- 1. CHAIRMAN'S REPORT (0 pen)
[Mr. R. F. Fraley was the Designated Federal Official for this portion of the meeting.)
Dr. Moeller introduced the Committee and its consultants and noted the attendance of Dr. Paul Shewmon of the Advisory Committee on Reactor Safe-guards (ACRS).
Dr. Moeller announced the receipt of a letter of appreciation from Chairman Zech and thanked his fellow members, ACNW supporting staff and consultants for their part in these accomplishments.
He requested that the members note their availability on a 1990 calendar.
With reference to obtaining a scoping probabilistic risk assessment study on the Yucca Mountain site Dr. Moeller indicated that the Office of Nuclear Regulatory Research (PES) has such a study under development, which will be the topic of a briefing in the near term.
The presentation schedule on the Site Characterization Analysis was detailed and the members and consultants were reminded that the material that had been distributed was predecisional and should not be disseminated beyond the Committee.

10TH ACNW MINUTES MAY 11, 1989
- 11. SITE CHARACTERIZATION ANALYSIS (SCA) (0 pen)
[ Note: Dr. S. J. S. Parry was the Designated Federal Official for this portion of the meeting.] {
Dr. King Stablein, NMSS, is the project manager for the preparation of the SCA. Dr. Stablein stated that the briefing will be subdivided into six general areas of technical concerns. Each area will have a principal pre-senter. The SCA is in an early stage of development and at least two addi- ;
tional versions will be submitted to the Committee.
Dr. Sti.blein described the process for preparing the SCA and identified the current draft as the " branch" draft meaning that the comments had only received a management review at the branch chief level. He noted that the individual groups of comments would be integrated to avoid duplication in the future. It was also stated that the presentations would not be a page-by-page review of all the comments, but would focus on items of particular interest. In response to questions from Dr. Moeller and some consultants, Dr. Stablein discussed portions of the Site Characterization Plan (SCP) and procedures to resolve some of the staff's earlier questions and concerns.
A. Quality Assurance (QA)
Mr. James Conway, NMSS, identified two principal concerns of the staff with the QA aspects of the SCP. They were: (1) implemen-tation of the QA program, in toto, and (2) certification of data collected before the QA program was placed into effect. Drs. Smith, Steindler, and Hinze raised questions with Mr. Conway. Dr. Smith was concerned that the NRC staff was not aware of DOE's plans to certify pre-existing data. Dr. Steindler noted that merely provid- i ing an adequate paper trail was not sufficient to ensure competent 1 data. He stressed the need to demonstrate the quality or technical soundness of the data. Dr. Hinze questioned the adequacy of the data used to site and design the exploratory shaft. The staff responded in general terms to these questions.
In closing, Mr. Conway commented on the incompleteness or limited content of the Q list as presented in the SCP.
B. Geology / Geophysics Ms. Charlotte Abrams, NMSS, commented that she planned to present selected topics of concern in the SCP. Upon questioning by Drs.
Hinze and Parry, Ms. Abrams indicated that these topics were select-ed because they were either the most interesting or of greatest concern. Ms. Abrams noted that there are central themes that run through the various topics, and that these themes are interrelated.
These central themes were stressed during the presentation.
Ms. Abrams addressed the question of tectonics and fault movement.
She noted that the location of the exploratory shaf ts may not comply
. s i
1 10TH ACNW MINUTES MAY 11, 1989 with-limitations proposed in referenced reports, and that the staff plans to review the matter in detail. Dr. Hinze questioned whether i the relocation of the shaft had' taken into account factors other-l ,
than' the surface exit of the shaft. Ms. Abrams stated that a f considerable effort had been expended in considering the relocation l of the shaft but that the staff was still concerned that the charac-terization area was not representative'of the entire block in which- ;
the repository is to be located.
The staff discussed their concerns relative to faulting. It was noted that the SCP did not fully integrate or consider alternative 1 conceptual models of .. faulting. Further, the possible effects of ]
nearby faults were not included. Faults were treated ~ as narrow 1 discontinuities rather than planes of movement having finite di-mensions. Ms. Abrams also pointed out that the SCP did not clearly take into account the postclosure tectonics or various waste package and performance issues. Upon questioning by Dr. Hinze, she stated that the fault slip rates have not been determined in sufficient detail. Ms. Abrams observed that a detailed review of the geologic data has not been performed since 1984.
Ms. Abrams restated that DOE does not appear to have taken into sufficient account the possible effects of fault movement on the postclosure vative. Two performance and that examples of this are:the(1desig)ns appear to be nonconser-the characterization of faults being limited to those with movement greater than one meter in the quaternary and 100 meters in tertiary rocks and (2) the assumption that new faulting will follow existing faults.
