Request for Information (RFI)

Savannah River Nuclear Solutions, LLC (SRNS), which manages and operates portions of the Savannah River Site (SRS) under a Department of Energy (DOE) prime contract, solicits expressions of interest from potential suppliers who have a strong background in the design, fabrication, and installation of blowers in an industrial application.

This RFI is issued to assist with finding potential suppliers interested in this solicitation.

The SRS is located approximately 15 miles south of Aiken, South Carolina and is 310 contiguous square miles.

Scope Summary: Provide labor, materials, and services required for the design, fabrication, inspection, testing, documentation, delivery, installation support, and technical startup support of three (3) glovebox stripper blower/motor assembly units.

1. The word “shall” is used to denote a requirement.


2. The phrase “shall consider” is used when an objective assessment is to be performed in the subsequent response to the request for interest, to determine to what extent the specified consideration can be met. The basis for incorporation or rejection of the consideration shall be provided in the response to the request for interest.


3. The word “will” is a statement of fact or a declaration of purpose.

Requirements are as follows:

1. Supply three (3) glovebox stripper blower/motor assembly units.


2. Description of Process Fluid:
   
   
   
   1. High-purity (99.5%) nitrogen with trace oxygen and hydrogen isotopes.
   
   
   2. High-purity argon.
   
   
   
   

Description of Blower/Motor Assembly installation Location:

1. Blower/Motor assembly will be installed within a nitrogen inerted glovebox.


2. Blower/Motor assembly will be anchored to the stainless-steel working deck of the glovebox.


3. Motor shall be detachable from the blower assembly.


4. Each blower/motor assembly shall have sealed greased bearings. Liquid oil cooling/lube shall not be used.


5. The high activity blower/motor assembly will process nitrogen/argon gas based on an inlet temperature of 20-30 deg C.


6. Each blower/motor assembly shall have a flow rate between 100-140 SCFM and a Differential Pressure of approximately 5.5 PSIG.


7. Each blower/motor assembly shall be hermetically sealed or shall have a Leak Rate of 0.1 PSIG change over 10 minutes at 50 PSIG.


8. Each motor shall be TEFC rated.


9. Motor shall fit through a glovebox window that is 34” high and 30” wide.


10. Blower/motor material shall be approved by the Design Agency.
    
    
    
    1. Powders shall not be used
    
    
    2. Insulation, cloth, fabrics, polymers, ceramics, etc. that appear to generate particulate matter shall not be used.
    
    
    3. Plain carbon steels shall not be used.
    
    
    4. Ferritic stainless steels, martensitic stainless steels, and precipitation hardening austenitic stainless steels shall not be used.
    
    
    
    

Considerations are as follows:

1. Vendor shall consider Vibration/Temperature instrumentation to be included in package.


2. Vendor shall consider a minimum design pressure rating of 100 psig for the Blower. Lower design pressures will be considered.


3. Vendor shall consider maximum envelope size for overall footprint including base to not exceed 60” L x 36 “W x 32” H.


4. Vendor shall consider the motor to be of minimal size. Vendor shall consider that the motor can fit through an airlock that is 18.5” L x 19.6” W x 15.875” H.


5. Vendor shall consider Blower to have vertical flange connections with 4” diameter.


6. Vendor shall consider Blower/motor assembly to incorporate a separate motor that is magnetically coupled to the blower.


7. Vendor shall consider that existing Blowers are currently run on standard three-phase, 60 Hz, 230/460 VAC power and are seismically anchored to pads welded to the floor of the glovebox.


8. Vendor shall consider motor weight to be under 50 lbs. Heavier motor weights will be considered.


9. Vendor shall consider Blower/motor assembly and associated equipment to be designed to limit sound pressure levels at or below 75 dB(A).


10. Vendor shall consider that electrical equipment purchased is to be UL Listed, FM Approved, “listed” by an Occupation Safety and Health Administration (OSHA) approved nationally recognized testing laboratory (NRTL).


11. Vendor shall consider blower/motor assemblies that do not incorporate an enclosure/housing.
