BY B. JOHN GARRICK = l1 I LE MINUTES OF THE 97TH MEETING OF THE ADVISORY COMMITTEE ON NUCLEAR WASTE DECEMBER 16-18, 1997 ROCKVILLE, MARYLAND {

l I

J The Advisory Committee on Nuclear Waste (ACNW) held its 97th meeting December 16-18. 1997, at Two White Flint North, Room T-283, 11545 Rockville Pike.

Rockville. Maryland. The ACNW met to discuss and take appropriate action on the items listed in the attached agenda. The entire meeting was open to i

\

public attendance.

A transcript of selected portions of the meeting is available in the Nuclear Regulatory Commission (NRC) Public Document Room at the Gelman Building. 2I20 i L Street. NW.. Washington, DC. Copies of the transcript are available for purchase from Ann Riley & Associates. Ltd., 1250 I Street. NW.. Suite 300, Washington, DC 20005.

[ Richard K. Major was the Designated Federal Official for this part'of the meeting.)

Dr. Garrick noted a number of items that he believed to be of interest regarding the drift scale heater test which began on December 3,1997, at the Yucca Mountcin Project. He also stated that the former Westinghouse Electric Corporation, now known as CBS Corporation, is seeking buyers for both its Savannah River site operating contract and its commercial nuclear fuel plant near Columbia, South Carolina. He stated that the Southeast Low-Level Compact Commission voted to suspend funding for development of a proposed low-level waste (LLW) site in the state of North Carolina. Dr. Garrick said that the NRC is concerned because $7 million spending shortfall is projected for May 1999. Another item of interest was that 26 utilities have petitioned a Federal appeals court to permit them to stop making payments to the Department of Energy (DOE) for the Federal Nuclear Waste Fund because DOE has not honored a legal requirements to begtn taking spent commercial nuclear fuel.

{ 97th ACNW Meeting 3 December 16-18,1997 II. Health Effects from Low Levels of Ionizino Radiation (Oceni

[Mr. Howard J. Larson was the Designated Federal Official for this part of the meeting.]

Dr. Wymer introduced this topic by noting that it had been presented to l several members of the Committee during a joint ACNW-ACRS meeting held in March 1996. As a result of that meeting, the Committee issued a letter to the Commission dated July 10, 1996. After noting that this session was scheduled to take the entire morning, he introduced the first speaker Dr. Myron Pollycove, Visiting Medical Fellow. Office of Nuclear Materials Safety and Safeguards (NMSS).

Dr. Pollycove's presentation, entitled " Molecular Biology Epidemiology, and the Demise of the Linear No-Threshold (LNT) Hypothesis." covered the follow-ing:

1. the November 17-21, 1997, international conference held in Seville.

Spain, titled " Low Doses of Ionizing Radiation: Biological Effects and Regulatory Control":

2. the August 1-3, 1997. Wingspread conference in Racine, Wisconsin.

which discussed " Cancer Risk from Radiation Exposures" [Dr. Pollycove noted that neither conference had attained a consensus]:

3. studies of exposures to various populations, namely:

., Y 97th ACNW Meeting 4

. December 16-18,1997

a. a study of the Eastern Urals villagers,
b. a study of Japanese radon baths,
c. a U.S. residential radon study,
d. a U.S. nuclear shipyard worker study,
e. the Canadian breast fluoroscopy study,
f. the Japanese life span study (1950-1990), and
g. the Rocketdyne worker study; and
4. technical molecular biology considerations relating these studies to DNA damage and repair systems and the response of the immune system to radiation.

f In summarizing his presentation, Dr. Pollycove cited the National Council on Radiation Protection and Measurements (NCRP) as stating very correctly that the LNT is a bio-physical presumption, not a biological one, and that 'ulti-mately, confidence in the linear, no-threshold (LNT) dose-response relation-ship at low doses is based on our understanding of the basic mechanisms involved."

