At this tirne Dr. Schreiber showed movies of the.
Kiwi-A test, During the test a failure in part of the internal mechanism
. allowed & considerably higher temperature to be reached than had been
anticipated,
However, the test was eseentially a euccess,

Kiwi-A Prime
It was brought to coo! critical last week, and plane
are to test it in Nevada in June.
Kiwi-A~-3 will follow in about two months,
?
and the main difference in Kiwi- A Prime and Kiwi-A-3 with Kiwl-A is
primarily in the coating of the holes in the graphite.
Kiwi-B-1] will be
hydrogen cooled nozzle. It will have a factor af 10 greater in power than the
‘KiwieA series, ‘It will use liquid hydrogen rather than gaseous hydrogen, .
and it is to be tested in the last half of 1961,
One thing that will delay the
testing is that it requires a new test cell to be constructed. Kiwi-B-2 will
follow by another 6 months, The primary difference here is that Kiwi-B-2_

will use pneumatic control rod actucators which do not require shielding as.
do the hydraulic type in Kiwi-B-1,

Discussion of Radiation Problems
é
Se ary
First we have to define a basic power cycle, which is one begawatt for 5
| minut¢s,
Now, if a complete callapse occurred,only 3% of the available radio- .
activity is released.
If the whole reactor is aubmerged in water even leas
radioactivity is released,
Using the basic power cycle it le possible to
runn 10,000 tests in a year and just compensate for the 2% decay in the biosphere.
