SUMMARY

-PERIOD 13 In the Division of Waste Management (DWM) Job Code (JC), the Center for Nuclear Waste Regulatory Analyses (CNWRA) continued work on numerous analyses and revisions to several issue resolution status reports. Staff delivered Slip Tendency, Dilation Tendency, and Anisotropic Permeability at Yucca Mountain, Nevada-Journal Ar ticle, which was also submitted for publication in Geology Today; Crossing Conjugate Normal Faults-Journal Article, an invited paper for the American Association of Petroleum Geologists book, Recognition and Characterization of Reservoir Scale Structures; and Auxiliary Analysis on Rock Falls-Journal Paper. Further, staff conveyed the Geographic Information System Archive--CNWRA Report and another report, Thermal-Mechanical Drift Stability Analysis at Repository Scale. He staff provided the CNWRA Input to Commission Paper on Draft Rulemaking through comments on the draft rule. Moreover, at the DISTEC '98 conference in Hamburg, Germany, staff presented a general overview paper and poster on the Nuclear Regulatory Commission (NRC) Total-system Performance Assessment approach that were jointly prepared by the NRC and CNWRA staffs.

He DWM JC year-to-date (YTD) cost variance was 9.7 percent. Spending rose from last period. Although the cumulative variance increased in dollars since the previous month, this variance decreased on a percentage basis as work accelerated in certain areas.

In the Tank Waste Remediation System JC, the report titled Assessment of the U.S. Department of Energy (DOE) Regulatory Unit Initial Safety Analysis Report of the British Nuclear Fuels Limited, Inc. Initial Safety Analysis Package Open items Part-I was delivered. The YTD cost variance was 4.8 percent. Spending rose slightly and the cumulative variance, both in absolute and relative terms, increased. Some milestones have been rescheduled into FY99 to meet budgetary restraints.

In the nree Mile Island Unit 2 (TMI-2) Independent Spent Fuel Storage Installation (ISFSI) JC, the  !

CNWRA technical staff continued preparation of the draft safety evaluation report, including evaluation of  !

the DOE response to the NRC second round request for additional information (RAI). The YTD cost variance for the TMI 2 ISFSI was 14.0 percent-rellecting staff participation in the site visit to the Idaho National '

Engineering and Environmental Laboratory (INEEL).

In the Dry Transfer System JC, the staff also participated in the site visit to INEEL. The YTD cost variance was 28.9 percent, down from last period on a percentage basis, because ofincreased costs associated with staff travel to the site.

In the Centralized Interim Storage Facility (CISF) JC, staff continued to evaluate the DOE response to the N RC RAI and prepare the draft assessment report. The YTD cost variance for the CISF was 2.5 percent. This variance increased slightly, reflecting decreased spending over the previous period.

In the Private Fuel Storage Facility JC, the staff submitted the Second Round Request for Additional Information-Final Letter Report. De YTD cost variance was 19.3 percent, notwithstanding increased spending in this JC.

In the Savannah River Site Aluminum-Based Spent Fuel (SRSASF) JC, the staff worked on various milestones. De YTD cost variance increased to 39.1 percent. Spending rose over the previous period.

It should be noted that the current spending estimates in all JCs are based on the assumption that staffing is at authorized levels. Current staffing remains below authorized levels and recruitment continues.

ESTIMATED BUDGET: $87,611,477 PERIOD OF PERFORMANCE: 09/27/97-09/27/02 PERIOD OF THIS REPORT: 08/29/98-09/25/98 1 TECHNICAL 1.1 CNWRA Operations (COPS)

In addition to a wide range of day-to-day activities, accomplishments in the management l and planning area included (1) preparing for the 1998 CNWRA Annual Program Review; l (ii) responding to the revised Interim Guidance for the Development of Fiscal Year 1999 l CNWRA OPS for the repository program (DWM, TWRS, and SFPO) by preparing the necessary documents; (iii) providing financial information for the balance of this FY and for carryover monies for the next FY; (iv) further addressing COI-related issues among the NRC, SwRI, and CNWRA management staffs; and (v) participating in weekly HLW Management Board meetings.

Status of CNWRA staffing is indicated in table 1, consistent with the revised staffing plan submitted as part of the revision to the CNWRA Management Plan. During period 13, recruitment efforts and interviews continued for the approved open positions. One limited-term employee accepted an offer and will begin employment in period 3 next FY.

Computer system support activities encompassed (i) employing a UNIX administrator for SUN Microsystems and Silicon Graphics systems; (ii) preparing to receive the hardware and software associated with the GIS and IMS computing facilities; (iii) implementing a strategy for standardizing desktop computer systems; (iv) pursuing a replacement for the 1

l

a L-CDOCS software; (v) participating, as requested, in the monthly NRC/CNWR A Computer Coordination meeting; and (vi) maintaining LAN operations. -

QA activides focused on (i) finishing the revision of QAP-001, Scientific Notebook Control, and distribudng it to CNWRA staff members in response to one of the QA audit CARS; (ii) making draft changes to another QAP dealing with procurement control and soliciting comments from CNWRA staff members expected to implement the procedure; (iii) conducting surveillances, issuing nonconformance reports as required, and working with cognizant staff in response to these reports; (iv) leading the configuradon control effort of the CNWRA scientific and engineering software determined ready for release; (v) controlling issued documents and maintaining QA records; (vi) preventing organizational COls by reviewing SwRI RFPs; (vil) performing QA verification checks on each CNWRA deliverable; Jnd (viii) evaluating potential changes to the CNWRA Quality Assurance Manual, which may be required as flow-down QAPs are revised.

