SURVEY OF THE RADIATION LEVELS IN THE CONTAINMENT VESSEL OF THE ENRICO FERMI ATOMIC POWER PLANT. PART I. GAMMA RADIATION LEVELS IN THE EQUIPMENT COMPARTMENT DUE TO PRIMARY SODIUM ACTIVITY AND ASSOCIATED FISSION PRODUCT CONTAMINATION. Technical Memorandum No. 16
The results are presented of a gamma radiation survey of the equipment compartment. The following six radioactive sources within the sodium were used: Na/sup 24/ Na/sup 22/, and four cases of fission product contamination. The four cases of fission product contamination are divided as follows: Case I-fission products from uranium occurring naturally in the scdium, Case II-fission products leaking into the sodium at 6 x 10/sup -7/ of the rate of their production Case III-fission products from dissolution of one complete pin in the primary coolant, and Case IV-fission products from the dissolution of 14 complete pins. Two conditions of the system were considered under various operating and shutdown procedures: (1) normal, and (2) drained. The calculations were made by first dividing the primary system into various discrete sources, and then computing the contributions of each source to each point on a coordinate system representing the equipment compartment. The varions conditions of the system which were considered and results of the calculations are presented. Entry into the equipment compartment under the various assumed conditions is discussed.