Dr. Hornberger asked whether 20r could be considered an acceptable threshold level, to which Dr. Polixove responded that although at the Wingspread conference it was stated that no significant damage was observed below 20r, he personally would be quite content with a ir threshold level.

Dr. Holahan provided an update on the status of two NRC-sponsored projects:

the NCRP Subcommittee SC 1-6 study on the LNT theory, and the study in progress by the National Academy of Sciences on the potential efficacy of l

97th ACNW Meeting 5

December 16-18,1997 producing a BEIR VII study on the effects of low levels of ionizing radiation.

He noted that the SC 1-6 group had met five times thus far. Scientists on both study groups have expressed a need for more data indicating that there is insufficient data on the epidemiological side and that "it's beyond the envelope" of currently available relevant cellular and molecular biology studies.

The SC 1-6 subcommittee members have individual work assignments. In addition, the subcommittee has received input from some 42 individuals in response to a call for information from the scientific community. SC 1-6 has met four times and has held a public workshop in which 20-25 individuals were invited to address the group. There will also be an opportunity for a finite group from the public to provide input to the subcommittee next spring. It is anticipated that the draft report will be available by the end of 1998. with the final report expected in the 1999 time frame.

Dr. Holahan also provided additional information on the National Research Council / National Academy of Sciences report, stating that the study seeks to determine whether sufficient new data has been generated in the last decade to permit a reassessment of the BEIR V report data. New data has been generated by the Russian Techna River and Mayak production worker studies, followups to the atomic bomb study, and the potential dosimetry changes associated with the Hiroshima bomb. The study group is doing a scoping study, with several points stressed, viz., low-dose exposures (in the range of 1 to 100 millirem above background), and the potential for decreasing the uncertainty in the estima- H tion of the dose and dose-rate reduction factors. The group is interested not only in organism thresholds but also in organ thresholds and recognizes that 1

j

I k., ,,

l 97th ACNW Meeting 6 December 16-18,1997 among other things. it must consider genetic predisposition, the influence of adaptive response, and the potential for radiation hormesis.

l Subsequent to their last meeting, the BEIR VII group met to discuss its preliminary recommendations and conclusions. Two reports are relatively imminent: the first is a letter report, expected to be issued in the next few weeks. in response to questions from the Environmental Protection Agency (EPA). EPA asked: if a recommendation were to be made to develop a BEIR VII.

what should the scope of work be? What type of issues should the committee address? What type of expertise would be needed? The second report is the final recommendation and should be available, perhaps, in the mid-February time frame.

Dr. Garrick asked why sufficient exposure data had not been generated over the years. In his opinion. it would appear that a sufficiently large database for resolving the question of the biological effects of low levels of ionizing radiation should have been generated by now. In response. Dr. Holahan noted toat there are many who believe that there are too many questions to permit obtaining an answer from the epidemiology, and currently the molecular tools are not sensitive enough.

Dr. Shlomo Yaniv. Office of Nuclear Regulatory Research, provided information on several of the studies underway in the former Soviet Union, such as on the 1 effects among the workers in Mayak on the population along the Techna River, and on the 1957 waste tank explosion. Results of those studies are not expected for another 5 years. He also noted the studies of thyroid cancer among children exposed during the Chernobyl accident and the feasibility study 1

of leukemia among the liquidators (the cleanup workers) Dr. Yaniv stated that these studies in Russia are opportunistic in that they are based on human data, as opposed to many of the current models in use today, which are based on animal experiments and extrapolations.

Dr. Carl Paperiello, Director, NMSS, discussed several aspects of the regula-tory perspective of the LNT theory. He expressed concern with the current polarization of opinion of those in the health effects field as to the applicability or nonapplicability of the current LNT theory. The question he posed was how to get those concerned with the issue to quit debating it and focus on getting the needed answers. He believed epidemiology, for the very low doses, would not prove the linear model. He also thought that the data based on the Russian experiences might help better define the dose rate effectiveness factor. Dr. Paperiello expects that the answer to the efficacy of the LNT model may very well be provided by molecular biology.