In the next period, the CNWRA staff expects to (i) prepare for the 1998 CNWRA Annual Program Review; (ii) complete development of the FY99 CNWRA OPS; (iii) pursue hiring for open core staff positions; (iv) prepare for installation of computer hardware and software for GIS and IMS computing facilities, as well as continue the search for a replacement for the CDOCS software; and (v) provide CNWRA LAN operation and maintenance support. (

In addition, the staff will (i) complete work on the second CAR and review the second revised QAP identified as deficient in the FY98 CNWRA QA Audit, (ii) proceed with scheduled QA surveillances, (iii) perform QA indoctrinations for new CNWRA staff and consultants, (iv) input internal documentation and record copies of delivered documents into QA records, (v) review SwRI RFPs for potential COI, (vi) perform QA verification  ;

checks on each CNWRA outgoing deliverable, and (vii) consider a change to the CNWR A CQAM relating to comments made during the QA audit.

1.2 Igneous Activity (IA)

Staff documented a detailed examination of the process of rock-fragment entrainment and conduit development in ajournal article entitled Xenolith Formation and the Development of Basaltic Volcanic Conduits During the 1975 Tolbachik Eruptions, Kamchatka, with Implications for Volcanic Hazards Assessments at Yucca Mountain, Nevada (IM 1402-461-860). This journal article, currently under internal review, examines how the volcanic conduit progressively enlarges during an eruption by eroding shallow (< 2 km deep) wall-rocks by several mechanisms. Using data from the 1975 Tolbachikeruptions in Kamchatka, Russia, conduits enlarged from initial diameters around 5 m to around 15 m by the end of cone-forming activity. Late-stage interactions between > 500-m-deep groundwater, heated wall-rock, and basaltic magma resulted in explosive expansion of water. These explosions resulted in significant wall-rock disruption and expanded conduits to around 48 m in diameter. The youngest basaltic volcanoes in the YMR have cone deposits characterized by elevated rock-fragment abundances and distinctive rock-fragment blocks. These features are characteristic of conduit widening events at the 1975 Tolbachik volcanoes.

Extrapolation of the 1975 Tolbachik data suggests conduits for some YMR basaltic volcanoes may have widened on the order of 50 m in response to late-stage interactions between subsurf ace groundwater and the heated conduit. Volcanic disruption models in TPA Version 3.2 consider that conduits may range from 10 to 50 m in diameter at 2 ,

repository depths. The contents of the previously mentioned journal article provide the technical basis in support of this range. l l

Staff continued to review chapter 10 of the draft DOE TSPA-VA Technical Basis document l

in preparation for the October 5-6,1998, DOE /NRC Appendix 7 hiecting on Disruptive l Events. Acceptance criteria for the consequences ofigneous activity developed in revision 1 I of the I A-KTI IRS R specify staff technical bases for issue resolution. These criteria provide l the framework for review of the draft DOE TSPA-VA Technical Basis document. Staff have several questions regarding the data and models used by the DOE to conclude that the l

probability of future igneous activity at the proposed repository site la iow enough to permit  !

dismissal of this scenario class and that the dose consequences of volcanic disruption are 6

< 10-' rem /yr over a 10 postclosure period considered by DOE. These questions focus on l

technical bases used to restrict future volcanism to the Crater Flat area, WP and waste-form l

resilience during igneous events, cruption character for basaltic volcanoes, and dose modeling.

In the next period, IA staff will submit Xenolith Formation and the Development of Basaltic Volcanic Conduits During the 1975 Tolbachik Eruptions, Kamchatka, with Implications for Volcanic Hazards Assessments at Yucca hiountain, Nevada-Journal l Article (IM 1402-461-860). Staff also will participatein an DOE /NRC Appendix 7 Meeting on Disruptive Events. Preparation for the CNWRA Annual Program Review will begin.

Work will continue on repository-magma interactions, including modeling of magma + gas velocities in repository drifts and temperature gradients in the drifts during igneous activity.

1.3 Structural Deformation and Seismicity (SDS)

Staff submitted three milestones. The first milestone is a journal manuscript entitled Slip  ;

Tendency, Dilation Tendency, and Anisotropic Permeability at Yucca Mountain, Nevada-Journal Article (IM 1402-471-862). The manuscript uses 3DSTRESS and a reinterpretation of the C-Well complex pumping data to show that fracture permeability at YM is anisotropic. The manuscript will be submitted to the Geological Society of America monthly publication Geology Today. The second milestone is an update of the GIS Archive-CNWRA Report (IM 1402-471-850). The GIS archive update has been submitted l on a CDROM and contains CNWRA developed data, as well as data acquired from other sources. Coverages include global, regional, and local areas. Gravity and magnetic surveys, landsat images and aerial photographs, geochemical analyses, and benchmarks and geoposition references are some of the included data. The third milestone is a manuscript entitled Crossing Conjugate Normal Faults-Journal Article (IM 1402-471-950). The manuscript is an invited paper for the American Association of Petroleum Geologists book, Recognition and Characterization of Reservoir Scale Structures, and shows how deformation mechanisms related to the development of crossing conjugate normal faults lead to permeability anisotropy and channelization of groundwater flow in faults, including the faulted rocks beneath YM. The manuscript was originally planned as a FY99 milestone, but completed and submitted ahead of schedule.