Dr. Shewmon raised a question as to whether models to predict faulting exist. The staff said that there were tabulations of such models and agreed to provide them to the Committee. Dr. Hinze asked if all the faults in the site had been located. The staff said that additional faulting was possible, particularly, since all current fault detection studies have been based on surface studies. Dr.
Hinze suggested two investigatory procedures that could be used for developing further detail on the location of faults.
Ms. Abrams stated that DOE had considered alternative conceptual models relative to volcanism. Sufficient consideration has not been given to nearby volcanic structures, such as the Death Valley Pancake Range Volcanic Belt. Also, limiting the area of considera-tion to 70 km appears to be questionable. Dr. John Trapp, NMSS, noted that the rate of volcanic events expected or projected by DOE is not consistent with the staff's projection.
There was a discussion between Drs. Trapp, Moeller, Steindler, Moody and Parry concerning performance allocation and the setting of
" goals" for the values of physical parameters. Dr. Trapp noted that the " goals" or acceptable limits set by DOE on the parameter of
w .
t 10TH ACNW MINUTES MAY 11, 1989 volcanic activity would not allow the _ site to meet the EPA perfor-mance criteria. Ms. Abrams noted a lack of integration between the volcanic and tectonic studies. She noted that this problem was apparent during a recent field trip by the NRC staff to the site and surrounding araa. Dr. Hinze commented that there appeared to be -
limited substance and/or comment on this matter in the SCP. Ms.
Abrams concurred and indicated that the staff was awaiting the study plans to firm up the substance of the program. The lack of, or .
delay in,-receiving the study plans was discussed.
Dr. Smith raised the question of how the site suitability decision is to be made. No clear concerns or statement defining the deci-sion-making process was forthcoming from the staff. Dr. Trapp stated that progress was being made by DOE. Dr. Orth noted that as some concerns were resolved, new concerns arose. He wondered if the number of concerns was increasing or decreasing.
Ms. Abrams moved to the topic of seismicity. Dr. Steindler asked if the values now proposed by DOE were more conservative than previous-ly presented.- Ms. Abrams stated that some concerns had been resolved, but that the numbers had not changed drastically. Mr.
McConnell noted that DOE has become more conservative in the area of alternative models.
There was a further general discussion on the prediction of seismic events and their consequences. Dr. Foster asked if there was an effort to determine a nonacceptability limit on the site. Dr. Smith supported this question but no clear response was given. The inference was that it is DOE's responsibility to make a negative determination on the site's suitability.
Ms. Abrams discussed natural resources and stated that the consid-eration of alternative models in this area was limited. Further, the integration of studies related to natural resources was limited.
Dr. Smith questioned what constituted a natural resource in terms of economic value. Ms. Abrams said that a natural resource was not defined in dollars, and that no studies were proposed to explore possible ore sites, such as faults. Only vertical drilling was proposed. Dr. Hinze commented that the potential for natural resources can be flagged by adequate exploratory studies and recom-mended that such studies should be done.
The lack of coordination in the geophysical studies was discussed by Ms. Abrams. She noted that no program was directed toward the identification of volcanic igneous features, for example. Dr.
Steindler asked if this was because it was early in the program.
Ms. Abrams said no; no programs had been proposed. Dr. Hinze commented on the lack of proper sequencing of tests. The lack of homogenity in the rock was noted at length, as was the capacity of the site.
10TH ACNW MINUTES MAY 11, 1989 The adequacy of the surface-based testing programs was discussed.
Mr. Abrams stated that additional testing both in terms of quantity and technical complexity, would be desirable.
C. Hydrology and Geochemistry Mr. Jeffrey Pohle, NMSS, led the presentation on hydrology. He indicated that there were several concerns related to the determina-tion of the groundwater travel times (GWTT) and the definition of the disturbed zone. DOE proposed a disturbed zone boundary based upon changes in the permeability and porosity. While the NRC staff did not disagree with the approach, they questioned limiting it to two properties.
There was a discussion between Mr. Pohle and Drs. Moeller and Parry on the state of the geologic structure when the GWTT is measured.
Mr. Pohle indicated that empl6 cement activities would affect the GWTT. Drs. Moeller and Parry expressed the opinion that the GWTT was to be measured in an undisturbed structure. [ Note: Review of the regulation, Section 60.113, shows that the GWTT is to be a prewaste emplacement value. This seems to refute the staff's stated position.]
Mr. Pohle then discussed the use of GWTT in constructing the cumula-tive distribution curves. The staff believes that 00E is using an inappropriate procedure of tending to consider values near the mean, rather than allowing for the effect of limiting values. Dr. Steind-ler questioned the staff's concerns in this area.