Dr. Paperiello also expressed an opinion that the public's acceptance of risk is not a constant and varies with their perception of the consequences.

Several examples of public risk acceptance were provided.

Dr. Wymer raised the question as to the time dependency with respect to cost and the need for establishment of an acceptable risk level. Dr. Paperiello replied that he believed the issue of acceptable institutional control is related to the answer, also noting that there are two d1fferent levels of institutional control: one is an ability to intervene and the other, the ability not to intervene, but having the ability to keep people away from the j risk. He also discussed the cost-benefit approach, but stated that a serious l

!- December 16-18,1997 consideration is who pays and who benefits and perhaps, also, who undergoes the risk. It-is his belief that institutional controls will work for a long time and perhaps one should have more confidence in them.

The Committee indicated its intent to sponsor a future working group on the topic as the results of several of the current studies become available. The purpose of such a working group would be to facilitate a technical exchange between several experts in the field, with a particular emphasis on the field of molecular biology.

III. Meetina with the Deoutv Chairman of the Nuclear Reaulatory Commis-sion's Task Force on the External Reaulation of Deoartment of Enerav Facilities (Ocen)

Dr. John Austin. Deputy Chairman. Task Force on the External Regulation of DOE Facilities, stated that DOE has traditionally been a self-regulating govern-ment agency. Starting several years ago a number of studies were commissioned I to explore whether value would be added by external regulation of certain DOE facilities. The NRC has been suggested as the external regulator. A pilot program is underway to measure the added value of external regulation. Some of the expected benefits from external regulation by NRC are the use of an 1 open, public process: greater discipline and accountability; and the increased stability of the process. Three pilot programs are underway. These include a multipurpose license (similar to a university license) at Lawrence Berkeley Laboratory, the radiochemistry hot cells at Oak Ridge National Laboratory, and a spent fuel storage facility at Savannah River. The cost of this year's pilot project for NRC will be about $1 million and involve six employees. In

97th ACNW Meeting 9

December 16-18,1997, FY 1999 five additional projects will be proposed. Decisions on whether or not to have external regulation of DOE will be made in calendar year 1999.

IV. Licensino Requirements for Land Disoosal of Radioactive Waste .

Dr. Andrew Campbell. ACNW staff gave the Committee an overview of the licensing requirements in 10 CFR Part 61 for the disposal of LLW in the near-surface environment. Next Dr. Campblell gave a tutorial. Dr. Campbell discussed the background and applicability of 10 CFR Part 61 described the j structure of the regulation, reviewed its key technical requirenants and performance objectives, and concluded with a discussion of some of the supporting guidance documents for the rule.

In his discussion of the background and development of 10 CFR Part 61. Dr.

Campbell described the available commercial LLW disposal facilities in the 1960s and 1970s, including sites at Barnwell. South Carolina: Beatty, Nevada Virginia: Maxey Flats. Kentucky: Richland. Washington: West Valley New York; and Sheffield. Illinois. He stated that many of these sites experienced  !

problems such as cover stability, mixing of different types of waste, water infiltration, and offsite releases. He noted that the Low-Level Waste Policy Act of 1980 and the Low-Level Waste Policy Amendments Act of 1985 established State responsibility for disposal capacity of commercially generated LLW. The NRC conducted an environmental impact analysis and issued the Draft and Final Environmental Impact Statements for 10 CFR Part 61 in 1980-1981. The final i regulation was promulgated in December 1982.

! 97th ACNW Meeting 10

'l December 16-18,1997 Dr. Campbell described LLW disposal under 10 CFR Part 61. He noted that the regulation applies to all types of LLW disposal technologies for the upper 30 meters of the near-surface environment. He added that shallow land burial (SLB), which was previously used for commercial LLW disposal. is currently banned in many States. Possible disposal system designs under 10 CFR Part 61 l

include above grade vaults (AGVs), with no earthen cover: earth mounded concrete bunkers (EMCBs); and below grade vaults (BGVs). He added that most States and Compacts are developing engineered disposal systems including SLB with an engineered cover at two arid sites and concrete vaults at humid sites (mostly EMCBs and BGVs). All proposed designs will use multilayer covers to keep water from infiltrating into the waste.

