2 Introduction

Thomas Jefferson National Accelerator Facility (TJNAF) is a nuclear physics research laboratory seeking production of thirteen (13) Cryogenic Interface Cans (CIC) for use on the Electron-Ion Collider (EIC)

Project. The CIC is an essential component of the EIC 591 MHz Single Cell Cryomodules (591 CS) which serves as an interface between the cryogenic helium transfer lines and the 591 SC module. The CIC hosts cryogenic piping, valves, reliefs, etc. servicing cryogenic helium at temperatures as low as 2

Kelvin.

The CIC is considered a part of the EIC 591 SC’s pressure boundary, therefore construction of the CIC shall adhere to the latest relevant ASME Codes and will be subject to requirements for cleanliness, magnetic hygiene, leak tightness, and dimensional tolerance. No “U” Stamp is required.

The construction of the CIC poses a particular challenge due to the complexity of the internal piping, the need for installation of Multi-Layer Insulation (MLI), the inclusion of 2 plate-fin aluminum heat exchangers, and a minimal leak rate requirement across many welds.

This design will require the Seller and any subcontractors to follow the ASME BPVC requirements including pressure testing of the completed CIC assembly. JLAB is not requiring the Seller to “U“ stamp the CIC. Structural analysis of the CIC has been performed to show that the CIC design is compliant with the

ASME BPVC requirements and can be reviewed upon request. Should the vendor perform independent analysis to meet their internal requirements, JLAB may provide information on boundary and loading conditions.

6.2.3.2 Piping

The piping inside the CIC shall be fabricated, inspected, and tested in accordance with

ASME B31.3 for normal fluid service. The piping circuits are identified in Appendix XXXXX.

CIC cryogenic piping MAWPs at room temperature are as follows:

• Combined Return Piping 165 psig

6.2.4 Testing

The contractor shall submit detailed cold shock, pressure test and leak check procedures for approval by JLAB as part of the bid package. It is at the Seller’s discretion whether to perform tests at component or subassembly level or not.

6.2.4.3 Helium Leak Test:

1. Specific helium leak check requirements and rates are noted on relevant drawings.

2. Unless otherwise specified, cryogenic pipes inside the CIC are required to have a helium leakage not exceeding 2.0 × 10 -10 atm*cc/sec. CIC air to vacuum boundary shall not have a leak rate greater than 1.0 × 10 -9 atm*cc/sec.

3. Exception to these leak rates shall be approved by JLAB.

4. See Sec 11.3 for details.

6.2.5 Multi-Layer Insulation
