Familisrization with equipment used on Tumbler-Snapper and
detection of methods of improvement were a valuable part of the
training program for Operation Ivy.
Some of the equipment operated
satisfactorily and will be used on Ivy without change. Other equip~ ~
ment will require further laboratory testing and radical modification
prior to its use in Ivy.

These tests included trial hydrogen
fillings of the reflux system.
The piping system is being revised
as a result of the experience gained in the filling operations.
Another hydrogen filling is scheduled for July.
At this time the
piping layout will duplicate the proposed Eniwetok layout as closely
as possible.