Staff also completed a review of the DOE Geologic Framework Model 3.0. The review was scheduled as an IM--CNWRA Report (IM 1402-471-865), however, because of a change in scope, the review will now be submitted as an Al that will be incorporated into the SDS IRSR. Staff continue work on an EARTHVISION model of the structural framework of the Amargosa trough, identified as 3D Structural Model of Amargosa for input to 3

.A b-

+

4 USFIC-CNWRA Report (IM 1402-471 860). The model will be used as input to saturated flow models by the USFIC KTI. Staff also continued work on Structural Evolution of Crater Flat Nevada-Journal Article (IM 1402-471-832).

Staff participated in GPS field work in the Volcanic Tablelands of eastern California. The GPS work will be used to test alternative models of crustal strain accumulation and release recently advocated by Wernicke et al. In a 1998 Science article. In addition, staff completed the SDS portion of the FY99 CNWRA OPS.

In the next period, staff will continue review of the DOE probabilistic seismic and fault displacement hazard analyses report. Staff will pardcipate in the. DOFJNRC Appendix 7 Meeting in Las Vegas, Nevada, on Scenarios and Disruptive Events. Staff will also participate in two field trips, one to review the surficial record of faulting in the YM led by the Friends of the Pleistocene and one to continue evaluation of crustal strains in the Volcanic Tablelands of eastern California.

1.4 Evolution of the Near-Field Environment (ENFE)

Preparation of the ENFE portion of the FY99 CNWRA OPS continued, including the scoping of technical activities through discussions with the NRC PEM.

Solubility computadons continued to examine a suite of possible near-field solution chemistries and solubility-controlling phases.

I Staff continued debugging, testing, and documenting the MULTIFLO code Version 1.2p.

Software validation tests continued on the new DCM capabilities in the METRA flow module. Similar tests were initiated for the GEM reactive-transpon module. These tests identified a number of coding errors, which were corrected. Testing also revealed potential l run time and numerical diffusion problems in the current numerical implementation; these ,

are being studied in more detail. Work continues on the semi-implicit operator splitting algorithrn. A MULTIFLO simulation for a ID carbonate system and WP heat source was successfully benchmarked and verilled using the code EQ3/6 Version 7.2b. The pH dependent kinede dissolution and precipitation of amorphous silica is being benchmarked using a fixed volume porous medium model under no-ilow, isothermal conditions.

Staff participated in a DOE /NRC Appendix 7 Meeting on Cementitious Materials, September 2- 3,1998, in Las Vegas, Nevada, and participated in an associated tour of the YM site. Highlights of the Appendix 7 meeting were presented at a YM team meeting. Staff also panicipated in the DOE /NRC License Application Technical Exchange by videoconference on September 16,1998.

Staff continued review of the LLNL Near-Field and Altered-Zone Models Report and initiated review of the draft DOE TSPA-VA Technical Basis document, particularly Chapter 4 Near-Field Geochemical Environment.

l l In the next period, the CNWRA staff will condnue preparation of the FY99 CNWRA OPS l and review of the draft DOE TSPA-VA Technical Basis document. A meeting is planned to establish the technical basis for revision of the SRD for the MULTIFLO code.

Debugging and benchmarking of this code will continue. Near-field radioelement solubility .

L modeling and aqueous actinide chemistry studies will advance. Preparations are ongoing

O d for participation in a October 29,1998, meeting at the NRC on coupled THC effects on UZ flow. A paper on PA sensitivity studies related to the dependence of the source term on near-fleid environmental conditions will be completed and submitted for internal review.

1.5 Container Life and Source Term (CLST)

Technical and programmade comments of the NRC staff on the Container Life and Source Term IRSR, Rev.1, were addressed. Staff completed the CLST portion of the FY99 CNWRA OPS and comments were resolved.

Electrochemical corrosion testing, performed to confirm the applicability of repassivation and corrosion potentials as predictive parameters for the long-term, localized corrosion of Alloy 825 in chloride-containing solutions at 95 *C, was temporarily interrupted after a total time of 1,479 days due to an extended power failure affecting the laboratory facilities.

The specimens were removed from the test cells, examined for signs oflocalized corrosion, and weighed. Several small shallow regions of crevice corrosion were observed on the specimens tested at the corrosion potential under air saturated conditions for a total of 1,074 days. During 6 months of continuous exposure to the 1,000 ppm chloride solutions, the corrosion potential reached levels as high as 300 mVscs. No localized corrosion was observed on specimens maintained below the repassivation potential. After inspection, all long-term tests were restarted.

The load frame that will be used to precrack the Alloy C-22 and type 316L SS double cantilever beam specimens for stress corrosion cracking testing has been calibrated according to ASTM E4. One specimen of each material is being used to generate compliance curves as a function of crack length. Specimens of 316L SS will be tested to validate the testing procedure by combining them with existing data. When complete, the set of compliance curves will be used to determine the crack opening displacement and necessary loading wedge thickness for the initial stress intensities to be used in die tests.

Fatigue precracking and wedge loading of specimens exposed to a acidified chloride soE o will begin after the compliance curves are completed. For Alloy C-22, testing will be aicted using initial stress intensities of 30 and 40 MPa mu2. For type 316L SS, speumens : vill be tested with initial stress intensities of 20 and 40 MPa m u2 ,

Localized corrosion testing of Alloy C-22 in solutions with chloride concentrations of 0.5, 1.0, and 4.0 M at temperatures ranging from 95 to 175 *C continues. Cyclic potentiodynamic polarization curves are being determined using creviced specimens of Alloy C-22. An internal Ag/AgC1/ kcl (0.1 M) reference electrode, calibrated at room temperature against a saturated calomel electrode, is used in these measurements.

