!  How to access

•  Two ways to access to the UL

" Elevator(cage) in the shaft

For the 730m access tunnel the passenger can use a

battery car

"  Lamp way with car It takes 30 min for one way

length Velocity Time required (one way)

Payload Inner size (W x L x H)

587 m 2 m/sec ~ 5 min 1 ton 1 x 2 x 3 m3

!  The Safety

•  Refuge will be placed for variable emergency near the front of UL

" It is going to be not only one " Operation plan has not been made yet

•  Fire shutters will be employed at the all connection points •  The design of two seperated experiment halls can give big advantages

in safety against emergency situations •  In case of variable specified emergency, we will follow special instructi

on which will be composed by CUP

Refuge (>100m2)

!  Provide of the fresh air

•  Flowing "  The air-intake will be started at the middle of the shaft "  The flow rate is going to be ~ 7,840 m3/hr (130 m3/min)

Equip.

Clean rooms

Pumping to surface

•  Underground water will be supplied to underground labs for DI, PCW, washing and so on. •  The main sump will be placed at the front of each experimental hall

11

!  Supply of Radon free air


Surface air

Surface air (extra)

Rn free air sys. 1 (120 m3/hr)

Rn free air sys. 2 (Option)

HPGe Clean room

Clean room

•  Input air is coming from surface •  Rn free air is provided to not whole room but only small enclosed box or equi

pment •  Y2L Rn free air system(120 m3/hr) will be moved to the new UL

Hall A

Hall B

150~200m long

!  The networks

On the

•  Telephone network will be equipped independent from internet for emergency •  Ground office and underground laboratory are physically connected single private netwo

rk with dedicated optical firers. A target speed of this dedicated line is 10Gbps •  Researchers and staffs can access the private network through VPN from outside of lab

oratory

13

!  Summary


•  After contract with Handuk, the enforcement design will be started in earnest

•  There are many things to be concerned before starting enforcement design

" Electric power (wattage)

" How much of Rn free air is going to be good

" Optimal size of each room

•  We need many good information & knowhow of world underground laboratories

"  (safety) In case of fire … how to put out … is any special system for it ?

"  (providing gas) How to support the liquid He, N to far labs

"  (electricity) What is efficient way to build clean ground…

"  (construction) What kind of things did you miss in UL construction …

Which you should have done something…

" (Rn free) How to efficiently make a Rn reduction system …
