66 -- SELF-SHIELDING CO-60 IRRADIATOR SOL 53SBNB060065 DUE 050100 POC Brenda K. Lee (301) 975-6394 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) intends to procure a Shelf-Shielding Co-60 Irradiator using simplified acquisition procedures, under the authority of the test program for certain commercial items cited in FAR Surpart 13.5, Test Program for Certain Commercial Items. The Standard Industrial Classification (SIC) code is 3829 and the size standard is 500 employees. This action is unrestricted. The Government requires a new irradiator to provide high-dose calibrations. It is used to provide calibration services for the sterilization and electronic hardness testing industry. The radioactive source decays at a rate of 50% every five years, therefore it must be periodically replaced to meet the demands of the minimum dose rate to satisfy customer needs. This device will replace an existing irradiator so it must be similar to prevent unnecessary disruption in the calibrations. NIST need a self-shielding with similar design and properties of the current gammacell 220-232, but loaded with the maximum dose rate possible. The sources shall be 60 Co with a total activity of at least 24, 000 Ci. The sources shall be contained in 12 or more double-encapsulated stainless steel rods in a fixed annular array. The array shall be inside a lead-steel biological shield. The dose rate shall be uniform throughout the chamber within plus/minus 20% of the central dose rate. The dose rate shall be uniform in the center of the chamber so that the physical center volume 5cm diameter x 5-cm height has a dose uniformity of plus/minus one percent. This uniformity shall be verified by NIST measurements two times; once prior to the source being shipped from the manufacturer. Shielding -- The unit shall provide shielding such that leakage exposure is less than 2mR/h at one meter in any direction from the center of the source array. Detailed specifications shall be provided in the solicitation. FOB Destination, Gaithersburg, MD. Required delivery within 120 days from contract award. The Government requires a 12 month warranty on all parts and labor. Warranty shall begin when the unit has passed acceptance testing. On-site services/maintenance shall be provided for a period of 12 month after acceptance. On-sites services shall include a maximum of 3 business day's turnaround from call to on-site service during warranty period. The Government requires a complete set of operation and maintenance manuals with circuit diagrams and parts list. The Government requires on-site measurement of the units prior to shipping. This will involve NIST personnel measuring the central dose rate with alanine dosimeters and measuring the field uniformity with sheets of radiochromic film. The Government requires installation and set-up, capability demonstration, accepting testing and on-site training for 2 or more employees. The capability demonstration and on-site training shall be performed by the field service engineer. The Contractor shall demonstrate that the system meets or exceed all performance specifications identified in the solicitation. The unit shall successfully pass the capability demonstration before final acceptance. Award will be based on the offeror whose proposal offers the best value to the Government, technical, price, and other factors considered. The Government intends to issue a Request for Quotation (RFQ). Requests for a copy of the RFQ may be mailed to the National Institute of Standards and Technology, Acquisition and Assistance Division, Building 301, Room B117, 100 Bureau Drive, Stop 3572, Gaithersburg, Maryland 20899-0001, Reference Solicitation No. 53SBNB060065 or faxed to (301) 963-7732 or sent through the email link below. The response date identified above is an estimate. The RFQ will be available approximately fifteen days after publication of this announcement and the solicitation response time will be approximately 15 days after issuance. All responsible sources may submit a quotation, which will be considered by the agency. All requests for the solicitation package must be in writing. Faxed quotation willnot be accepted.
