Production yield data as a function of graphite temperature

摘要

This report consists of eight curves, showing Plutonium-240 concentration and conversion ratio as a function of graphite temperature for various goal exposures. A range of 450 to 1000 degrees centigrade on the moderator temperature is used. Other parameters are consistent with the methods and constants used in present product accountability. No attempt has been made to state absolute conversion ratios or Pu-240 percentages. The purpose of this report is to provide a basis for use in economic studies involving changes in graphite temperatures. No conclusions as to operating changes should be inferred from these curves since the combined economics of any change in graphite temperatures include significant and complex factors in addition to conversion ratio and product quality consideration.
