Date: August 2, 2011 (Pilot Plant Diagnostic Integration Peer Review)

FINAL REPORTS



BACKGROUND 

Diagnostic performance and integration are critical issues for future fusion nuclear facilities, such as CTFs, Pilot Plants, or Demo, because of the high level of plasma control expected.  Diagnostic space requirements compete with requirements for heating and tritium breeding.  The measurement requirements and nuclear environment constrain the diagnostic technical solutions.

In order to obtain a better understanding of these issues and their design implications for future machines, a study has been undertaken within the framework of PPPL's pilot plant activity.  The study will examine diagnostic integration issues for  advanced tokamak (AT), spherical tokamak (ST), and compact stellarator (CS) pilot plant options.  To date, progress has been made in developing measurement requirements and system selection for only the AT and ST machine configuration designs. An integration approach is being developed, using ITER as a guide.  The purpose of this peer review is to obtain feedback from experts on the choices being made and the plans for completing the study.

CHARGE

For the AT and ST:

  1. Have the appropriate plasma measurement requirements been identified?
  2. Have the appropriate diagnostic system choices been made?
  3. Are the diagnostic space allocations and machine integration approaches reasonable?
  4. Have the key performance and integration issues been identified?

LOGISTICS / DOCUMENTATION

Reviewers and observers are asked to submit their comments and unresolved concerns in the form of chits.
