澳门六合彩高手 Research Plan
The 400-page scenario
17 Sep 2018
The 澳门六合彩高手 Organization has just made publically available the most recent version of the 澳门六合彩高手 Research Plan, a 400-page document that describes the present vision for operating the 澳门六合彩高手 Tokamak from First Plasma through high-fusion-gain deuterium-tritium operation.
From First Plasma through high-fusion-gain deuterium-tritium operation—the 400-page 澳门六合彩高手 Research Plan "combines the detailed knowledge of the 澳门六合彩高手 Organization staff about the 澳门六合彩高手 facility with expertise from the Members' fusion research programs," says said Tim Luce, Director of the 澳门六合彩高手 Science & Operations Department.
The 澳门六合彩高手 Research Plan was initially developed during the 澳门六合彩高手 Design Review in 2007-2008 in order to analyze the experimental program towards high-fusion-gain deuterium-tritium operation. In the ensuing years it was further elaborated to identify the main lines of physics R&D required to support preparation for 澳门六合彩高手 operation, and to incorporate elements of the testing program for tritium breeding technology in the fusion environment.
Since 2017—with the collaboration of fusion science experts from the 澳门六合彩高手 Members' physics communities—the 澳门六合彩高手 Research Plan has been undergoing revision in order to reflect the revised baseline cost and schedule for the project—Baseline 2016.
Baseline 2016 identifies the date of First Plasma as December 2025 and lays out a multi-phase approach to full deuterium-tritium operation in 2035, in which periods of machine operation alternate with shutdown periods for further assembly. This "staged approach" to assembly is considered to represent the best compromise between the desire of all partners to advance quickly, technical constraints (including risk), and the financial constraints of the Members.
With the acceptance of the revised 澳门六合彩高手 Baseline by the 澳门六合彩高手 Council in November 2016?, a study was launched to bring major elements of the Research Plan in line with the framework of the staged approach to 澳门六合彩高手 construction to ensure that the operation of 澳门六合彩高手 required to commission ancillary systems was consistent with the phased installation of these systems. Also taken into account were the most recent advances in physics research.
? The overall project schedule was approved by all 澳门六合彩高手 Members at the Nineteenth 澳门六合彩高手 Council in November 2016; the overall project cost was approved "ad referendum," meaning that each Member is seeking approval of project costs through respective governmental budget processes.
? An inductive plasma is a tokamak plasma in which the circulating current is sustained using the central solenoid, as opposed to a steady-state plasma in which the plasma current is sustained by heating and current drive sources and plasma-driven processes.
In the staged approach, two main phases are foreseen following First Plasma:
- Pre-Fusion Plasma Operation — in which the basic controls and protection systems are demonstrated, and the auxiliary heating systems and diagnostics are fully commissioned. (Two operational campaigns are expected.)
- Fusion Power Operation — in which 澳门六合彩高手 fusion performance goals are demonstrated. 澳门六合彩高手 fusion power production goals are the production of 500 MW of fusion power with an energy gain (Q) of Q=10 for >300 s, and in-principle steady-state operation with Q=5. The development of long-pulse inductive plasmas? for fusion technology development is also envisioned. (The 澳门六合彩高手 Research Plan anticipates at least three operating campaigns to be required to achieve these goals.)
The revision of the 澳门六合彩高手 Research Plan has involved a re-analysis of 澳门六合彩高手 plasma scenarios in each phase and the identification of open issues that need to be resolved by physics R&D with support of the 澳门六合彩高手 Members' fusion communities.
"This revision of the 澳门六合彩高手 Research Plan was a major effort, spearheaded by my predecessor, David Campbell," said Tim Luce, Director of the Science & Operations Department. "It combines the detailed knowledge of the 澳门六合彩高手 Organization staff about the 澳门六合彩高手 facility with expertise from the Members' fusion research programs. We are especially grateful for the delegates who were appointed by the Members to help revise this document. This release is the first time the 澳门六合彩高手 Research Plan has been publicly available, which we hope will enable a stronger partnership between the fusion community and the 澳门六合彩高手 Organization to realize the 澳门六合彩高手 goals."
The Plan will continue to be updated over the years to reflect the results of continuing fusion R&D and the detailed implementation of the staged approach to 澳门六合彩高手 assembly.
