ARIES Documents -- Meetings ArchiveARIES Conference Call, 11 May 2007
Documented by L. Waganer
(Reminder:) The next ARIES-TNS meeting will be held on June 14, Thursday afternoon, and the morning of June 15th at GA. This meeting will follow the Advisory meeting held on the afternoon of 13th June and the morning of the 14th of June.
Wrap-up of ARIES-CS Final Report Papers
Rene Raffray noted that ANS has received all the papers except for the overview paper, which is being written.
Advisory Committee Meeting Planning
Ken Schultz reported that most of the advisory team has been contacted and many are planning on attending. He is hoping to get a few more attendees to participate.
Status of Action Items for the ARIES-TNS Study
1. Systems Code Development - Zoran Dragojlovic said the development of the code is progressing with some early benchmarking results completed. He has completed the modeling of the power core and has completed adding the existing ARIES cost model algorithms. He has used this to generate costs for the major accounts using the ARIES-AT data. He then compared these data against the published AT data with reasonable agreement. There were a couple of algorithms that were incomplete. Following a benchmarking, he will begin to add new algorithms supplied by Les Waganer.
He has modeled the code in C++ as it is easy to work with and has an equivalent run time. He is using the main elements of the ARIES code, Version 3.10 associated with ARIES-SPPS.
2. Updated cost algorithms as input to system code - Les Waganer reported he is working on the costing algorithms. He has provided the cost of the Land and Land Rights (20) and will soon have the Structures and Site Facilities (21) defined.
3. Provide blanket definition and parameters - Xueren Wang said he is updating the power core and assessing the pumping power and thermal parameters that determine the thermal efficiency. Next week he hopes to have a better definition. Laila is working on the radial build for the LiPb/SiC blanket concept. The radial build will represent both a section view through the coils and between the coils at maintenance ports.
4. Choice of FWBD materials to accommodate heat flux and temperature of heat removal media for divertor and blanket - Rene Raffray said there was not much progress on this issue and he needs to talk to Said Abdel-Khalik to plan the work scope.
5. Provide input on coil material and parameters to system code - Leslie Bromberg has been talking to Rene Raffray about the coil geometry and structural provisions. He is getting the structural analysis tools in place. He intends to have the ability to assess HTS, NbTi, and NbSn superconducting coils.
6. Assess implications of waste treatment on power plant design requirements - Laila El-Guebaly mentioned that she has provided the current recommended requirements at the previous meeting and no additional work has been accomplished.
7. Assess impact of power core component design choice on reliability, availability and maintainability (RAM) - Les Waganer said he has been seeking advice from Boeing RAM experts on possible improvements and approaches.
8. Evaluate impact of tritium breeding and recovery on fuel management, safety and cost - Phil Sharp has defined a small team to work on this issue. He intends to have a meeting in June to define the fuel management requirements. He is working with Laila El-Guebaly on the TBR to tailor it to the requirements. There was a big discussion about the precision of the TBR predictive capabilities.
Working groups on critical issues - Mark Tillack identified topics that might warrant further investigation in technical working groups. The participants on the final list were: Power Management (Tillack/Raffray), Tritium Management (Sharp), and Plant Operations (Waganer). Each of these topic areas would have a small team to develop a scope of effort and possible planning for future R&E efforts to mitigate future plant operations.
