Actions Accomplished (dated 5/15/06) |
| Bromberg |
10-May |
Coil
Structural Material Choice - Determine the coil
structural material based on Lailaâs activation analysis and forward to
El-Guebaly and Waganer. |
Bromgberg: Decided on JK2LB material that will be used on ITER Center
Solenoid. Assume same strength allowables. |
| El-Guebaly |
10-May |
ÊRevise Radial Build at
Minimum Plasma to Coil Separation ö (Per Laila,
there seems to have been an error in the systems code and Jim is correcting
the error. For the 7.75 m machine, the minimum separation distance should be
1.3 m, not 1.21 m as mentioned at the meeting.). Need new 7.75 m strawman
from Jim |
Jim
Lyon is stuggling to obtain a 7.75 m solution. Several approaches were
offered and will be tried. If successful, he will forward the new 7.75 m
strawman to Laila by 19 May. |
| Ku |
10-May |
ARE
Coil and Plasma Geometry ö Provide Coil and Plasma
geometry in IBP format to X. Wang. |
Long
Poe Ku is holding off pending the Lyon solution. Then it will take about a
week to generate coil and plasma geometry. |
| Lyon |
10-May |
Provide
Neutron Source Profile to Mau and Wilson ö Will aid in
definition of the divertor and the NWL calculations |
Jim
said that the Peak neutron source profile will be provided after he issues
the strawman.
|
| Lyon |
10-May |
Check
Delta-Min Used in Code ö Determine if the code has a
separation distance of 1.26 m for the R=7.5 or 7.75m machine. |
The
error was found and fixed. Delta-min now matches Laila's and Long-Poe's
values. |
| Lyon |
10-May |
Check
Power to the Divertor - Should include alpha power (~ 41
MW extra) |
Jim
said this alpha power was correctly modeled in the code and the April 06
slide was in error |
| X. Wang |
10-May |
Coil
Structure Thickness Estimate - Based on present coil
structure stress analysis, estimate recommended thicknesses for intercoil
structure and strongback structure for each general stress region and percent
of total area covered.Ê (For example on
intercoil structure,Ê 0-20 MPa, 5 cm
thickness, 35% of area, 20-40 MPa, 10 cm thick, 20% of area, and so on.Ê Ditto for strongback.)Ê Then include penetrations and sum and
average for intercoil and strongback structure thicknesses. Multiplying these
by respective areas and densities would yield Coil Structure mass. |
Xueren
analyzed the stress and deflections (for the 7 m case), estimated the local
thicknesses and then provided average thicknesses of 20 cm for the intercoil
structure and 48 cm for the strongback structure. An additional question
regarding neutronic shielding arose later about the average thickness of the
outboard inter-coil structure which is estimated to be about 16 cm and 28 cm
for the outboard and inboard structures, respectively.

15-May |
VF
coil Definition ö Need to add to core definition and code
assessment |
Long
Poe KuÊ provided a set for the 7.5 m
configuration which can be scaled as necessary. |
| Mau |
15-May |
Modify
Divertor Plate Analysis to R = 7.75 m machine ö Need
baseline assessment |
Mau
will do a manual estimate of divertor by Friday, 19 May |
| Mau |
19-May |
Define
baseline divertor solution ö Provide physical location of
divertor and average and peak heat loads. |
TK
will do a manual estimate of divertor coverage fraction by Friday, 19 May. He
will send the divertor location to Xueren to include in the CAD drawings. |
| Najmabadi |
19-May |
Provide
definition of Vacuum Pumping System - This will be
helpful in providing additional credence to cost definition. |
|
| Waganer |
19-May |
Resize
the maintenance transporter. |
Waganer is working on thisÊ |
| Wang |
19-May |
Generate
CAD drawings for all components, including divertor system and penetrations. Send input file to UW. Need radial build from Laila. |
Wang
is working on this area.Ê He needs the
transporter and HS sizes. |
| Wang |
19-May |
Provide
some definition of main FPC support structure ö This will
be helpful in providing additional credence to cost definition. |
Wang
will generate this data. |
| Wang/Waganer |
19-May |
Define
Reactor Building Content and Sizes ö Provide definition
and volume of the Reactor BuildingÊ |
Waganer
and Wang are working on this definition |
| Waganer |
25-May |
Availability
Value ö With the baseline maintenance approach, analyze
the maintenance actions and estimate the likely 10th of kind plant
availability.Ê Until this value is
provided, assume an availability of 85%, e.g., ARIES-AT. |
Waganer
has started on this |
| Waltrop/Waganer |
25-May |
Coil
Structure Fabrication Approach and Cost Estimate -
Determine if chosen coil structural material is suitable for Arc-Deposition
fabrication. Develop a cost estimate for the coil structure. |
John
Waldrop, Boeing, has joined the team and participated in the call. He has
started looking at the requirements Waganer has generated.ÊÊ |
| Wilson/El-Guebaly |
30-May |
Update
NWL distribution for 7.75 m case ö Needed for divertor
and TBR calculations. Need neutron source profile from Jim. |
|
| El-Guebaly |
30-May |
Define
radial build for LiPb/SiC system. |
Laila
will provide it after issuing the reference LiPb/FS/He radial build. |
| Lyon/El-Guebaly/Wang |
30-May |
Determine
Replacement Component Cost ö Determine the cost of the
blanket and divertor segments. |
The
average size of blanket is 2 x s 2 m and the largest is 3.9 m high. |
| Wilson/El-Guebaly |
June-July |
Perform
3-D Neutronic Analysis. Need CAD input file from
UCSDÊ for 7.75 m machine, including
blanket variation, non-uniform SOL, divertor system, and penetrations. |
Wilson
and El-Guebaly is holding off pending the Lyon solution. |
