All production facilities performed satisfactorily during December, although they were shut down for the Christmas holidays. The Purex SEFOR campaign was completed Dec 21. Redox completed solvent extraction processing of Shippingport reactor blanket fuel elements (PWR); during the first pass of PWR material, an Am-Cm fraction was separated and stored. About 720 kCi Pm-147 and 240 kCi Sr-90 were produced in Purex head end. Two STT casks were loaded with 120 kCi Cs-137 for shipment. Semiworks was used to demonstrate D2EHPA solvent extraction flowsheets for waste. Tests are underway on reduction vessel liners to reduce the crucible material for Pu recovery (two containers used inside vessel).

Data are summarized on levels of radioactivity in environmental samples collected at Hanford during 1966, including detailed data on samples collected during December. Data are included on the radioactivity in fallout from Chinese and Russian nuclear weapons test, samples of drinking water and Columbia River water, the /sup 56/Mn content of Columbia River water sampled at various locations, the /sup 131/I content of gaseous wastes and surface waters, and the radioactivity of soil samples from the chemical separations liquid waste treatment and disposal area. The radiation dose to personnel during the year from all enviromnentl sources was estimated to be less than 0.3 percent of the applicable limits. (CH)
