A -- DESIGN, FABRICATE AND TEST IN-LINE/ON-LINE RADIONUCLIDE DETECTOR SOL ES-0209 DUE 032200 POC Larry Coffey, (803) 952-8855 E-MAIL: Click here to contact Larry Coffey via e-mail, lawrence.coffey@srs.gov. Westinghouse Savannah River Company (WSRC), Management and Operating contractor for the U.S. Department of Energy's (DOE) Savannah River Site (SRS) located near Aiken, South Carolina, is seeking expressions of interest from potential subcontractors for the design, fabrication, testing and operational support of in-line/on-line radionuclide detection monitor system. The system may consist of multiple detectors. The fabricated equipment will be installed in a heavily shielded, remotely operated facility at SRS due to the high radiation source of the process. Demonstration of capability to meet and conform to the following minimum criteria will be required: 1) All engineering is to be performed at the subcontractor's facility or through partnership with WSRC. 2) Individual components may be subcontracted to a lower-tier supplier, but final assembly must be at the prime subcontractor's facility. 3) The process equipment will be operating in a highly radioactive environment. Radiological evaluation to determine the useful life of the components will be required. Experience in this area is desirable. 4) The process will be monitored for the following: a) Alpha (transuranics) emitting isotopes in concentration range from 1 to 100 nCi/ml in the presence of up to 45 nCi/ml of gamma emitters. The minimum detection limit for alpha will be no greater than 10 nCi/ml at a 95% confidence level and a maximum count time of 6 hours. b) Alpha (transuranics) emitting isotopes in concentration range from 1 to 100 nCi/ml in the presence of up to 1300 nCi/ml of gamma emitters. The minimum detection limit for alpha will be no greater than 10 nCi/ml at a 95% confidence level and a maximum count time of 6 hours. c) Cs-137 and Sr-90 in the presence of up to 20 nCi/ml of other gamma emitters. The expected Sr-90 concentration range is 1-40 nCi/ml. The expected Cs-137 concentration is 1-100 nCi/ml. The minimum detection limit for Cs-137 will be no greater than 10 nCi/ml and Sr-90 will be no greater than 4 nCi/ml. Both detection limits will be at a 95% confidence level and a maximum count time of 6 hours. 6) The flow rate of the process streams to be monitored will be 0.1 to 0.5 gpm. 7) The detectors, connectors, and associated cables shall be capable of operating in up to 100% humidity. 8) The monitor shall be capable of operating in temperatures up to 40 degrees C. 9) The detectors will be capable of being installed on/in a 3-inch (nominal) schedule 40 pipe. The prime subcontractor must be ISO 9000 qualified or must have a Quality Assurance program approved or capable of being approved by WSRC. If teaming with other organizations, indicate the capabilities of each team organization and provide any information relating to successful prior teaming experience. A Time and Materials or Cost Type subcontract is contemplated. The expressions of interest must be received by WSRC on or before March 22, 2000, and should reference Solicitation No. ES-0209. Responses can be transmitted via regular mail to Westinghouse Savannah River Company, ATTN: Larry Coffey, Building 730-4B, Room 2170, Aiken, SC 29808; via fax to (803) 952-6092; or via e-mail to lawrence.coffey@srs.gov. This is a request for Expressions of Interest only; it is not a request for a formal proposal. Posted 03/06/00 (W-SN431347). (0066)
