85 Oil shale project small retort run summary: Run S-15 addendum computer tables1981-03Run summary; Oil shale project small retort; Lawrence Livermore LaboratoryThe Run Summary for S-15 was published quite some time ago (UCID 18282-Sept. 1979). At that time we had not completely analyzed the data using the computer as we had done in other run summaries. We have now gone back and processed that data. This report presents the computer generated run summary da...
