Dear Mr. Olson:

Your recent letter to the Department of Energy's (DOE) Richlan? Operations manager, John Wagoner, of October.30, 1992, disapproving the DOE's requested change in Tri-Party Agreement milestones regarding the initiation of the. disposal of high-level radioactive waste in grout vaults at Hanford, raised substantial t concern with the Yakima Indian Nation. Specifically, our. concern is that the Department of-Ecology is urging the Department of Energy to proceed with grout disposal-when perforsance assessments indicate unacceptable long-term environmental / health hazards from the grout and when there is not a license from the Nuclear Regulatory Commission for such action. In light of this concern we sought a meeting with' Department.of Ecology representatives to gain. understanding of the steps you expect to take.in the near, future to. resolve this issue.- ~ On Friday, December-12,.1992, we met with Roger: Stanley and others. representing the Department'of Ecology-in our Wapato office.,. regarding this and-other matters associated with Hanford.-As a result-of this meeting,.it was_ agreed that the Department of-Ecology would solicit meaningful public: input in upcoming. decisions concerning the Hanford Tank Waste Remediation-System. (TWRS) design work;and grout disposal. It.was' discussed that immediate public participation'would be-- encouraged;..to. allow effective consideration of-public input, as well as thint of other.stakeholders such as ~ the Yakima-' Indian: Nation, befo a decision is-made on the issue, now' scheduled for -March.31,-19 2 by the DOE.- We note:that public involvement in this critical action: relative, to Hanford's' future is consistent with the conclusion of the-Nuclear Waste Council, which alsofindicated in'its last meeting a. desire to focus on the TWRS/ grout issue. Public review will alsol allow the criteria proposed by the.Hanford Future Site.Uses. 1 Working Group specifying unrestricted use of the Hanford~ central Plateau-100 years past closure.of the waste' management facilities 7

i to be factored into'the TWRS design. We consider the disposal of dangerous and radioactive wastes (for example, nitrates and organics as well as long-lived radioactive wastes) in the proposed. grout vaults to be inconsistent with this use criteria. We recommend that immediate action.is warranted to discuss public involvement with the Department of Energy. We need to obtain their support and participation with respect to public input, together with a commitment to receive and effectively resolve these issues. We stand ready to assist in this endeavor and look forward to the open discussion and resolution of the-issues.- Also, as a result of our meeting, it is our understanding that there is no action that could be taken by DOE in the next six months to in fact initiate grout disposal of double shell slurry waste as grout. Please inform us if this conclusion is incorrect. 3 Sincerely, Russell Jim, Manager r Environmental Restoration / Waste Management % '..i: 3' -m Yakima Indian Nation- ~ V--e !7 ~ P.O.

CHANGES IN HANFORD'S GROUT PROGRAM Bob Cook called me yesterday about potential changes in.Hanford's Grout. program for: incidental wastes. I forwarded the_ call onto you. The purpose of-this note-is.to summarize the information that Bob provided to me in case he did not connect'with you. According-to Bob, DOE has substantially changed its plansifor disposing the? ~ double and single.shell--tank wastes at the Hanford site. He. told me the preferred action is to abandon grout as a. disposal; medium in. favor of a. glass frit waste form for' incidental waste. ~ According to Bob, DOE'now plans to vitrify all of.the waste using;a high sodium glass'(25 to 30% Na. by weight). The high-activity waste will: be poured into 2360~ 11-cubic meter casks for ' 1 disposal at the repository.- The lower activity waste willf be produced as-a: glass frit,, mixed with liquidisulfur, and poured intoithe near_ surface; vaults. Prior to forming the waste, DOE will conduct additional' sludge washing: and ion exchange using zeolites. According toDBob, DOE projects that the new waste form will perform 10,000.-times better than.the_ grout and 'will= reduce' the number of vaults from 260 to 43. Bob said that'D0E also is considering a " Cook" option.of vitrifying all of the-j tank waste and' disposing of itLin the. repository... This option would' produce l 12,30011-cubic meter casks at a cost of. $11B. ' Bob also;believese that. DOE is ~ r trying to undermine this' option.by. claiming that;it would require construction of a secondl repository. According to Bob, this' reasoning _is; fallacious. because-DOE already knows it will need 'a second repository because. Yucca Mtn. is not large enough to accommodate all of the spent fuel and HLW projected by 2010. Bob said that these revisions are coming out of the rebaselining program that-DOE mentioned last July. _ DOE has used 6 different: stakeholder and peer review-groups to conduct multi-attribute analyses of the Hanford Tank Waste program.. Bob participated onione of _the _ groups. Bob also. commented.that DOE will: have to reissue its EIS for the tank waste program because it is:now more than'five. -years old. I! thanked' Bob:for the information~and forwarded h'im to.you, GivenTthat'the Commission.is1 presently finalizing (has-finalized).the SRM on the Hanford; petition, I suggest that~ycu contact DOE.to verify the1information received; from Bob CookLand inform the' Commission'.of updated information.-'NRCishould' (consider-revising the letter to DOE that was attached;to the' Commission; paper 'on the Hanford-petition to. reflect the new information.- J Mik'e ~ u CC: MVF,DJF2,jha,phl,ewb,cjg1L a -q. l 4; .=.

HANFORD MEETING

SUMMARY

COMMENTS -Reply Several changes to the letter to DOE on the Hanford Tank Meeting summt.ry. I would refrain from identifying specific NRC individuals; doing so implies that the NRC staff may have different views. Revise the comments as follows: 1. On comment #3, suggest revising as follows - "In response to an NRC question, Westinghouse Hanford staff stated that not all of the Hanford double shell tank waste had been treated or processed to remove key radionuclides." 2. On comment #4, suggest revising as follows - "In contrast to the estimate presented in the summary meeting notes, NRC staff recalled from the meeting that the estimate of short-lived radionuclide activity in the Hanford tank wastes was considerably less. The summary meeting notes state that the total-activity of short-lived radionuclides is less than 20 mci, but the NRC staff does not recall that such an estimate was provided in the meeting. Please verify the est! mate." 3. " Michael" is spelled Michael rather than Micheal. Please correct in the comments that follow comment #4. Thanks. Please contact Chad or myself if you have questions.
