SUBJECT: TRIP REPORT:PEER REVIEW.

NEVADA NUCLEAR WASTE STORAGE INVESTIGATIONSLAS VEGAS, AUGUST24-28, 1981.

0rmanization of MeetingThis meeting, the e ghth n a.sertes, covered a bryoadier spectrum of NWSIpnoject activities than previous ,per reviews The reviewers (dentif ledin figures 1. 2, 3) were divided amongthr.eegeneralsubjects: geology/hydrology, geotechnical/geoengineerng studies. and environmental-studies.From Monday morning. August 24,..through.tariyjTuesday -ilternoon, presenta ionswere made by the investigators to, the collective peer review group. Then,through early Thursday afternoon, the three reyew groups separately heardand discussed presentations on selected topis. Finally, the iellectivelreview group met in executive session through FrIday.,

About 130 observers were on hand., .

On Tuesday I provided to the collective rooup -ashort overview 'onthepresent status of 10 CFR 60. ,

Developments since the.Februiary NRC visitThe most striking impression to.me s thereorientation of the work alongtines that correspond to the observat1ons made in the NRC trip reportcovering the February trip to TS. *Espeocjally.tnotbWi s the attentionnow being given to 10 CFR 60.. which was described as,"the glue that holdsthe pieces together." The requirements of' the site characterization reportand the approach for the NRC review yere accurately escribed (figures4, 5 and 6). The schedule for SCR preparation and the NRC review (threemonths) was presented (figure) aind discussed. The U.S. eologicalSurvey showed a schedule of 19 geologic, hydrologic and geobWysical studiesfor which the SCR is the "drivtng force" In planntng. The SCR was describedas a "very good vehicle to inform-the public" aout project activities.

Other developments, too, are cnsonant with NRC' s trip observations:-

- The Bullfrog tuff is beingaassessed as-to ts strength and theanticipated stresses on underground openings at repository depthi Other. . _J2;>4ocle;1digan aboxe thr t r t ssdlt than lQp ee dep

- During September, the parameters-,of seismic exploration will bestudied on Yucca Mountain to detefiminewhether a r nefjed seismic approachwill work.

- There is improved integration of project elements..

- An interface with the national ,program is .pjnnedon performanceassessment. .

Pro ect ScheduleATiRb oitionof proJect plnning as taken place ince introduction ofthe test and evaluation facility (TEF).concept.- The TEF s intended to

. demonstrate (and win public confidence in) methods of receiving, transporting,retrieving, and shielding two to three hundred.HIW waste packages. It willbe constructed at one of three places: NTS, BWIP, or salt.

The present schedule is: ,1982 October. 3D performance assessment of tuffhorizons.

December. Select horizon and locate explqratory shaft (ES).

1983 March. Start site preparation fortheES. See figures 8 and 9 forcost estimates.and aetivities schedule ,,

June. Submit the SCR to NRC.,September. Start to sink ES. , .. ,

1984 June. Complete repository..coqeptual design report.

1985 September. "Confirm site" forW - ,

1986 December. Start at-depth)test fiac-1ty for,detailed. .s1te-_> characterization. Start TEF, ifKS is selected, among three

sites, for the TEF.,

The schedule for national program a4ctylytes 1s shown.,1ftgure 10. TheNNYSI program through FY 86 is sipwn 1r,,figure,11 ,

CommentsThere is a new note, n the NNWSi prject, qf heightened attention to licensingneeds and programmatic milestones.,, A number of geosc1qnce and geotechnicalquestions are, naturally, outstanding., These are being addressed and there isa sense of improved coordination amorqg .thq tasks.

However, two problems are presented to us in theplanning for the site '
