on the U.S. Department of Energy (DOE) Total Systern Performance Assessment-Viability Assessment and '

I the associated Technical Basis Document, and transmitted a Material Research Society manuscript. In  !

addition to preparing abstracts for presentation later this year, the staff produced joumal papers on Grain j Boundary Chemistry and Intergranular Corrosion in Alloy 825; Analysis of Drift Instability and Rockfall Due l to Earthquake Ground Motion at Yucca Mountain, Nevada: Effects of Repetitive Seismic Loads on l

Underground Excavations in Jointed Rock Mass; and also the results of experiments designed to determine l the repassivation potential of creviced A516 specimens as a function of the environment. These papers have >

been or will be submitted for acceptance in recognized technical journals. Staff panicipated in workshops, symposia, and other technical meetings.

The DWM JC year-to-date (YTD) cost variance was 18.9 percent. Spending rose from the previous period as a result ofincreased activity in CNWRA Operations and all but two key technical issues.

In the Tank Waste Remediation System (TWRS) JC, staff delivered a draft letter repon and a TWRS-Type Facilities Manual. In addition, staff continued preparation of various repons and the High-Level Waste Chemistry Manual, incorporating Nuclear Regulatory Commission (NRC) comments, as required. The YTD cost variance was 28.0 percent. Spending rose substantially from last period as staff, in addition to completing a draft report, developed and reviewed other reports and the chemistry manual.

In the Three Mile Island Unit 2 (TMI-2) Independent Spent Fuel Storage Installation (ISFSI) JC, the staff cor..inued revising the draft safety evaluation report (SER), responded to two sets of NRC comments, and reviewed the findings of DOE repons. The YTD cost variance for the TMI-2 ISFSI was -36.0 percent, resulting from continued effons to prepare the draft SER and other document reviews. Additional funds will be required to complete this work.

In the Dry Transfer System JC, staff reviewed the DOE response to the NRC first round request for additional information (RAI) and continued preparation of the draft SER. The YTD cost variance was 10.6 percent. Spending rose significantly from last period reflecting these activities.

In the Centralized Interim Storage Facility (CISF) JC, staff performed only preliminary review of the Seismic Topical Report on HI-STAR /HI-STORM cask systems. The YTD cost variance for the CISF was 34.7 percent. This underspending resulted from staff awaiting tasking to revise the computer code RISKIND and instruction to update the draft assessment repon.

In the Private Fuel Storage Facility (PFSF) JC, staff continued preparation of the draft SER and began review of the PFS response to the NRC second round RAI and site characterization repons. The YTD cost variance was -3.8 percent. Spending increased significantly as a result of these activities.

In the Savannah River Site Aluminum-Based Spent Fuel JC, the staff incorporated NRC coinments on a previously delivered report. No significant technical activities were conducted as the staff awaited receipt of additional documents from the DOE for review. The YTD cost variance was 74.1 percent. Although spending rose substantially compared with the previous period, the cumulative variance increased due to lack L of additional tasking in this project.

lt should be noted that the current spending estimates in all JCs are based on the assumption that staffing is t consistent with the aggressive hiring plan delineated at the time these operations plans were first develope'd in late FY1998. A revised staffing plan was presented in the Annual Review of the CNWRA that recognizes the slower than anticipated hiring through the first quarter. Current staffing remains below authorized levels and recruitment continues.  !

Training to be presented to identified NRC staff, and (vi) participate in a fact finding visit  !

with the DOE representatives in Las Vegas as authorized in the February 5,1999, i correspondence from NRC to CNWRA. j 1.2 Igneous Activity (IA)

Staff panicipated in two meetings with DOE contractor staff this period, to discuss i technical issues on models and data for igneous event probabilities and consequences.  !

These meetings represent significant advances toward DOE understanding and addressing [

NRC/CNWRA staff concerns with the TSPA-VA. An Appendix 7 meeting was held at SNL  ;

January 26,1999, which focused on the probability ofigneous disruption of the proposed repository site and likely characteristics of future YMR igneous events. Significant l accomplishments include developing an understanding that the PVHA average annual  :

I probability of 1.5 x 10 for intrusion disruption of the repository also corresponds to the probability of volcano formation at the site, based on due consideration of magma flowing  !

toward open repository drifts. Staff discussed tectonic models for the YMR and concluded l that the Crater Flat alluvial basin and YM are part of the same overall structural feature, at j scales likely to influence ascending basaltic magma. In addition, most Quaternary volcanoes j of the YMR (except Northern Cone and perhaps Black Cone) contain preserved features i I

commonly observed at historically active basaltic cinder cones that sustained violent strombolian eruptions. Consequently, a violent strombolian eruption style appears a i

reasonable assumption for the next YMR eruption. Additional work plans were developed i by the DOE staff to address uncertainties and concerns with TSPA-VA models of magma interactions with engineered systems. If implemented, these work plans represent a reasonable approach for the DOE to address current NRC staff concerns regarding models and data for igneous event risk assessments.

Based on review of the TSPA-VA, staff prepared input to the associated Commission paper.

The focus of there concerns is that analyses in the TSPA-VA could be used to screen volcanism from consideration as a disruptive event in subsequent DOE TSPA calculations.

