Meeting 4 Action Items
next APEX meeting will be held during the period November 2-4, 1998, at
complete and detailed conceptual design is expected during Phase I of the
study but rather, effort should be focused on ideas and scientific basis
each proposed concept.
key issues for each concept be identified and added to the Basic
needed for each concept
interim report on the scientific bases and preliminary analyses of the
under consideration is due March, 1999.
Adequate analyses on each concept should be completed as early as of
1999. The Scientific Evaluation process is also scheduled March 1999. )
raised that this date is too early. It was also suggested that the
Group include those individuals who will undertake the Scientific
suggested that a community workshop could be held just after the Interim
is issued and before the Scientific Evaluation is performed. One
to have the Interim Report out for distribution by July 1, 1999, and hold
community workshop after that date and have the Scientific Evaluation be
performed by September-August, 1999. This is under discussion and will be
finalized before or on the next APEX meeting.
should be prepared to submit abstracts to the upcoming ISFNT-5 Symposium
(headline July, 1999).

suggested that we start developing these criteria and send them to people
comments. He specifically indicated that the Scientific Evaluation should

Defining major technical issues and uncertainties.
failure analysis is not needed at this point but rather a qualitative
to mitigate failure is needed. Abdou suggested that INEL to help in
start-up as an issue under hydrodynamics issues
should look into how the FW liquid responds to plasma changes and
of dynamics and heat transfer properties of particulate flow in a vacuum
heat exchangers should be emphasized in the Li2O particulate concept
pages on this is needed – Mark will get a code that deal with this
generation from particulate and distribution is an issue that should be
to the Li2O particulate concept.
the Materials Group, the following was decided:
fracture toughness to the list of issues
effect of transmutation on material properties
SS304 to material data bases
property data base for a preferred W allot
into making cost prediction based on “typical blanket” rather
costs of coolants to database.
need a reference FRC design. APEX will not develop a design. We have
funds to get from the FRC community a reference design (Abdou).

However, it was emphasized that some changes in tasks/resources may take
