Preliminary Basic Planning

• Expected Output• Basic arrangement plan (1:10,000 topographical map)

‒ Evaluation of geological condition (active fault, earthquake, ,)‒ Determination of DH Location (including elevation)‒ Layout of the Beam Line route and elevation

• Access way to Detector Hall (HT and VS)• Review the cross-section for the main part (include BDS)

• Investigation• Topographical survey (already done)

‒ Topographical mapping 1:10,000 (result by aviation laser survey)

• Geological investigation‒ Borehole investigation with logging test (near IR point /100 ～

150m ）‒ Geophysical exploration (500 ～ 1000m)


Required ADI Information

• Expected Input (for facility arrangement)• Determination of DH Location

‒ IR point (including elevation)‒ Layout of the Beam Line route and elevation

• Access way to DH (Vertical or Horizontal or,)

• Expected Input (for Cross section)• Decision of the Cross-section for the main part

‒ BDS Beam Line Layout & Cross-section‒ Shield Wall thickness in ML-tunnel (Sanami-san reported)

• Cryogenics Equipment layout‒ Arrangement of He-Tank & Cold box‒ Anti-vibration measure of the Compressor

• Install Method to MLT (include AH Cross-section)‒ Cryomodules & RF, Cold box


Near Term Activities : 1

１ Decision of Facility arrangement

■ Determination: IR Point


• Revision the DH Configuration (TDR)• Access Facility to DH (VS & HT)• Underground Facilities Layout and configuration

■ Determination: Surface Facility Layout

• Surface Facilities planning (Assembly hall)• Kick off some kind of Investigation (Topographical survey, Environmental Assessment)• Consultation with regional society

In Basic planning stage

2 Decision of Facility arrangement

■ Determination: Beam line level (elevation)

■ Determination: BL Route and Length


In Basic planning stage

• Revision the Access Point (AH & AT portal)• Access Facility to ML (AT length & location• Consistency with surface environment

• Vibration Impact Evaluation (Artificial, Separation from Riverbed)• Access Facility to ML (AT length & location• Groundwater treatment (Natural Drainage system)


3 Decision of the basic facilities plan

■ Specific study of Power equipment (Central power receiving facility)


In Basic planning term

• Location of the Central Power Station• Power voltage, power receiving system • Consultation of Power receiving line• Negotiation with local power company• Planning the emergency power system


■ Specific study of Cooling water system, Air-conditioning system, and

4 Decision of the basic facilities plan


In Basic planning term

• Finalize the Heat load capacity • Cooling water system (cooling tower, chiller )• Exhaust, Smoke facilities in the emergency• Facility planning in BDS & Detector Hall


■ Measurement of regular vibration

Medium Activities

Summary


1. The specific engineering design depending on the Kitakami site conditions has started by unification of the site.

2. We need some reviews about Asian TDR configuration in the preliminary planning stage.

3. Important issue in the near term is the determination of IR point(DH) and Beam Line layout(BDS).

4. Surely doing a technological design at the basic planning phase enables shortening at the design period.5. Minimum geological survey is required to concrete the basic plan toward the design phase.6. We can push forward preparations for site acquisition and the environmental assessment by early determination of the every access point.
