SUMMARY OF TASK UNIT ACTIVITIES

TASK UNIT 2,
4.2.1
UCRL PROGRAMS
Objectives.
Tu-2 was organized to field UCRL-designed weapons and
nuclear devices and to carry out diagnostic experiments designed
to measure certain of their properties.
4.2.2
Techniques.
The techniques used to obtain the various measurements are
described briefly in Chapter 2, Section 2.3.
They are also
described, in much greater detail in the preoperational and .
technical reports of the various programs.

a
Operations,
The concept of UCRL and LASL limiting their activities to
separate atolls was introduced for the first time in Hardtack.
It proved to be a very satisfactory arrangement for the major
portion of the operation,
though a combination of factors re-
sulted in the necessity of shifting several UCRL shots to
Eniwetok during the latter stages of the program.
Chief among
the factors requiring UCRL to shift devices to Eniwetok was
the tight production schedules encountered in the fabrication
of devices and the inherentiy poorer shooting weather encountered
at Bikini when compared to Eniwetok.
Much of the diagnostic
support required at Eniwetok was provided by EG&@; without this
eupport the two-atoll operation would not have been possible.