Components to assemble an additional internal Ag/AgCl/Cl reference electrode were obtained. Prior to its use, the new internal reference electrode will be calibrated.

The interdependence of solution chemistry, temperature, and potential on localized corrosion of A 516 carbon steel is being investigated in simulated repository environments containing bicarbonate and chloride anions. Potentiostatic crevice corrosion testing of carbon steel progresses, primarily focusing on the effect of pH (from 8.2 to 11.0),

temperature (20,65, and 95 *C), and chloride concentration (1.2 to 50 mM). Further work aimed at the lower pH corrosion regime has begun with particular emphasis on whether localized corrosion initiation occurs at pH values less than 9.5.

5

i b 6 In the next period, long-term corrosion tests of Alloy 825 will continue, as will localized corrosion testing of A 516 carbon steel and Alloys C-22 and 625. Stress corrosion cracking testing of Alloy C-22 will also begin. Technical assistance to the NRC for preparation of the CLST IRSR Rev.1 is expected to be completed.

1.6 Thermal Effects on Flow (TEF) he staff continued testing of the DCM capability in the MULTIFLO code. Drift-scale 2D models were compared to the DOE results reported in the DOE Near Field / Altered Zone Report. The formation of heat pipes in the model results was evaluated. The thermal source term was modified to reflect the current assessments of projected repository thermal load.

The second phase of the laboratory-scale boiling isotherm depression heater experiment continued during the reporting period. Integration of this heater test with the CLST and ENFE KTIs was explored. A parallel experiment has been designed to evaluate the evolution of the infiltration water chemistry as it reacts with the pretest concrete. He CLST KTI team initiated efforts to design a candidate material assessment apparatus that can be incorporated into the laboratory-scale heater test.

Interpretation of results from the first laboratory-scale heater test continued. These results were analyzed and modeled with MULTIFLO-DCM. A paper describing the experimental and modeling results was submitted to the Second International Symposium on Two-Phase Flow Modeling and Experimentation.

Numerical modeling of the DOE DST and LBT was temporarily suspended pending availability of staff currently assigned to another KTI task. These analyses will resume in FY99.

An abstract on the Mechanistic Refluxing Model was submitted to the Witherspoon Conference on Flow Through Fractured Media.

Sensitivity analyses using the REFLUX 3 module of the TPA Version 3.2 code continued and will be completed when the final reference base case is assembled.

In the next period, TEF KTI staff plans to (i) initiate the next phase of the boiling isotherm penetration laboratory-scale experiment, (ii) continue analysis of the results from the first phase of the laboratory-scale heater test, (iii) continue testing of the MULTIFLO-DCM numerical code, (iv) evaluate the conceptual model of refluxing, (v) attend the DOE quarterly thermal test workshop at LLNL, and (vi) attend the vadose zone workshop at Colorado School of Mines.

1.7 Repository Design and Thermal Mechanical Effects (RDTME)

During this period, the staff continued the analyses, using the UDEC code, to predict rockfall under seismic load in the repository thermal environment. 'This simulation work

( is expected to provide a technical basis for determining the magnitude of the dynamic l

impact load on the WPs resulting from rockfall. Also, the results will be used as input to the SEISMO module in the TPA code for dismptive scenario assessment, ne progress to date regarding the rockfall study was submitted as Auxiliary Analysis on Rock Falls-Journal Paper or Presentation (IM 1402-671-830).

6

o O G A report documenting the preliminary results regarding the study of the rock mass behavior under heated conditions at the repository scale was conveyed as Thi Drift Stability Analysis at Repository Scale (thi 1402-671 -845). The report emphasized the effect of variability and long term degradation of rock mass material properties and strengths on the stability of repository drifts.

The investigation of drift-scale rock mass behavior and its effect on concrete lining stability using UDEC progressed during this reporting period. Staff continued the literature review on concrete performance at high temperature. The review will provide valuable information to assess the DOE design of the concrete liner for use at high temperature.

Three abstracts on Thi and seismic behavior of repository drifts were prepared and submitted for presentation at the 37* U.S. Rock hiechanics Symposium to be held in Vail, Colorado, June 6-9,1999.

In the next period, RDThf E KTI staff plans to (i) review the literature collected on concrete performance at high temperature, (ii) investigate rock mass behavior under heated conditions on both repository and drift scales with an emphasis on long-term degradation of rock mass material properties and strengths, (iii) conduct rockfall simulations, (iv) use the AB AQUS code to model WPs, (v) attend the DOE quarterly thermal test workshop at LLNL, and (vi) conduct reactive activities including review of design documents.

1.8 Total System Performance Assessment and Integration (TSPAI)

Work on User's Guide for TPA Version 3.2-Letter Report (IM 1402-762-810) continued in preparation for submittal on September 30,1998. Technical and programmatic reviews of the document were jointly conducted by the NRC/CNWRA staffs. Finalizing the basis for choosing parameter values for the NRC data set was completed and appendix A updated.

The nomination letter and proposed scope and schedule for conducting a formal external review of the TPA. Version 3.2 code were presented to the HLW hianagement Board; these were modified in response to board and staff comments. Consideration of NEA conducting the external review (to reduce costs and avoid any semblance of COI) is awaiting an NRC decision in light of a concern raised regarding the tight review schedule. In the meantime, work continued to update the list of nominators as the first of the nomination packages was dissenunated.