Models used to conclude that the average annual probability for volcanic disruption is <10 8 do not meet the NRC acceptance criteria. In addition, models used to conclude significant resiliency of WPs during igneous events and limited HLW entrainment during volcanic eruptions also do not meet the VRC acceptance criteria. Informal staffdiscussions outlined previously may supercede the TSPA-VA conclusion that no additional work is needed on IA prior to licensing. Staff also contributed to KESA concerns on mechanical disruption of the WP, location and lifestyle of the critical group and dilution of radionuclides in soil.

This period, numerical and experimental models of magma-repository interactions were developed with the assistance of consultants from the University of Bristol. Numerical model development continues in a hierarchical fashion, based on the initial assumption of homogeneous equilibrium flow of the magma-gas mixture along the repository drifts.

Laboratory space at SwRI was secured to develop the physical analog model and perform the numerical experiments. Modifications to this space began. A high-resolution digital video camera was interfaced to a personal computer mnning Linux, which will capture the results of the physical analog experiments. Preparation continued for a journal article on analytical solutions to flow condition; during magma-repository interactions.

Staff prepared, and received NRC approval to submit, an abstract for presentation at the AGU Spring Meeting. The abstract is for a special session that focuses on models and uncertainties for geologic processes at YM. Staff will present the key models and data used in the NRC TSPA program to evaluate risks from future igneous events at YM. Results {

from current TPA calculations will be presented to place risks from igneous events m  ;

context with other apparent risks associated with the prcposed YM repository. 1 Also during this period, staff continued preparations for field work at the Cerro Negro volcano that will focus on processes controlling airborne resuspension of fine-grained ash from basaltic fall deposits. 1 1

In the next period, staff will finalize methods for sampling airborne particulates at the Cerro ;

' Negro volcano and conduct field ' investigations at the volcano site in Nicaragua. j Modifications to the physical analog laboratory at SwRI will be completed, a detailed  ;

outline of the structure of the numerical experiments will be completed, and construction  ;

of the experimental apparatus for magma-repository interactions will begin at the i University of Bristol.

Staff prepared summaries of SDS concerns related to five KESAs. The summaries were submitted to the appropriate KESA leads. Concerns raised in these KESAs were grouped and will be delivered as a single Al, in lieu of the SDS KTI deliverable, SDS Technica Input to Review of the DOE VA-Letter Report. The change in deliverables follows the KESA organization adopted by the NRC for VA review.  ;

Staff participated in a DOE /SNL workshop on disruptive events, which will be used by DOE to develop work plans for preparation of the LA. The workshop was held at SNL in Albuquerque, New Mexico. Staff also participated in a meeting to brief members of the ACNW on licensing concerns related to mechanical disruption of WPs. Staff also presented a poster at a symposium on dynamics of fluids in fractured rocks, sponsored by the LBNL in hanor of Paul Witherspoon's 80th birthday.

Start prepared for the upcoming DOE /NRC Appendix 7 meeting on PSHA, fracture and fault studies, and tectonic models. The meeting, which will be held March 2-3,1999, in Las Vegas, Nevada, and at the FOC, includes a half-day field trip to the cross drift in the ESF.

' Preparation continued on 3D Structural Model of Nonhern Amargosa Desen for Input to  ;

USFIC-CNWRA Report and on Structural Evolution of Crater Flat, Nevada-Journal Article. DOE PSHA and related documents were reviewed for Input to SDS IRSR, Revision 2, as were analyses of new TPA results on the sensitivity of repository performance to faulting.

Staff also modified the CNWRA Operations Plans for the Repository Program to account for the redistributed money and recently approved scope of work to analyz: the structural and stratigraphic framework of the alluvium in Jackass Flat and the Amart;osa Desen.

In the next period, staff vill attend the DOE /NRC Appendix 7 meeting on the DOE PSHA, fracture and fault studies, and tectonic models. Staff will prepare abstracts for the AGU Spring Meeting in Boston, Massachusetts. Staff will review the DOE VA, PSHA, and fault displacement hazard analyses report. Staff will construct the EarthVision 3D model of the Amargosa trough and prepare a journal anicle on the structural evolution of Crater Flat, Nevada. Staff will also analyze the sensitivity of repository performance to faulting. The report cor,taining the summaries of the SDS input to the KESAs will be submitted as an AI in the next period.

1,4 Evolution of the Near Fleid Environment (ENFE)

Staff pursued debugging, testing, and documenting MULTIFLO Version 1.2p. Work continued on the TVD transport algorithm in 2D and 3D. The TVD algorithm is required to reduce numerical dispersion, an anifact that can be amplified by chemical reactions.

i Errors in the calculations of the Jacobian matrix in the implicit time-stepping formulation were identified and corrected. These were causing slow convergence and excessive run times, but were not affecting accuracy of the results. A mesh generator based on Voronoi tessalation was obtained from LBNL and modified to provide input to MULTIFLO. This 4

.g I

pre-processor makes it possible to use the unstructured grid capabilities. Coding of the open-drift ventilation model began. i Application of the MULTIFLO code to coupled THC processes for the proposed repository environment advanced by testing kinetic phenomena with consideration of the carbonate

, and silica systems. Benchmarking MULTIFLO nonisothermal, kinetic chemistry results with EQ3/6 models propessed with attention to small discrepancies between the codes. A '

reinterpretation of UZ w ater chemistry was undertaken to establish initial conditions and i parameterization for the reodel that provide for relatively stable ambient conditions. j t

Staff continued review of the TSPA-VA Technical Basis document and the DOE VA. {

Comments were prepared to address relevant KESAs. These comments were transmitted  ;

to NRC as two KES A VA inputs: (i) Quantity and Chemistry of Water Contacting Waste .