He also discussed application of Part 61 to different disposal technologies.

He noted that most parts of the regulation (e.g., licensing, administrative.

and procedural sections; performance objectives: environmental monitoring: and institutional control) apply to all forms of land disposal (for LLW). In contrast. the technical requirements under Subpart D apply only to disposal below the ground surface and do not apply to AGVs or to disposal deeper than 30 meters (e.g., mined cavities). For these other disposal technologies, technical requirements would have to be established on a case-by-case basis.

He described Subpart B requirements for specific technical information, including site characteristics: design features and their relation to the performance objectives: design basis natural events: construction and opera-tions plans: description of exploitable natural resources at the site:

descriptions of the material to be disposed: establishment of quality, safety, and monitoring programs: and administrative procedures to be followed.

b ., *)

97th ACNW Meeting 11 December 16-18,1997 Dr. Campbell said Subpart B also contains requirements in S61.13a. b. c. & d that technical analyses be done to provide " reasonable assurance" that performance objectives will be met. These include performance objectives in S61.41 (protection of general public - dose limits), in S61.42 (protection for the inadvertent intruder). S61.43 (protection of workers and general public during operations), and S61.44 (assuring long-term stability of the site).

Other information requirements concern institutional, financial, special nuclear material (SNM), and criticality issues. The Commission may also impose additional requirements for the license.

Dr. Campbell described the 10 CFR 61.41 performance objective for protection of the general population from releases of radioactivity in Subpart C. He defined LLW performance assessment (PA) as the technical analyses required in 10 CFR 61.13(a) that are used to demonstrate compliance. The analyses must clearly demonstrate " reasonable assurance' that the exposure to humans from the release of radioactivity will not exceed the limits set forth in $61.41.

He also said that LLW PA is cor.cerned with analyses of long-term (post-closure) performance. He noted that the regulation specifies that the pathways analyzed must include air, soil, ground water, surface water, plant uptake, and exhumation by burrowing animals. He also said that the rule requires that the analyses clearly identify and differentiate between roles performed by the natural disposal site characteristics and the design fea-tures.

I Dr. Campbell said that the 10 CFR Part 61.42 performance objective provides j for intruder protection after the end of institutional controls. He said that l the 10 CFR 561.13(b) technical analyses require the applicant to demonstrate

. December 16-18,1997 that the facility will meet the waste classification requirements in S61.55, that the waste segregation requirements in S61.7(b)(2) & $61.55 will be met, and that the facility will provide adequate barriers to inadvertent intrusion l

as per $61.7(b)(3) & (5). He added that separate intruder dose analyses for

$61.42 are generally not done for LLW PA. However, an intruder analysis might be required if an anomalous " waste spectrum" includes sufficiently large quantities of long-lived radionuclides such that the intruder cannot reason-ably be protected by the waste classification and intruder barrier require-ments of 10 CFR Part 61.

Dr. Campbell noted that the S61.43 performance objective for protection of individuals during operations requires that worker doses conform to the 10 CFR Part 20 limits and that offsite doses to the general public conform to the 551.41 dose limits. He briefly discussed the S61.44 performance objectives for long-term stability after closure. He said that stability is addressed separately from PA in the license application, except as it has an impact on meeting the performance objectives in S61.41 Dr. Campbell then discussed the site suitability requirements of S61.50, in Subpart D. These requirements focus on isolation of waste and long-term performance. He said the requirement that the site shall be capable of being characterized and modeled often leads to confusion. He said that the intent was to promote the selection of sites with relatively simple geologic and hydrologic features. Other site suitability requirements include the following: l l

avoiding areas of future development or with exploitable natural re-sources:

requiring the site to be well drained, to be free of flooding or ponding, and to have minimum upstream drainage; and l

1 precluding selection of sites where groundwater intrusion into waste could occur or where surface discharge on the site could occur from the hydrogeologic unit (s) containing waste.  !