Considerable progress was made on Input to TPA Version 3.1 Sensitivity Studies Report-Letter Report (Ihi 1402-761-810). Technical review of Volume I: Conceptual hiodels and Data was completed and editorial review initiated. Volume II: Results and Conclusions has undergone revision in response to editorial and programmatic reviews conducted by the NRC and CNWRA staffs. A decision was made to publish the two-volume report as NUREG-1668 instead of NUREG/CR-5549, since this report represents ajoint efforts by the NRC and CNWRA PA staffs. To accommodate timely delivery of the

user's guide for TPA Version 3.2, October 21,1998 was approved by the NRC as the new submission date for the two volumes.

The staff presented a general overview paper and poster on the NRC TPA approach, jointly prepared by the NRC and CNWRA staffs, at the DISTEC '98 conference held l

7

b b September 9-11,1998, in Hamburg, Germany. Moreover, staff completed TSPAI input to the FY99 CNWRA OPS.

Significant progress was made on (i) the PC version of the TPA Version 3.2 code, (ii) the Java-based post processor for the TPA Version 3.2 code, and (iii) the PVM implementation of the TPA Version 3.2 code. The PC version of the TPA Version 3.2 code has been developed to run under the Windows NT operating system. Continuing problems in executing the TPA code appear to be caused by a bug in the Lahey Fortran compiler. The Lahey support group was contacted to address the problems. Testing of the Java-based post processor continued and the on-screen help option is currently under development. The PVM version of the TPA Version 3.2 code is currently undergoing testing on the CNWRA SUN network and the user's manual is under preparation.

In the next period, the PA staff will focus on (i) completing the first volume of Input to TPA Version 3.1 Sensitivity Studies Report-Letter Report (IM 1402-761-810);

(ii) finalizing the second volume of the Input to TPA Version 3.1 Sensitivity Studies Report-Letter Report (IM 1402-761-810), which reflects actual results of the sensitivity study; (iii) attending an Appendix 7 meeting on scenarios in Las Vegas, Nevada; (iv) assisting the NRC with revisions to the Total System Performance Assessment IRSR; (v) finalizing the approach for the external review of the TPA Version 3.2 code; and (vi) completing the PC and PVM versions of TPA Version 3.2 code and the Java-based post processor for the TPA Version 3.2 code. In addition, recruitment is ongoing for the PA modeler and risk assessment positions.

1.9 Activities Related to Developmen t of the NRC High Level Waste Regulations (ARDR)

The staff submitted their contribution to the CNWRA Input to Commission Paper on Draft Conforming Rulemaking (IM 1402-771-820) through comments on the draft rule and provided text as requested by the NRC. In addition, they completed their input to the FY99 CNWRA OPS.

The staff progressed on evaluating the effects of well characteristics and plume dimensions on dose estimates, which are needed to support development of attributes of the critical group to be used in 10 CFR Part 63. The purpose of this task is to determine if using more complex models of site hydrogeology affect estimates of radionuclide concentrations at pumping wells for both residential and agricultural receptor locations. The modeling approach that has been adopted incorporates spatially variable material properties, complex initial and boundary conditions, and multiple pumping wells with variable pumping rates.

This period, the IS ATIS program was used to develop a geostatistical model of conductivity in the welded tuff aquifer using pooled data from both large- and small-scale tests. 'Ihe geostatistical model was used to generate randomly correlated conductivity fields. An additional geostatistical model was also developed from the large-scale test data.

Efforts to incorporate soil survey map data for the region surrounding YM into the CNWRA GIS database continued. The information obtained from the Soil Conservation ,

Service provides spatial characterizations of soll taxonomies for the region. The spatial soil data will provide an additional coverage of GIS data that can be used with other regional GIS data to support definition of the critical group at YM. This period, the need to digitize the map information was obviated because the same information was found in digital format on the Natural Resources Conservation Service web site. All quadrangles for the area of 8

4 a southern Nye County were downloaded and processed into one large coverage for the area.

Attribute data were then reviewed to determine the utility of including additional information in the new coverage.

In response to issues brought forward at a recent DOE /NRC technical exchange, the investigation on issues pertaining to calculation of age-specific doses at Yht continued.

Age-specific DCFs were identified and preparations were made for initial calculations.

At the end of this period, staff began revising the previously issued report, Information and Analyses to Support Selection of Critical Groups and Reference Biospheres for Yucca Mountain Exposure Scenarios. The revised report is intended to be issued as a N UREG/CR and will be a key reference document for the rulemaking effort and TSPAI activities.

In the next period, staff will complete a geostatistical model based on small-scale test data.

The dilution study will focus or estimating additional structure in the welded tuff aquifer using other data sources. Assessment of age-specific DCFs will continue and the initial results made available to the NRC. If EPA publishes the draft standard, staff will assist tbc NRC with reviewing it and preparing comments. The revised report on Information and Analyses to Support Selection of Critical Groups and Reference Biospheres for Yucca Mountain Exposure Scenarios will be formatted for delivery.

1.10 Unsaturated and Saturated Flow Under Isothermal Conditions (USFIC)

Close interactions with the NRC staff continued during this period to support development of the USFIC IRSR, Revision 1.