Packages and Waste Forms and (ii) Radionuclide Release Rates and Solubility Limits.The DOE VA review has included preparation of statements on the status ofissue resolution at the staff level, making use of acceptance criteria in the ENFE IRSR, Revision 1.

i Aggressive efforts continued to advance activities by several consultants and SwRI staff on i subjects supponing the ENFE KTI, including evaluation of the potential effects of '

microbial activity, aqueous actinide chemistry, alteration of engineered materials on the near-field chemical environment, and properties of altered tuff materials. Activities are underway to initiate work with consultants on radionuclide releases, based on the Nopal I  !

analog studies and on the properties of cement phases at elevated temperature.

1 In the next period, staff will continue (i) reviewing the TSPA-VA Technical Basis l document and the DOE VA and (ii) debugging and benchmarking the MULTIFLO ccde. j Near-field radioelement solubility modeling and aqueous actinide chemistry studies will  !'

advance and sensitivity studies on the effects of cementitious materials will continue.

Preparations will be made for participation in the Natural Analogue Working Group Workshop scheduled for March 22-25,1999, in Strasbourg, France. These preparations include an Appendix 7 meeting with DOE on the Pena Blanca studies to be held March 8, 1999,in San Antonio, Texas. i 1.5 Container Life and Source Term (CLST)

Staff completed its review of the DOE VA for the proposed monitored geological repository in YM, Nevada. The review was conducted to identify major technical concerns and vulnerabilities in the VA c esign. These concerns, their technical bases, and the status of resolutions were summaris.ed and provided to the NRC for appropriate input to the pending Commission paper and its attachments. A more detailed' evaluation of other technical concerns will be presented in the CLST IRSR, Revision 2. A list of these concems, accompanied b3 a brief summary detailing the imponance and the status of resolution of each, was also delivered to NRC.

Cc currently, s

staff is preparing a report examining performance areas associated with ,

portial WP design alternatives. This report will summarize the materials, characteristics, and corrosion processes that may affect the major classes of materials considered for i

- base alloys, and titanium alloys. Degradation processes of Zircaloy cladding and ceramic  !

coatings will also be included in this report. The delivery of the report has been postponed i to June 1999 to include a review of the most updated DOE WP designs and the enhanced design alternatives for the EBS.

Electrochemical corrosion testing continued to confirm the applicability of repassivation j and corrosion potentials as predictive parameters for the long-term, localized corrosion of  ;

Allev 825 in chloride-containing solutions at 95 *C.The staffinitiated three long-term tests with Alloy 22 specimens. All three specimens have attached crevice forming devices and  !

are being tested in 4M Nacl at pH 8. One specimen is tested at open circuit so that the time  !

dependent changes in the corrosion potential can be monitored. Other C-22 specimens are held at applied potentials of 400 and 700 mVsce to determine the time required for crevice corrosion initiation as a function of potential. Although the staff does not anticipate that the i corrosion potential of the material will approach such high potentials under open circuit i conditions in air-saturated solutions, the purpose of these tests is to determine the initiation  ;

time for crevice corrosion of C-22 in concentrated Nacl as a function of potential and the applicability of using the repassivation potential to predict localized corrosion initiation.

In addition, two of the long-term tests using Alloy 825 continued. In one of the tests, a specimen is exposed at the open circuit potential in an air-saturated chloride solution. In the j other test, the specimen is maintained at 50 mV below the repassivation potential. I SCC tests continued on Alloy C-22 and type 316L SS. Fatigue precracked, wedge-loaded l specimens of each material have been immersed in a deaerated 5 percent Nacl solution, 4 acidified to pH 2.7 by the addition of hcl, and heated to 90 *C to duplicate the conditions used at the LLNL. Tests on Alloy C-22 used an initial stress intensity of 33 MPa m'*, while <

the type 316L SS specimens were tested at an initial stress intensity of 25 MPa min. No f cracking was observed under these conditions for a cumulative test time of 12 wk. In  ;

addition, no crack growth was observed on Alloy C-22 specimens tested in 40 percent .

MgCl 2at 110 *C for 12 wk. Staff used redesigned specimens to allow testing of both  !

welded and nonwelded material at higher stress intensities.

A paper titled Grain Boundary Chemistry and Intergranular Corrosion in Alloy 825 has l been prepared for publication in Materials Transactions. This IM will be added to the list l of deliverables in the current OPS. The paper described and analyzed the results of research  !

performed in previous years and was completed using a small expenditure of staff time  ?

during this FY. l The staff is examining the key environmental variables affecting the corrosion behavior of A516 carbon steel and the critical values of these variables in determining the occurrence  ;

oflocalized corrosion. In particular, the pH, chloride concentration, temperature, and redox  ;

potential are being examined. Work continued on examining whether localized corrosion i of A516 can occur under open circuit conditions in air-saturated solutions. Experiments l designed to determine the repassivation potential of creviced A516 specimens as a function t of environment also continued. A paper detailing these results was submitted for  ;

presentation at the 1999 NACE International Annual Corrosion Conference and is planned 6 ,

.L for inclusion in the proceedings. Another paper presenting additional information and data is under preparation for publication in Corrosion.

l Specimens and material for testing titanium grade 7 have been ordered, as this is .- pusible candidate material for WP construction being evaluated by LLNL. Weldeci specimos, included in the order, will be used to examine the potential detrimental influence af weldments on corrosion performance.

