ahd the effect of the iest results on these
requitements;
All nenber's of ile Committee, the Secretary and Mr, Tomei
were present.
Dr. Mark, Dr. Froman, and Dr, Fine also remained,
Dr. Pittman reported that the new requirement for tritium was, at
most, half of the previous requirsment.
Tritium
Hence it will not be necessary
to enrich all of the Savannah River reactors, or as many at Hanford as
planned,
Another 30-10% reduction in the requirement would make it un-
necessary to use any enriched loadings at Savannah River,
Dr. Pittman
also said that if no tritiun were required for thermonuclear weapons,
some enrichment would be required at Savannah River‘up to 1956, but none
thereafter,
.
Dr. Pittman mentioned a probable change in the manner of specifying
plutonium quality.
Plutonium
g/T vs
n/g-see
It was proposed to state the specification in terms
of the number of neutrons enitted per gram per second rather than in
terms of g/t (grams of plutonium per ton of uranium).
The definition of
high quality plutonium would be 20 n/g-sec rather than, PEARCEIVES
It was planned to fulfil the plutonium requirements by a balanced

production schedule at two levels ; 20 n/g-sec for high quality naterial,
Plutonium
Schedule and 80 n/g-sec for standard material.