)

The rule also specifies avoiding areas where the frequency, rate, or extent of tectonic activity (e.g., seismic and volcanic) or of surface geological  !

processes (e.g.. erosion) may affect the ability to meet the performance objectives or preclude defensible modeling and predictions of long-term impacts.

Dr. Campbell discussed the design requirements in S61.51. This part of the ,

rule specifies that design features be directed to long-term isolation of waste, avoiding maintenance, and requires that design and operations be I compatible with the closure plan and long-term stability: that the design complement natural site features to achieve the performance objectives: that covers be designed to minimize infiltration and resist degradation; that surface features be designed to resist erosion, and that the site be designed 1 to minimize water contact with waste.

Dr. Campbell then discussed the technical requirements for operation and closure in S61.52. He noted that the regulations require that unstabilized i

. December 16-18,1997 Class A waste be segregated from Class B and C wastes, that Class C waste have a minimum cover of 5 meters or be put behind a 500-year intruder barrier, that the package integrity be maintained during disposal, and that void spaces be filled to reduce subsidence. He noted that these requirements are focused on concerns from problems that developed for trench disposal systems. The regulation also limits surface exposure levels to Part 20 iimits, requires that boundaries and locations be known, and that a buffer zone be established that is adequate for monitoring and remediation. He also discussed the requirements for environmental monitoring in $61.53, including pre-operational monitoring, plans for correcting migration, and monitoring conducted during operations and after closure.

Dr. Campbell next discussed the waste classification system in $61.55. He noted that the rule is concerned with both long-lived radionuclides, which are hazardous long past the effectiveness of institutional controls, waste forms, etc., and short-lived isotopes, for which institutional controls and other measures can effectively limit doses. He said that Class A waste must meet the waste characteristic requirements in S61.56 and needs to be segregated from B and C wastes if it is not stabilized. He noted that the concentration limits for Class A waste are such that it will not present an unacceptable hazard to the intruder after the 100-year institutional control period. Dr.

Campbell said that Class B & C wastes also must meet the waste characteristic requirements in S61.56, and must be stabilized (i.e. must be shown to meet the 300-year stability requirement). He noted that Tables 1 and 2 and the illustrative calculations are used to determine waste class.

Ib a - a,

  • 97th ACNW Meeting 15 December 16-18,1997 Dr. Campbell also discussed the land ownership requirements in S61.59. The rule requires land ownership by the State or Federal Government, but has a provision for exemptions (561.6) on a case-by-case basis. He noted that Utah, an Agreement State, granted an exemption to the Envirocare facility. He also discussed institutional control provisions of the rule. These require that the owner or custodial agency control access, fcrbid reliance on active institutional control for more than 100 years post closure, and assume

" passive institutional control" after 100 years.

Dr. Campbell noted the availability of the following guidance documents:

the Technical Position on Site Suitability:

NUREG-0902. Selection and Characterization:

the Technical Position on Waste Classification:

{

. Regulatory Guide 4.19. Site Selection:

NUREG-1199. Standard Format and Content Guide:

97th ACNW Meeting 16

. December 16-18,1997 He discussed some of the pertinent parts of the SRP NUREG-1200. He noted that SRP 56.1 provides general guidance on LLW PA but is not very specific.

It identifies release scenarios and transport pathways; specifies the numeri-cal performance assessment to determine compliance; addresses three fundamen-tal parts of the analysis: release, transfer, and dose; and identifies the ground water pathway as the most important. He noted that the SRP emphasizes

{

site-specific analyses throughout PA. It also states that the purpose of PA is to bound potential impacts for the purpose of making a regulatory decision: j PA is not a prediction of actual impacts. The SRP specifies that the regula-tory authority may impose waste form and packaging requirements and inventory limits. He said that the approaches used in State regulatory reviews are

]

generally consistent with the SRP.