In the next period, long-term corrosion tests of Alloys .825 and C-22, together with SCC tests using Alloy C-22 and type 316L SS, will continue. Most of the experiment 9 e~lvities planned for A 516 carbon steel will be completed in the next period. The paper entitled Grain Boundary Chemistry and Intergranular Corrosion in Alloy 825 will be submitted as an IM.

1.6 Thermal Effects on Flow (TEF)

Numerical analysis of the DST continued during tl.is period.The matrix / fracture coupling term is beNg modified to increase the degree of hydraulic connectivity between the matrix and fractua continua, thus obviating the buildup of gas pressure near the heat source. This has the compromising effect of making the DCM more like an ECM and minimizing the prospect of gravity drainage down the fractures. LBNL models of the DST are based on an equivalent continuum conceptualization.

l The second phase of the laboratory-scale boiling isotherm depression heater experiment I continued during this period. The originally planned completion of this experiment, the end l of January 1999, has been postponed. Continued moisture and temperature evolution in the I test cell suggests that a steady state has not been attained yet within 4 mo of heating, as was the case in the first phase of the experiment. The second phase will proceed indefinitely to observe the continued heat and mass evolution.

Staff continued the mountain-scale repository analyses. These analyses are extensions of earlier repository-scale nonisothermal analyses of perched water. The current analyses will investigate an EW-trending, vertical 2D geologic section midway through the repository block. These analyses use the MULTIFLO code with a dual-continuum conceptual model.

Staff participated in the quarterly DOE Theimal Test Workshop held at the LBNL January 29,1999. The Alcove 5 single-heater test is considered complete and was not discussed at this quarterly workshop. A trip report recounting the workshop was transmitted  !

on February 9,1999.

l Staff initiated a review of literature to identify potential analog sites for the evaluation of water seepage from fractures into open drifts in the UZ. DOE also launched a review of potential analog sites and indicated a willingness to keep NRC/CNWRA informed on a timely basis of progress in this area.

Investigation of capillary diversion at the drift walls continued during this period. A laboratory-scale experiment designed to resolve the distinction between capillary diversion 7

t and dripping has been initiated. A profilometer is being used to map the topography of the ,

fracture surface. It is not certain whether the resolution of the profilometer is sufficient t'o provide detailed mapping of the fracture tooography. l Staff provided review comments on the TSPA-VA Technical Basis document and the  ;

TSPA-VA. These comments reflect a high order review at this time. Detailed review comments will be included in the next revision of the TEF IRSR. The delivery date for the next revision of the IRSR has been moved from July 30,1999, to May 17,1999.

t Discussions have continued with consultants and SwRI staff to identify tasks on which they can participate in resolving concerns associated with dripping. Work has proceeded on integration of a groove / film flow model into the mechanistic fracture flow model. Draft reports describing the status of this work have been prepared. Efforts continue on evaluating institutional COI with respect to Columbia University. A draft SOW for Columbia to evaluate correlations between dripping and fracture characteristics is in preparation. A task has been initiated with SwRI staff to formulate an analytical solution for flow fmm a fracture into an open drift. Results from this solution will be compared with the resul; from the laboratory-scale fracture flow experiment.

In the next period, TEF KTI staff plans to (i) continue the second phase of the boiling isotherm penetration laboratory-scale experiment, (ii) continue a literature search for l potential dripping analog sites,(iii) test the MULTIFLO-DCM numerical code in modeling the DOE DST, (iv) continue.the integration of a groove / film flow model into the mechanistic fracture flow model, (v) initiate a subcontract with Columbia University to i investigate dripping / fracture correlations, and (vi) initiate the next revision of the TEF IRSR. j Repository Design and Thermal-Mechanical Effects (RDTME) 1.7 f

The UDEC analyses to predict the size and extent of rockfall under seismic loads in the repository thermal environment continued during this reporting period. The fundamental process of damping and wave transmission throughjointed medium handled by the UDEC code are being evaluated. Staff began an effort to compare the dynamic analyses using UDEC and KDYNA 3D to examine rockfall. This effort is to gain confidence in UDEC results. A paper titled Analysis of Drift Instability and Rockfall Due to Earthquake Ground Motion at Yucca Mountain, Nevada was delivered on January 22,1999 as Process-Level Rockfall Study for Input to SEISMO Module of TPA Code-Conference Paper.

The ABAQUS modeling of WPs continued to investigate the thermal stress of WPs and also assess WP responses when subjected to the impact of falling rocks at various times.

The ultimate goal is to develop a reasonable failure criterion to be used in the SEISMO module to assess the effect of rockfall on WP integrity.

Staff pursued the development of the review plan for preclosure aspects of design, construction, and operations of the repository using the integrated safety assessment methodology.

jb Staff studied the behavior of the rock mass surrounding the emplacement dr:fts under heated conditions at the repository scale using ABAQUS.This study emphasizes rock mass behavior beyond the preclosure period and effects of thermal load on permeability changes in the surrounding rock mass.

Staff began the thermal-mechanical study of drift stability in the area where the transition from strong to weak rock occurs. The objective of this study is to determine whether a

synergistic effect exists that could adversely affect drift stability in this area under thermal conditions.