Mr. Pohle detailed the limitations of DOE's gechydrology program.
Basically, the staff found no improvement or expansit i in DOE's proposal from that put forward in the Consultation Draf t SCP. He noted that there were no plans to characterize the Calico Hills structure that underlies the repository site and is the site's primary barrier. Dr. Moeller questioned this point since previously the staff had objected to DOE's penetrating that lower structure.
Dr. Moody asked if the regional flow system studies proposed are adequate and if test site data are available. It was suggested that l the regional studies are adequate, but not all of the test site data I has been made available.
Dr. Shewmon questioned the status of the waste packages with respect l to exposure to water. Mr. Pohle stated that the current approach is 1 to assume a steady-state exposure to moisture of limited volume, and mostly likely as a vapor.
l Dr. Hinze asked what F.ow regime has been assumed, fracture or I porous media flow. Mr. Pohle stated that DOE is stressing porous media flow although the evidence suggests that fracture flow is the 1
.10TH ACNW MINUTES MAY 11, 1989 most likely process. He further indicated that DOE is attempting to mathematically represent fracture flow as porous flow.
Dr. Smith raised questions related to the determination of site suitability and the closure of technical issues. Mr. Linehan stated the staff's concerns have been voiced to DOE but not prioritized as yet. He stated that the SCA would include a prioritization of concerns.
Mr. Pohle discussed the geochemical concerns. He noted that no plans were presented for investigating the concentration of radio-nuclides on the surfaces of fractures. Mr. John Bradbury, NMSS, confirmed that statement in detail. There was an expanded discus-sion of this point by Drs. Steindler, Moody, and Mr. Voiland. The DOE assumptions as to the value of the effective Kds were reviewed.
The nonconservative effect on the calculated performance of the repository was noted.
Drs. Steindler, Cherry and Mr. Pohle discussed performance assess-ment and the uncertainty resulting from using data of limited range.
D. Materials Engineering The staff's review of those portions of the SCP that relate to waste package materials was presented by Dr. Kien Chang, NMSS. He noted that DOE had altered their concept of substantially complete containment in the SCP, from that in the CDSCP. He noted some of the " goals" set for repository conditions. The details of the waste package emplacement system apparently were not included in the SCP.
Dr. Shewmon questioned the logic of some of the " goals" that were defined. Dr. Steindler also questioned some of DOE's positions.
Dr. Chang noted that the staff's earlier question on the CDSCP relative to standardized testing procedures was not addressed in the SCP. Mr. Voiland asked if there were study plans in preparation that might address this question. The question was not answered directly but it was stated that study plans were in preparation.
Their content was either not known or not presented.
The behavior of carbon-14 was questioned by Dr. Moeller. Dr. Chang stated that alternative designs to handle it were proposed by DOE.
DOE has also raised the possibility of obtaining a regulatory exception for carbon-14 releases. ,
Drs. Steindler and Shewmon questioned Dr. Chang on the staff's desire for standardized tests whose results may be extrapolated with confidence.
10TH ACNW MINUTES MAY 11, 1989 E. Performance Assessment Mr. Norman Eisenberg, HMSS, was the principal presenter in the area of performance Assessment. He stressed the continued lack of an integrated or coordinated approach to performance assessment, which was also observed in the CDSCP. He enumerated six specific areas of concern. They were: performance allocation, alternative conceptual models, the use of performance.essessment to guide site characteri-zation, validation of scenario analysis, and the formal use of expert judgment. 1 Dr. Steindler questioned if the staff was objecting to the system not yet being operative. Mr. Eisenberg said no. He stated that what was in place and presented was incomplete and in some cases either inadequate or illogical. As an example, he cited the canis-ter failure rates proposed over 1000 years, wHch neglected to specify the cumulative number of canisters thai. would have been expected to have failed. Additional examples were drawn from the hypothesis testing tables where there appeared to be inconsistencies from discipline to discipline. He noted that the first total system performance assessment is not scheduled to be completed until 1993.
Mr. Eisenberg stated that the staff was not satisfied with the validation program proposed by DOE. However, upon questioning, he was unable to define clearly an approach acceptable to the staff.
He stated that a technical position on this question was being con-sidered. The inability of the staff to annunciate its requirement in this area was addressed by several members and consultants. Mr.
Ballard stated that this topic had been proposed to the Commission in SECY-88-285, " Regulatory Strategy and Schedules for the High-Level Waste Repository Program," October 5,1988.
The concern with scenario analysis was discussed. One point that was made was that scenario analysis was often cor. fused with alterna-tive conceptual models. Mr. referenced a report by Mr.