The staff attended the inaugural meeting of the NAS expert panel on conceptual models of flow and transport in the fractured vadose zone. The panel will convene a workshop in March 1999 and produce a summary report along with papers from invited speakers by August 1999. The report will focus on the iterative process of developing a conceptual model for fractured media, isolating the important physical processes, and establishing the methodologies for parameterization and quantifying uncertainty.

USFIC staff attended a FRACMAN modeling workshop in Seattle, Washington, September 14- 18,1998. The FRACMAN software and the accompanying MAFIC module will be used to perform discrete fracture modeling of the C-Well hydraulic and trscer tests.

USFIC staff collaborated with SDS staff to write a manuscript entitled Slip Tendency, Dilation Tendency, and Anisotropic Permeability at Yucca Mountain, Nevada-Joumal Article (IM 1402-471-862). USFIC contributions to this manuscript included an analysis of regional anisotropy in the hydraulic transmissivity of the volcanic tuff aquifer, based on interpretations of the C-Well hydraulic tests, and an analysis of the effect of anisotropy on groundwater flow paths.

Chracterization of nonwelded vitric layers below the potential repository horizon continued. Geophysical data obtained from the DOE is being plotted against mineral logs and x-ray diffraction data to estimate aggregate thicknesses of vitric layers for use in PA.

Characterization of strata in the Calico Hills Unit and the Prow Pass Tuffis also being used to support alternative conceptual models for flow and transpori from the repository horizon to the water table.

c A Analysis of the potential hydrologic impact of the invasion of Bromus continued. Bromus is a non-native grass currently found at and around YM. The influence of this grass on infiltration is of interest because of its early season life cycle, shallow rooting patterns, and ability to replace native vegetation rather than coexist. Studies on Bromus invasion in other areas indicate the possibility ofincreased flux of water to the water table. Literature review on the impact of Bromus continues.

The results from 4401 D bare-soil simulations were collected, documented, and assessed.

Improved representations were derived for MAI as a function of climate, soil, and fracture properties. Implications for deep percoladon under climatic change were examined, including the direct meteorologic effects of climate change and the indirect effects of change in soil texture and thickness. The simulations suggest that changes in soil properties may in large part counteract direct climatic change effects, although soil genesis will likely significantly lag climatic change.

Efforts continued toward developing an improved conceptual model of seepage into drifts under isothermal condidons. Modeling of the liquid injection test above niche 3,650 confirmed the results of LLNL studies and highlighted the dependence of model results on assumed boundary conditions and domain geometry. An analysis was also conducted comparing two methods of representing drift space: drift elements with a constant zero matric potential condition versus drift elements that simply use alarge van Genuchten alpha parameter. Preliminary results showed that while drift representation makes some difference, it is a relatively small factor in the overall results. A comparison of domains using the arbitrarily located no-ilow boundaries in the LLNL model versus natural no-flow boundaries may illuminate the influence of domain geometry and boundary condidons on the TSPA-VA model of seepage into drifts. It is clear that a 3D domain will be necessary when incorporating heterogeneity and this will require greater simulation run times.

Development progressed on a preliminary 3D geological model of the area south of YM, in collaboration with the SDS KTI. A site-scale model for the YM area was extracted from the regional model for the NTS area. Refining the spatial resolution of the site-scale model with available data also progressed.

Interpretation of data from the CNWRA field studies at YM continued. Gravity survey data were used to develop a preliminary two-layer subsurface model for the Amargosa Farms area.

In the next period, USFIC activities will include (i) interpretation of data from the CNWRA field studies at YM, (11) progress on alternative conceptual models for flow and transport from the potential repository to the water table, (iii) progress on approaches for modeling future inflitration, (iv) continued development of conceptual models for seepage into drifts, (v) review of the LBNL site-scale UZ model of YM, (vi) site visit to YM, (vil) preparation of a 3D subregional site-scale flow and transport model, (viii) ongoing interaction with the NRC working group on structural controls on groundwater flow, and (ix) continued efforts toward interpreting data from C.Well hydraulic and tracer tests.

D 4 1.11 Radionuclide Transport (RT)

Work continued on two manuscripts for publication in the proceedings volume of the hiaterials Research Society Symposium on the Scientific Basis for Nuclear Waste hianagement XXII, Boston, hiassachusetts, November 30-December 3,1998. The iirst manuscript, entitled Radionuclide Sorption at Yucca hiountain, Nevada-Demonstration of an Alternative Approach for PA, uses mechanistic sorption models and site-specific hydrochemical data to constrain Ko PDFs for PA abstractions and provides a discussion of spatial distributions of calculated Ko in the vicinity of Yht. The total range in calculated Ko for Np and U sorption is as much as nine orders of magnitude, but the total range in the immediate vicinity downgradient from Yht is typically much less.

In the second manuscript, entitled Unsaturated Zone Waters From the Nopal I Natural Analog, Chihuahua, hiexico-Implications for Radionuclide Niobility at Yhi, chemical data on Nopal I UZ waters are used to model uranium speciation and solubility and reaction paths affected by uraninite dissolution. hiodeling shows that resulting aqueous urardum concentrations are highly sensitive to (i) adopted solubility products for phases such as soddyite and haiweeite, for which such data are uncertain over several orders of magnitude; (ii) redox conditions as constrained by oxygen fugacities in open versus closed systems; (iii) carbonate contents related to CO2 fugacity and calcite saturation state; and (iv) starting aqueous SiO2 contents. Dissolved U contents as high as 6 x 10-3 molal are calculated. The lhi numbers for these products will be established in the FY99 CNWRA OPS.

