Clifford, C E

The design of the removable top shield plug necessarily incorporated rather massive structural members of solid steel which penetrated straight through the shield, thus allowing a leakage path for intermediate energy neutrons. A partial mockup of the worst case, the 4 in. shell of steel surrounding the plug, was installed in the Lid Tank to determine the order of magnitude of the leakage problem. The results of the test were not encouraging. The presence of the 4-in. solid steel layer increased the emerging flux by an order of magntude over the unperforated shield for ony 13 in. of perforation. Since the results of this experiment were not encouraging, a further investigation was made for many configurations of solid steel ducts in a water shield and are reported in Part II of this memorandum.