Eisenberg[ Note: A copy of the report Benjamin Ross to clarify the concern.
entitled, "A First Survey of Disruption Scenarios for a High-Level Repository at Yucca Mountain, Nevada," SAND 85-7117, December 1987, has been forwarded to the members and consultants.]
In closing Mr. Eisenberg reviewed the DOE's approach on the use of expert judgment. He gave an example of what the staff believes is inappropriate use of such input and noted the staff's intention to prepare a technical position on the matter. Mr. Eisenberg comented that he personally disliked having to use expert judgment. He believes that by appropriate planning one should be able to minimize or avoid the use of expert judgment. Dr. Moody noted that in the earth sciences it is impossible to avoid using expert opini3ns.

F. Geotechnical Engineering l The final presentation, which covered geotechnical engineering, was 1 given by Dr. Dinesh Gupta, NMSS. He described the three geotechni-cal objections made in response to the CDSCP. They were: (1) location of the exploratory . shaft, (2) depth of the exploratory shaft, and (3) interference among tests. Of these the first appears l to have been fully resolved, the second partially so, and the third '
has been approached constructively by DOE in the SCP.
He noted that the expansion of the SCP over the CDSCP had given rise to four new concerns. These are not yet characterized as objec-tions. The are: (1) acceptability of the exploratory shaft design, (2) yadequacy of the testing program, (3) integration of the designs of the repository exploratory shafts and test facilities, and (4) details of the performance confirmation program.
The acceptability of the shafts' design has been addressed by the Design Acceptability Analysis (DAA). The staff has -found that certain contributors to the DAA were also involved in the design project itself. Thus it appears that there is a potential for a conflict of interest. DOE also failed to address all the applicable design requirements in the DAA, and some that were addressed were inadequately covered. He gave several examples.
Drs. Smith, Hinze, and Pomeroy questioned Dr. Gupta on the staff's definition of conservative data. A definitive answer was not provided.
Dr. Gupta detailed the staff's concerns about test interferences.
DOE's improved approach was noted but the staff believes that l interferences will occur and that sufficient time and/or space has not been allowed for the program. He particularly noted the lack of tests of full-scale packages, that contain radioactive materials.
, With respect to the site characterization program itself, Dr. Gupta l noted the limited number of boreholes to be drilled. He also l pointed out that these were generally drilled vertically, whereas the staff would prefer some to be drilled at an angle to transect vertical geologic features, such as faults. The proposed dry drilling procedure with continuous core removal, was discussed. It is an unproven technology, but desirable, if feasible. Questions were raised about the desirability of drilling numerous holes into the repository horizon.
The spatial requirement for the repository and the test area were discussed. The staff's calculations do not support the DOE's claims as to available space. A representative from DOE-Las Vegas indicat-ed that the difference was related to layout of the repository and siting of the canisters themselves.
1 I
l l
I 10TH ACNW MINUTES MAY 11, 1989 In closing, Dr. Gupta noted the staff's opinion that the SCP does not address the question of retrievability or the performance 4 confirmation program in sufficient depth. l Ill. DRAFT FINAL TECHNICAL POSITION ON ENVIRONMENTAL MONITORING
[ Note: Mr. O. 5. Merrill was the Designated Federal Official for this portion of the meeting.]
Mr. John Surmeier, Division of Low-Level Waste Management and Decommission-ing, gave the introductory remarks. He stated that this final version of the Environmental Monitoring Branch Technical Position (BTP) provides general policy guidance, as recommended earlier by the Committee, rather than de-tailed technical guidance. He then introduced Dr. Edward Shum, a senior environmental chemist in the Siting Section of the Technical Branch, who gave the presentation.
Dr. Shum provided some background on the development of the BTP, stating that about 14 organizations and agencies provided comments on the draft BTP that was published in the Federal Register on November 5, 1987. On July 22, 1988, they briefed the ACNW on this subject and reviewed the comments made by the Committee in its August 9, 1988 report to Chairman Zech via the transcript of that meeting. A summary of the major comments received from all commentors on the draft BTP follows:
- 1. The intent of the BTP should be clearly stated.
- 2. The BTP should provide more specific guidance, i.e., be more pre-scriptive.
- 3. The objectives of monitoring are unclear.
- 4. The one-year period of preoperational monitoring should be extended.
- 5. The critical pathways should be considered.
Dr. Carter raised a question about the definitions in the BTP of the monitor-ing periods -- preoperational monitoring, monitoring during operation, and postoperational monitoring, which he said appea" to be internally inconsis-tent and in need of a little polishing. Dr. Shum said they were using the definitions given in Part 61.2 where monitoring is defined as " observing and making measurement to provide data to evaluate the performance and character-istics of the disposal site." Hence, he believes that there is no choice but to use this definition, although they would prefer otherwise.
