Official Project Title is :

Tritium and Thermofluid Control in Magnetic and Inertial Fusion Energy Systems

Abbreviated Designation was Agreed as :

TITAN ProjectTritium, Irradiation and Thermofluid for America and Nippon

What is TITAN?

April 2007 to March 2013

To obtain fundamental understanding for establishing tritium and thermofluid control throughout the first wall, blanket, and heat exchange/T-recovery system of MFE and IFE systems by experiments under specific conditions to fusion, such as irradiation, pulse high heat flux, circulation and high magnetic field.

The results will be applied through the integrated modeling to advance-ment of design for tritium and heat control of MFE and IFE systems.

Objectives of the TITAN Project

The JUPITER-II Project focused on key technologies for advanced blankets

The TITAN Project will focus on consistency of the blankets with first wall and recovery systems with respect to tritium and heat control

There was a story relating to IFE before starting TITAN in Japan

1. Two proposals were almost equally scored when selecting post-JUPITER-II project in Japanese selection committee.

TITAN program (no particular emphasis on IFE)IFE physics program

2. The committee suggested to merge the two proposal. A combined project were once planned. (IFE physics + First wall physics/technology + Blanket/Material engineering) But this was not accepted by the US side.

3. After repeated discussion in Japan. TITAN was accepted as the next Project but at the same time, inclusion of IFE technology into TITAN was requested.

Negotiation with the US side1. US has very small funding on IFE technology program. Thus

matching fund for IFE technology is not available in TITAN.2. This means we cannot start IFE technology research in

TITAN with budget.3. Technology common to MFE/IFE can be enhanced.

Collaboration on IFE technology for initial two years1. Application of the on-going research for IFE by each Task2. Enhance assignments to the US relating to IFE technology 3. More effort may be initiated in the third year (from April 2009)

including some budget allocation – within “fine tuning” range. 

4. Re-planning after the mid-term review (May 2010)

IFE Technology Activity in FY 2007 and 2008

1. FY 2007Assignment of K. Tanaka and Y. Hirooka (by another budget)Some support by Japanese domestic budgetTanaka recommended Tillack and Hassanein as IFE liaisons of the US side. US side nominated Tillack as IFE liaison (FY 2008)

2. FY 2008Assignment of K. Nagai to SNL for IFE related researchMFE/IFE Common Technology Workshop for further planning

Research on issues common to MFE and IFE is encouraged. Those specific to IFE is not encouraged.Common interest by the both side, uniqueness of the research which is not possible in Japan, and matching fund are the fundamental requests for the collaborationAn experiment which can cover both MFE and IFE parameters are encouraged.Theory/modeling is always encouraged.

Pulse heat conditions for MFE and IFE

What is the guideline for planning collaboration on IFE technology ?

Workshop Goal

1. Understand the status of IFE technology activity in the US and Japan

2. Define contribution of TITAN activity to MFE/IFE (tritium, thermofluid, materials --)

3. Planning of collaboration (tiny budget) for FY 2009 and beyond
