3. The bottom,, which may or may not be removable, depending on 

 the final design, will have four fluid entries. 



k. The vessel operating pressure will be 20,000 psi at any temperature 

 between 0°C and + UO°Co 



Depending on the costs involved in lining the vessel and the end 

 closures with a material which is unaffected by sea water, this vessel 

 may be provided with a pliable bag and basket system similar to that 

 used in the 9-inch vessel and shown in Figure ik. 



The vessel will be provided with an air-operated circulating sea- 

 water supply system similar to that used with the 9"inch vessel. It 

 is planned that this vessel will ultimately be provided with a refrigeration 

 system and an automatic pressure-control and pressure=cycling system. 



The procurement, installation, and development of this system has 

 been planned as follows: 



Phase I - Fy-62 



a. Design and procurement of the vessel. 



b. Alteration of an existing building to accommodate the 

 vessel system. (Completed) 



Phase II = FY=63 



a. Installation of the vessel. 



b. Fabrication and installation of a controlled sea-water 

 supply system. 



c. Procurement of refrigeration equipment. 



d. Procurement of temperature-control equipment. 



e. Installation of a cooling system. 

 Phase III - FY-64 



a. Procurement and installation of an electronic salinity 

 and oxygen monitoring system. 



b. Procurement and installation of pressure -cycling pumping 

 and control equipment. 



The vessel should be available for initial use late in FY-63.