Staff reviewed literature on concrete performance at high temperature to provide valuable i information to assess the DOE design of the concrete liner for use at high temperature.

Review of the TSPA-VA related to the Mechanical Disruption of Waste Packages KESA and the design of the repository were submitted on February 4,1999. Input for the potential effect of long-term drift stability on near-field flow and geochemistry was also provided by a staff member to the Quantity and Chemistry of Water Contacting Waste Packages and Waste Forms KESA.

One RDTME KTI staff member attended the DOETSPA Disruptive Events Workshops on Seismic Activity, Febmary 10,1999,in Albuquerque, New Mexico. A paper titled Effects of Repetitive Seismic Loads on Underground Excavations in Jointed Rock Mass was submitted for presentation at the' 7* International Conference on Radioactive Waste Management and Environmental Remediation scheduled for September 26-30,1999, in J Nagoya, Japan.

In the next period, RDTME 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 ABAQUS code to model WPs, and (vi) develop the standard review plan.  !

1.8 Total System Performance Assessment and Integration (TSPAI)

Staff reviewed the TSPA-VA and prepared a letter report entitled Review of Final Viability  !

Assessment and Preparation of Comments' for Commission Paper. Staff identified l inadequate transparency and traceability of TSPA-VA calculations as a concern that may l warrant inclusion in the Commission paper and documented other cross-cutting issues in  !

.TSPA-VA that might be addressed at DOE /NRC technical exchanges, Appendix 7, or  !

similar meetings. Staff developed a preliminary ranking of KESAs based on parameter sensitivity analyses, importance analysis, and staff expertise. Major differences between  ;

DOE and NRC TSPA modeling approaches, input parameters, and maj or assumptions were l

documented. Conducting TSPA runs continue to compare DOE results and NRC outputs j using the base case data set.  !

Staff discussed with members of the ACNW the NRC/CNWRA review of the TSPA-VA.  ;

VA. All agreed that although the TSPA-VA was much better than 'ISPA-95, TSPA-93, and ,

TSPA-91, it is difficult to trace the evolution of certain quantities or measures through tiie TSPA-VA.The meeting helped crystallize NRC thinking on the clarity and reproducibility of the TSPA. A block-diagram approach displaying the intermediate and final outputs of the TSPA-VA is likely to be proposed to the DOE. i l

Staffinitiated a cleanup of the TPA Version 3.2 code that will be released to the pubhc as f an executable. To prepare for public release of the TPA code, a suite of specialized cases l was developed to test the executable of the TPA Version 3.2 code. j A manuscript was prepared outlining the general parameter tree approach and its feasibility.  !

The manuscript will be delivered as an AI and is currently undergoing intemal technical  !

and programmatic reviews.

Data generation for sensitivity analyses using the TPA Version 3.2 code continued, and l code testing was conducted on an as-needed basis. Support was provided to the NRC staff  ;

report as a NUREG. j

- Staff began merging the PVM, PC, and SUN Solaris versions of the TPA Version 3.2 code into a single code to reduce the costs of code maintenance. All changes will be documented  !

in the software change request forms as required by TOP-018. These changes will not be j a part of the SRD being developed for the next version of this code.  ;

I Staff completed a literature review on instrumentation for collecting and measuring  !

suspended ash particle size distributions at the Cerro Negro volcano in Nicaragua. The {

collected data will be used in refining the AML factor for the DCAGS module of the TPA  !

Version 3.2 code, which is used in estimating inhalation doses due to radionuclides released l

' by extrusive volcanism. i Eight candidates were identified to serve as external reviewers of the TPA Version 3.2 [

Detailed modeling continued to evaluate the effects of well characteristics and plume I dimensions on the accuracy ofestimates of doses from the groundwater transpon pathway.

Some difficulties were encountered regarding the selection of appropriate software for numerically modeling flow and transport. After considering various options, a decision was made to use BIGFLOW to simulate groundwater flow and SLIM 3 to simulate es transport. BIGFLOW does not explicitly account for pumping wells, so some modifications were implemented. Evaluation of these modifications will continue in the next period.  ;

Assuming no further complications, a report will be completed by the end of June 1999.

Review continued of the DOE VA to support development of a Commission paper. The staff completed reviews of those VA chapters that pertain to KESAs relevant to ARDR activities (i.e., location and lifestyle of the critical group and dilution of radionuclides in soil).The review emphasized staff analysis of DOE BDCFcalculations. During this period, two Al reports summarizing CNWRA results of the VA review for the two relevant KESAs was delivered.

Investigation continued on topics pertaining to calculation of age-specific doses at YM. A new (final) EPA report was obtained that contains a large body of age-specific intake information. The EPA information was reviewed and the best available age-specific consumption rates for a variety of food groups were selected for the dose analyses. Some initial calculations were completed and more detailed modeling with the GENII-S code is l planned for next period.

Revisions to the previously issued report,Information and Analyses to Support Selection of Critical Groups and Reference Biospheres for Yucca Mountain Exposure Scenarios, completed internal review. The revised report is an IM that will be issued as a ,

NUREG/CR-a key reference document for the rulemaking effort and TSPAI activities. I i

In the next period, staff will complete preliminary BIGFLOW and SLIM 3 runs as pan of the borehole dilution study. Testing of needed modifications to BIGFLOW will continue.

