The accelerator operated routinely at 400 GeV during CY-1979 with about the same number of protons accelerated during CY-1979 as in CY-1978. The total number of protons accelerated in 1979 was 2.5 x 10/sup 19/. Typical operation was at about 40 percent of the design intensity of 5 x 10/sup 13/ protons per acceleration cycle. During CY-1979 there were no abnormal ocurrences. The perforated tile field at BO was sealed off and a new resin regeneration system became operational. Precipitates from the effluent are disposed of as radioactive waste. There is no evidence for any off-site impact from previous releases of any pollutant. Operation of the Central Laboratory Sewage Treatment Plant was discontinued in June 1979, and sewage was diverted to the City of Batavia Sewage Treatment Plant. The maximum potential radiation exposure at the site boundary during CY-1979 was 2 mrem compared to 11 mrem last year. This dose rate was lower because the experimental areas produced fewer off-site muons this year. The total potential radiation exposure to the general off-site population from Fermilab operations during CY-1979 was 3 man-rem compared to 5 man-rem last year. Airborne radioactivity was released across the site boundary in small amounts throughout the year. The radioactive gas was primarily /sup 11/C, total quantity released was 4 kCi, and the maximum dose at the site boundary was 1.0 mrem for 1979. The average concentration at site boundary based on measurements at the stack was 0.2% of the Concentration Guide. There was also a controlled release of tritium; the total amount released was 280 mCi. Tritium was released continuously from about June 1, 1979 (when the Meson Area resumed operations after a long shutdown) until the end of the year. The average concentration at the site boundary was about 0.00001% of the Concentration Guide, resulting in a negligible off-site exposure.
