Area G – Safety Basis: On Monday, Area G personnel conducted a fact-finding after they determined that material-at-risk values for certain types of nitrate salt wastes may be underreported by a factor of as much as 10. Personnel determined that the historical data from the Plutonium Facility relied on safeguards values that did not accurately reflect the content of americium-241. Area G personnel are assessing the implications for the safety basis and are reviewing the extent of condition for other waste streams that may have elevated americium content.
