Transition to Operations Milestones to CD-4 In-Vessel installations and Calibrations to conclude in late March (3/28/2014) to shift activities to the preparations for installing the new centerstack. All Buswork reinstalled in the NTC by mid May. Centerstack, flex bus and umbrella covers in place by late August. Clean/Photo/Close in early September, followed immediately by the initial pump-down. NSTX-U turned over to Operations by mid-October. A limited Centerstack bake is planned for late October. Field Coil Power Testing and the ISTP to CD-4 complete by mid-November. Assumes that a full-bake and some preparations for Physics Operations will occur after CD-4 Vessel Entry? NSTX-U February NSTX-U Team Meeting. Engineering Operations 1 Feb. 11, 2014
Approvals for Operations The NSTX-U Activity Certification Committee (ACC), comprised of representatives from PPPL Engineering, Research, Safety, and the DOE PSO is currently reviewing technical and safety systems for NSTX-U Safety Assessment Doc. (SAD) Design review documentation and chit resolution Interviews with cognizant engineers Plans for pre-operational & integrated system testing Safety/interlock systems Physical walk-downs of equipment Resolution of remedial steps recommended by ACC A PPPL Internal QA Audit of NSTX-U Start-Up Documentation will begin in April 2014. An Operational Readiness Review (ORR) is being arranged through the DOE PSO, and is prerequisite for our safety certificate prescribing allowable operating parameters. NSTX-U February NSTX-U Team Meeting. Engineering Operations 2 Feb. 11, 2014
Preparations for Operations MG#1 Weld Repairs Spider Arm weld repair procedures developed and approved by PPPL Engineering, General Electric Co., and our preferred subcontractor. The Statement of Work has been approved. Actual weld repairs should be completed in ~ 1 month once a contact is in place and crews mobilized. Re-assembly, clean-up, controls testing and balancing complete by September Field Coil Power Conversion (FCPC) Commissioning AC primary Power Systems have been maintained and are ready to support operations Primary power protective relaying is being calibrated and set. 34 new rectifier firing generators have been delivered to FCPC. Testing in progress Electromagnetic fault relaying is being replaced with a PLC based system. New fiber-optics being installed between rectifiers and the Junction Area. All systems should be ready to support individual rectifier power testing by late March. NSTX-U February NSTX-U Team Meeting. Engineering Operations 3 Feb. 11, 2014
Preparations for Operations Digital Coil Protection System (DCPS) Algorithm development for CD-4 is complete. Installation of the new water system PLC in March. Expect to have DCPS hardware and software ready to support multiple rectifier dummy load testing by late May. Power System Real Time Controls (PSRTC) DCPS Algorithms will be applied to the new PSRTC. Simulation models and testing (PTP-034) by June. PF1 Field Changes PF1A Upper and Lower Coils will be powered. PF1B Upper and Lower will not be powered at the start of the run (terminated into resistors and MOV s). FCPC has been configured. Connections/labeling in the test cell still required. NSTX-U February NSTX-U Team Meeting. Engineering Operations 4 Feb. 11, 2014
Preparations for Operations Ip Calculator Concept established and schematics are being developed. All parts are expected to be at PPPL by late March. System testing in May. Operational by end of July. Stand Alone Digitizers (SAD II) Plug in replacements for the SAD I. System FDR in late March. Assembly/testing complete in May. High Harmonic Fast Wave (HHFW) Compliant Center Conductors Testing of the prototype successfully completed in the RF test stand. FDR is scheduled for late February. Work package being developed to remove HHFW components for upgrades in late February. All parts to complete antennas not expected until mid-April. NSTX-U February NSTX-U Team Meeting. Engineering Operations 5 Feb. 11, 2014
Preparations for Operations Neutral Beam #2 Primary power systems and protective relaying being prepared to start power supply testing in March. NB#2 is expected to be ready to pump-down in June. Refrigerator start-up and cryogenic cool-down as early as July. Need to be able to start ion source pre-operational testing (PTP-11) in September to complete the NB#2 CD-4 in November.