Dr. Shewmon asked if the definitions are not relevant to a low-level disposal site, will licensees still be bound by them? Mr. Surmeier explained that the definitions were developed for the siting of a nuclear power plant whereas they are currently talking about a geologic setting for a disposal site.
10TH ACNW MINUTES MAY 11, 1989 This is why they believe there is a need for a guidance document on this matter.
Dr. Carter said that he would agree that the document should not be prescrip-tive (referring to page 9 of the BTP), but said that the issue is compounded by reference to Appendix A which is extremely prescriptive. Dr. Shum ex-plained that Appendix A was included as an example in response to the com-mentors who recommended more specific guidance. Mr. Surmeier added that the s+aff would be willing to remove this appendix from the document. Dr. Shum agreed but said that an applicant, the licensee, would like to have it remain. Dr. Carter suggested that the appendix be removed, that a few of the words within it be modified, and that it be cited as a reference.
Dr. Carter observed that the staff had not sufficiently addressed the need for environmental modeling; most of the performance assessment will be done with modeling. Dr. Shum agreed and explained the complexities of the problem ,
of the pathway analysis and source terms. He said that the staff tried not 1 to get into pathway analysis because it depends on a standard, such as the EPA Clean Air Act. They would rather use a conservative approach.
Dr. Carter commented that most of the monitoring measurements will be of very low values so the use of modeling will be necessary. Dr. Shum agreed that the measurement of very small values would be extremely difficult. Dr.
Carter said that, for the record, Dr. Shum was talking about the low values proposed by EPA under the proposed revisions in the Clean Air Act.
Dr. Steindler asked what would happen if this document were not issued. Dr.
Shum said that the state authority or organization that is not a specialist in this area may need this type of overall guidance to ensure that they are aware of the types of things they must take into consideration in their monitoring program. Dr. Smith confirmed that it would be to the advantage of the licensee to have the guidance in one document rather than scattered throughout several references.
Dr. Moeller cited three references that he has used in this regard over many years, viz. ,
- 2. DOE's guide for Environmental Radiological Surveillance at U.S.
Department of Energy Installations, DOE /EP-0023, Revised July 1981
- 3. The Use of Reconnaissance Level Information for Environmental Assessment,NUREG/CR-0990(PNL-3080), December 1979 Dr. Shum agreed that these are very good reports. He cited a recent 1989 DOE report that is a consolidation of earlier reports.
I I
l
\
i 10TH ACNW MINUTES MAY 11, 1989 Dr. Foster agreed with the previous comments about Appendix A to the extent that it is too prescriptive and should be deleted. He said that if it was not, the applicant would probably pattern his aoproach after it rather than being site specific.
Mr. Voiland said that the results of monitoring the performance of existing l L facilities such as the Beatty, Barnwell and Richland sites are probably "a i bunch of zeros," with which Dr. Shum agreed. Mr. Voiland added that there is again the matter of becoming more conservative -- larger zones or length of containment times, for example, both of which seem to be unnecessary for this type of operation.
Dr. Carter wet chemistrysugg(ested e.g., liquid that the staf f takeand carbon-14 a closer look atas iodine-129) thehe requirement questionedforif these are needed. He added that, instead, the staff might want to do screer-ing with things like tritium and gamma sources. He said that the people who use this guidance would have a heavy responsibility on them to do a consider-able amount of wet chemistry and that the question is whether it is needed.
Dr. Shum emphasized that all the staff wants is for the applicant to demon-strate compliance, not to do an isotopic analysis.
Dr. Orth suggested that, in the objectives sections in the front of the document, it would be worthwhile to emphasize exactly why some of the preop-erational testing is to be done.
Dr. Moeller suggested that the text be revised. He invited the staff to meet with the Committee in a couple of months for further review. Marked up copies of the BTP were provided to the staff for possible guidance and help.
IV. EXECUTIVESESSION(0 pen)
A. Site Visits The Committee deferred its planned visit to the Center for Nuclear Waste Regulatory Analyses (CNWRA), San Antonio, Texas. The Commit-tee agreed to review the programs of CNWRA in the near future.
The Committee reconfirmed its intention to visit the West Valley ;
Demonstration Project in October 1989.
B. Future Meeting Schedules Dr. Moeller requested that ACNW Members reaffirm t'eir availability to attend future meetings scheduled during the last three months of 1989 and to indicate their date preferences for meetings to be held during calendar year 1990.