Assessment of age-specific DCFs will continue with detailed modeling in GENII-S using age-specific consumption rates documented in a recent EPA repon. As ajoint effort with the TSPA KTI, staff also will begin investigating the feasibility of an improved (stochastic) dose module for the TPA code to replace the lookup table approach currently in use. lf the draft EPA Standard is published, staff will assist the NRC with reviewing it and preparing ,

comments. The revised repon, Information and Analyses to Suppon Selection of Critical I Groups and Reference Biospheres for Yucca Mountain Exposure Scenarios, will be delivered during next period.

J will be used to constrain infiltration and groundwater flow models in Crater Flat.

A geophysical survey was conducted in the Amargosa Region and Fortymile Wash. The  !

goals of the survey were to (i) map the water table elevation, (ii) map subsurface geological i structures, and (iii) possibly map the tuff / alluvium contact along Fortymile Wash. The l geophysical techniques included time domain electromagnetics using an EM-47, standard i Schlumberger resistivity measurements, and time domain induced polarization. In total,33 EM-47 soundings,4 time domain induced polarization, and 4 standard Schlumberger resistivity soundings were performed. To support the interpretation of the survey data, l water table data and geological data from available sources have been collected. These  :

sources include the available wells (new Nye County wells and wells on the NTS) and other l geophysical data sets. Postprocessing and preliminary analysis of the data began.  !

Preliminary results at some of the survey locations indicate the presence of multiple  !

resistive layers beneath the alluvium; the layers have not yet been correlated to geologic units.

1.11 Radionuclide Transport (RT)

Staff completed formal review of the DOE VA and transmitted input to NRC KES A leads.

Review comments were prepared and organized according to the KESA structure; two i KES As directly related to the RT KTI included Retardation in Fractures in the Unsaturated Zone and Retardation in Water-Production Zones and Alluvium. Several technical concerns were identified, including matrix diffusion in the UZ, the possibility of colloidal transport of radionuclides other than plutonium, consideration of transport of a limited list of nine radionuclides, and the lack of site-specific information on alluvium.

Two abstracts were prepared and submitted for presentation at the Seventh International  ;

Conference on the Chemistry and Migration Behavior of Actinides and Fission Products '

in the Geosphere-Migration '99 to be held September 26--October 1,1999, in Lake Tahoe, Nevada. The first abstract, Uranium (VI) Sorption Behavior on Mixed Silicate Minerals, describes preliminary results from mixed-mineral sorption experiments currently being conducted at the CNWRA.The second, Modeling Colloid Transport for Performance Assessment, prepared in collaboration with NRC staff, presents the resuhs of sensitivity analyses using the TPA Version. 3.2 code to investigate the effects of colloid transport.

This abstract also summarizes the results of the abstraction of detailed modeling of pseudocolloid transport using site-specific information. Preparation continued on a manuscript developing a stochastic analytical interpretation for early tracer arrivals in multiple fracture pathways.

Uranium sorption experiments on mixed minerals (clinoptilolite and quartz) continue. The experiments are conducted over a range of pH in solutions with an initial U(6+)

4 concentration of 2.0 x 10 M.The amount of quartz added to experimental solutions is kept constant at 28 g/L, whereas the amount of clinoptilolite is varied from 0.0 to 20 g/L.

Experiments continue using solutions in equilibrium with atmospheric CO2(g) and solutions having limited CO 2(g). Experiments with 0.0,1.0, and 10.0 g/L clinoptilolite are complete.

Experiments with 20.0 g/L clinoptitolite are in progress. During this period, a controlled atmosphere glove box was set up for use in experiments conducted under limited CO2 (E) conditions. Staff continued development of laboratory procedures for neptunium-alluvial 13 l

In subtask 2.2, the staff will continue analysis on IPs 35016 and 35060 and forward draft procedures for review. These IPs are due March 31,1999.

I,13 Three Mile Island Unit 2 Independent Spent Fuel Storage Installation (TMI-2 ISFSI)

Revision of the draft TMI-2 SER continued during this reporting period. This revision is based on the resolution of two sets of comments made by SFPO technical staff and management, together with the review findings of the DOE reports on structural evaluation of TMI-2 ISFSI basemat and those on site transfer from TAN to INTEC. Because of the receipt delay in the second set of SFPO comments on the draft TMI-2 SER, delivery of the final SER was rescheduled from February 8 to February 26,1999.

In the next period, TMI-2 ISFSI staff plans to complete preparation of the final SER and assist the NRC staff to prepare TMI-2 ISFSI Materials License No. SNM-2508.

I.14 Dry Transfer System (DTS)

The DOE response to the NRC first round RAI was received during this reporting period.

Review and evaluation of the DOE response and development of the second round RAI were initiated. Preparation of the draft SER continued this reporting period at an extremely slow rate.

In the next period, DTS staff plans to continue review and evaluation of the DOE response to the NRC first round RAI, develop the second round RAI, and prepare the draft SER.

1.15 Centralized Interim Storage Facility (CISF)

Because oflack of assignment, only preliminary review of the High Seismic Topical Report on HI-STAR / HI-STORM cask systems continued this reporting period.

In the next period, CISF staff plans a technical review of the Seismic Topical Report on HI-STAR /HI-STORM cask systems while awaiting instmetion to revise the draft AR and the computer code RISKIND.