A draft of a manuscript was completed for submittal to a peer-reviewed journal. This j manuscript is based on an evaluation of data (published literature and unpublished CNWR A '

results) on ion exchange between aqueous solutions and the zeolite mineral clinoptilolite.

It also discusses a thermodynamic model for describing and predicting ion exchange '

equilibria. A literature review was concluded on geochemical parameters likely to control colloid stability during transport; the CNWRA staff are reviewing and evaluating the literature to determine which, if any, parameters can be used to develop abstractions of colloid transport suitable for PA. The effects of the pseudo-colloid formation on RT parameters are being investigated using mechanistic sorption models, site-specific hydrochemistry, and observed natural colloid concentrations in the vicinity of Yht. This paper is proposed as a new deliverable in table 2 of this Ph1PR, Experimental and hiodeling Study of Ion Exchange Between Aqueous Solutions and the Zeolite hiineral Clinoptitolite (thi 1402-871-940).

Well logs for water wells drilled in the vicinity of Yht were screened and located on topographic maps of the Yhi vicinity. Several hundred wells drilled over a 50-yr period were examined. About 65 wells drilled during the 1980s and 1990s provided a representative coverage of the alluvial wells. Lithologic information in these logs was been entered into an electronic database that includes alluvium lithology, limited mineralogy information, depth to water, perforated intervals, and producing horizons. The well locations have been digitized to yield UThi coordinates and the DEh1 coverages for the region are being used to determine the elevation of each wellhead.

Liquid scintillation analysis was completed for a set of experiments to exandne uranium-

) 233 sorption on clinoptilolite. hiineral preparation continued for quartz-clinoptitolite mixed l mineral absorption experiments. One hundred eighty-five g of quartz has been prepared l with a surface area to mass ratio of 0.280 sq. m/g.

I1

D D The CNWRA staff continued to assist the NRC staff in finalizing the .RT IRSR. The CNWRA staff also continued to develop input for the FY99 CNWRA OPS.

In the next period, technical and programmatic reviews of the manuscript on ion exchange equilibria will be completed and submitted for publication in the Journal of Solution Chemistry. Well logs will continue to be used to constmet a database for alluvium mineralogy Peer-reviewed papers on the application of sorption modeling for PA calculations will be prepared. There will be continued laboratory analysis, including initiation of multiple-mineral experiments. RT staff will assist in the PA abstraction process. The staff will support completion of the FY99 CNWRA OPS.

SUMMARY

OF FINANCIAL STATUS Table 4 summarizes the CNWRA financial status in the context of authorized funds provided by the NRC. Total commitments of the CNWRA are $ 161,198. The appendix lists planned and actual costs to date, as well as variances between these, without allowance for fee, on both a per-period and a I cumulative basis. 'Ihese data do not include commitments. Pertinent financial information is l

provided for the DWM JC, including COPS and 10 KTIs, TWRS JC, TMI-2 ISFSI JC, DTS JC, CISF JC, PFSF JC, and SRSASF JC, The planned costs per period are based on the spending plans contained in the CNWRA OPS, Revision 10, Change 2, for the DWM JC; TWRS OPS, Revision 1, Change 1, for the TWRS JC; SFPO OPS, Revision 1, Change 5 for the TMI-2 ISFSI, DTS, CISF, and PFSF JCs; and SRSASF OPS, Revision 0, Change 2, for the SRSASF JC.

It should be noted the current spending estimates in all JCs are based on the assumption that staffing is at authorized levels. Staffing remains below authorized levels and accelerated recruitment is in progress. An updated staffing plan was delivered as part of Revision 6, Change 3, to the CNWRA Management Plan.

Period 13 FY98 CNWRA composite expenditures rose 1.1 percent from last period, and this aggregate of all JCs was underspent by $1,135,587 or 10.0 percent. Only the CISF JC evidenced

, lower spending levels, while the DWM, TWRS, TMI-2 ISFSI, DTS, PFSF, and SRSASF JCs I showed higher levels. In percentages, the DTS, PFSF, and SRSASF JCs registered a sharp rise in expenses in contrast with a significant decline in expenditures for the CISF JC, Specific explanations for these swings are provided in the individual sections of each JC.

The DWM JC was underspent by $942,404 or 9.7 percent. Overall expenditures increased l

2.6 percent from the previous period as costs rose in the SDS, ENFE, RDTME, TSPA, ARDR, and l RT KTis, but declined in COPS and the IA, CLST, TEF, and USFIC KTIs.

FY98 spending was about $8,740K before fee. This amount is consistent with the estimate made the previous period and the summary carryover analysis conveyed earlier this period.

Work and associated spending accelerated in the last six periods compared to the first seven periods of this fiscal year. Per period expenditures for the last six periods averaged $777,903, without fee, while those for the seven previous periods were $581,745-evidencing a 33.7 percent increase in i

14 l

1 o * .,

per-period spending. Moreover, the variance between estimated and actual aggregate spending narrowed to approximately 10 percent in the last three periods, markedly below the highs of 15-17 percent that occurred in the first few periods of this FY. A further comparison between these two intervals reveals a net increase of six core FTE and 15 qualified consultants and subcontractors from l period 1 through period 13. Spending on consultants and subcontractors rose by 33 percent in the most recent six periods relative to the initial seven periods.

Furthermore, the mean projected spending for periods 10--13 was $833,851 without fee. This per- l period expenditure approximates expected spending for the first three periods of FY99, based on l the most recent budget estimates.

