H -- DEVELOP MICRO BG PU-239 IN ARTIFICIAL URINE STANDARD REFERENCE PERFORMANCE EVALUATION TEST MATERIALS SOL 52SBNB7C1007 DUE 112296 POC Kathleen Lettofsky (301) 975-6342 The National Institute of Standards and Technology (NIST) intends to negotiate on a sole source basis under the authority of 41 USC 253(c)(1) the services of Yankee Atomic Electric Company (YAEL), Bolton, Massachusetts to produce NIST traceable radiobioassay quality assurance/control samples for ultra-low level plutonium metrology techniques testing. It is anticipated that only YAEL can satisfy the requirement because only YAEL has a team of individuals who can focus the required interdisciplinary expertise in radionuclide metrology and ability to confirm the Pu-239 dilutions over eight orders of magnitude in artificial urine. The tasks to be performed are: (1) dilution of NIST Pu-239 SRM to mBq/g levels; (2) confirmation of the dilutions by NIST traceable low level isotope dilution alpha-particle spectroscopy to a total propagated uncertainty of less than 2 percent (2S); (3) preparation of the artificial urine per ANSI N13.30 protocol; (4) further dilution of the Pu-239 test solutions with the artificial urine to microBq/kg concentrations; (5) confirmation of the artificial urine dilutions by NIST traceable low level gamma-ray spectroscopy to a total propagated uncertainty of less than 2 percent (2S); and (6) full evaluation and propagation of measurement and dilution uncertainties per NIST protocol for certification of the test materials. Delivery shall be 100 days from date of award. Interested offerors may identify their interest and capability to respond to the requirements by submitting a capability statement. The capability statement must provide adequate information and qualifications to provide this type of service. All of the above must be received for the Government to consider whether to open this requirement for competition. This notice of intent is not a requirement for competitive proposals. However, all ''capability statements'' received within 45 days after date of preparation of this synopsis will be considered by the Government. A solicitation is not available. See Numbered Note 22 and 26. (0282)