SUMMARY

OF FINANCIAL STATUS l Table 4 summarizes the CNWRA financial status in the context of authorized funds. Total commitments are $374,073.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 cumulative basis. These data do not include commitments. Pertinent financial iriformation is provided for the DWM JC, including COPS and 10 KTIs, TWRS JC, TMI-2 ISFSI JC, DTS JC, CISF JC, PFSF JC, and SRS ASF JC. The 1 planned costs per period are based on the revised spending plans contained in the current operations j plans.

It should be noted that the current spending estimates in all JCs are based on the assumption that  !

' staffing is consistent with the aggressive hiring plan delineated at the time these OPS were first i developed in late FYI998. A revised' staffing plan was presented in the Annual Review of the  !

CNWR A that recognizes the slower than anticipated hiring through the first quaner. Current staffing  !

I remains below authorized levels and dedicated reemitment continues. The CNWRA has continued l to update the staffing plan presented during the November 18,1998, CNWRA Annual Program i Review.

Period 5 FY1999 CNWRA composite expenditures rose 36.3 percent from the previous period, and l this aggregate of all JCs was underspent by $%3,081 or 18.9 percent. When comparing period 5 l

with last period, the DWM, TWRS, TMI-2 ISFSI, DTS, PFSF, and SRSASF JCs evidenced higher spending levels while only the CISF JC showed a lower level. l l

The DWM JC was underspent by $826,372 or 18.9 percent. Overall expenditures increased l

27.5 percent from the previous period as costs rose in COPS and the IA, SDS, CLST, TEF, TSPA,

~

ARDR, USFIC and RT KTIs but declined in the ENFE and RDTME KTIs. Costs to date are i 32 percent above those a year ago, and period 5 costs are also 32 percent greater than the same  ;

period last year. Despite the FY1999 budget being 24 percent greater than FY1998 and the FY1999 {

year-to-date cumulative variance 74 percent higher than that for FY1998, initiation of the augmented l l

scope of work, coupled with the aggressive recruitment of core staff and the engagement of  !

consultants and subcontractors, provides an encouraging outlook for the CNWRA to attain its spending targets.

f j

i The TWRS JC was underspent by $104,508 or 28.0 percent. Spending increased substantially from l l the previous period as the staff delivered a draft letter report and prepared the HLW Chemistry I

j Manual and other reports.

I l The TMI-2 ISFSI JC was overspent by $33,218 or -36.0 percent. Spending rose from last period.

l l Costs continue to reflect the focus on the revision of the draft SER-responding to two sets of i comments from SFPO staff-and the review of supplemental DOE reports. Additional funds will j be allocated to support completion of this work.  !

The DTS JC was underspent by $6,896 or 10.6 percent. Expenditures increased significantly from the previous period, reflecting staff review of the DOE response to the NRC first round RAI and '

preparation of the draft SER.

The CISF JC was underspent by $28,435 or 34.7 pement. Spending again decreased by one half compared with the previous period because the lack of assignments resulted in the staff performing only preliminary review of the Seismic Topical Report on HI-STAR /HI-STORM cask systems.

The PFSF JC was overspent by $1,956 or -3.8 percent. Expenditures increased substantially from the last period. In addition to staff preparing the draft SER, they engaged in the review of the PFS response to the NRC second round RAI.

The SRSASF JC was underspent by $32,043 or 74.1 percent. Spending rose from last period with 3

the incorporation of NRC staff comments on a previously delivered report.

s Expenditurt on SwRIlabor, consultants, and subcontractors as a proportion of composite spending on all JCs were 18.2 percent. Expense of consultants and subcontractors as a fraction of composite spending on all JCs was 10.5 pement. The CNWRA remains committed to enhance, where l appropriate, participation of consultants and subcontractors in the conduct of CNWRA work.

G. ,;

i As shown in table 1, the CNWRA has 53 staff members. The available pool of approved consultants

' l and subcontractors is 36.  !

i This FYTD no capbl or sensitive equipment was purchased with NRC funds (other than overhead, l general and administrative expenses, and fees).  ;

DWM JC The DWM JC cumulative cost variance was 18.9 percent. Expenditures in this JC increased by 27.5 percent compared with period 4. Specific explanations for over/ underspending for COPS and each KTI follow. t The cost variance for COPS was 18.8 percent: 17.8 percent for the Management, Planning, and  !'

Compuier Support subtask (158) and 23.0 percent for the QA subtask (159). Spending in both subtasks rose relative to last period and, for subtask 159, reflects the highest per-period expenditure since the beginning of this FY. Spending on labor and Other Direct Costs increased from the  ;

previous period. In the next period, spending in subtask 158 should remain close to estimates, contingent on acquisition of a clerical staff member, sustained use of computer-related consultant (s) to upgrade the CNWRA management information systems, and participation of eligible staff in l professional development activities. In subtask 159, spending should remain somewhat below  ;

estimates until preparations begin, usually in period 7, for the annual QA audit and QA training is j accomplished. Preparations continue for scheduling the training of the NRC staffin accordance with the augmented scope of work in subtask 159.

