COMMERCE BUSINESS DAILY ISSUE OF OCTOBER 9,1998 PSA#2198U.S. Department of Energy, Savannah River Operations Office, Contracts
Management Division, P.O. Box A, Aiken, South Carolina 29802 99 -- GLOVEBOX INTERNALS ASSEMBLIES POC Robert Fulgham, telephone
(803) 952-6296 E-MAIL: Click here to contact Robert Fulgham via e-mail,
robert.fulgham@srs.gov. This is a notice issued by Westinghouse
Savannah River Company (WSRC), management and operating contractor for
the U.S. Department of Energy at the Savannah River Site (SRS) near
Aiken, South Carolina. The intent of this notice is to locate qualified
suppliers to perform assembly services described herein. Interested
suppliers are to include their estimated craft man-hours and the time
required for delivery in months. The services required include the
fabrication, assembly, inspection and testing of Glovebox internal
process systems (i.e., TRITIUM SERVICE) including equipment and
sub-assembly skids (i.e., piping, valves, instruments, wiring, etc.,
fully assembled) installed in Glovebox enclosures. The Gloveboxes and
major equipment are to be supplied by WSRC including the fabrication
and installation design details. The supplier will supply the bulk type
materials. The WSRC estimated quantities for the fabrication of the
sub-assembly skids and installing the equipment and skids in the
Gloveboxes are approximately: 1) 5,000 feet -- 6,000 feet tubing/piping
(majority of work is one-quarter inch through three-quarters inch); 2)
4,000 feet -- 45,00 feet polyflow tubing; 3) 400 -- 500 automatic
valves; 4) 500 -- 600 manual valves; 5) 2,000 -- 2,200 instruments; 6)
30,000 feet -- 35,000 feet control and power cable; and 7)
approximately 750 electrical feed thru's and 750 process feed thru's.
The Glovebox enclosures are designed to contain an isolated process
environment of clean dry nitrogen atmosphere at just below atmospheric
pressure. The operation of the process equipment installed inside the
Glovebox is accomplished primarily by a remotely operated distributed
control system. All maintenance of systems will be through Gloveports
installed throughout the Glovebox enclosures. Accessibility to
equipment and skid components is required for maintenance throughout
the Gloveboxes. There are three sizes of seismically qualified Glovebox
enclosures made from 7 gage 304L Stainless Steel and temperedglass
windows with gloveports. The estimated Glovebox sizes are: 1) 40 feet
long x 6 feet deep x 15 feet high; 2) 75 feet long x 6 feet deep x 15
feet high; and 3) 15 feet long x 6 feet deep x 15 feet high. The
Gloveboxes will be provided in approximately twelve (12) sections. The
Glovebox leak rate requirements must be maintained after the internal
component installation (i.e., after all the instrument and piping
associated with equipment and skids are installed and all Glovebox
penetrations are in place). The enclosures will meet a leak rate
requirement that result in an oxygen concentration rise of less than
one (1) PPM/HR starting from an initial concentration of 10 PPM with a
pressure differential of negative 1.0 inches of water. With regard to
the skid and equipment components, the typical types of components to
be installed within the Glovebox enclosures include, ASME VIII Vessels
(25 L through 2000 L), pumps, diffusers, gas dispersion equipment,
blowers, heat exchangers, pre-heaters, furnaces, purifiers, valves
(automatic & manual), flow controllers, filters, enclosures, panels,
monitors, chambers, transducers, meters, gages and other instruments
and their associated tubing, piping, electrical control and power cable
and components including their support systems. The design of the
internal components will be in a sub-assembly skid approach where
practical. The Glovebox will be built in approximately thirteen-foot
sections and assembly of skids and equipment will be done in each
section. Glovebox shell feed thru's for the electrical and piping
penetrations shall be installed by the supplier and shall meet the same
leak rate requirements as the Glovebox. Space inside the Glovebox is
limited and internal components will be congested. Highly experienced
craftsmen with the expertise to work under very confined conditions are
essential to meet the stringent quality requirements of this Project.
The Gloveboxes will be fabricated in parallel with the skids. The
supplier will assemble the skids then install the skids and other
equipment inside the Glovebox enclosures when the Gloveboxes have been
delivered to his shop. The Glovebox will then be tested and shipped to
WSRC. With regard to the skid assembly process, the supplier must have
extensive experience with hydrogen process systems (preferably
Tritium) including vacuum technology fabrication and installation
expertise. These types of systems require very stringent quality
requirements for the fabrication, installation, cleaning, inspection
and testing activities. Examples of these stringent requirements are:
1) Quality Assurance Program is required to meet ASME NQA-1 or ISO type
quality programs. 2) Shops performing these activities shall meet
special cleanliness requirements (i.e., maximum hydrocarbons on 3 foot
square surface exposed to shop atmosphere for 24 hrs or less is 25 ppm
and particulate found on 3 foot square surface exposed to shop surface
for 24 hrs is 5 NTU or less). 3) Special cleanliness requirements are
also required on external and internal surfaces of the process
equipment and appurtenances (i.e., tubing, valves, etc.). These
requirements involve Hydrocarbon Test (less than 100 ppm weight of
hydrocarbons), Halide & Suspended Solid Test (conductivity less than 10
micro ohm-cm at 20-25 degrees C) and Nephelometric Test (less than 5
NTU). Equipment and assemblies after testing are to be enclosed in
sealed containers. 4) ASME B31.3 and AMSE Section VIII are required for
process internals. Welding requires qualified procedures and welders
per ASME Section IX. The welds require "white weld" quality type welds.
These are full penetration welds which are required to have an argon
purge (less than 1% oxygen) for tubing sizes of one-quarter inch
through 1 inch with many welds having to be made under confined
conditions. The welds are required to be extensively examined including
radiography per ASME Section V, high sensitivity leak testing and no
discoloration at the root (white appearance) to assure the weld
quality. 5) Passivated piping installation may be required. 6)
Certified inspectors per national code and standards (mechanical,
electrical, controls, welding, etc.). 7) Material Certifications will
be required throughout the procurement, fabrication and assembly
activities. 8) Extensive surveillance and oversight by WSRC or WSRC's
designee. Responses to this notice are due by October 28, 1998.
