the surf ace within 250 feet of a perennial stream.
$l l

Ms. C e!- Mayes,
Conversely, the ;onnercial waste burial sites at Beatty and Hanford, where n: -i; ration of radicnuclides has been observed, are flat desert areas with very low precipita icn, a water table approximately 300 feet belts ground level ar.d a distance of 8 to 10 miles to the nearest perer.r.f al stream.
In addi:icn to these site characteristics, which prevent the migration of radicactive material from the desert waste burial sites, another significant difference between the proposed waste disposal technique and the noe discon'inued Oak Ridge methods is that the Dresden waste will be disposed of as a solid. At Oak Ridge over 35 million gallons of liquid radioactive waste was pumped into the disposal trenches. We estimate that approximately 7 million gallons of liquid waste was disposed of in Trench No. 7, which was identified as a source of chelated radionuclides Because cf the differences we have concluded that the Dresden wastes should be cis;csed of in dry burial site.
With respect to your reques: for information relative to a public hearing on this ratter, the Illinois Safe Energy Alliance (ISAE) by petition dated September 20, 1979, requested that the Nuclear Regulatory Commission hold a publi: hearing on this issue. This petition is under review in accordance with t'.e ; revisions of 10 CFR 2.205 of the Commission's regulations.
I enci se for your informaticn a copy of our letter accepting that petition.
We wili ;rovide you with a copy of our response to the ISEA petition when it is a.tilable.
l In sur.ary, the Dresden decantamination has been carefully planned to im:rr.e he safety of the react:r and reduce the exposure of plant pers:r.el cc radia' ion.
The waste produced by the process is similar in y:e 1..d quantity to tne was e routinely produced at Dresden and its prc:essinc, transportation, and disposal will not cause any new hazards not re.icusly evaluated and deemed acceptable.
Sincerely,
--C 21.
