1. INTRODUCTION This specification describes the NSRRC requirements for design, manufacture and inspection of the

beamline liquid-nitrogen (LN2) transfer system.

Taiwan Photon Source (TPS) at National Synchrotron Radiation Research Center (NSRRC) Hsinchu,

Taiwan, requires one (1) liquid-nitrogen (LN2) transfer line and twenty-six (26) branch lines with

twenty-six (26) control valves for the beamline (herein named as BL LN2 transfer system). Figure

2CR-1-LN2-LAY001-01 shows the layout of the BL LN2 transfer system. The BL LN2 transfer system is

composed of two separate lines LN2-TL1 and LN2-TL2, which connect to the main transfer line LN2-TL

through two cryogenic valves CV004 and CV005, respectively. The main transfer line, which connects

the LN2 storage tank at the source side and the phase separator of volume 1000 L at upstream of the

manifold for the cryogenic system and the SRF cryomodule, is now under construction and will be

completed in year 2013. There will be 24 beamlines constructed eventually, and each beamline requires

an independent LN2 supply. In total, 26 control valves are required to isolate the 26 branch lines. Because

of space constraints, the branch line can be located only on the elbow for the beamline. Figure

2CR-1-LN2-DISCV-01 shows the Distribution of the Control Valves. Control valves CV210 and

CV211-1 are to retain the possibility for LN2-TL1 and LN2-TL2 to be a backup of each other. The

capacity of the LN2 storage tank is 60 m3 with maximum operating pressure 6.0 barg. The required

consumption of LN2 for each beam line is 30 L/h.

To verify the integrated performance, the heat load of the BL LN2 transfer system should be

measured experimentally after installation on site by an evaporation approach. The calculated heat load

shall be better than 960 W. The measured integrated heat load shall be less than 1010 W. The defective

purchase with a price decrease shall be assessed at an amount to be calculated on the basis of 1 per cent of

the total Contract Price for each one watt (1 W) increase of the required performance (1010 W). For

instance, a total measured heat load 1020 W shall result in a price decrease 10 per cent of the total

Contract Price. If the measurement of the heat load exceeds 1060 W, the Contract shall be terminated for

default.

(2) NSRRC reserves the right, on four-week notice, to perform an audit at the Vendor factory based on the

above standard, and to conduct any tests or QA-measures at the Vendor’s site or that of its

subcontractors. The use of this right does not release the Vendor from its duties under the contract.

(3) The Vendor shall send a detailed schedule for the assembly and testing addressing the assembly of the

major components of the BL LN2 transfer system to NSRRC at least six (6) weeks before the work

commences. NSRRC reserves the right to observe the assembly and testing of the BL LN2 transfer

system at the Vendor’s facilities. NSRRC will then decide and inform the Vendor which assembly and

testing steps they seek to review.

(4) Before production, the Vendor should submit a full set of drawings to NSRRC for approval. No

production shall begin without the prior written approval of NSRRC.

(5) NSRRC reserves the right to make changes in the design, as may be necessary or desirable, after

signing the contract. Any difference in the contract price and the delivery period resulting from any

such change shall be agreed upon in writing by the NSRRC Technical Representative before

proceeding with the work. Before proceeding with the work involving possible claims by the Vendor

for compensation and modification of the contracted price, the Vendor shall submit in writing a

proposal to show NSRRC the impact on the cost and schedule for such work. When NSRRC desires to

have work performed and a price is agreed upon, such work will be covered by a written change order

issued to the Vendor by NSRRC. The Vendor shall NOT proceed with any such work before receiving

a written NSRRC change order.

Ver. 04, Aug/30/2013 Page: 10/17


9. TRANSPORT (1) The Vendor takes full responsibility for the transport, schedule and insurance coverage of the delivery

of the individual components of the BL LN2 transfer system to the NSRRC job site (DDU to NSRRC

job site). It is the Vendor’s full responsibility to deliver the equipment to the NSRRC job site intact

and ready for installation.

vibration. Special arrangements for transport shall be made for components sensitive to shock or

vibration. The equipment must be packed properly and protected with shock-absorbing material. One

continuously recording shock detector (for which the G-factor can be set manually) shall be mounted

on the base, and two permanent tilt indicators shall be attached to the shipping crate by the Vendor. If

the Vendor finds another way to sensitive to shock and vibration during transport, the Vendor should

propose the method during the Detail Design Review meeting for approval. The Vendor shall report

the recording log to NSRRC within one (1) month after transport and delivery.

(3) The Weka valves shall be shipped on-site of NSRRC for inspection after Vendor has purchased (The

shipping cost shall be paid by Vendor). The NSRRC shall delver the accepted Weka valves to Vendor

arrival can signal shipping damage, a leak or both. The equipment must have a secured (wired closed)

valve to allow the pressure measurement upon arrival. Shipment with a pressure gauge in place must