Dr. Campbell discussed the need for additional LLW PA guidance to address aspects of PA not addressed in the SRP. He said that such guidance should explain the overall PA process and establish the relationship between site characterization and design and the PA process. It should discuss using generic data in PA resolving key regulatory issues (e.g., time frame) and  !

using uncertainty and sensitivity analyses. It should explain model confirma-tion (" validation") and code verification. It should describe and provide  !

ways to resolve key technical issues in infiltration, concrete degradation.  ;

source term, and transport of radionuclides.

Dr. Campbell described the Draft Branch Technical Position on a Performance Assessment Methodology for Low-Level Radioactive Waste Disposal Facilities (NUREG-1573, issued for public comment in May 1997). He discussed the goals of the guidance and its relationship to the regulation. He described the

1 97th ACNW Meeting 17 December 16-18,1997 overall performance assessment methodology for LLW developed for the NRC by Sandia National Laboratory and its application via a PA process described in the BTP. He discussed some of the key technical policy issues, including consideration of future site conditions, processes, and events: the perfor-mance of engineered barriers: the time frame for LLW PA: the treatment of sensitivity and uncertainty in LLW PA: and the role of PA during operations and closure. In conclusion, he discussed some specific modeling issues for the subsystem modules in the LLW PA approach.

The Committee members asked a number of questions. One line of questioning concerned the types of long-lived radionuclides going into LLW sites and whether these types were anticipated when 10 CFR Part 61 was developed. Dr.

Campbell said that the amounts of uranium, especially depleted uranium, were not anticipated. For example, he noted that the Draft Environmental Impact Statement for 10 CFR Part 61 considered only about 20 curies total uranium, whereas some LLW sites have more than 2,000 curies of uranium. He noted that the main issue for uranium was the dose potential of the daughter products that grow in over long time frames. He also noted that concentration limits

, for uranium were included in the draft rule, but dropped from the final rule in response to comments and because it was not anticipated that significant uranium would be going to LLW sites. The Committee members also asked about the form of intruder analyses achieved for a 10 CFR Part 61 site. Dr.

Campbell noted that such analyses are not generally done and that compliance with the S61.42 performance objectives is achieved by showing compliance with the waste classification system and the waste segregation and intruder barrier requirements.

[Mr. Richard Major was the Designated Federal Official for this part of the meeting.]

Mr. Richard Major. ACNW staff, summarized a status report on the Yucca Mountain project sent to the Committee by Ms. Carol Hanlon of DOE's Yucca l

Mountain Project Office. Among the t.;ms of interest were the following:

Preparation of the viability assessment (VA) is on target. The VA is

, scheduled for delivery by September 15. 1998. It will consist of five volumes: (1) summary introduction. (2) design. (3) performance assess-l ment. (4) license application plan, and (5) cost estimate.

The waste isolation and containment strategy is in final review before publication. This document will reflect the current view that engineered barriers should be used to compensate for uncertainties in natural

, barriers. The uncertainties may lead to enhanced engineered barriers such as drip shields or ceramic coatings on the waste package.

. The drift scale heater test began on December 3.1997. This test is designed to acquire a more in-depth understanding of the coupled thermal-mechanical-hydrological-chemical processes occurring in the rock mass surrounding the proposed repository. This test will last approximately 10 years.

I VI. Hiah-Level Waste Issue Resolution Status Reoorts and Accentance Criteria (0 pen)

[L, Deering was the Designated Federal Official for this part of the meet-ing.]

Mr. King Stablein, Acting Chief. Engineering and Geosciences Branch, NMSS, briefed the Committee on the progress made to date and expected in 1998 in the high-level waste (HLW) issue resolution process. Mr. Stablein discussed the purpose and context of Issue Resolution Status Reports (IRSRs), the structure and content of the IRSRs, the IRSRs issued to date or to be issued in FY 1998, and progress toward issue resolution documented in IRSRs already issued.

