2.0 INITIAL DISCUSSIONS - APRIL 14, 1986
FINAL ENVIRONMENTAL ASSESSMENTS
After introducing the attendees, Mr. Pohle briefly reviewed the status of NRC
plans to review the Final Environmental Assessments (FEA's). As of that date,
the best guess for delivery of the FEA's was April 28, 1986. The general NRC
plan is to review the manner in which each FEA responds to major and important
specific NRC comments. The intention is to raise new issues or concerns only
if new information presented in the FEA requires the staff to do so. The NRC
anticipates that each of the NWC Site Teams will informally review the FEA,
but Mr. Pohle anticipates little or no involvement by NWC in the formal NRC
review process.
BACKGROUND ON PROJECTS
Mr. Pohle pointed out that there are new references that will be cited in the
FEA's, but that the ability of the staff and contractors to review the FEA in
terms of the information and analyses contained in those references may be
severely limited by the time available to review the primary documents before
reviewing the FEA's. Examples of the new documents include the Groundwater
Travel Time papers currently under review by Daniel B. Stephens and
Associates, the NWC Salt Site Team.
Dr. Williams expressed a general concern about the "stochastic" models now
apparently being used by all the DOE sites to assess groundwater travel time.

TRIP REPORT - 4/14-16/86 -4- APRIL 25. 1986TRIP REPORT - 4/14-16/86 -4- APRIL 25. 1986
There was a brief discussion about technical concerns with this approach,
including issues involving the current version of the NRC's draft GTP on
Groundwater Travel Time. While agreeing that there may be concerns with
specific applications of approaches, Adrian Brown (NWC) recommended that the
Staff take great care in responding to the DOE documents in order to avoid
confusion about the NRC Staff's position on the need to address uncertainty,
which would appear to be the reason that DOE has gone to this technology.
PLANNING FOR SITE CHARACTERIZATION PLANS
Mr. Pohle presented and discussed aspects of a memorandum that he had prepared
for M.H. Fliegel, Hydrology Section Leader, concerning preparing for SCP
reviews (Program Plan for HLW Hydrogeology Efforts in FY86 and FY87 Directed
Toward Preparing for Site Characterization Plan Reviews, Memorandum from J.A.
Pohle to M.H. Fliegel, dated March 24, 1986). A copy of the memorandum is
included in Attachment 2. In addition, Mr. Pohle placed this hydrology
planning effort in the larger context of the Five-Year Work Plan initiative,
which he invited Seth Coplan (WMRP) and Mr. Fliegel to discuss. The
memorandum identifies five objectives of the hydrology planning exercise:
1. Identification of key conditions, assumptions or interpretations in
conceptual models.
2. Identification of types of information necessary to verify the
conditions, assumptions and interpretations of Step 1.
3. Identification of information gaps.

4. Development of WMGT "Branch Perspectives" on technical considerations
for site characterization.
5. Development of staff positions on acceptable testing strategies.
The memorandum also identifies a series of products associated with the
program objectives and discusses the roles of NRC Staff and contractor
contributions to these products. One of the products envisaged is a series of
reports, termed Data Needs Assessments, that present the results of efforts
related to the review and analysis of existing data, conceptual models
evaluations and numerical/analytical analyses. The memorandum indicates that
NWC will have the contractor lead in the development and preparation of these
reports, which will be directed primarily at Items 1-3 above.

3.0 DATA NEEDS ASSESSMENTS
BACKGROUND
Adrian Brown (NWC) began the presentation on the proposed NWC approach to
conducting the Data Needs Assessments with some introductory material about
our understanding of the problem, particularly with reference to preparing the
Staff to adequately review and comment on the DOE Site Characterization Plans.
Major points of the NWC position as expressed by Mr. Brown include:
1. The NRC mandate is to -evaluate, using materials presented In a
license application, whether a proposed HLW repository will meet the
requirements of 10 CFR Part 60, including the overall EPA Standards
(10 CFR 60.112), and, if it does, to issue a license for the
operation of the facility.
2. The NRC is operating under a number of constraints which are
significant with respect to how it fulfills its mandate, including:
a. NRC will occupy the minimum amount of time on the critical path
to licensing that is consistent with protection of the public
health and safety.
b. NRC will do its utmost to avoid rejecting a license application
on the grounds of incompleteness.

