Basic research and academic instructions in Japan in the field of
nuclear physics should be permitted subject to such surveillance as
is
[Page 284]
necessary to prevent
adaptation of possible new discoveries to war purposes.
All research or development in Japan which has for its purpose the
production of fissionable atomic species in more than minute
quantities used for research purposes should be prohibited.
All research or development in Japan which has for its purpose the
separation or concentration of fissionable species of atomic
isotopes from the naturally occurring isotope mixture of a chemical
element should be prohibited except when such isotope separation is
in minute quantities to be used for research purposes only.
All research, development, or construction in Japan which has for its
purpose the utilization of atomic nuclear energy for weapons of war
or the operation of war industries, or the operation of power
producing installations which might easily be converted to warlike
purposes, should be prohibited.
The mining, processing and refining of radioactive materials in Japan
for authorized uses should be permitted only in instances
specifically approved by SCAP and
should be under such surveillance as necessary to prevent
stockpiling of such materials for war purposes.
