, 1962 The tests performed on a full-scale prototype of the closure designed for the Pathfinder reactor vessel are described. This head was bolted to another head designed to simulate the reactor vessel. The design pressure of the facility is 700 psig at 500 deg F. Strain gages and brittle coatings were used to determine the stresses in the closure.