TRIP REPORT - 4/14-16/86 -7- APRIL 25. 1986TRIP REPORT - 4/14-16/86 -7- APRIL 25. 1986
c. In general, the NRC will not directly obtain field information,
except to the extent that it may be required for quality
assurance.
3. The effect of these constraints is that the NRC must have access to
information in a timely fashion. Equally important, the NRC must be
involved in the decision-making for testing at each site to ensure
that the information which is being collected includes the minimum
information that the NRC must have to reach a decision on compliance
with the licensing requirements.
4. The immediate focus of the Staff's hydrology assessments ought to be
the development of a set of evaluations that will allow the Staff to
perform an adequate review of the DOE SCP's, since these program
documents will control the collection of data that will be used by
DOE to support a license application.
With respect to reviews conducted by the NRC Staff and contractors, a specific
piece of earth science or engineering information - which may be a datum or an
analysis of data - can be considered needed if and only if one can demonstrate
that it is necessary for an evaluation that is defined in Part 60, including,
ultimately, an evaluation of the the EPA Standards that are incorporated into
the NRC Rule. Since 10 CFR Part 60 and 40 CFR Part 191 are performance
standards, this logic requires that information needs must be defined within
the framework of performance assessments: if a piece of information is not
needed to assess some aspect of performance of a geologic repository, it

cannot be considered an information need within the meaning of the NRC's
ultimate responsibility.
Investigation needs, the principal topic of the SCP process, are a subset of
information needs, since some information may be (and probably is) already
available at each of the sites. To define an investigation need, one must
first identify and document the significance of an information need, then
review the existing information to determine that the data or analysis does
not already exist, and finally demonstrate that it is feasible to develop the
required information through additional investigations.
PROTOCOL FOR HYDROLOGIC INVESTIGATION NEEDS
NWC has developed a general protocol for hydrologic investigations needs that
we consider can be applied to the task proposed by the NRC Staff:
1. Identify the performance objectives of 10 CFR Part 60 and 40 CFR Part
191 that are relevant to hydrology.
2. Define criteria (for success and/or failure) for assessing the system
or subsystem, based on the performance objectives in the rule.
Criteria may include levels of uncertainty which are considered
sufficient to bound performance reliably.
3. Identify the aspects of the hydrology of a geologic repository which
can affect the relevant behavior (i.e., performance).

TRIP REPORT - 4/14-16/86 Beg_ APRIL 25. 1986
4. Develop a model (that is an analog) of the geologic repository or of
a subsystem of the repository which can be analyzed with respect to
performance. The development of the model includes the
identification of the parameters, boundary conditions and stimuli
that must be included to evaluate the model.
5. Review the data that have been collected and select the data that are
believed to be sufficiently reliable to apply in assessments of
performance using the model(s) developed in step 4. If there are
parameters needed for a model for which no -or no reliable- data
exist, then develop a set of bounding data that can be used to define
the sensitivity of the performance of the model to parametric
uncertainty. Alternatively, reformulate the model to solve for (or
find limits for) the unknown datum.
6. Analyze the performance of the modeled system or subsystem against
the criteria established in step 2, using the available data selected
in step 5.
7. If the analysis shows that the available data meet the established
criteria (that is, the modeled system clearly succeeds or clearly
fails), then there is no information need, and consequently no
investigation need.
8. If the the analysis shows that the available data do not meet the
established criteria (that is, the modeled system cannot be shown to

clearly succeed or clearly fail), then one must determine whether it
is feasible to obtain the information (either data or a new data
analysis) that would allow a determination to be made against the
criteria.
9. If the information cannot be feasibly obtained, there is no
investigation need, since no investigation would yield the required
information.
10. If the information can be feasibly obtained, then an investigation
need has been established, and it is appropriate to proceed to
evaluating the plans that are proposed.
11. When new information has been developed as a result of investigations
based on plans developed subsequent to step 10, the performance
assessment is reiterated from step 4 or step 6, as appropriate. The
iterative process ends when the information meets the criteria of
each analysis of performance that is required to establish that the
geologic repository will meet the performance objectives of 10 CFR
Part 60, including the EPA Standards of 40 CFR Part 191.
EXAMPLE: RESATURATION OF A SALT REPOSITORY BY VERTICAL DARCY FLOW
Mr. Brown presented a sample data needs analysis as an example of the way such
mini-performance assessments can be conducted. The example was the analysis
of the information needed to assess the rate of resaturation of a model
repository in bedded salt due to vertical darcy flow of water. The text for

this example, which was also included in the NWC Trip Report of February 13,
1986 (NWC Communication No. 25), is included in Attachment 2.
Discussion of the example centered on how one would go about selecting
specific problems for analysis and some of the key assumptions which were used
in formulating the conceptual model that was used. NWC's response to the
question of topic selection was that we would propose topics, along with a
rationale for their significance, for review by the Staff and other
contractors. The issue of defensible conceptual models was discussed in terms
of performing bounding calculations and the consideration of alternative
conceptual models. At the conclusion of the discussion, NWC committed to
preparing a first cut at a list of proposed topics for each site to be
presented to the group for further discussion on April 15.

