• Scope

• Execution Plan

• Deliverables

• Summary

NSTXU Device • The NSTX device is exploring a

novel structure for the magnetic field used to contain the hot ionized gas, called “plasma”, needed to tap this source of fusion energy. 

• Mission of the NSTX is to establish the potential of the ST configuration as a means of achieving practical fusion energy.

• Not a steady state machine. Pulse length < 6 sec.

• Design rep rate <40 minute

Technical Performance Baseline Parameters (defined in section 2.2.1 of the Project Execution Plan (PEP))

Technical Performance Baseline Parameters

To meet the mission need objective, the existing NSTX machine at PPPL will be upgraded to permit operation at the following increased levels;

• Toroidal field from 0.5 tesla to 1.0 tesla;• Pulse length from ~1.0 second to 5.0 seconds;• Plasma current from 1MA to 2MA;• Neutral beam heating from 5-7MW to 10-14MW

‒ Design basis‒ Day 1 hardware capable (design and tested)‒ Not Day 1 planned achievement (phased in during 2-3 years)

‒ Design basis‒ Day 1 hardware capable (design and tested)‒ Not Day 1 planned achievement (phased in during 2-3 years)

NSTX Upgrade Deliverables1) Double field and current

Center Stack (CS) Upgrade. –Design, build and install new CS assembly including;– a new toroidal field (TF) hub assembly, –new TF flag assemblies, –new ceramic break, –new inner TF bundle, –new ohmic heating coil, –new plasma facing component (PFC) tiles,–new poloidal field (PF) 1a, b & c coils.–Power, controls, water, services

2) Double neutral beam power & more tangential injection2nd Neutral Beam-line (NBL).

• Decontaminate and prepare a TFTR neutral beam-line (NBL) for installation on NSTX.

• Evaluate and refurbish internal components as necessary (cryogenic panels, beam dumps, bending magnets, beam scrapers, calorimeter, etc.).

• Relocate the NBL and • Provide a second set of beam-line services (e.g., power, water, vacuum,

cryogenics, etc.).

This represents a major modification to an existing fusion deviceThis represents a major modification to an existing fusion device

CD-4 milestone completion criteria defined in section 2.2.2 of the Project Execution Plan

(PEP)2.2.2.2 Demonstrated Performance 1.The major milestone marking the transition from a fabrication project to an operating facility is the first plasma milestone (CD-4). First plasma is defined as an ohmically heated discharge > 50 kA at a toroidal magnetic field of > 1 kG. The operations phase will resume upon completion of the first plasma milestone.2.The installation of the second neutral beam on NSTX shall be considered complete at the stage where each item below has been demonstrated:a.Beamline water, vacuum, cryogenics, and feedstock gas services have been attached to the beamline;b.A Torus Isolation Valve and duct interconnects the NSTX vacuum vessel and the neutral beamline;c.Local Control Centers have been powered on to monitor power supply status, and;d.Project will be verified as complete when a 40,000 electron-volt beam has been produced and injected into the armor for .050 seconds

Summary

• Technical Performance Baseline Parameters as documented in the PEP and GRD’s were the basis for the project design.

• Execution of project scope followed a disciplined and auditable process following mature PPPL Procedures.

• Startup of NSTX (OP-NSTX-02) and start of ISTP (OP-NSTX –

ISTP-01) marks the turnover from construction to operations.

• Conclusion of the construction project will be achieved as defined in the PEP Demonstrated Performance.

• Construction is almost complete. We will be ready to operate
