J -- DESIGN AND FABRICATION OF 30,000 GALLON LIQUID HELIUM STORAGE DEWARS POC Robert Lock, BOC-110, EG&G Florida, Inc., 407-867-7842. EG&G Florida, Inc. is seeking sources to design and fabricate two (2) 30,000 gallon liquid helium storage dewars. These dewars will be required to support launch operations at Kennedy Space Center, Fl. The minimum liquid helium capacity shall be 30,000 gallons with a 10% ullage for a total cold volume of 33,000 gallons. The maximum allowable working pressure (MAWP) shall not be less than 70 psig. A internal vaporizer shall be provided for a 63 psig ullage pressure at 75 gallon per minute flow rate of liquid helium. The normal vaporization rate shall not be more than 0.40% per day based on 30,000 gallon capacity and 85 degree F average ambient temperature. The tank insulation shall be designed for a minimum life of 20 years. A minimum of five (5) years experience will be required to demonstrate the successful operation of an insulation system design on similar 30,000 gallon liquid helium tanks. Inner vessel design and fabrication shall be in accordance with ASME Boiler and Pressure Vessel Code, Section VIII, Division I. Inner vessel material shall be 300 series stainless steel suitable for a temperature of -452 degrees F. The dewar shall have lifting lugs for placement and saddles to support it on a suitable foundation or pad. The dewar assembly and anchor bolt hole sizing shall meet the requirements for wind level of 150 MPH. (0291)
