99 -- REMOTE PRESSURE MONITORING TECHNOLOGY FOR SEALED FUEL STORAGE CONTAINER -- EXPRESSION OF INTEREST SOL 98-005 DUE 100998 POC D. R. Duncan, Spent Nuclear Fuel Project, Duke Engineering & Services, Hanford, Inc., 509-372-1013 WEB: Fluor Daniel Hanford Acquisitions, http://www.hanford.gov/pmm. E-MAIL: Technical Point of Contact, darrel_r_duncan@rl.gov. Duke Engineering & Services Hanford, Inc., under subcontract to Fluor Daniel Hanford, Inc., the prime contractor to the U.S. Department of Energy (DOE), Richland Operations Office, is seeking information regarding instrumentation technologies capable of remote pressure sensing from the interior of sealed spent fuel storage containers. The application requires sensing of internal gas pressure from within each of up to 400 spent nuclear fuel storage containers (termed multi-canister overpacks or MCOs) during a 40 year interim storage period within a dry storage vault. The MCO is a 24 inch diameter stainless steel shell with an internal storage cavity length of approximately 11.7 feet, a welded bottom plate, and a top shield plug. No active process penetrations will exist in the shield plug. The wall thickness is nominally inch. The internal storage volume will be largely filled with stainless steel baskets containing fuel assemblies; some total free volume of a minimum of 0.5 m3 will exist. Informational sketches will be supplied upon request. The instrumentation is expected to be operational for at least the entire 40 year storage period. The MCOs will be stored in pairs in concrete vault tubes of 28 inch interior diameter, with a sealed plug at the top of the tube. Readout must be accomplished external to the MCO without physical penetration of the MCO wall. The temperature range of interest is from 0 -- 250 F, the MCO internal atmosphere will be a mixture of helium, hydrogen, oxygen, and water vapor whose composition will vary with time and with each particular MCO. The maximum radiation field expected is approximately 1000 R/hr. The desired application is pressure sensing with a target accuracy of +/- 25 psi over a range of 0-1000 psi, however less accuracy will be considered. The approximate delivery date for sensing equipment would be May 2000. This is not a request for proposal, but a request for information. Interested offerors are requested to submit information regarding the basic technology, accuracy and range of applicability, in addition to previous history and applications, including references. If any information presented by the offeror is proprietary it should be so marked and separated from the unrestricted information. Any information should be provided within 20 days of this announcement. Information may be submitted via mail, electronically, or by fax. All contacts should be made with D.R.Duncan, Spent Nuclear Fuel Project, MSIN R3-86, Building MO285/200E Area, Richland, Washington 99352; telephone (509) 372-1013 and fax (509) 373-9774. Electronic mail should be sent to: Darrel_R_Duncan@rl.gov. Posted 09/17/98 (W-SN251128). (0260)