The TWRS JC was underspent by $39,759 or 4.8 percent. Although spending increased over last period, the cumulative variance increased, primarily the result of reduced activity and rescheduled deliverables.

The TMI-2 ISFSI JC was underspent by $22,037 or 14.0 percent. Costs rose from the last period as a result of CNWRA staff participation at the INEEL site visit.

The DTS JC was underspent by $55,625 or 28.9 percent. Spending increased dramatically from the last period because of staff participation at the INEEL site visit.

The CISF JC was underspent by $5,633 or 2.5 percent. Expenses declined significantly from the previous period as work involving evaluation of the DOE response to the NRC First Round RAI for incorporation into a draft AR continued, no new work was assigned, and resources were directed to PFSF work.

De PFSF JC was underspent by $27,605 or 19.3 percent. Expenditures doubled over last period as work resumed on the review and evaluation of the PFS Limited Liability Company response to the NRC First Round RAI, along with the preparation of the Second Round RAI.

The SRS ASF JC was underspent by $42,526 or 39.1 percent. Spending increased over last period.

His increase may be attributed to preparation of a letter report and the SRSASF section in the operations plan.

The CNWRA expenditures on SwRI labor, consultants, and subcontractors as a proportion of composite spending on all JCs were 26.1 percent. The CNWRA ei; pense on consultants and subcontractors as a fraction of composite spending on all JCs was 19.0 parcent. Rese percentages increased from the previous period-reflecting the payment of outstanding vouchers. The CNWRA remains committed to enhance, where appropriate, participation of consultants and subcontractors in the cor. duct of the CNWRA work.

As shown in table 1, the CNWRA has 48 core and one limited-term staff members. He CNWRA updated the staffing plan portion of the Management Plan, reflected in table 1. He available pool of approved consultants and subcontractors declined to 46.

I his FYTD no capital or sensitive equipment was purchased with NRC funds (other than overhead,

general and administrative expenses, and fees).

6 O DWM JC He DWht JC cumulative cost variance through period 13 wa.7 percent. Expenditures in this JC increased by 2.6 percent over the previous period. Specific explanations for over/ underspending for COPS and each KTI follow.

The cost variance for COPS was 2.9 percent: 1.3 percent for the hianagement, Planning, and Computer Support subtask (1402-158) and 10.0 percent for the QA subtask (1402-159). Spending ,

J in the 158 subtask fell relative to last period but rose in the 159 subtask. In the next period, c. penses in the hianagement, Planning, and Computer Support subtask are expected to follow estimates, while those for the QA subtask are expected to be close to the estimated levels.

He cost variance for the IA KTI was - 14.0 percent. Spending is anticipated to remain stable in the ,

next period as FY99 OPS are implemented. )

The cost variance for the SDS KTI was -19.3 percent. Spending in the first period of FY99 is i anticipated to decrease slightly.

The cost variance for the ENFE KTI was 18.2 percent. This slight percentage reduction from period l 12 (18.9 percent) reflects payment of existing obligations.

The cost variance for the CLST KTI was 7.4 percent. He positive cost variance increased slightly relative to the previous period. The underspending results from being understaffed. The hiring of new staff will result in an increased rate of spending in the next FY.

l The cost variance for the TEF KTI was 18.9 percent. The underspending reflects reallocation of staff to other areas. His variance may decline in FY99 as newly hired staff work on TEF KTI activities.

The cost variance for the RDTh1E KTI was 12.0 percent. Spending increased in this KTI over the previous period. This variance may be reduced in FY99 as additional non-CNWRA staff work on KTI activities.

The cost variance for the TSPAI KTI was 14.9 percent. De variance may remain about the same, since the spending rate is expected to remain roughly constant during period 1 of FY99.

l De cost variance for t'ae ARDR KTI was 57.9 percent. Despite an increase in spending in period 13, this percentage variance is higher than the variance for last period. Dere is still no indication the draft EPA standard will be released for review in the coming months, so underspending will continue and may even increase during period 1 of FY99 unless new tasking is received.

The cost variance for the USFIC KTI was 12.1 percent, a slight increase from period 12 (11.4 percent). Spending declined over last period as the result of staff allocation to other assignments.

1 De final cost variance for the RT KTI at the end of FY98 was 10.8 percent, compared to 14.7 percent in period 12. This decreased variance is due to payment of existing commitments at the end of FY98.

He cost variance for the TWRS project was 4.8 percent. Aggregate underspending has resulted from the rescheduling of some FY98 milestones into FY99.

16

i s The cost variance for the TMI-2 ISFSI project was 14.0 percent-significantly lower than that of the previous period. This cost underrun will decrease as the CNWRA evaluates the DOE response to the NRC second round RAI and as resources are allocated for preparing the draft SER.

The cost variance for the DTS project was 28.9 percent-significantly lower than that of the previous period. This cost underrun was primarily because of delays in authorization of work and lack of continuity of funding during periods 3 through 6 in FY98. The cost underrun is expected to decrease after the DOE response to the NRC first round RAIis received and evaluated.

l The cost variance for the CISF project was 2.5 percent. Although per period spending declined this period, actual expenditures are close to the budgeted amount.

The cost variance for the PFSF project was 19.3 percent. This cost underrun will diminish as the CNWRA assists the NRC staff regarding the PFSF proceeding before the ASLB.

The cost variance for the SRSASF was 39.1 percent. Spending increased in period 13-resulting from the review of additional documents sent by the DOE.
