STUDIES OF THE DOPPLER EFFECT IN LARGE CERAMIC-FUELED FAST REACTORS

Technical Report ·
OSTI ID:4786303
;
Calculations were made of the Doppler effect in Pu/sup 239/ 0/sub 2/-U/ sup 238/0/sub 2/ and Pu/sup 239/C--U/sup 238/C--fueled fast reactors. Th e ELMOE program was employed to obtain accurate fluxes. The technique employed was to determine a critical buckling at lower temperature and to use this same buckling at higher temperature to determine k/sub eff/. The effect was not very sensitive to the presence or absence of sodium, and was not sensitive to rod size over the range studied. (M.C.G.)