Mr. Stablein discussed the following recently issued IRSRs: Unsaturated.and Saturated Flow Under Isothermal Conditions. Thermal Effects on Flow, Evolution of the Near-Field Environment, Structural Deformation and Seismicity, and Repository Design and Thermal-Mechanical Effects. For each IRSR, Mr. Stablein described the issue and associated subissues, summarized progress toward

addressed.  ;

Issue resolution. Mr. Stablein said. is focused on the 10 most important 1

issues to repository performance (key technical issues. or KTIs) providing. I early feedback to DOE on issues (avoiding surprises) and demonstrating measurable progress. The IRSRs are used to document the status of NRC's position on various issues.

)

Issue resolution is achieved when the staff has no more questions on an issue or subissue, and, as such, occurs at the staff level only. IRSRs are based on information gained through NRC-D0E technical exchanges, less formal Appendix 7 meetings, and written correspondences.

Each IRSR contains an introduction, a description of the issue or subissue, the importance of issue to repository performance, acceptance criteria review methods and technical bases, status of progress toward resolution, and references.

The staff is currently using the Total System Performance Assessment-3 code to conduct sensitivity analyses and is in the early stages of documenting the results. The results of sensitivity analyses will be used to reevaluate the importance to performance of the subissues within KTIs and of the KTIs l themselves. The ACNW encouraged the staff to be flexible in selecting KTIs  !

and subissues in response to new information from the sensitivity analyses, and suggested that the staff may be surprised by some of the results, given i

I l

l

o, 97th ACNW Meeting 21 l

,' December 16-18,1997 I that the existing KTIs and subissues were only based in part on the results of PA.

The acceptance criteria for each IRSR are aimed at methods for testing, modeling, and PA. The staff is now working toward making the acceptance criteria consistent with one another.

IRSRs are developed by a team from the NRC and the Center for Nuclear Waste Regulatory Analyses staffs. The ACNW asked how the staff plans to manage complex. multidisciplinary issues, such as coupled processes and other issues that are closely linked. in the IRSRs. Dr. Brett Leslie. NMSS, described how sensitivity analyses are being conducted on each issue or subissue within a KTI. such as coupled effects in the evolution of the near-field environment.

The results are abstracted and passed along as input to the container life and sourc'e term KTI. Dr. Leslie indicated that the impacts of man-made materials on the near-field chemical environment will not be handled until Rev. 2 of the IRSR on Evolution of the Near Field. It was also noted that mechanical coupled effects will be considered in a separate IRSR under the KTI on Repository Design. Mr. Stablein noted that the KTI teams stay in continual contact with one another to integrate the information. The ACNW noted that using PA to evaluate the KTIs and subissues may lead to a totally different structure for characterizing the issues and information.

i The staff plans to conduct sensitivity analyses at the process and total system level in FY 1998. Mr. Tim McCartin, NMSS, said that it is difficult to know what specific information and coupling of information at the process level must be included in the PA. The staff is in the process of determining )

97th ACNW Meeting 22 December 16-18,1997 this. He noted that it must be done in an iterative fashion starting with the results of early sensitivity analyses, then evaluating the importance of various coupled effects.

The ACNW was impressed with the staff's IRSR activities, but expressed concerned about how the staff will comprehensively evaluate complex issues, such as coupled effects, and write IRSRs before the fall of 1998, when the Viability Assessment (VA) is scheduled for delivery.

(

DOE is expected to respond to the five IRSRs rec.atly issued by early 1998.

Although DOE's initial verbal response to some of the IRSRs has been favor-able, NRC anticipates that DOE will not respond favorably on some of the more contentious issues.

The staff believes that significant progress toward issue resolution has been made on issues most significant to performance. The staff expects that progress on issue resolution should facilitate the staff's review of the VA and limit the likelihood of NRC's identifying unanticipated problems in the VA.

The ACNW plans to begin working on a report on this subject at its next meeting.