4.0 WILLIAMS AND ASSOCIATES' EVALUATION OF NHWSI CONCEPTUAL MODELS
Dr. James Oslensky presented a discussion of major points that Williams and
Associates considered in their report on evaluations of conceptual models for
NNWSI. The W & A presentation addressed concepts of regional, intermediate
and local flow in the saturated zone, and selected areas of technical concern
about mechanisms of flow in the unsaturated zone. Dr. Osiensky showed a short
film on capillary barriers in partially saturated, porous sands.

5.0 TOPICS FOR DATA NEEDS ANALYSES - APRIL 15. 1986
Mark Logsdon (NWC) began the presentations with a brief introduction on
limitations and assumptions. Key points in his introductions included:
1. The topics that were to be presented all began with consideration of
technical "open items" (ne "issues"), but are posed as questions that
are related to performance of a geologic repository with respect to
the EPA Standard for long-term isolation.
2. The topics of the morning's presentations were an initial set of
questions only. Our experience has been that new questions are
generated as work progresses on these topics.
3. The presentations would be at a "rough cut" level, intended to show
the level of fundamental questions that need to be addressed. The
hope was that there would develop a consensus that the approach and
the initial topics were appropriate for NRC analysis. NWC and its
subcontractors have ideas on how to approach the fundamental
questions, but details remain to be worked out.
Lyle Davis (Water, Waste and Land) began by presenting a series of questions
related to NNWSI. The approach and the basic questions are summarized on
Figure 1, which was presented at the meeting.
Dan Stephens (Daniel B. Stephens and Associates) presented an analogous series
of questions, which build on the performance assessment work that has already

been done for salt by SNL, DOE, WIPP and Golder Associates (GAl). The
approach and specific questions are summarized on Figure 2.
The BWIP presentations were deferred until the BWIP team meeting on the
afternoon of April 15, 1986 (see 6.0, below).
The consensus of the meeting was that the NWC approach was reasonable and
appropriate and that the initial topics were appropriate, as well. The whole
team agreed that full use of existing performance assessments should be made
and that selected members of the staff and contractors should review specific
topics and plans proposed by NWC.
NWC committed to presenting a general statement of its position in this trip
report and to submitting specific plans for review as they are developed.

Michael Weber, BWIP Site Lead for NRC, chaired an afternoon meeting of the
BWIP team, including NWC, W&A and SNL representatives, as well as WMGT and
WMRP staff. Mr. Weber reviewed the status of the BWIP program and proposed
discussion aimed at preparing for the next BWIP Hydrology Workshop, which is
now anticipated for June or July, 1986. The agenda for the BWIP Team meeting
is included in Attachment 2.
Mike Galloway (Terra Therma) presented a list of perfonmance-related
questions, which are summarized on Figure 3. The principal point of
discussion centered on establishing the need for regional-scale modeling of
the flow system. It was agreed by those present at the meeting that it would
be appropriate for there to be TA contractors present when SNL presents the
results of the Basalt Demonstration Task of Research Contract A 1266,
particularly for the insights that the SNL modeling presents on the
post-emplacement performance of a repository in basalt.
In addition to the topics proposed by NWC, W&A indicated that they had
concerns with respect to data needs for effective porosity and Paul Davis
expressed concerns for evaluating dual porosity and the potentially
directional nature of effective porosity and hydraulic conductivity.
There was an extensive discussion of the need for and potential locations for
information in the regional hydrogeologic setting of BWIP in relation to the
performance evaluation of a repository. This has been a matter for internal

NRC staff and contractor discussion for some time, and NWC anticipates that it
will continue to be a discussion point, reflecting the differing approaches
and experiences of the NRC's BWIP team. Mr. Davis finished the meeting by
presenting some information from the regional modeling conducted to date under
FIN A 1757.

7.0 MEETINGS ON APRIL 16, 1986
On April 16, 1986, Mark Logsdon, NWC Project Manager, met with some NRC staff
and managers, including members of WMGT, WMRP and WMPC, to discuss
miscellaneous matters related to planning and project management of the
contract. Topics included:
o Planning for modeling using the INEL facilities;
o Status of USGS work at NNWSI;
o Quality assurance;
o Proposed NRC FFRDC.
In the afternoon, Logsdon met with Ms. Mary Little, the new Contract
Administrator, to review the billing procedures and the status of NWC contract
modifications and vouchers.