The cost variance for the IA KTI was 3.9 percent. Spending increased slightly from the previous l period, and modest underspending is expected to continue through the next period until expenses  !

associated with planned field investigations are paid.

l The cost variance for the SDS KTI was 0.4 percent. Spending rose compared with last period, and i the rate will increase modestly in periods 6 and 7 as charges for upcoming field work and increased l consultant use are paid.  ;

1 The cost variance for the ENFE KTI was 30.6 percent, a slight decrease in percentage variance from period 4. Reallocation of funds is expected to significantly reduce this variance during the next period. For at least the next several periods, a positive variance is expected. In the future, new work on cement properties and Pena Blanca studies are anticipated to significantly reduce the variance. i It remains uncertain when the contracts will be fully executed and at what dates the costs associated I with this new work will be posted to the account; however, these matters are being pursued aggressively. I The cost variance for the CLST KTI was - 11.9 percent. The VA review, addition of another staff member, and purchase of new materials and supplies to investigate corrosion of LA design materials l maintained the spending above the current budgeted amount. It is anticipated that spending will be j close to the revised budget once the allocation of additional funding to the CLST KTI becomes  !

effective next period. '

18

The cost variance for the TEF KTI was 23.9 percent, with spending this period significantly higher than that of the previous period. The total FY 1999 cost undermn through this reporting period is due to temporary assignment of CNWRA staff from the TEF KTI to other higher priority projects.

Several consultants and SwRI staff members are currently working on TEF KTI tasks, and discussions are ongoing with several other prospective consultants regr.rding involvement in these tasks. The cost underrun will decrease during the next few periods because of anticipated increased consultant participation in TEF KTI activities and expectation of newly hired staff working on these l activities.

The cost variance for the RDTME KTI was 11.3 percent. Spending during periods 4 and 5 rose  !

substantially over periods 1-3 but was insufficient to meet the 35 percent increase in planned costs associated with the augmented scope of work. Now that two consultants, one subcontractor, and one SwRI staff member are working on RDTME KTI tasks, including augmented work, the expenditure j will increase significantly. Actual expenditures are expected to continue following the budget for l this KTI, however, some cost underrun is expected during period 6 related to the probable lagging )

charges from consultants and subcontractors. I The cost variance for the TSPAI KTI was 29.6 percent, little changed from the previous period despite a substantive increase in spending. The cost variance for period 6 is likely to remain the same unless the augmented work on development of a TPA post-processor is initiated.

The cost variance for the ARDR KTI was 59.5 percent. This variance is similar to that in the last period. There is still no indication the draft EPA Standard will be released for review in the coming months, so underspending will continue indefinitely. The augmented scope of work has the potential to control underspending, but timely actions regarding the public outreach program are essential to achievement of this goal.

The cost variance for the USFIC KTI was 11.4 percent, a slight decrease in percentage variance from period 4. Costs for recently completed field work are anticipated to significantly reduce this variance. Nevertheless, a positive variance is expected until additional hydrogeology staff are hired and start work.

The cost variance for the RT KTI was 35.5 percent. This slight decrease in percentage variance relative to period 4 spending resulted as additional staff continued to review the VA. The planned

addition of a laboratory technician together with invoices from ongoing and planned work by l consultants are anticipated to reduce the variance somewhat in coming periods.

l The cost variance for the TWRS project was 28.0 percent. It is anticipated spending will continue at this rate in the next period. A meeting has been scheduled with the NRC on February 18,1999, l to augment the current scope of work. The staff effort is being augmented through the judicious use l of consultants and SwRI staff to achieve timely completion of milestones.

The cost variance for the TMI-2 ISFSI project was -36.0 percent. This overspending resulted from concentrated efforts during the first three periods of FY1999 to prepare the draft SER and in periods 4 and 5 to revise this draft as the final SER. Approximately 95 percent of the FY1999 tasking within the TMI-2 ISFSI project was completed during periods 1-5. As a result, the cost overrun will decrease signifiently in the next few periods because of reduced activities. An additional $20,000 19

3.-

C. ,

has been authorized to accommodate the extra effort to resolve the SFPO second set of comments l received after preparation (but not delivery) of the final SER, etich was based on the first set of [

- SFPO comments. FY1999 total expenditures are expected to converge to the FY1999 revised ,

' allocation.

{

The cost variance for the DTS project was 10.6 percent, significantly higher than that of the previous }

period. This cost underrun is due to delay in receiving the DOE response to the NRC first round "

RAI. Now that this has been received, expenditures are expected to increase signific. ntly and remain high for several periods to accomplish the review and evaluate the DOE response, develop the  ;

second round RAI, and prepare the draft SER. As a result, a temporary cost overrun will occur, but 1 the FY1999 total expenditures are expected to converge to the FY1999 allocation.

[

The cost variance for the CISF project was 34.7 percent, which reflects sharply decreased costs following transmittal of a key report. This cost underrun will continue until CNWRA receives i instruction from the NRC on the desired scope for revising the computer code RISKIND, revising l the draft AR, and reviewing the Seismic Topical Report on HI-STAR /HI-STORM cask systems. l i

The cost variance for the PFSF project was -3.8 percent. The expenditures will increase i

significantly and remain high for the next few periods to accommodate review of the PFS response, study of the site characterization reports, and prepare the draft SER. As a result, a temporary cost .  !

overrun will occur but the FY1999 total expenditures are expected to converge to the FY1999 allocation. .

The cost variance for the SRSASF was 74.1 percent with essentially no costs incurred in the previous period. The review of additional DOE reports will commence in the next period, which will increase the spending rate.  !
