FESAC Charge FESAC is asked by FES to undertake a new long-range strategic planning activity for the Fusion Energy Sciences (FES) program. From the charge to FESAC: The strategic planning activity to encompass the entire FES research portfolio (namely, burning plasma science and discovery plasma science)- should identify and prioritize the research required to advance both: the scientific foundation needed to develop a fusion energy source, as well as the broader FES mission to steward plasma science. The FESAC activity in addressing this charge is to commence after the completion of community-led activities to provide broad input to this long-range planning. 3 PPPL CPP Preparations / NSTX-U MFS Weekly Meeting, 01 April 2019 / H.

FESAC Charge, contd. In developing recommendations within this long-range strategic planning activity, FESAC should take into account the following aspects: Identifying specific research areas, across the entire FES portfolio, in which the U.S. should establish or enhance global leadership. Maintaining a healthy and flexible program, which incorporates the roles and contributions of universities, national laboratories, and industry, to deliver science results throughout the next decade. Maintaining, upgrading, and/or pivoting current small-, mid-, and large-scale facilities, including DIII-D and NSTX-U, and also initiating new experiments/facilities/projects. Identifying international collaborative opportunities or partnerships that can give U.S. scientists access to devices outside of the U.S. with unique capabilities. Providing support for private-public partnership ventures. Positioning the U.S. to obtain maximum benefits in the ITER burning plasma science era. Considering the future budgetary constraints described below, as well as the technical readiness and feasibility for any activity to proceed. 4 PPPL CPP Preparations / NSTX-U MFS Weekly Meeting, 01 April 2019 / H.

FESAC Charge, contd. Specifies three 10-year (2022-2031) funding scenarios, with the FY 2019 enacted budget for the FES program as the baseline: FESAC Funding Scenarios 900 800 $740M 700 600 500 $M 400 Scenario 3. Unconstrained (prioritized list) Scenario 2. Modest (2%/yr) growth 300 Scenario 1.

PPPL Perspectives on the NAS Report It s exciting- calls for continued partnership in ITER and charting a path to fusion electricity. In recommending a path to a compact pilot plant, it reflects what the NAS panel heard from the community (including PPPL), in terms of what is exciting and what is needed to energize our field. The path must depart significantly from an ITER-extrapolation path such as the EU roadmap. We must chart a path that embraces innovation. In preparing for the Community Planning Process, a key question (as yet unanswered at PPPL) is, What would we like FESAC to recommend when it issues its report in December 2020? 6 PPPL CPP Preparations / NSTX-U MFS Weekly Meeting, 01 April 2019 / H.

Our Task Develop initiatives that are responsive to the FESAC charge and are able to gain widespread community support and eventual consensus. Fusion Non-Fusion Initiative Tokamaks Stellarators Credible Codes Technology / Virtual Eng. V. Riccardo Liquid Metal PFC Participation in ITER PPPL Leader W. Guttenfelder D. Gates S. Hudson Initiative Plasma Astrophysics Low Temperature Plasma High Energy Density Plasma PPPL Leader H. Ji Y. Raitses W. Fox R. Maingi R. Nazikian We are developing the mission need case for each initiative. 7 PPPL CPP Preparations / NSTX-U MFS Weekly Meeting, 01 April 2019 / H. Neilson
Fusion Initiatives Being Incubated at PPPL (1) Tokamaks Integrate in successive steps. Two-step strategy - Step 1, SHPD: integrate a high-performance DD plasma, a compatible plasma exhaust/PMI solution, plasma sustainment. - Step 2, Pilot Plant: integrate all of the above, plus DT, energy conversion, breeding, tritium fuel cycle. Stellarators Continue to develop the compact stellarator based on quasi-symmetry, folding in post-NCSX advances in plasma/coil optimization, divertors, and materials. Construct a large-scale, compact optimized stellarator. Credible Codes Develop a comprehensive suite of tokamak and stellarator analysis codes, to be made available to design teams, whether government- or privately financed. Strategy: fundamental research in physics and mathematics, training in modern software engineering, verification & validation of codes, documentation, high quality visualization both for scientists and public. 8 PPPL CPP Preparations / NSTX-U MFS Weekly Meeting, 01 April 2019 / H.

Fusion Initiatives Being Incubated at PPPL (2) Technology / Center for Fusion Pilot Power Plant Design Coordinate / integrate fusion design activities nationally. Investigate designs for future devices Pursue advances in fusion technology through a combination of virtual and physical engineering. Liquid Metal PFCs Update initiative presented to FESAC in 2014, then described in three thrusts: - Science and technology of liquid PFCs - Fundamental liquid metal surface science - Deployment in confinement devices Fold in guidance on R&D needs from recent System Study of Liquid Metal PFCs for fusion reactors. U.S. Participation in ITER Toward full partnership in ITER construction, research, and operation. Maximizing the benefits our investment in ITER. 9 PPPL CPP Preparations / NSTX-U MFS Weekly Meeting, 01 April 2019 / H. Neilson
Non-Fusion Initiatives Being Incubated at PPPL Plasma Astrophysics Drivers: established grand challenge questions, abundant data availability, maturity of plasma physics, advances in computing power and experimental techniques. Investments in in observation, theory/numerical modeling, laboratory experiments, Low Temperature Plasmas Establish a user facility based on extensive diagnostics available at PPPL and Princeton University, experienced theory and experiment staff. Many potential users. Research directions include 1) Interfacial plasmas, 2) Plasma-solid state interactions, and 3) Coherent structures. High Energy Density Plasmas Understand and use strong B fields in HEDP experiments. New physics: 1) Lab astro with stronger fields, 2) Plasma transport across B fields, 3) Magnetized Rayleigh-Taylor, 4) Plasma waves with strong B (?) 10 PPPL CPP Preparations / NSTX-U MFS Weekly Meeting, 01 April 2019 / H.
