Keypoints for TDP2 Design Concepts
Cost Reduction from RDR
 (Deep) Single-Tunnel Accelerator Configuration
Should be harmonized (balanced) with
Applicability to Site and Environmental Conservation
 Less surface facilities and plants
Life Safety / Accessibility to Underground Accelerator
 Enough evacuation / access passages
Risk reduction for tunnel excavation
 Heading for the main accelerator tunnel
Advantage of Topology
 Spontaneous drainage of sump water

Contents of the TDP2 Design Concepts
Single-Tunnel Accelerator Configuration
 Focus on the DRFS scheme
Less surface plants and facilities
 Avoid large-scale site developments
 Reduce access shafts/tunnels from the ground
Enough Access / Evacuation Passages
 Keep a sub-tunnel along the accelerator
 Connection to the accelerator every ~600 m (4 Cryostrings)
 Limit the use for only transport and non-active utilities
Heading
 Keep sub-tunnel excavation 500~2000 m ahead
Spontaneous Drainage of Sump Water
 Raise tunnel elevation to/above valley bottom
 (The accelerator partly appears near/above the surface ground.)

Drainage of Sump Water
No exact sump water data along the tunnel routes.
0.018-0.84 (av.~0.2) m3/min/km is the value for existing tunnels in similar geology (Japan Tunnelling
Association, 1983).
Key points: Avoid radioactivation, High maintenablity, Reliability, Low operation cost
Spontaneous flow

Transport of Sump Water
~300 kW is necessary electricity for the sump water treatment.

Civil Cost Reduction (preliminary estimates)
Asian Civil cost will still be reduced in TDP2 even if we take care more of
environment, life safety, accessibility, excavation risk, sump water, etc. …

Asian CFS Review
To start TDP2, the Asian CFS Team would
invite reviewer (M. Ross, V. Kuchler, J.
Osborne, and necessary experts) at an early
date (in May or June). (under planning)

Global Design Effort - CFS
Summary
(1) In TDP2, the Asian CFS team will make a regional
activities based on the Single-Tunnel Accelerator
Configuration, focusing on the DRFS high-level RF
system.
(2) The regional design will be developed taking
account of not only cost reduction but also wider
site applicability, life safety, environment
conservation, risk management, etc.
(3) Preliminary study by AAA CFS Working group
helped us to find a direction by which the above
goals will be achieved.
